We use Pilkington’s Optiwhite E glass externally and soft coated K Glass internally. Our Optiwhite E glass is specially developed float glass which displays none of the green taint found in many standard ‘clear’ glasses. Our internally soft coated K glass offers excellent thermal insulation as the heat bounces off the glass and back into the internal living space. Our standard glass unit has a u-value of 1.2W/m2k – the overall u-value depends on the u-value of the given window frame.
Argon Gas Filled Glass
You have the option to upgrade your glass unit to be argon gas filled. Argon gas is a lot denser than air, which results in greater energy efficiency and a lower u-value. Argon is an inexpensive, non-toxic odourless gas which prevents frost from occurring at the bottom of the window and at the same time it will improve the sound-proofing characteristics of the window.
Increase the strength of the glass unit by upgrading to toughened glass. The products that are subject to accidental human impact for example our bi-folding doors come with safety toughened glass as standard. Toughened glass is achieved by subjecting the unit to a heating and cooling treatment whereby high compressive stresses are set up at the surfaces with balancing tensile stresses in the centre.
Our acoustic laminated glass is a glass solution that offers excellent noise reduction. The desired performance is achieved by combining various thickness of glass with a special polyvinylbutyral interlayer. Our laminated glass unit comes with Argon filled gas as standard. We recommend laminated glass in areas with excess noise from road, rail or air traffic or other sources such as factories or nightclubs.

We offer three different spacer bar colours: Black, White or Grey. The purpose of the spacer bar is to hold the two panes of glass apart. The system we use is a non-metal, pre-desiccated, structural foam spacer, which enables our windows to achieve the highest energy ratings.
