What is Warm Edge?
Warm Edge is a spacer made from an insulating plastic composite material which is thermally optimised to prevent heat escaping through the edge of the double or triple glazed unit.
What is Warm Edge used for?
Warm Edge is at the heart of the energy saving window. It separates the panes of glass in sealed units and keeps the sealed unit’s edge warm by reducing heat loss through the window. Less heat loss means lower heating bills and a more comfortable indoor temperature.
Is SWISSPACER suitable for WERs?
Yes! SWISSPACER is a cost-effective way of getting excellent energy ratings. It often makes the difference between one level of WERs and the next and can easily lift a window from a ‘C’ to a ‘B’ and a ‘B’ to an ‘A’.
What benefits does SWISSPACER have over other warm edge spacer bars?
SWISSPACER is tried and tested worldwide. Its next generation spacer bar – ULTIMATE – was best for thermal performance in independent ift Rosenheim tests of all the leading foiled warm edge spacer bars. The tests were conducted for the Warm Edge Group of Bundesverband Flachglas to which all the leading warm edge producers belong. SWISSPACER V came 2nd! Importantly, SWISSPACER’s performance lasts. All SWISSPACER spacer bars have a Gas Tight Barrier that keeps moisture vapour out and insulating gas inside the unit. SWISSPACER helps energy rated windows perform and save money for years.
Is SWISSPACER suitable for triple glazing?
SWISSPACER is ideal for triple glazing – its rigid structure is strong enough to cope with the extra weight of a third pane of glass. SWISSPACER is tried and tested in triple glazing across Europe including Germany, where triple glazing accounts for 40% of the market.
Do sealed unit makers need specialist machinery to use SWISSPACER?
No. Unlike some warm edge spacer brands, you don’t need to invest in any specialist machinery to use SWISSPACER. SWISSPACER has the same external dimensions as aluminium spacer bars so it can be used with cut and corner keys straight ‘out of the box’ on existing machinery or by hand. Large scale sealed unit makers can choose from a range of high performance welders and benders. High productivity welders from ROTTLER & RUDIGER give fully-automated production with perfect 90°angles, producing a single frame in just 30 seconds.
How many colours is SWISSPACER available in?
SWISSPACER has the widest range of colours available from stock – 17 in total.
Why is there condensation on my windows?
If you have single glazed or older double glazed windows with aluminium spacer bars in the sealed unit, you might see condensation on the inside of your windows, especially in the mornings. Aluminium spacer bars are highly conductive and allow heat to pass through the window, so the edges of the sealed unit are colder than the rest of the window. When it’s cold outside the moisture we breathe and produce from cooking and everyday living condenses on the coldest surface in the home, usually on the inside of the window.
Why is there mould on my windows?
Over time persistent condensation becomes a breeding ground for mould and bacteria. It’s not just unsightly - mould spores get into the air we breathe and can aggravate breathing conditions and other health problems. SWISSPACER warm edge spacer bars almost eliminates the risk of condensation and mould forming on the inside of windows. SWISSPACER keeps the edge of the sealed unit warm so condensation can’t form.
How can I prevent condensation and mould on my windows?
You can reduce condensation by keeping your home well-ventilated. The optimum indoor humidity level is 40-50% with an indoor temperature of 20°C. Open your windows regularly, even when it’s raining. When using the bathroom or cooking, keep the windows open and turn on extractor fans. If your windows have narrow slits in the frame (called trickle ventilators) keep these open. Try to dry your clothes outside and when using a tumble drier, ensure the warm air is vented outside. If condensation and mould is a persistent problem, consider replacing your windows with sealed units with SWISSPACER inside, which almost eliminates the risk of condensation forming.
There is condensation on the outside of my windows – why?
Double or triple glazing can be such an effective insulator that while the inside pane of glass is warm to the touch, so little heat escapes to the outside pane that it becomes very cold. In rare instances where external atmospheric conditions raise local humidity levels above saturation, moisture condenses on the coldest surface. In unusual cases this may be the outside pane of glass of a window. Being outside it causes no damage and is a sign of the energy efficiency of your window.
