Glass

Our standard glass is high performance, low emissivity specially made for double glazed units only. The coating is extremely neutral in appearance and reflects long wave heat radiation back into the room. The coating is applied to the glass surface on the inside of the cavity and maximises solar heat gain from outside and minimises heat loss from within the room.

The process uses a magnetron device, coated in the UK. It apples a combination of multiple metal oxide layers to the high quality glass using a magnetically enhanced cathodic sputtering process under vacuum.

The glass is assembled into finished units in Cornwall with specially developed spacer and desiccant to avoid misting.

The assembled 4:20:4 configuration is filled with argon gas to maximise the thermal insulation and achieve our best in class u value of 1.1 W/m2K.

Self cleaning glass

Put the chore of window cleaning behind you thanks to low-maintenance, self-cleaning glass!

How does it work?

A transparent coating on the outside of the glass harnesses the power of both sun and rain to efficiently remove dirt and grime. Exposure to the UV rays present in daylight triggers the decomposition of organic dirt and prevents mineral dirt from adhering to the surface of the glass. It also turns it “hydrophilic” meaning that when it rains the water sheets across the glass, without forming droplets, rinsing away the broken down dirty residues. Only a small amount of sunlight is required to activate the coating so the self-cleaning function will work even on cloudy days. A simple rinse of water during dry spells will help keep windows clean.

Benefits

Self-cleaning glass does not need to be cleaned as frequently as normal glass. However it is not 100% maintenance free. It is kept clean using natural elements present in UV light from the sun and rain so the “chore” of window cleaning is considerably reduced.

Self-cleaning glass can be combined with other products for multi-functional glazing, such as thermal and solar control, noise reduction and enhanced safety and security.

Other options

We have a wide range of options available including toughened, tinted and solar control please contact our experts for further information on 01209 215 759

Georgian Bars

We are able to offer conventional straight or curved Georgian bars fitted in the glass cavity or surface mounted Georgian bars on the outside and inside surface of the glass for a more authentic look.

Leaded windows

We can offer a wide range of leaded windows from classic patterns to custom designed units from artwork templates.

Special shapes

Because not all windows are rectangular, we can supply windows to fit many shapes and curves.
