At The Window Merchants we are pushing the boundaries further than ever to create the perfect windows for today, and the future. The combination of profile, trickle vents and glass has made our windows and doors compliant and will continue to meet the planned changes in building regulations in the future.

Glass >>>
Low E glass works by acting as a barrier to long wave heat radiation whilst maintaining a high transmission of short wave radiation. This allows the natural light from the sun to enter through the window just like normal float glass but traps the heat generated within the house reducing heat loss. The glass surfaces ability to radiate long wave energy is called its emissitivity. The lower the emission the lower the heat loss.

Furniture >>>
Handles on fire escape windows non-locking with a hinge that allows the window to open 90 degrees giving a clear opening for escape. Locking systems must include a facility for night vent positioning or trickle vents are required

Profile >>>
The frame work be it in upvc or other materials need to achieve a certain level of thermal efficiency. On pvcu this is achieved by the chambers segregating the inside from the outside of the profile.

Trickle vents >>>
All new houses, including extensions, require trickle vents in all windows. Habitable rooms i.e. lounges and bedrooms require a background ventilation of 8000mm2 of free air. Non habitation rooms i.e. kitchens and bathrooms 4000mm2 of free air.
