Glass has a significant effect on the heat your house loses at night, the heat it gains during the day and noise levels from outside. Glass helps to determine the level of comfort, security and privacy in your home.
No matter where your site is located or the positioning of the windows within a project, The Folding Sliding Door Company provides you with many glass solutions.
Our standards are high
Double glazed, argon filled, Low-E coated toughened (tempered) glass, 28mm constructed units fitted with Super Spacer® Bars
4mm toughened glass outside, 20mm cavity and 4mm toughened Low-E glass inside.
Low-E (K) coating on the inside, gives the glass better thermal properties and allows most natural light to enter freely but reflects a significant portion of short-wave heat energy. In summer, long-wave heat energy radiating from objects is reflected back outside, lowering cooling cost. In winter, internal longwave heat energy is reflected back inside, lowering heating costs.
Toughened glass is a safety glass, shatters into small pieces, is about 4 times stronger than standard glass, is resistance to thermal stress and impact resistance. Argon, has a 34% lower thermal conductivity than air.
Super Spacer® bars
Standard windows use a highly conductive metal spacer bar to hold the two panes of glass apart, which sucks heat from inside to the outside. Super Spacer® is a no-metal warm edge, pre-desiccated, structural foam spacer system which allows for expansion and contraction (a major cause of fractures in conventional sealed units).
We offer a huge selection of glass, each with its own unique thermal U-Value properties, some specific to your door choice, our sales team can readily advise.
