Robust Line of Underlayments Protect Every Part of a Home

By GCP Applied Technologies.

From the walls to the roof, GCP offers complete protection.

In a complete home protection system, all areas of the home must be covered. This includes the outer walls and the roof of a house. GCP’s continuous system of underlayments offer complete home protection for a variety of homes. GRACE ICE & WATER SHIELD® and GRACE ICE & WATER SHIELD® HT are built for high-temperature applications and when coupled with the VYCOR® house wrap system, you can have peace of mind knowing everything in your home has coverage. 

VYCOR® weather barrier and flashing tapes 

VYCOR® enV-S™ self-adhered weather barrier 

VYCOR® enV-S™ self-adhered weather barrier represents the next generation in house wrap and is designed to provide superior weather protection, and improved energy performance. The membrane brings together the weather protection benefits of a self-adhered membrane, with the breathability of traditional house wraps. The unique adhesive coating bonds strongly to the sheathing, but remains vapor permeable. VYCOR® enV-S™ membrane resists damage in windy conditions, leading to less rework and a high-quality appearance. 

VYCOR® PRO flashing tape 

VYCOR® PRO flashing, with its unique film and non-asphaltic, butyl-modified adhesive technology, provides premium protection against water infiltration in all critical non-roof detail areas, that traditional building papers, felts, house wraps and other flashing products cannot match. 

VYCOR® Plus flashing tape 

VYCOR® Plus self-adhered flashing is composed of durable, cross-laminated, high-density polyethylene sheet, backed by an aggressive, pressure-sensitive rubberized asphalt adhesive. 

GRACE ICE & WATER SHIELD® HT high-temp roofing underlayment 

GRACE ICE & WATER SHIELD® HT high temperature self-adhered roofing underlayment is a premier membrane designed to deliver premium in-place performance for high temperature applications. It is composed of two waterproofing materials—an innovative and proprietary rubberized asphalt adhesive combined with a high-performance polymeric film with UV barrier properties. The rubberized asphalt surface is backed with a foldless release paper that protects its adhesive quality. During application, the release paper is easily removed, allowing the rubberized asphalt to bond tightly to the roof deck. The RIPCORD® embedded in the adhesive provides the applicator a “split release on demand” feature, making it easier to apply in detail areas. 

GRACE ICE & WATER SHIELD original, self-adhered roofing underlayment 

GRACE ICE & WATER SHIELD® self-adhered roofing underlayment has protected millions of homes' roofs, and been installed on marquee projects in 25 countries, since its introduction in 1978. This high-performance solution provides superior performance at an excellent value. GRACE ICE & WATER SHIELD® outperforms the competition by letting contractors shine, and by keeping families safe and dry. 

GRACE ULTRA® underlayment for metal roofs 

GRACE ULTRA™ butyl roofing underlayment is composed of two waterproofing materials—an aggressive 100% butyl rubber adhesive backed by a layer of high density cross laminated polyethylene film. The product is 30 mils (0.76 mm) thick making it easy to handle and apply. The unique, advanced adhesive formulation offers premium adhesion to the roof deck, high quality laps, superior seal around roofing fasteners, and unrivaled high temperature stability. The adhesive is backed by a protective plastic release liner that protects its adhesive quality. The release liner is easily removed allowing the adhesive to be bonded tightly to the roof deck.
