Air Tight Membrane – Vapour Control Layer – Intello Plus Vapour Check Barrier 75m2

Product Description

Intello Plus Vapour Check Barrier gives maximum protection to thermal insulation where leaks may have occurred. This applies to insulating materials in all constructions including pitched roofs, flat roofs and walls. Intello Plus is an intelligent hydrosafe airtight vapour control membrane that reacts to humidity. It allows up to 100 times more moisture vapour to pass through when humidity is high to provide industry leading protection from moisture related structural damage. You can use it on internal walls, floors and ceilings.

Pro Clima Intello Plus key features:

• Provides optimum protection for all thermal insulation systems in roofs, ceiling, walls and floors.
• Offers high diffusion tightness in winter and maximum diffusion openness in summer.
• In winter, its high diffusion resistance provides ideal protection for the building’s structure against condensation.
• In summer, its low diffusion resistance facilitates rapid drying.
• It is translucent, easy to install, fully recyclable.
• It offers the ideal solution to structures that are difficult to protect against condensation e.g. flat roofs, flexible metal sheeting, etc.
• Intello Plus provides lasting protection against mould growth, thereby protecting the health of the occupants and ensuring structural durability.
• Meets with the durability requirements of EN 13984.
• Has a very high nail tear resistance due to reinforcing layer
• Membrane Material: polyethylene copolymer
• Fleece and reinforcement layer: polypropylene
• Vapour Resistance: (humidity variable): 1.25 MNs/g – 125 MNs/g
• Fire Rating: E
• Temperature Resistance: -40° C to 80° C
• 3rd Party Accreditation: NSAI CE
• Colour: White
• 1.5M x 50 Metres | 75m²

Overview:
Pro Clima Intello Plus is classified as airtight and also features a humidity variable vapour transfer rate. When conditions are right, the higher the humidity within construction, the more vapour passes through. It is used to airtight seal interior walls and ceilings, it allows moisture in the air, within the insulation of the building fabric to escape through its unique Intelligent membrane. Intello Plus also improves indoor air quality by eliminating the risk of condensation, mould and other moisture related problems.

Where to use it:
Intello Plus vapour control membrane can be used internally on walls and ceilings in timber frame buildings or in the timber roof of masonry buildings. It is especially suited to lightweight constructions where fibrous or flexible insulation is used in the walls and ceilings.

When retrofitting airtightness to an existing building, Intello Plus can be used in the roof and ceilings.

What it does:
Pro Clima Intello Plus, as a hydrosafe airtight intelligent vapour control membrane, differs from other more conventional membranes by having the ability to alter its diffusion resistance based on the current humidity of its surroundings. This ensures the risk of condensation is minimised, with no structural damage from moisture, mould, rot and dampness.

How it works:
The construction phase often generates high humidity as wet building materials like concrete, plaster or screeds dry out or if materials stored on-site were not adequately protected from rain. In this situation, Intello Plus reacts to allow up to 100x more moisture to escape so the building can dry out far quicker than if a membrane with a fixed diffusion resistance was used. When moisture levels and humidity in the building are high, either from the construction, leaks caused by unintentional punctures in the membrane or by moisture transfer from adjoining structures (flanking), the risk of condensation and structural damage is greater; Intello Plus is the best choice to eliminate this risk and safeguard the structure for the entire lifetime of the building.

Why it is so popular:
Intello Plus has three layers; a fleecy backing that reduces friction, so snags and tears are less likely to cause a hole and compromise the airtightness. The backing also makes the membrane easier to install by improving its mobility when sliding over surfaces. The middle layer is the airtight intelligent membrane and the third layer is a super strong mesh that greatly increases the tensile strength and nail/staple tear resistance. This reinforcement makes Intello Plus perfectly suitable for any type of blown-in (dense-pack) insulation due to it having a very low amount of stretch.

The quality and effectiveness of Intello Plus have been independently tested, verified and approved by leading certification bodies. These include The British Board of Agreement (BBA), Passive House Institute (with the best ever results), The National Standards Authority of Ireland (NSAI) and others.

Pro Clima Intello Plus has now received European Technical Approval (ETA) and is the 1st Intelligent airtightness membrane that has proven its durability in accordance with EN Norms. Based on independent accelerated ageing tests, Intello Plus has a life expectancy of at least 50 years; no other Intelligent membrane has attained this level of performance to date.

System warranty:
Pro Clima provides a limited system warranty, backed-up with public liability insurance, for all airtightness system, roof and wall sealing system and construction products that they supply. A 10-year warranty is provided for these products when correctly installed in combination with approved thermal insulation materials and other Pro Clima system products. When correctly installed in combination with other manufacturers’ products (not made by Pro Clima), a 6-year warranty is provided.

Features:

• Industry leading membrane since 2004.
• Airtight and adaptive vapour resistant or vapour open membrane when required.
• Intelligent Membrane that reacts to humidity.
• Pro Clima Hydrosafe®ï¸ Technology.
• BBA & NSAI Certified.
• Passivhaus Certified.
• First intelligent membrane with ETA approval.
• Reinforced Membrane.

Benefits

• A comfortable construction is achieved, eliminating draughts and maximising the performance of the insulation.
• By changing its vapour transfer rate based on the humidity level, no damaging build-up of moisture occurs at the membrane. A moisture build-up is often seen as “sweating” on polythene (non-breathable) vapour control membranes.
• Hydrosafe®ï¸protects against moisture related structural damage and against higher humidity and wet materials at the construction phase.
• Proven history of success since 2004. Also highly regarded and quality approved by leading certification bodies.
• Proven durability with a life expectancy of at least 50 years.
• Robust and tear resistant, it is suitable for use with blown-in insulation.
• Approved and recommended by the Passivhaus Institute for use in Passive houses.
