Overview
The warmest glass room we make
A fixed glass room combines a permanent, double-glazed glass roof with glass walls and doors to create a fully enclosed glass garden room. With no moving roof, it offers the highest insulation of our glass rooms and is ideal as a kitchen extension, dining room or garden office.
The aluminium structure is designed for British wind and snow loads, with integrated gutters and concealed drainage. Walls can be fixed glass, sliding patio doors, bifold doors or frameless sliding glass.
Add external roof blinds to control summer heat and LED lighting for evenings.
