We only build winter gardens with wood/aluminum sections known as “Lara”, a brand produced by Gutmann. The wood in these sections fulfills the load-bearing structural task. Besides this, a materials comparison between plastic, wood and aluminum shows that wood has the best energy efficiency rating. Outside, the complex wood construction is protected using aluminum sections. This technique helps prevent condensation and thermal bridges.
We usually design doors with lifting or sliding components that can also bear heavy glass loads. If the structure as a whole is designed correctly, outer walls (or glass walls) can be pushed partially or even entirely to one side.
One should not forget, however, that shade and ventilation are decisive for the future popularity of your room combining the inside with the outside. We plan both of these from the beginning. It makes sense to, for example, install automatic ventilators controlled by temperature- and humidity gauges. In summer this ensures that extra warmth can be directed outside the house, whereas in winter the extra warmth can be piped from the winter garden into adjacent rooms.
