Upgrading your old windows/doors to UPVC or incorporating UPVC windows/doors into new builds have huge advantages with regards to energy savings. The insulation quality of UPVC is significant over aluminum. UPVC is more than 1200 times less conductive than aluminum and so avoids heat transfer through the the frames. In particular this is an issue where any outer frame comes into contact with direct sunlight.
The majority of aluminum door and window systems in Thailand do not incorporate any thermal break and this leads to the frame absorbing the outside heat only to radiate and disperse the heat internally. This can add a significant amount of extra heat into the internal spaces of a room. To counteract this your air-conditioning is required to work much harder and will use much more energy in order to cool the room to a more comfortable temperature.
In Thailand, air-conditioning accounts for the majority of the energy cost expended within most buildings throughout the country. Another source of temperature transfer is through the glass. The glass normally covers a large surface area and is a good conductor of temperature. This means that a large percentage of the efforts of your air-conditioning system can be lost via temperature transfer through the glass. In order to reduce the effect we recommend installing double insulated glass.
This system traps a layer of air insulating the inner pane from the outer and drastically reducing temperature transfer. Installing UPVC doors and windows, together with our double insulated glass option can equate up to 40% saving off of your cooling energy costs.
