Engineered to the highest standards

Slender aluminium profiles combine with highly insulated glass units, giving you some of the most energy-efficient sliding doors on the market.

Warm in winter, stunning in the summer

It's the glass that's just one clue to the impressive specifications of Cortizo sliding doors. You get toughened safety glass, having a soft-coat low-emissivity coating, warm edge spacer bars and argon gas fill. The result is U-Values designed to keep you comfortable in the winter, cooler in the summer and save money on your energy bills.  You can also upgrade the glass to triple glazing, laminated, acoustic or solar control. The thin aluminium profiles come with built-in insulation preventing cold bridging and providing enhanced insulation throughout.  In the winter months, sophisticated seals, hidden drainage and clever design protects your home from the cold, wind and rain.
