Vacuum Glazing, Double Glazing & Triple Glazing types
We offer the best of all glazing options available – Vacuum Glazing, Double Glazing & Triple Glazing.
Many companies use a dry double glazing gasket system which soon shrinks and rots in a short space of time, leaving you with leaks and problems. Our 100% water proof & energy efficient glazing method, which is unique to us, and is approved by the Glass & Glazing Federation, is a tried and tested method over many decades, which combines the use of butyl and silicone.
Our system has never failed our customers once, and ensures two superior seals around your glass, so you can be sure that there are no leaks or problems, ever. Our 14mm slim glass is sealed with true putty and painted over, just like the originals 100 years ago.
Will Vacuum Glass Replace Double Glazing?
In short, the answer I think is, yes, vacuum glazing will replace traditional double glazing, to some extent.
Vacuum glass is certainly a much better solution for better energy efficiency and Building Regulation compliance for wooden windows and doors than either double glazing or triple glazing. Vacuum glass is also needed to avoid being forced to use triple glazing as triple glazing is not a technically viable solution as the hardware required for windows and doors simply can not accomodate the weight of triple glazing, not to mention it is extremely bulky and ugly!
Vacuum glass is MUCH thinner, lighter and is more energy efficient than both Double glazing AND Triple glazing
The downside is that Vacuum glazing takes a long time to make (in late 2024 it takes us approx 12 weeks to get this glass) so orders will take a lot longer because of the limited amount of Vacuum glass manufacturers at present. It is also much more expensive, but we assume the price will get more competetive as time goes by.
For softwood windows and doors, Vacuum glass is usually not required to meet the current 2024 Building Regulations. But it (or triple glazing) is required for most Hardwood windows and doors, as this new Vacuum glazing over compensates for the lack of energy efficiency of hardwood, so it makes hardwood windows and doors compliant. This avoids the need for triple glazing which is very heavy, bulky and ugly.
Double Glazing Glass Types 24mm
Double glazing glass is one of the biggest factors in energy savings these days. Our glass surpasses all UK requirements and standards. Our 24mm double glazed, argon filled, Guardian Glass, has been tested and passed BSI EN1279 certification.
The most cost effective double glazing measures 24mm overall, not 20mm and not 28mm. Our 24mm optimal glass is made up with a 4mm LowE soft coat inner pane – 16mm argon gas filled air gap with warm edge spacer bars – and 4mm float glass to the outer pane. This gives the glass a u-value rating of 1.0 to 1.1 wm²k. Our “Climaguard Premium Info” glass is made by “Guardian Glass”. It is used as standard in our products. Our toughened or laminated safety glass usually comes stamped to show you it is safety glass, otherwise it will be certified as such.
Incorporating warm edge spacer systems we are able to achieve optimal energy efficiency values. These warm edge spacer bars come in either black or white. We always recommend the black spacer bar as it looks neater and sharper, even if the windows or doors are white. Some manufacturers will use and offer you 20mm Double Glazing, which does look slimmer, but be aware that the energy efficiency deteriorates when if the Argon gas cavity is smaller than 16mm.
How low-E glass works on warm days
Sun’s direct intensity, short wave infrared heat energy, strikes the glass surface and surroundings converting this energy into long wave (low energy) infrared heat.
The Low-E coating assists in rejecting this heat back outside.
How low-E glass works on cold days
Typical oil bar heater energy and stored energy being released from floors (this stored energy may passively collect during the day from the sun’s direct transmission.
The Low-E coating assists in reflecting this heat back inside.
Heritage slim glass 14mm
Our heritage sash window, pictured here, is glazed the old fashioned way with separate glass units glazed into the sash Georgian bars with real putty. Once the units are sprigged and puttied into position, the glass is taped up and the windows get another coat of paint to protect the putty and blend it in with the frame.
The Heritage super spacer is used to achieve minimal sight lines. The glass is very slim at 14mm (4mmLowE – 6mm Krypton – 4mm float) and is filled with Krypton gas as this is the best energy efficient solution for slim double glazing glass.
As you can see these sash windows look like the originals and the double glazing is almost invisible.
Perfectly suited for Listed Buildings and Conservation areas to maintain the true heritage appeal.
