Types of Vapour and Air Permeable Membrane


Types of Vapour and Air Permeable Membrane

A vapour and air permeable membrane (VAMP) is a material that allows vapor to pass through it but keeps moisture out. This type of membrane must be controlled carefully to ensure that vapour does not leak through it. The application of a vapour tight insulation board can help to limit moisture vapour transfer.

Vapour and air permeable membrane

Iss a self-adhering, vapour permeable membrane that bonds to almost any substrate. Its unique design allows water vapour to escape while retaining airtightness, reducing the risk of mould, mildew, condensation, timber distortion and metal corrosion. It bonds fully to the substrate with minimal sealants, making it a cost-effective choice for a wide variety of applications.

Wraptite-SA is an ideal solution for commercial projects that require a high vapour-permeability membrane. It bonds to almost any surface, including steel and concrete. It is easy to install, and offers excellent air-tightness and thermal performance. It is also suitable for use on large uninterrupted facades.

Permavent APEX

Permavent APEX is a fully-compliant vapour and air permeable membrane which allows moisture to escape through air flow. This is particularly beneficial in pitched roof structures where interstitial condensation can cause problems. It also prevents condensation from building up within the roof structure. This is an important benefit as the membrane helps prevent damage to the roof from rain.

Its installation is extremely easy and it complies with British Standards. It is available in 1m x 50m rolls and comes with all necessary fittings. It boasts a water tightness rating of w1, which makes it particularly suitable for outdoor use. The membrane is easily installed and provides a barrier to rainwater.

twrb

a brand name for building materials from Dupont, is a type of moisture and vapour permeable non-woven membrane that is water-resistant and breathable. It works by preventing liquid water from getting into wall cavities while letting water vapor escape to prevent condensation. There are several different types of breathable membrane, each with their own unique applications.

Tyvek WRB is a versatile and economical weather barrier that can be used to improve energy efficiency and comfort in commercial buildings. It is also highly durable and provides nine months of UV resistance, making it the ideal choice for many types of building applications. It is also easy to install and has a 10-year manufacturer warranty.

AIR-SHIELD SMP

The W R Meadows AIR-SHIELD SMP valor and air permeable membrane is a self-adhering, single-component membrane that exhibits excellent air and moisture transmission resistance. The material’s tough construction is nontoxic and its adhesion to substrates is excellent. The product is a great choice for frame buildings because it’s simple to install.

Before applying the AIR-SHIELD SMP, ensure that the surface is dry, smooth and clean. Using a hand roller or stiff brush, apply the membrane to the surface. When applying the membrane, make sure to overlap the upper and lower courses. The overlap should be about 2 1/2 inches (63.5 mm).

The AIR-SHIELD SMP valor and air permeable membrane offers an effective barrier against air exfiltration and condensation in masonry wall assemblies. This reduces condensation and improves the efficiency of the building’s mechanical system. In contrast, wet insulating materials lose their R-factor performance characteristics and reduce the overall energy efficiency of a structure.

Wraptite SA

Wraptite SA vapour and air-permeable membrane is a self-adhering, air-tight membrane that is ideal for commercial and residential projects. The unique blend of vapour-permeable properties and a self-adhering air barrier offers superior thermal performance and a wide service temperature range. In addition, the Wraptite SA’s bonded facer laminate resists tears and punctures, and it is highly compatible with a variety of substrates.

Wraptite SA is a self-adhesive membrane that bonds to most substrates without the need for a primer or additional sanding. Its superior permeability provides improved air quality and reduces the risk of condensation, mould and mildew. It also minimizes the risk of metal corrosion and timber distortion.
