Weather Performance

Q-Lon plyurethane foam seals ensure weather performance, keeping draughts and wind driven rain outside, while keeping you warm inside. Rubber gasket beads provide a secondary weather seal helping Warmcore exceed the requirements of BS6375-1 (the classification for weather tightness on windows and doors).

U-Values

A U-Value is a measure of heat loss through a structural element. it is calculated on the rate at which heat transfers through 1 square metre of a structure and is stated in W/m2K.

 

 

 

U-Values are used by the construction industry to compare the thermal performance of different materials and products.

Current building regulations require a U-Value of 1.6.

Double Glazing has a U-Value of 1.3.

Warmcore Aluminium windows have a U-Value of 0.8 when combined with triple glazing.

Tilt & Turn

The WarmCore system is available as a tilt and turn window. Ideal for upstairs use, tilt and turn windows can be tilted inwards for ventilation or swung inwards for a wider opening.

 

Using multi-point locking and custom designed hinges, tilt and turn windows are as safe and secure as the rest of the WarmCore range.

Flush Sash

WarmCore casement windows are available in a ‘flush sash’ option for the ultimate in clean, modern aesthetics.

 

Using a stepped outer frame, the sash – the opening part of the window – sites on the same plane as the rest of the window, creating a pure, cutting-edge look. Where two flush sashes meet, WarmCore uses a feature mullion, creating a precise bead link in-between the two windows.
