Superior Thermal Performance:
At the heart of WarmCore products is a thermal core which significantly out-performs the polyamide thermal breaks commonly used to reduce the threat of cold bridging on aluminium windows and doors. The result is an innovative 'warm aluminium' frame construction, carefully dimensioned to provide an optimised 70mm front-to-back overall sash frame depth while ensuring market-leading thermal performance thanks to the multi-chambered insulating core.
Fully concealed multi-chambered cores substantially improve thermal performance when compared to thermally-broken aluminium doors:
U-value of 1.4 W/m2K with 28mm double glazing
U-value of 1.0 W/m2K with 44mm Triple glazing
Warmer By Design:
WarmCore has been designed from the ground up to offer market-leading thermal performance, and comfortably meets the requirements of Building Regulations - Part L. Traditional aluminium doors struggle to meet current legislation, forcing you to choose aluminium aesthetics and finish over thermal performance. WarmCore gives you both, with its innovative full width thermal core.
This unique composite construction creates the most thermally efficient folding sliding door in its class. This design philosophy has produced a folding sliding door that has exceptional thermal performance, helping keep fuel bills lower and heat in your home, while retaining the sleek and architectural look of aluminium.
Triple glazing - for ultimate thermal performance:
Robustly designed to take the weight of triple glazed units as standard, choose this option for the ultimate thermal performance - at least 75% better than standard double glazed aluminium folding sliding doors. Opting for 44mm triple glazing rather than standard 28mm double glazing reduces the whole door U-Value rating from 1.4 to 1.0. Triple glazing is ideal for WarmCore doors installed in exposed locations.
Using standard double glazing the WarmCore folding sliding door achieves a U-value of 1.5, with U-values as low as 1.0 achievable using 44mm triple glazing. The advantage against traditional aluminium doors is clear, with many struggling to meet current legislation.
