Winter Garden
Add guillotine glass, sliding glass or zip screens beneath a glass roof. A winter garden is a light-filled room you use in every season.

Overview
A winter garden is not one product but a combination of systems that work together. On top, the LUMEN GLS R-300 fixed glass roof keeps out rain, snow and cold while letting light in. On the fronts, VISTA GLS G-200 guillotine glass keeps the view open and THERMA SLD T-400 double-glazed sliding glass adds thermal and acoustic insulation.
In summer, a SKYLINE ZIP C-100 ceiling blind under the glass filters the sun and reduces heat gain. In the evening, LED lighting turns the winter garden into a warm living space.
All profiles are made in the same RAL colour. Try out which combination suits your space, by day and by night, in the Combination Studio.

FAQ
Which glass system should I choose for a winter garden?
For views and wide openings choose VISTA guillotine glass, for thermal and acoustic insulation THERMA double-glazed sliding glass, and for a slim look LINEA single-glass sliding. Different sides can use different systems.
Does a winter garden get hot in summer?
A SKYLINE ceiling zip blind under the glass filters the sun and reduces heat gain, and opening the guillotine or sliding glass ventilates the room.
How deep can the glass roof be?
The LUMEN glass roof projects up to 4 m; above 4 m width an intermediate post is added.
