* Note: specifiers and product user must confirm roof and wall cladding system compatibility with the underlay before installation.
Thermabar 344 is intended for use in commercial and industrial buildings that are subject to specific engineering design. These buildings generally do not require the use of an underlay for internal moisture control. Thermabar 344 must only be used in buildings with adequate means of ventilation, moisture and condensation control. Buildings incorporating high moisture loads such as swimming pools, freezers, cool stores, open liquid containers and moisture generating plants require specific design and are outside the product’s usage and BRANZ Appraisal scope.
For passive ventilation of the roof space, it is recommended that all roof underlays are terminated at the ridge, and if not it should be slit or slotted to allow for passive ventilation. (For further information refer to the NZ MRM Roofing Code of
Practice).
Standard Thermakraft warranty applies. Refer to Thermakraft Warranty Statement for further details. This item is available online here or call 0800 806 595.
