• Within England, Approved Document L, Conservation of fuel and power now requires replacement windows of dwellings to have a maximum whole window u value of 1.4 W/(m2·K) or minimum Window Energy Rating (WER) Band B. The requirement is for a whole window rating taking into account all the materials used to make the window.
• Our windows meet this requirement as standard with a 1.4 W/(m2·K) u value or lower (WER ‘A’). This is achieved through the use of a 5-Chambered profile system and Low-emissivity coated 28mm double glazed unit with warm edge spacer.

Handle:

The handle acts as a restrictor, holds the window open 150mm for ventilation and snaps down in place to lock, there is no key needed.

The handle is removed for transport. There are four screws included which you can screw into premade holes with a Philips screwdriver by hand once the window is held in place with packers which are provided. Please make sure to fit the handle after packing the frame into the opening and check it operates correctly before sealing in place with silicone.

• Low E Glass Coating:
• PLANIBEL A is a revolutionary new hard coating that meets the highest glass performance expectations for Window Energy Ratings (WERs).
• Along with argon gas filling this helps to keep your home warm in the winter, cool in the summer and reduce energy bills.
• (Comes with a 10 year guarantee against failing)

• We use a warm edge Black soft spacer. Warm edge spacers help to drastically reduce heat loss through the edge of the glass where up to 80% of the heat escapes as well as reducing condensation on and around the glass.
