FlatWrap^® HP Housewrap

​

FlatWrap® HP is a high-performance water-resistant barrier. It can be used alone in some climates as a simple moisture management solution. However, it is most effective for superior bulk water drainage and exceptional vapor when used in conjunction with a rainscreen. 

As a tri-laminate house wrap, FlatWrap® HP has a micro-porous, non-perforated film that is put in between two non-woven layers. The film layer gives the product breathability and water hold-out capabilities for reliable moisture management. The non-woven layers give it extra durability to protect the film from damage during the housewrap installation process. 

FlatWrap® HP is a perfect WRB to use behind our line of Slicker® rainscreen products. It can also be paired with HydroGap® Drainable housewrap as the required secondary layer in stone or stucco applications. This product is not intended for open joint applications with intentional gaps left between siding boards (check out InvisiWrap UV for these applications).
