Glazing options

Sashed glazing units

You have a choice of glazing options depending on product type. Individual product types can accommodate different types of glazing, for example sliding patio doors are deep enough to accommodate triple glazing, where as standard sliding sash windows only can accommodate double glazing. The majority of our timber windows and doors come with either 22mm or 18mm double glazed units. Our 22mm double glazing units consist of 4mm glass on the outside, 16mm space filled with Argon gas to prevent heat transfer and 4mm glass on the inside (4/16Ar/4), offering excellent U-Values with soft coat low emission (low-e) Argon filled units and a centre pane U-Value of 1.1 W/m²K. Our 18mm glazing units consist of 4mm glass on the outside, 10mm space filled with Argon and 4mm glass on the inside (4/10Ar/4) and a centre pane U-Value of 1.4 W/m²K.
Our standard triple glazed products are glazed with Low-E Argon gas filled units. The standard triple glazing units consist of 4mm glass on the outside, 8mm space filled with Argon gas to prevent heat transfer, another 4mm of glass, another 8mm space filled with Argon gas, and 4mm glass on the inside (4/8Ar/4/8Ar/4). Our triple glazed products offer superior U-Values with soft coat low emission (low-e) Argon filled units and a centre pane U-Value of 1.0 W/m²K.
Centre pane U-Values as low as 0.5 W/m²K can be achieved by using triple glazing units consisting of 4mm glass on the outside, 18mm space filled with Argon gas to prevent heat transfer, another 4mm of glass, another 18mm space filled with Argon gas, and 4mm glass on the inside (4/18Ar/4/18Ar/4). We can use this type of triple glazing in sliding patio doors.
Triple glazing is the ideal choice for large glazing areas as it allows maximum glazing sizes with minimum heat loss. The improved sound installation of triple glazed units can also increase the acoustic performance. Triple glazing makes the glazing unit very thick and heavy and in most instances its not possible to use triple glazing; please contact us for more details on your individual use case.

Toughened glass

Sometimes toughened glass is required to comply with building regulations. Toughened glass is up to five times as strong as ordinary glass which means that it has to be hit much harder in order to break, and if it does break then it will break into lots of small pieces which are much less dangerous.

Laminated glass

Laminated glass has the same strength as ordinary glass but it consists of two pieces of glass with a sandwich of plastic interlayer. If the glass breaks, the fragments of glass are held in place by the interlayer. In fully framed installations the broken glass retains a residual strength while awaiting replacement. Laminated glass is available upon request.

Frosted and obscured patterned glass

Glazing is an important design element for any building and can make all the difference when creating a feature window or door. It can also make a significant difference to your privacy. In addition to frosted glass we offer a variety of obscure glazing patterns which are available in different designs offering various levels of privacy. We use Glass Solutions from Saint-Gobain, which is a leading manufacturer of glass throughout Europe. You can choose from the following options:

Specialist Glass

We can also supply specialist glass such as intelligent glazing, self-cleaning glass, extra clear low iron glass, acoustic glass or even solar control glass.

Glazing spacer bars (Warm Edge Spacers)

Glazing spacer bars is the name given to the edge of a sealed double or triple glazed unit. Spacer bars are used to separate the panes of glass by a specific gap and it’s what you see when you look inside your double glazed unit. For many years the standard spacer bar was made from aluminium, which conducts heat or cold, this can lead to higher levels of thermal loss and a reduction of energy efficiency. In recent years, double and triple glazing has moved away from the colder aluminium spacer bars and embraced warm edge spacer technology. Warm edge spacer is a term given to a slightly different type of spacer bar. The term warm edge is based on the fact that the construction is fabricated and designed to conduct less heat or cold than the traditional aluminium spacer tubes. Units fabricated using warm edge spacers can have a warmer internal edge temperature of up to 65%, reducing the likelihood of condensation by up to 70% and increasing thermal efficiency.
We use warm edge spacers on all our products as standard, and do not use aluminium spacers except where requested or where the limitation of glass type means aluminium spacers are the only option.
Warm edge spacers come in a wide rage of colours, and unless a specific colour is requested we automatically select the colour of spacer bar to match the paint colour. For example products which are white inside and outside will have white warm edge spacers.
