Formation causes
Thermal bridge effect, that is, the physical effect of heat conduction, due to the floor and the corner of the wall with concrete ring beams and structural columns, generally due to the failure to deal with heat conduction and caused. We used in the construction of the concrete material has a good thermal conductivity at the same time due to poor indoor ventilation, late fall and early winter indoor and outdoor temperature difference is large, hot and cold air frequent contact, uneven thermal conductivity of the wall insulation layer, resulting in thermal bridging effect, so that we will be indoor walls will be condensation, mold and even water dripping.
In addition, such as windows and doors (gap treatment), structural beams, dark columns (dense reinforcement) and other parts of the winter is not heat preservation, summer is not insulated, is not conducive to energy conservation and thermal insulation of the building, energy consumption, the need for these parts of the special treatment, in order to achieve energy saving and emission reduction, to avoid generating the "thermal bridge effect".
Thermal Conductivity Path
When there are materials with high thermal conductivity such as metal (e.g. unbroken aluminum alloy), concrete, etc. in the wall or door/window frames, the heat will be transferred quickly through these materials to form "thermal bridges", which will damage the overall thermal insulation effect.
Energy Loss
Winter: indoor heat is lost to the outside through thermal bridges; Summer: external high temperature is transferred to the inside through thermal bridges, increasing the air conditioning load.
Risk of condensation
The temperature of the thermal bridge is lower than that of the surrounding area, which is prone to condensation and mold growth, affecting the durability and health of the building.
Solution: Thermal Break Technology
Heat insulating strip
Adding PA66 nylon heat insulating strip in the middle of the aluminum profile physically separates the inner and outer aluminum profiles, blocking the heat transfer.
Multi-cavity structure
Increase the number of chambers in the profile and utilize the air layer to reduce heat transfer.
Sealing system
Combined with EPDM adhesive tape (EPDM) to reduce air infiltration and improve the overall airtightness.
