Description

Thermafloor Undertile Heating is an electric heating system intended for floor surface warming of stone and ceramic tile finishes in residential and commercial buildings, including wet areas.

Scope

1. Thermafloor Undertile Heating has been appraised for use in internal wet and dry areas of buildings, within the following scope:

• on a structural substrate of concrete, plywood or fibre cement compressed sheet (excluding particle board flooring); and,
• with fibre cement tile underlay where required; and,
• when protected from physical damage by a screed and ceramic or stone tiles; and,
• where floors are designed and constructed such that deflections do not exceed 1/360th of the span; and,
• where the position of movement and control joints within the substrate are accounted for and reflected in the screed and ceramic or stone tile finish; and,
• where floors are designed not to exceed a continuous operating temperature of 35ºC.

2. Thermafloor Undertile Heating must be finished with a stone or ceramic tile floor covering. Stone and ceramic tile finishes are outside the scope of this Appraisal.

3. A BRANZ appraised membrane system must be used in wet areas. The design and application of the wet area membrane system is outside the scope of this Appraisal.
