Non-standard doors are the weakest link in heat insulation, heat preservation, sound insulation and safety in the entire building envelope. So how to improve its heat-proof effect? Reasonably select the original glass to control the radiation heat transfer through the non-standard door.

Glass type: When choosing the original glass, different glass should be selected according to different regions.

LOW-E glass film surface position: Due to the low radiation characteristics of the low-emissivity coated glass film surface, when it is used to form an insulating glass, the difference in the placement of the film surface will affect the energy-saving characteristics of the insulating glass. The selection of window frame materials with good thermal insulation performance and non-standard door materials are the weak link in the insulation of the entire non-standard door system. About 1/4 of the entire window is made of window frame materials. Improve the airtight performance of the whole window. The airtight performance of non-standard doors in buildings refers to the ability of a closed building exterior window to prevent air from infiltrating into the room under the action of outdoor pressure difference. Improve the performance of the gas in the insulating glass spacer layer In foreign countries, inert gas such as argon is generally used to fill the insulating glass cavity to produce insulating glass with better energy-saving effect.

The use of low-conductivity spacers The use of warm-edge spacers is a method that can improve the thermal conductivity of the edge of the insulating glass. Appropriately increasing the thickness of the spacer layer has a great influence on the energy-saving effect of insulating glass.

Of course, these measures still have shortcomings, but it is undeniable that it has improved the thermal insulation effect of non-standard doors to a large extent.
