Alitherm Plus Residential Doors

Our modern range of entrance doors will impress your guests and keep out both the elements and unwelcome intruders. Our Alitherm Plus doors are designed for use as open out or open in, single or double doors, internally or externally beaded with side-light and low threshold options.

Elegant, yet strong and durable Alitherm doors enhance the beauty of your home, keep in the warmth and let in more light because of the slim sightlines. Peace of mind is ensured by the enhanced security provided by a multi-point locking system and with our adjustable SFS hinges.

At 1st Class we always try to specify the best hardware and make our products as easy to fit as possible. With this in mind, we always recommend that you specify a 20mm extension profile on the hinge side of each door. This ensures that the hinges have plenty of clearance with plaster lines on the inside or external brickwork on the outside.
