ClimaGuard® A+ Low E Glass
Our standard glazing is ClimaGuard® A+ low emissivity (Low-E) glass, designed to improve energy efficiency and comfort in your home.
It helps protect against heat loss in winter and reduces excess heat in summer, lowering energy consumption and costs. The glass also enhances natural light, reduces noise, and improves safety and security.
With excellent light transmission and solar control, it maximises daylight while maintaining comfortable indoor temperatures. It also meets the latest UK building regulations introduced in June 2022 for improved energy performance and reduced carbon emissions.
ClimaGuard® A+ allows solar heat to enter your home and retains it inside, helping to reduce heating bills during colder months.

Glazing Bars
Our flat astragal bars can be positioned over cavity duplex spacer bars and are bonded to the external faces of the sealed unit to authentically replicate the appearance of Art Deco style glazing.
Available in 25mm and 41mm widths the aluminium astragal bars can be powder coated to match the frame colour and be applied in horizontal or vertical layouts and cruciform grids to give the appearance of multiple sealed units.
Lead Work
If you require lead work details to sealed units we are able to recreate existing designs using traditional materials and techniques including antique aged lead work with soldered joints.
Lead work can also be combined with coloured and patterned films, bevels and obscure glass to produce unique designs to suit contemporary properties or to create a traditional stained glass effect.
