Unlike standard doors, many of which divide as opposed to connect, aïr have engineered aïr bi-folding doors and sliding doors to bridge together interior and exterior spaces. These doors maximise the look and feel of interior spaces while capturing natural light and projecting it throughout your home. Aïr are progressive in our design and engineering. This allows us to achieve large door panels and customisable door frames which include energy-saving technologies, advanced security, and durability backed by the manufacturer’s guarantee of up to 25 years

As well as stylish aesthetics, aïr doors have innovative security features, with high-security, multipoint locking as well as PAS 24 and the police-approved Secured by Design accreditations so you can have peace of mind that your home is safe and secure. This gives you the assurance that your sliding doors achieve the latest requirements for enhanced security performance, without having to compromise on style. The slimline aluminium frames of aïr lift and slide doors come in more than 400 RAL colours and you can also choose from special aïrcoat paint that offers a textured finish that’s dirt and scratch resistant – protecting the doors from daily wear and tear. To take the design of your sliding doors one step further, you can have dual colour frames, so that you can complement both the interior and exterior of your home.
