Triple Glazing Option - For The Ultimate Thermal Performance
Our aluminium bi-folds are 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.
Can you supply 10-foot french patio doors? We are quite often asked for this combination and this door is our closet option. At ten foot wide two doors are going to be too big so the solution is a 4 pane door that works with three panes that slide to the left or right and one fixed door. This gives you a set of french doors at approximately 1500mm and another pair that can slide if required to the left or right.
