PROCTOR Wraptite Self-adhesive Vapour Permeable Airtight Membrane - 1.5 x 50m

Proctor Wraptite combines important properties of vapour permeability and airtightness in one affordable self-adhering membrane. It fully bonds to virtually any substrate, with a key benefit being its ease of installation, negating the requirement for sealants or tapes. It makes a significant contribution to a building’s thermal performance by preventing lateral air movement, but it also contributes to a healthy living environment and a healthy building thanks to its vapour permeability. With an Sd of 0.039m, it provides a high degree of vapour permeability in a commercial-quality, self-adhered, airtight breathable membrane.

PROCTOR Wraptite UV Self-adhesive UV Vapour Permeable Airtight Membrane - 1.5 x 50m

Proctor Wraptite UV is a Class B fire-rated membrane that combines the best properties of vapour permeability and air tightness in one innovative, self-adhering product, which is specifically designed for use behind open jointed cladding. Wraptite UV has exceptional water resistance and UV resistance to provide a “shadow” appearance within open rainscreen façades. Manufactured from polyester and a functional coating, with a proprietary acrylic moisture vapour permeable adhesive and silicone-coated PET release liner. Wraptite UV bonds (no mechanical attachment) to multiple substrates for air tightness and ease of installation, negating the requirement for a primer, sealants or tapes. The product provides an initial grab with a full curing time of approximately 6 hours depending on environmental conditions. Wraptite UV prevents lateral air movement enhancing the buildings thermal performance. With a rating of Sd 0.06m, it provides a high vapour permeability in a commercial quality, self-adhered, airtight breathable membrane. To protect the membrane from mechanical damage, the joint openings in the façade covering have to be less than 40% of the area, and a maximum of 50mm wide. Whilst for use behind open jointed cladding, the membrane is specifically designed for those who require protection against water ingress for extended periods of time, in a range of applications, including the storage and transportation of volumetric modules, offsite panelised systems and/or within high rise façade construction. Wraptite UV would also provide a shadow gap detail behind window flashing details, or in open jointed façade systems in offsite construction, rainscreen and timber cladding systems.

Kingspan

Kingspan Nilvent Breather Membrane - 1.5m x 50m

Kingspan Nilvent is a breathable membrane suitable for use in unventilated pitched roof and timber frame wall applications. The membrane is waterproof, non-tenting and airtight at normal building pressures. Certification:BBA certified

SOUDAL

SOUDAL Soudatight LQ Paint On Airtight Membrane 4.5kg

Soudal Soudatight LQ is a high-quality fibre-reinforced polymer membrane which forms an air and vapour-tight elastic membrane after drying. The product can be quickly and easily applied with a brush in the desired layer thickness on almost any mineral substrate. Fills cracks up to 5 mm due to fibre-reinforcement. Once dried a second coat (or more) can be applied if required, after which it can be painted or plastered over. The black variation changes colour after drying, from blue to black. The white version does not have this colour indication.  

Thermafleece

Thermafleece Breather Membrane

Thermafleece Breather Membrane is a lightweight vapour permeable underlay designed for use in floors and walls or on top of insulation as a protective layer. It comprises of 3 layers; two outer layers composed of a non-woven polypropylene and an inner breathable microporous film. Thermafleece Breather Membrane is ideal for supporting insulation between suspended floor joists or as a protective layer above insulation installed between floor joists to prevent the accumulation of debris on top of the insulation. The membrane can be nailed or stapled to the underside of the floor joist if access permits. Alternatively, the membrane can be installed from above the rafter.
