SL 45

For a unique way of opening up

Overview

SL 45 bi-folding door

One section of the panel opens inwards, the other outwards

What makes the SL 45 non-insulated bi-folding door truly special is its range of different opening options: one section of the panel opens inwards, the other outwards. An optional turn-and-tilt panel can be included in the system to make ventilation easier.

Two seal levels provide optimum insulation against the wind and rain - the perfect shelter for any patio or balcony. The built-in Solarlux convenience lock with handle, bolt-catch lock with profile cylinder, and locking bolt guarantees a high level of anti-burglary protection.
