WATERGATE PLUS
Synthetic Wall wrap.
Thermakraft Watergate Plus is specifically designed as a pliable building membrane behind exterior wall cladding. Made from synthetic materials Watergate Plus is fire retardant, water resistant and vapour permeable. The water vapour transfer rate of the product has been optimised to minimise condensation risk in homes without compromising its primary water barrier properties. Its construction allows for easier installation while maintaining performance qualities.

Product Description
Watergate Plus is a two-layer laminated pliable building membrane combining a polyester non-woven layer with a vapour permeable film. This allows water vapour to pass through from inside the wall cavity whilst water from the exterior is kept out.
The product is simply fixed to timber framing using construction staples and is made to stretch around corners providing a tight fit and reducing the risk of staple tear. It will provide temporary weather protection during construction. (Max 60 Days).
Scope of use
Watergate Plus can be used as a wall wrap on both residential and commercial buildings within the following scope:
- Class 1 and Class 10 buildings; and,
- Class 2 to Class 9 buildings subject to specific weathertightness design; and,
- Constructed with timber and steel framing in accordance with the BCA; and
- With absorbent (e.g. timber, brick or fibre cement) or non-absorbent wall claddings (e.g. metal or plastic) directly fixed to framing; or installed over an 18mm minimum drained cavity; and
- With masonry veneer in accordance with BCA; and
- Situated in non-cyclonic wind zones up to, and including N3.
- Is suitable to be used in conjunction with thermal breaks on steel framed buildings.
- Refer to BRANZ Appraisal No 729 [2017] and CodeMark Certificate CM-80003 for full details.
General
- Fire retardant.
- Unaffected by LOSP or other solvent based treated timber. However, LOSP or other solvent based treated timber must have sufficient time for the solvent to flash off in a well ventilated area. Recommended minimum 7 days.
Limitations
- Must NOT be used as a roof sarking.
- Must NOT be exposed to the weather or UV for more than 60 days.
- Watergate Plus is NOT a vapour barrier.
Compliance
When Watergate Plus wall wrap is used, installed and maintained in accordance with the statements and conditions outlined in Kingspan Insulation literatures, BRANZ appraisal and CodeMark certificate, the product will contribute to meeting the following provisions of the BCA:
- BCA Volume 1
Part F3P1 – Weatherproofing
Part F8P1 – Condensation and water vapour management
Part G5P1 – Bushfire resistance - BCA Volume 2
Part H2P2 – Weatherproofing
Part H4P7 – Condensation and water vapour management
Part H7P5 – Buildings in bushfire prone areas
Full BCA compliance details can be found in BRANZ Appraisal No. 729 [2017] and CodeMark CM-80003.
Flammability Index
Watergate Plus is less than 1mm in thickness and has an AS 1530.2:1993 Flammability index of less than 5 and therefore has a flammability index classification of low in accordance with the AS/NZS 4200.1:2017. Watergate Plus complies with NCC Clause C2D10(6)(f).
Durability
Watergate Plus is expected to have a serviceable life equal to that of the wall cladding provided:
