Visofold Doors

The Smart Visofold 1000 creates an impressive opening that can unite internal and external areas, creating a bright, open living space. Suitable for both domestic and commercial projects.

All Visofold profiles feature a polyamide thermal break that enhances the thermal performance of the profile and improves the overall U-Value. Profiles feature EPDM high quality gaskets and weather brushes to aid weather resistance. Visofold complies with the requirements of Building Regulations Document L 2010. Security is assured by multi-point lock mechanisms on main opening sashes, and shoot-bolt locking on floating mullions.
