Vapor barriers

Waterproof sheet that allows to control the passage of vapour through the roof, avoiding condensation. It must be placed below the thermal insulation.

Polyethylene vapor barrier with polypropylene backing and aluminum layer. Blocks vapor diffusion into the insulation layer and is heat-reflective. Use Roof underlay for boarding and concrete. Composition Aluminum/polyethylene vapor ...

Isola Dobbelt Lag is a double-layer roof covering consisting of SBS polymer bitumen, with the upper layer welded to the underlay. These systems consist of Isola Kraftunderlag (strong underlay) and Isola Sveiseoverlag (welded upper layer). Laying Isola ...

A moisture-variable vapour barrier for use in the air-tight layer. The functional membrane changes its diffusion resistance depending on the current humidity. During the winter months room atmosphere is generally dryer. The sd-value of ...

Three-layer vapour-permeable roof membrane. Made of two layers of polypropylene nonwoven and functional film which ensures high vapour-permeability and water-tightness of the underlay. Extreme resistance to tearing makes it the membrane ...

Intelligent vapour check and airtight membrane. The principle raw material used to produce pro clima DB + is recycled paper which is strengthened with a reinforcement layer. DB+ is an environmentally friendly option for the sustainable ...

Vapour barrier made of PE Type Color: blue Packaging 1 roll à 100 m2 55 rolls/pallet very good blocking function very good bondable efficient processing roll width: 4.00 m roll length: 25 m grammage: approx. 152 ...

A 40 Mil composite consisting of 35 Mils of self-adhering rubberized asphalt laminated to a 5 Mil woven polypropylene film. A siliconized one-piece release liner prevents the material from bonding to itself in the roll and is easily removed ...

High Adhesive Total Vapour Barrier Butyl Membrane for Cryogenic Applications Bu-tylene DS Crio 12/25/12 is a self-adhesive waterproofing and sealing heavy duty vapour barrier membrane. Bu-tylene DS Crio 12/25/12 is made of a high adhesive ...

Viper® VaporCheck® is designed to help builders control vapor and moisture infiltration in homes and buildings. The cross-woven polyethylene vapor barrier is engineered with superior puncture resistance and tensile strength.

The plain answer to the question of how to keep a roof build-up permanently dry is to install a vapour control layer. We offer two different kinds: vapour control sheets with a low vapour barrier coefficient such as PE foil, or "practically ...

VAPORBLOCK® PLUS™ Series consist of seven-layer co-extruded barriers made from state-of-the-art polyethylene and EVOH resins to provide unmatched impact strength as well as superior resistance to gas and moisture transmission. VaporBlock ...

DERBICOAT ALU is composed of a blend made of a specific bitumen modified by noble polymers (high-grade APP also called TPO). An aluminium sheet, centered in the membrane, makes it a high performance vapour barrier.

Majrex® 200 For even more security in wall/roof structures on the room side of thermal insulation, this vapour control layer with Hygrobrid technology helps especially in cases of problematical building physics. Hygrobrid increased ...

SCUDOTENE V consists of elastomeric waterproofing membranes obtained from distilled bitumen modified with SBS elastomeric polymers and special tackifiers, offering a high adhesive power. The reinforcement is a glass fibre mat. The adhesion ...
