Intello Plus
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 a construction, the more vapour passes through. 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.

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 a construction, the more vapour passes through. 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.
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.
Fixing the Membranes
- Intello Plus should be installed with the printed side facing the installer. Each length of membrane should be placed at right angles to studs or rafters without sagging. There must be no creases or folds in the membrane.
- When installed horizontally on rafters, the gap between each rafter must not be more than 100cm. To support the weight of insulation exerting pressure on the Intello Plus, laths should be installed no more than 50cm apart.
- Use galvanised staples that are at least 10mm wide and 8mm long to attach the membrane. Staple every 10 to 15cm and overlap lengths of membrane by least 10cm.
Preparation
- Surfaces should be brushed down before bonding. Dust should be vacuum cleaned or wiped with a cloth.
- All surfaces must be suitable for permanent, airtight adhesion with airtightness tape and joint adhesive, and must be stable, dry, smooth and free of dust, silicone and grease.
- Adhesion to frozen surfaces is not possible. When it comes to protecting the structure, the best results can be achieved with high-quality vapour checks and airtightness membranes and timber derived sheathing. In case of doubt, adhesion tests should be carried out.
Overlap the Membrane
- Once the first membrane is in place the second layer is fitted. The membrane may overlap by about 10cm. The printed markings are an aid to orientation.
Sealing the membrane
-
Once the vapour check is fitted it has to be sealed. The membranes should be sealed at overlaps without strain or loading, using Tescon Vana or Tescon No 1 adhesive tape. Creases in the overlap area must not be over-taped; they must be cut off and re-sealed. The tape should be applied centrally and pressed down firmly using, for example pro clima PRESSFIX.
- For connections to insulated, double-layer chimneys, apply approximately 3cm of INTELLO to the chimney.
- Apply an approximately 5mm thick adhesive bead (more if necessary) with Orcon F and lay the membrane, with an expansion joint, in the adhesive bed.
- Do not press the adhesive completely flat.Seal the corners with short pieces of Tescon Vana or Tescon No.1 In the centre of the adhesive tape, cut halfway through. Then it is easy to shape.
Pipe and Cable Sealing
- If pipes or cables penetrate the airtightness layer they too must be securely sealed. The most suitable means of doing this is with airtightness grommets made from EDPM. This flexible material allows a tight fit, and Kaflex is available in all common diameters. Cable grommets are self-adhesive.
- Remove the release paper, push over the cable and stick on.
- Roflex pipe grommets are affixed using Tescon Vana. Press firmly to secure the adhesive tape.
Corner Sealing
- The airtightness of angled joints is also important.
- Sealing is simplified with the corner adhesive tape Tescon Profil. It features three release paper strips.
- This allows you to “activate” a single part of the adhesive surface and to seal corners junction by junction.Contega Solido SL also creates an interior airtight and vapour-retarding seal of angled joints to adjacent components such as joist ends to mineral sub-surfaces like concrete and sand-lime brick, providing the surface has been primed with Tescon Primer RP.
- This tapes can be plastered over.
Completion
- Cross- battens with a maximum spacing of 50 cm should hold the weight of the insulation.
- An interior lining protects the membranes from damage and UV light.
- Once all the joints have been sealed, it is advisable to check the airtightness using a Blower Door.
Suitable For
- 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.
Coverage Rate
- 1.5m x 20m - 30m2
- 1.5m x 50m - 75m2
- 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®️ Technology
- BBA & NSAI Certified
- Passivhaus Certified
- First intelligent membrane with ETA approval
- Reinforced Membrane
- A comfortable construction is achieved, eliminating draughts and maximising the performance of the insulation.
- By changing its vapour transfer rate based on 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®️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.
