Many people will be confused about whether thermal break aluminium windows and doors or non-thermal break aluminium windows and doors are better, that must be thermal break profile. This thermal break aluminium has good sound insulation, heat insulation and energy saving! Especially on the street, who does not want to sleep quietly on the weekend without being disturbed.
However, many people understand thermal break aluminum aluminum in this step. What kind of windows and doors is broken aluminum? Why it has good sound insulation and heat preservation and energy saving, let me give you a good introduction.
- What is thermal break aluminium door and window
The bridge in the name of new bridge aluminum refers to the hot and cold bridge in the material science sense, and the word break indicates the action, i.e. thermal break aluminum. Specifically, because aluminum alloy is a kind of metal with fast thermal conductivity when the temperature difference between indoor and outdoor is large, aluminum alloy can become a heat transfer bridge. This material is made into windows and doors with poor thermal insulation. thermal break aluminium breaks the aluminum alloy from the middle. It uses hard plastic to connect the broken aluminum alloy. We know that the thermal conductivity of plastic is significantly slower than metal, so heat does not easily pass through the whole material, and the thermal insulation performance of the material will be improved. This is the origin of the name of thermal break aluminium (alloy). - Thermal break aluminium windows and doors why sound and heat insulation is good?
This thermally broken aluminum, although the bridge is broken, but is still aluminum ah! Some people may be: why aluminum windows and doors heat insulation? Shouldn’t aluminum windows and doors be heat-conducting? In fact, aluminum windows and doors have unique insulation strips of aluminum windows and doors. Windows and doors mainly rely on these strips to maintain the temperature difference between indoor and outdoor. If a window or door company wants to use a good insulation strip, that strip must have high strength flexibility and very low heat and cold conduction properties.
The main insulation strips on the market are mainly made of advanced nylon material, and the other is made of ordinary PVC material. Each of these two materials has its advantages. Insulation strips made of advanced nylon material have high melting points and good heating and self-extinguishing properties. And the effect of insulation strips made of PVC material is not as good as nylon material obviously PVC. PVC it is an acronym for a chemical quality called polyvinyl chloride. The main material of poly compound B insulation strip is 25% calcium carbonate and polyvinyl chloride resin powder. The heat insulation effect of doors and windows made of PVC material is far less effective than that of nylon.
