CLAF® mesh and film housewrap for one of the strongest and highest permeability housewraps currently on the market.

The JX ALTA™ HP residential housewrap has a higher permeability rating than any other housewrap currently available - with better tear resistance than the industry standard.

Translucent, drainage-equipped and stronger than standard high-perm housewraps, the JX ALTA™ HP residential housewrap product is the one builders and contractors turn to when high breathability is required in a wall structure.

Every roll of JX ALTA™ HP is made with unique CLAF® mesh and film materials. This CLAF® mesh increases the tear resistance of every roll, and creates a geometric, multi-directional drainage plane within housewraps. The mesh material in our HP product keeps each roll of housewrap strong.

testimonial quote

As a builder of residential and commercial buildings in Charleston, SC, we are faced with seasonal rains, high temperatures, high humidity and heavy air conditioning use during the long summer months...  When we stick frame a new house in the Low Country  we look for several features in our Moisture Barrier...  With the unique vertical diamond surface of the Alta Drainable house wrap, the moisture behind the siding is allowed to drain and dissipate providing a more breathable construction. The Alta product is one more element in our battle against the elements and is our house wrap of choice.
