Typar® HouseWrap

Typar® HouseWrap is the foundation for the Weather Protection System. A nonwoven composite fabric, it provides the perfect balance of water/air holdout and moisture vapour transmission (MVT). It reduces the chance of exterior water and air from entering the wall cavity while allowing moisture vapor from inside the home to escape the wall cavity.



Typar® HouseWrap delivers four key advantages you won't find with other housewraps:

  • Superior water holdout - blocks water from entering the wall cavity.
  • Exceptional moisture vapor transmission (MVT) - it breathes so moisture can escape the wall cavity.
  • Superior tear strength - proven to withstand heavy winds and is almost five times stronger than the leading competitive wrap.
  • Optimal surfactant and UV resistance - reduces the damaging effects that oils and tannins from cedar siding, cement siding, stucco, brick and soaps from powerwashing can have on the system's ability to block bulk moisture penetration; stands up to the beating sun on the jobsite for up to 6 months without degradation.

  • Typar® VS. Building Paper: Faster, Drier, more Energy Efficient
    • Faster Installation — Only 1 layer of Typar® is required vs. 2 layers of 30-min building paper (One 9-foot tall roll of Typar® versus two layers of 3-foot tall rolls of building paper = 6 wraps of paper to 1 wrap of Typar®!)
    • Industry-Leading Liquid Water Holdout versus very little liquid water protection for building paper
    • Typar® has a reliable moisture vapour permeance for ideal "breathing" of coastal buildings
    • Added Moisture Intrusion Protection due to fewer laps and penetrations
    • Better energy efficiency as Typar® is an air barrier and has fewer "laps" and penetrations than paper

    Typar vs. Tyvek

    While we believe that good-performing housewraps generally protect our buildings better than paper, our housewraps Typar® Housewrap™ and Typar® Metrowrap™ both vastly outperform the leading building wrap.

    Although the market-price of our standard Typar® Housewrap™ is closer to the price of Tyvek® Homewrap™, many of the performance characteristics of Typar® Housewrap™ far exceed those of Tyvek® CommercialWrap™. In other words, Typar® Housewrap™ outperforms both Tyvek® HomeWrap™ and Tyvek® CommercialWrap™. Typar® Metrowrap™ goes above and beyond for additional U.V. and water holdout protection.

    Although Tyvek®'s products are typically promoted for their higher permeance than some competitors, many experts today agree that for our climate, a vapour permeance in the range of 10 - 20 perms is ideal.
