For a better use of uPVC as thermal insulation, you can pay attention to several points and methods:

1. Selecting windows and doors of two or more walls:
Using UPVC windows and doors with double or multi-paned glass can help reduce heat loss. The space between the layers of glass is usually filled with argon gas, which is a better insulator against heat.
2. Use insulating frames:
UPVC frames should be designed in such a way that they have the lowest amount of heat transfer. These frames must have internal insulation layers to prevent heat penetration.
3. Correct installation:
The correct installation of windows and doors is very important. Any cracks or seams can cause air infiltration and reduce the efficiency of thermal insulation. The use of sealing tapes and thermal insulators at the connection points can help improve performance.
4. Regular maintenance:
5. Use curtains and canopies:
Installing curtains or canopies on UPVC windows can help reduce radiant heat in summer and maintain heat in winter.
6. Extra insulation:
If needed, additional thermal insulation can be used in the walls and ceilings to improve the overall thermal insulation performance of the building.
Following these tips, uPVC can be used as an effective thermal insulation and help to optimize energy consumption.
