imageClayton Glass have just produced a new 20-page Product Guide that’s packed with their expanded range of SMARTGLASS® products for the conservatory, bi-folding and patio door sectors, including the latest ground breaking, self-tinting Dynamic glass.

The new Product Guide includes technical performance characteristics of their market leading conservatory roof glass range, that now includes the flagship Ultra 86 solution, which is they believe, the best performing glass of its type in the UK market at present. It boats a G-value of 14% and like all products in the SMARTGLASS® roof range, comes with warm edge technology and true self cleaning properties as standard.

SMARTGLASS®-W is the industry’s first dedicated range of glass for conservatory frames which is also detailed in the new guide and it’s also designed for the bi-folding and patio door market. The key property of this product is the fact that it is designed to vastly reduce the impact of solar heat gain, a characteristic certainly not welcomed in any conservatory environment.

The recently launched SMARTGLASS® Dynamic product, is the industry’s first automatically self-tinting, glass technology for conservatories, Orangeries and other glazing elements and is also detailed in the Product Guide. With availability in any shape and a 10-14 day turnaround on orders, along with a clever interactive market tool, it’s a new development that’s already generating considerable interest.

Jason McCabe, commercial and site director for Clayton Glass commented: ‘The Product Guide is very much the bible for conservatory, bi-folding and patio door glass with our unrivalled SMARTGLASS® range. There are technical tables and charts, along with flagship products that really help set us apart and make us the glass partner of choice in the sector.’

SMARTGLASS-WThe SMARTGLASS® brand from Clayton Glass is synonymous with cutting edge performance of glass in conservatories and now the same technology has been bought to the bi-folding and patio door markets, with SMARTGLASS®W.

Typically, the glass used in ‘A’ rated and above windows is designed with an element of solar heat gain within the calculations. This is all well and good in typical domestic properties for replacement windows, but where there are large areas of glass, this is the exact opposite of what is required from a technical standpoint, when there is on average 5m2 of glass in a typical bi-folding door that is 2100mm high x 3000mm wide, assuming 80% glass coverage.

SMARTGLASS®W has been designed to minimise solar heat gain in bi-folding and patio doors, along with all conservatory side frames and there are three variants in the range. All boast warm edge technology, argon filling and a U-value of 1.0W/m2K, with enhanced versions offering anti-fade properties, true self-cleaning properties, along with enhanced acoustics and security.

The cost differential between the entry level SMARTGLASS®W and the typical glass used in ‘A’ rated windows is marginal, yet the performance differential is considerable. There’s also the benefit of deliveries direct to site to any UK mainland postcode within the Clayton Glass fleet of vehicles, 5 days a week and with am delivery option.

Jason McCabe, commercial and site director of Clayton Glass commented: ‘We’re a market leader by example and our SMARTGLASS®W product fully reflects our vision as a glass innovator and pioneer. Technically better performing glass for bi-folding and patio doors is great for the sector, with the obvious sell on opportunities for installation businesses eager to capitalise on a sales hook.’

The latest Palmer Report suggest that the conservatory market is once again returning to growth after 11 years of decline. Jason McCabe, commercial director of Clayton Glass highlights current conservatory design and convention and outlines his vision for the future.

Much has been discussed about the plight of the conservatory sector and at it’s peak a good proportion of the 300,000 installations were small, polycarbonate glazed designs. They proved to be cheap additions for homeowners looking to add valuable extended living space into what is in comparison to our European neighbours, a very small footprint.

But today’s conservatory is very much different in terms of specification and design and so is now attracting new types of consumers. There are those that will be second or even third time conservatory buyers who like the light and airy nature of a conservatory, yet want to benefit from the latest value added accessories.

But the sector is also attracting first time buyers, who now like the appeal of these new accessories, but also the new foiled finishes and they even fully embrace the latest glass technologies, such as those found in our unparalleled SMARTGLASS range.  Glass is at the very heart of these latest conservatory designs and polycarbonate as a roofing material has fallen away at the same rate as the conservatory sector, with glass now accounting for around 80% of all installations, with this proportion increasing year on year.

But what does the modern day conservatory look like? The definition isn’t so clear cut with a number of add-ons available, including the latest internal perimeter ceilings as conservatory design morphs into that of the traditional single story extension market and so the builders market and that of the typical conservatory installer, moves every closer.

