The most impressive range of bi-fold and lift & slide doors just got even better for even more possibilities.

aïr 500LS and 600LS doors offer a slimmer sash and interlock that’s 40 percent slimmer than that of other leading aluminium sliding doors, but its engineering offers boundless opportunities for design.

aïr is designed for large openings with an impressive 2.5m maximum sash width. With wider panes of glass and less frame, homeowners can make the most of captivating views from their home.

The look is completed with aïrcoat, a dirt resistant, textured paint available in a range of colours which adds a stunning finish to aïr doors. aïr doesn’t only stand out in terms of its aesthetic, but also offers superior performance, with U-values as low as 1.0 and aïrtight interlocking weather seals to keep bad weather at bay. It’s engineered with stainless steel rollers and aïrglide technology, so glass panes weighing up to 300kg can be pushed open using the pressure of just 2 fingers.

Safety and security is taken care of too, with the clever aïrlock, a PAS 24 standard locking system and anti-finger trap technology. Plus, there’s an industry-leading 25-year manufacturer’s guarantee for extra peace of mind.

Come and see the aïrzone at the Everglade showroom in West London, where there are 11 sets of aïr doors on display for you and your customers.
