IZOPERM Plus can be used as an inner airtight membrane and vapour control layer for externally vapour open build-ups. It can be used in roofs, walls, floors and ceilings in residential and commercial applications.
IZOPERM plus is a vapour check with an Sd value of 5 (US Perm of 0.69). This provides optimal vapour control for most constructions. IZOPERM Plus is reinforced, flexible, compatible with all insulation types and does not shrink.
IZOPERM Plus should be installed with the printed side facing the installer in a taught manner with all creases, seams, overlaps, joints and penetrations completely sealed. It should be installed so that all overlaps are sealed by taping to the printed side, and can be installed parallel or perpendicular to the supporting structure with maximum distances between supports of 1000mm (40”).
If installation is perpendicular to the supporting structures a batten is required or additional taping at 500mm strips perpendicular to overlap joints at 300mm (12”) intervals. IZOPERM Plus must overlap by 100mm (4”) and perpendicular battens should be installed to support the weight of insulation and to protect the product from future damage.
Staple in a triangular pattern to ensure the membrane is taught but make sure membrane is relaxed at junctions to allow for movement. Staple at 75mm (3”) intervals for blown in insulation or 300mm (12”) generally. Staples should be 10 mm (0.4″) wide and 8 mm (0.31″) long. Partel CONDUO can be used as an installation aid where staples cannot be used, Overlaps can then be sealed with VARASEAL, CONIZO, or CONEXO. Penetrations should be sealed using KABSEAL or BUTAFLEX and edge connections can be sealed with ACRABOND, ACRALINE or Partel tapes.
In cold climates blown in insulation should be installed as soon as IZOPERM Plus installation is complete and for loose fitted installation IZOPERM Plus should be fitted immediately after installation. Installation of vapour control layers in cold temperatures should make allowance for necessary heating, ventilation as adhesives and primers are water based, and adhesives will not adhere to wet surfaces. In high humidity situations >70% and cold temperatures visible water could be seen on the internal surface of IZOPERM Plus which prevents functionality.
Connection joints should be free from tensile strain. Acrylic base adhesive tapes are pressure activated, sufficient pressure is required to ensure a long lasting bond. A smoother physical substrate will result in optimum adhesion between tape and surface. It is the responsibility of the applicator to check the substrate for suitability, adhesion tests are recommended in non standard situations. Use Acraprime to prime all rough, porous or dusty surfaces.
