系統特點
1.葉片采用鋁合金材質,美觀、大氣、還具有很強的防腐蝕功能。
2.葉片兩側獨特排水槽,在遮陽、通風、采光的同時,還能有效防雨防風。
3.***防暴風雨 英國建筑服務研究與信息協會(BSRIA)質量認證
4.適合特殊無電源環境。
5.百葉顏色可根據客戶的要求而定。
6.有單層、雙層、三層多種類型可選。
 
The principal objective of Ventilation (or Performance) Louvre systems is to allow the passage of air, whilst providing a measure of protection against the rain.
Specifying performance has not been helped by conflicting technical information given by louvre manufacturers which quotes percentage free areas measured in different ways, namely as resistance to airflow and aerodynamic coefficients alternatively.
Design considerations include:
1.Site location and exposure
2.Severity of local (site) weather conditions
3.Location and exposure of louvres on building
4.Airflow rate and direction through louvre
5.Maximum acceptable pressure drop
6.Degree and depth of water penetration acceptable
7.Special solutions for sloping applications
8.Single bank,Double bank,Triple bank for optional.
For a true comparison of performance, the aerodynamic coefficient and the degree of rain defence effectiveness are the only sensible measures ,Approved by BSRIA UK。