These new internal perimeter ceilings are a perfect means to add spotlights and they also add a degree of insulation at the eaves. When combined with the new fashion for brick piers and the adoption of a gutter shroud, the humble PVCu conservatory looks more like cleverly engineered, design-led additional living space. In addition to brick piers we have also seen the emergence of Loggia, which is a range of insulated corner posts in a range of colours, adopts architectural design and supports the desire from consumers for more colour.

The market for rooflights has also grown strongly in recent years from a very niche market to one in which most of the major systems companies are now fully engaged, with some manufacturers now boasting over one hundred each and every week. Many kitchen extensions now for example incorporate a rooflight and a large set of bi-folding doors, the clearest indication yet that we are as obsessed about the back of our houses as the front.

We have also seen the emergence of the tiled roof sector, which those involved in their manufacture and specification will claim that their sales will surpass those of conservatories, something that I’m not sure will happen. I believe hybrid roofs are the next obvious step combining the solid feel of a tiled roof with the opportunity for glazing apertures in key locations in the roof.

Indeed, I have heard a number of instances where installation companies have followed up enquiries for these new solid, tiled roofs only to sell them a value added and feature rich conservatory. This all goes to suggest that consumers love the appeal of glass, after all it’s our link to the world outside. The latest research from Velux, global leaders in roof windows, further emphasizes this proposition, stating that 68 per cent of UK residents rate the amount of daylight entering a property as ‘important’ or ‘very important’ when looking for a new home.

While our SMARTGLASS range has become a market leader in the sector, we are still looking to push the boundaries in what we can achieve in glass. SMARTGLASS-W is the first ever dedicated range of glass for conservatory doors and windows and has been designed to minimize solar heat gain in stark contrast to the glass used in ‘A’ rated windows for example. We’ve even been able to incorporate all of the features from our specialist roof glass, to help make for a single glazing solution throughout the entire conservatory.

But for those of you that want a sneak preview of the glazing for the future, you should visit our stand at the FIT Show in the Innovation Zone on stand A30. We’ll be launching SMARTGLASS Dynamic, powered by SageGlass, the industry’s first commercially viable switchable glass for rooflights.

FIT Show First with Sage Glass Installation at Telford


In a dramatic move to provide a live-showcase for its product, US-based manufacturer of electronically tintable SageGlass® is introducing the product to the UK at a trade show for the glass and glazing industries by replacing an entire glass wall at the Telford exhibition centre home of the event.

132 conventional glass units with a total area of 314 metres2 will be replaced permanently with SageGlass® Lightzone™ in advance of the launch of the product at The Fabricator Installer Trade (FIT) Show, the trade event for the UK window, door, glass and conservatory industries. The installation will allow the real-world demonstration of SageGlass Lightzone, which allows the creation of up to three variable tint zones within a single pane of glass, throughout the three days of the event which takes place on 12th, 13th and 14th April 2016 at The International Centre, Telford.

When installed the glass will be automatically controlled by four external light sensors which detect predetermined light levels at which the SageGlass will tint from the clear state of 60% light transmission, in four stages down to only 1% light transmission. All cable and controls are integrated in to the system and are easily installed in the existing curtain walling. Tinting and therefore light levels may be also controlled through a special SageGlass Mobile App.

SageGlass, a product of Saint-Gobain, the leading producer of flat glass in Europe and number two worldwide, chose the event and the dramatic decision to install its product ahead of the show due to the concentration of glazing industry professionals that will be attending The FIT Show.

In addition, the company’s partner on the UK Conservatory market, County Durham based Clayton Glass, will be featuring SageGlass on its stand at the event.

A New Glass Era for Conservatories

We’re not just looking at specialist glass for roofs, but now the whole glazed area for conservatories, explains Jason McCabe, commercial director of Clayton Glass, the company behind the dominant SMARTGLASS® brand. 

The dynamics in the conservatory sector have fundamentally changed over the last decade. As volumes have fallen back slightly, the adoption of specialist glass as a roofing material has grown impressively and it now dominates sales for installation companies. Conservatory sizes have also increased, as have the overall specifications for conservatories, so what’s next?

With the increased adoption of larger and more complex shapes, along with new foiled finishes, the typical white 3×3 polycarbonate glazed conservatories seem to be a legacy of the last decade, which isn’t necessarily a bad thing. Margins were tight and product innovation was lacking and so the increase in specifications and adoption of pseudo-orangeries in recent years has bolstered the prospects for many.

