Weather Protection Systems


Weather Resistant Barriers

How can you build a home that provides excellent comfort and energy-efficiency while controlling the damaging impact of moisture intrusion? The TYPAR Weather Protection System. It provides exceptional air and water holdout, optimal moisture vapor transmission, superior tear strength and outstanding surfactant resistance PLUS The TYPAR Advantage.

At the heart of the system are TYPAR® Weather-Resistant Barriers (WRB) which act as air and moisture barriers, while allowing moisture vapor to escape from the wall cavity. Installed before the exterior siding, TYPAR WRBs also protect the structure from nature’s harshest elements with exceptional tear strength and ultraviolet stability.

  • Exceptional moisture vapour transmission
  • Superior tear strength
  • UV resistant
  • Optimal surfactant
  • Superior water holdout


TYPAR HouseWrap eliminates drafts in the wall, which helps reduce energy costs. And the TYPAR material itself will not support the growth of mold or disintegrate over time.

Features & Benefits

  • 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 power washing can have. Stands up to the beating sun on the jobsite for up to 6 months without degradation.

Protecting your roof deck from moisture is key to assuring the lifespan of the roof and the long-term durability of the home.

Whether your roof is covered with shingles, shakes, tile, slate or metal, be sure it’s protected with SURROUND SR Underlayment. A smart alternative to felt, it is water’s toughest opponent, creating a secondary water barrier that reduces the incidence of leaks caused by storm damage, wind-driven rain, ice dams and worn roofing materials. It is a waterproof, synthetic polymer material that will protect your homes against moisture intrusion.

Features & Benefits

  • Stronger – 10 times stronger than 30# felt for the ultimate tear resistance, so it will not blow off during installation and helps eliminate the need for costly roof repair.
  • Drier – the unique slip-resistant surface is waterproof to prevent moisture issues.
  • Lighter – up to 10 times lighter than 30# felt so it’s easy to carry onto a roof.
  • Faster – in addition to having five times more underlayment per roll than felt, the rolls are also 25 percent wider for quicker roof deck coverage.
  • Secure – SURROUND SR Underlayment meets the more stringent requirements of ICC AC48-Acceptance Criteria for Roof Underlayment for Use in Severe Climate Areas.
