An important choice to make when purchasing your doors is what type of glass to put in them
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
4mm 1/4" toughened glass outside, 20mm 3/4" cavity and 4mm 1/4" 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 value properties, some specific to your door choice, our sales team can readily advise.
Triple-glazed units, low-e coated toughened glass
For increased thermal & acoustic properties, as well as increasing security. Our triple glazing units use 4mm 1/4" toughened glass outside, 8mm 3/8"cavity, 4mm 1/4"toughened, 8mm 3/8"cavity, 4mm 1/4" toughened Low-E glass on the inside
Laminated Glass / Impact Glass
Laminate resists penetration – glass may break but the plastic inner layer retains overall integrity and continues to act as a barrier.
(1) Protects against break-ins by preventing or slowing down burglary attempts.
(2) Withstands repeated blows from heavy objects such as bricks, hammers, crowbars and similar hand held heavy objects. Depending on the extent of the attack, the product remains integral and protects the premises adequately and limits penetration whilst awaiting replacement.
Georgian Bars (STL's)
Placed between two panes of glass (UK) on either side of the unit (US), achieving a Georgian window style, available in different designs, sizes and colors
This has the benefit of larger surface glass areas for cleaning (UK)
Designs – Horizontal, Traditional Georgian Grid or Bespoke
Colors – White, Rosewood, Black, Grey, Cream & Light oak (UK)
Transoms are horizontal glazing bars that match the profile of the door. It divides the glass into two separate units, a unit at the top and a unit at the bottom of each door panel.
Transoms are 80mm ( 3 5/32" ) wide for Aluminum/uPVC and 60mm wide for timber doors.
The Transom is built into the panel at your indicated measurement, from the bottom of the panel to the center of the transom
Mullions are vertical glazing bars that match the profile of the door. It divides the glass into two separate units, a unit to the left and a unit to the right of each door panel.
Mullions are 80mm ( 3 5/32" ) wide for Aluminum/uPVC and 60mm ( 3 3/8" ) wide for timber doors.
The Mullion is built into the panel at your indicated measurement, from the left of the panel to the center of the mullion.
Deep Bottom Rail / Kick Panel
Set within the door frame,
Colours available in grey, bronze, green and blue
