Notes on building a photovoltaic sunroom:
1. If the housing area is large, especially in villa-type buildings, the sunroom is mainly used for winter leisure and fitness. , gardening, etc., it is better to choose an integral mobile sunroom with a removable roof. This type of sunroom will not have the problem of poor lighting in the insulation board type sunroom or the high indoor temperature in the summer of the fixed lighting roof type sunroom.
< p>2. If the housing area is small, in order to expand the living space and the leisure sunroom needs to be built with high privacy and low economic level, you can choose products such as insulation board roof, plastic steel doors and windows and insulation walls for peripheral maintenance. Although it is not a sun room in the strict sense, it is cheap, economical and practical. The disadvantage is that the lighting is poor and the ventilation is average. It will be greatly improved if a skylight is added.3. If the sun room is mainly built for winter. Growing flowers and grass requires the sun room to have good ventilation and appropriate sunlight. It is better to use plastic steel windows for peripheral protection and a sun room with a glass roof and a larger skylight. This type of sun room is less expensive, but it is less expensive indoors in summer. Higher temperatures require sunshades.
4. If it is a sunroom that requires traditional architectural functions (such as a special living room, study room, activity room, etc.), it is advisable to choose a tempered hollow glass roof with an appropriate amount. Special insulated glass skylights are products that use broken-bridge aluminum insulated glass windows or aluminum-wood composite insulated glass windows for peripheral maintenance. They also need to be equipped with special sunshades, awnings, invisible screens and other products.
