Door Designer


At Truglaze we’re impressed by every product we sell, but when it comes to WarmCore aluminium folding sliding doors, we’re downright awestruck. They are without doubt, true pioneers of contemporary design, but here’s where it gets really clever. They’ve introduced a rather nifty type of thermal technology that lets your home retain up to 25% more heat than their closest rivals’ doors.

You not only get exceptional design; huge choice, and all the security features you’d expect from a first-class manufacturer, you can also expect a significant reduction in your fuel bills.

Robust, extraordinarily beautiful, and completely versatile, WarmCore is the first choice for those looking for something extra special.
