Product design --the winter cold against the skylight

In order to resist the long winter, the excellent thermal insulation performance of the smoke and heat exhaust skylight plays a key role. Then what are the details related to the thermal insulation properties of the building smoke exhaust skylight system?

We know that a quarter of the energy used for heating in winter or cooling in summer through air conditioning is lost through cracks in doors and Windows.  Improving the airtight performance of doors and Windows is the key to energy saving.  The airtight performance of door and window refers to the air permeability on the length of opening seam of door and window unit or unit area.  It measures the ability of doors and Windows to prevent air penetration when they are closed.  The height of airtight performance of door and window, the loss of heat is greatly affected, airtight performance is better, heat exchange is less, the influence to room temperature is smaller too.

"GBT 7106-2008 building doors and Windows airtight, watertight, wind resistance performance classification and detection method" is divided into 8 grades, the higher the level of the lower the amount of permeability, the higher the level of the better.  Air tightness of TOPRISE smoke exhaust skylight: GB/T7106-2008 Grade 8.  TOPRISE smoke exhaust skylight can prevent indoor heating loss in winter, maintain indoor temperature, and in summer can reduce the impact of outdoor high temperature on indoor, so as to form the effect of warm in winter and cool in summer, and effectively reduce energy consumption, energy conservation and environmental protection.

In cold winter, it is very important to have excellent insulation performance of smoke exhaust skylight, which can also be reflected in the value of heat transfer coefficient. Heat transfer coefficient refers to the heat that passes through doors and Windows or glass curtain wall per unit area in unit time when the temperature difference between inside and outside the closed doors and Windows is 1K (℃). This index shows the ability of doors and Windows to prevent heat loss, and the lower the value, the better the insulation performance of doors and Windows. Heat transfer coefficient K value of TOPRISE broken bridge profile smoke exhaust skylight is lower than 2.2W/(㎡.k), effectively reduce heat conduction, cut off the cold bridge, ensure the heat preservation and insulation effect of smoke exhaust skylight, truly achieve energy saving and environmental protection, reduce energy consumption expenditure.

TOPRISE Skylight frame aluminum alloy material, middle-east multi-cavity structure design, can effectively block the heat conduction pathways, in order to better partition (including voice) heat transfer in order to achieve the purpose of heat preservation and heat insulation, blocking the cold bridge, and reduce the loss of indoor air conditioning and heating loss, eventually achieve the effects of saving energy and reducing consumption.

In the sealing structure design of the smoke exhaust skylight, TOPRISE adopts the "automobile grade" EPDM sealing strip, which has strong anti-aging and better softness, and can prevent the loss of indoor heating in winter and keep the indoor temperature.  And summer can reduce the impact of outdoor high temperature on indoor, so as to form the effect of warm winter and cool summer, and effectively reduce energy consumption, energy conservation and environmental protection.  The flexible connection between the sun plate and the window frame achieves a more reliable sealing effect, while ensuring the infiltration of wind and rain "no chance".

The lighting materials of smoke and heat exhaust skylight account for about 65-75% of the overall area, or even higher, so the effect of lighting materials on the thermal insulation performance of the whole window is more and more important.  Nowadays, the lighting materials of smoke exhaust skylights have gradually developed from traditional lighting, wind protection, rain protection and other traditional properties to heat insulation, heat preservation, safety, noise prevention, decoration and other composite properties, so as to enhance the sealing, energy saving and heat preservation effect of the whole building.