But I believe one of the biggest changes in the way we both manufacture and promote conservatories is about to happen in the form of technically balanced glazing throughout the entire conservatory and that includes all doors, windows and gable ends. It is with this in mind that we created SMARTGLASS®W, the sector’s first dedicated range of clear glass specifically designed for conservatory doors and windows.

The considerable developments in glass over recent years have been able to do much to regulate the temperature gain through the conservatory roof, but have not yet been transferred to the vertical plane. Often instead, in part due to the influence of Window Energy Ratings scheme, and in part due to a lack of knowledge or just for ease, typically C or even A-Rated specifications may be used as the default.

Although this can help in the winter, such products are actually designed to give a good level degree of solar heat gain, something clearly unwanted during the summer in a conservatory environment. Faced with 3 externally glazed areas the issue is magnified and often problematic, hence the development of our new wall glasses which, exactly like our roof range, tackle both the summer heat and the winter cold in the same unit.

While the very first Victorian conservatories were designed to house tropical plants, the modern derivative is designed to offer a cost effective glazed extension to the home and a link to the world outside. Conservatories have and do suffer from the issues of solar heat gain, harmful UV rays and organic dirt, which have been addressed in the roofing area, but up until now not for the doors and windows in the vertical plane.

The launch of a dedicated range of specialist glass for conservatory walls is something our customers are eager to take up. Everyone is happy as installers can differentiate and increase margins, whilst the homeowner gains a genuinely better engineered and more temperate glazed extension to the home. The additional cost to upgrade from Low E glass to standard SMARTGLASS-W for example is moderate, yet the performance differential is huge within a conservatory.

As we continue to look at new ways in which to develop specialist glass solutions, our standard SMARTGLASS-W glass offering for conservatory side frames is almost 3 times better than standard clear glass for heat retention, offers 227% more solar control than standard clear glass and benefits from warm edge technology. We believe this should be the minimum standard for all conservatory door and window glazing in the future.

As much of the specialist conservatory roof glass on the market can seem over complex, in common with our SMARTGLASS roofs we’ve kept our new range to a simple 3-tier strategy. Added value features such as enhanced security and acoustics and the ability to block out 98% of the sun’s harmful UV rays are included as the range progresses.  Bleaching and physical damage to soft furnishings can be almost totally eliminated through the side walls and we’ve even added a flagship product that offers the same true self cleaning technology in the doors and windows, as well as in the roofing area.

I firmly believe that we are entering a new glass era for conservatories and one in which will offer consumers a complete, smarter glazed solution throughout. As an industry we need to innovate to ensure we keep on attracting new first time buyers of conservatories and importantly, those second time purchasers who will be primed for some of the latest upgrades both in glass specification and in the overall design of a conservatory. While the growth in the newly emerging solid insulated roof market is strong, conservatories and the desire for a glazed extension still dominates the consumer sector.


SMARTGLASS -WClayton Glass have just launched SMARTGLASS®W, the industry’s first dedicated range of glass that’s been specifically designed for conservatory doors and windows.

SMARTGLASS® has become the dominant brand for conservatory roof glass over the last 10 years, offering a range of products that are unsurpassed in terms of performance and backed by the product quality and operational accuracy that they have become renowned for. By working closely with their customer base of systems companies, fabricators and installers, the company has developed SMARTGLASS®W which offers consumers the same market leading performance in their side frames and their conservatory roof together, as a complete package.

Sold with a three tier proposition, the standard SMARTGLASS®W typically offers 240% more solar control than standard glass, is almost 3 times better than clear glass for heat retention and benefits from warm edge technology. The upgrade to SMARTGLASS®W Plus+ additionally provides enhanced security and acoustics, and blocks out 98% of the sun’s harmful UV rays, which have proven to damage soft furnishings in conservatories over the years. Better still SMARTGLASS®W Ultimate offers all these key features, along with a true self-clean coating, helping conservatory owners enjoy a clear vision of the world outside.

There has already been considerable interest from a number of existing customers, eager to look for the upselling opportunities with SMARTGLASS®W and the promise of offering a better solution for a fully glazed conservatory.

Jason McCabe, commercial director of Clayton Glass commented: ‘SMARTGLASS®W has been developed to provide a better conservatory environment for consumers. The days of cheap polycarbonate based conservatories is long gone and the future for the conservatory sector is through innovation as our new product range shows.

He continues: ‘Even ‘A’ rated windows fall considerable short in the performance tables to SMARTGLASS®W and the increase in cost is marginal in relative terms. We believe that with as much glazed area in the vertical plane as in the horizontal (roof) plane, the future in conservatories is for a total solar control solution from floor to roof.’

Ultra83Clayton Glass has recently launched SMARTGLASS® Ultra 83, which they claim is the industry’s most advanced solar control, true self-cleaning glass for conservatory roofs and rooflights. 

The market for specialist conservatory roof glass is really only twelve years old, yet the developments in products over the last two years have been significant and the SMARTGLASS® range has very much led the way. SMARTGLASS® Ultra 83 is now the benchmark for all round performance with warm edge technology, a u-value of 1.0 W/m2K, g-value (solar control) of just 17% and combined with a good level of light transmittance at 25%.

The key to choosing high performance roof glass is about ‘selectivity’, in this case by reducing the solar energy able to enter the structure, yet allowing sufficient light transmission to ensure an open and airy feel, the very fundamental proposition of a glazed extension.

For the last few years SMARTGLASS® has been quietly building market share and the brand is now widely recognised and respected, boasting customers such as Connaught Conservatory Roofs, Prefix Systems and Tailored Roofing Systems. The once 1.4 W/m2K standard for conservatory roof glass has now been replaced by 1.2 W/m2K, with a recent move towards the 1.0 W/m2K SMARTGLASS® range, all with true self clean and warm edge technology offered as standard.

There are impressive glass features available from all the leading European flat glass manufacturers and as a fully independent processor, it’s the role of Clayton Glass as experts, to harness all the best technologies into a single SMARTGLASS® insulated glass unit.

Jason McCabe, commercial director of Clayton Glass commented: ‘SMARTGLASS® Ultra 83 is the result of our research into cutting edge products, thanks to our pan-European network of partners. It’s credentials are unsurpassed and it’s the flagship in our SMARTGLASS® range which includes SMARTGLASS®, SMARTGLASS® Plus+ and SMARTGLASS® Ultimate.’

SMARTGLASS raises the bar – Again!

SMARTGLASSAs a truly independent manufacturer we are able to research and procure on a European wide scale so we are once again delighted to announce we’re bringing a new product to market that challenges the limits of glass technology, throwing down the gauntlet to all other roof manufacturers.

This continual R+D process made our highly successful Ultimate Blue a UK first, and now brings an even better, more enhanced version of our best selling roof glass to market.

Blue glassNaturally deep blue tinted and of course with warm edge, true self clean and argon as standard, SMARTGLASSS TM Ultra 83 is our most effective solar control glass to date. With a G-Value of just a 17% it is a massive 15% better than the next best product on the market, reflecting 83% of the sun’s heat – once again setting the standard by which all other roof glasses can be judged. It’s available for installation now, and you will only find this level of performance from Clayton Glass, Northern Express Glass and our downstream customer base.

Rest assured whilst everyone else sells the same old basic blue, as a SMARTGLASSTM customer you’ll always have access to the most cutting edge technology, so you can always promise to fit the best – with confidence.

Discontinuation of Energy Surcharge

After 10 years of the levy being applied separately, Pilkington and most other major glass manufacturers have decided to end the practice of charging an Energy Surcharge on the glass they sell. From November this year therefore, the glass we buy will be on an ‘all inclusive’ basis, and thus we ourselves and all other downstream processors will be able to revert back to the old position of an all-inclusive IG rate.

This will provide greater transparency and remove the need to add two numbers to get to the real price, which is what in practice we all do anyway whether buying or selling.

As there will be no effect on the net selling price we don’t have a deadline date for implementation, but over the coming weeks we will be replacing all existing tariffs with a view to everyone being ‘all inclusive’ by the end of November. Energy will simply be rolled back into the price at today’s level so while m2 rates will appear to rise, there will be an equal reduction in the surcharge at the foot of the invoice.

We welcome this simplification of structure which will be a benefit to us all in the long term, but please don’t hesitate to contact your account manager should you have any questions.


Autumn and Glazing Viewing Criteria

As we move again towards the colder shorter days, and low light of Autumn we’re reminded of the seasonal glass issues that this time of year can bring for installers. Last Autumn we published some guidelines on external condensation, we hope you found this useful and its posted again here as a reminder.

This year I’d briefly like to look at the effect of the morning and evening sun, its temporary effect on the visuals of installed glass and thus the importance of glass manufacturer, installer and customer all operating to the same standardised inspection criteria.

This really struck me whilst driving home in bright Autumn sun, through a tree lined street last week. I became suddenly aware that the sky was teaming with thousands, millions of particles – it literally looked like the attack of the midgies. Tiny flies, grains of dust, and pollen were shining like millions of little lights in front of me and for a second it was a bit alarming, as if an insects nest had been disturbed and they were swarming all over.

Suddenly the sun went behind a tree and it all disappeared, instantly.  When the bright and direct light disappeared, so did the flies. Or actually they didn’t –  it just dawned on me that they are always there, it’s just only under extreme lighting conditions could they be seen so vividly.

This incident brought to mind the problems that can be associated with glass units, when viewed in extreme light.

It’s the time of year where we are getting a few instances each week where we are being asked for replacements due to marks in cavity, from installations many months previous. The home owner was assumedly happy with their glass and windows for several months, but on certain days, at certain times of year and from certain angles small marks, streaks or other visual effects are apparent.

The Glass & Glazing Federation inspection criteria to which we adhere says of viewing conditions:

 ‘Do so in natural daylight, but not directly towards the sun and with no visible moisture on the surface of the glass’

Ignoring these instructions and viewing in direct sunlight, and especially at an oblique angle to the glass, will almost certainly result in otherwise invisible visual effects being noticeable, such as:

  • A bloom or haze illuminating the cavity (This is the low E surface catching the light)
  • Milky or dusty appearance
  • The accentuation of small scratches and particles

Just a reminder therefore to encourage all staff and customers to be aware of and to follow these instructions when considering whether a unit should be replaced not. We often offer site visits but are told only to come at certain times of the day when the sun is round – this should always ring alarm bells.

  •  View in daylight but not direct sunlight
  • View at right-angles to the glass, from 2 metres
  • Look through not at the glass

If these instructions are not followed properly, then almost certainly both installer and IGU supplier are going to spend time and money which could be avoided with the right understanding of inspection criteria.

The Energy Surcharge for the quarter commencing 1st February 2014 will be calculated based on the closing value of IPE Brent on January 15th 2014.

EnergiMAX brand to be rolled out

ENERGIMAXBranding on our standard insulating glass unit range is to be changed to EnergiMAX TM reflecting the almost total move to 1.2 centre pane u-value product now supplied.

With most customers having dropped the low iron element of ‘A’ rated some time ago, the brand in its current state has become less and less relevant over the last year in particular. We’ve hence decided to widen its remit to cover all argon filled Softcoat sealed units made by Clayton Glass, and our sister company Northern Express Glass. All units of this type will therefore carry to the branding and label above.

It remains our strong intention as a business to continue to research and develop the most energy efficient products, and with triple glazing coming more to the fore we hope to launch EnergiMAX Triple Glazed in the coming months, subject to a more comprehensive view of how this will sit within the WER scale.

Product Update: Triple Glazed Insulating Glass Units

Over the past few years we’ve become one of the North of England’s biggest manufacturers of triple glazing, and now have two fully automated lines for their manufacture. One of the key issues to understand with triple glazing however is that unless you have the optimum cavities, gas filling, proper equipment and  correct glass combinations you  may well end up with a unit that has no significant thermal advantage of the DGU equivalent,  yet is just more costly, heavier and prone to failure.

 To quantify this, our current standard Planitherm DGU has a centre pane U value of 1.2, so we’ve tailored our triple glazed range to be significantly better than this base unit.  Using just one leaf of Planitherm in a TG unit will at best improve the U value to 1.0 but by simply adding an extra pane of clear glass, the triple glazed equivalent will almost certainly perform worse under a WER scenario.

 Our most popular Triple Glazed units therefore use two leaves of Planitherm Total +, with coating on face 3 and 5. Both cavities are argon filled, the middle leaf is always toughened for thermal safety and we are currently in the process of developing a range to include anti condensation – you will probably have had calls from customers complaining about this effect at this time of year?

 Using these combinations, our 36mm version offers a centre pane U value of 0.8, and the 44mm version a class leading 0.6.  We can of course tailor a unit to your exact requirements, so if you would like to know more or to discuss price,  I would be happy to come and talk to you further. In the meantime I’ve attached a chart below graphing the various relative performances.
