ENERGY RATING IN ACCURATE®
TECHNICAL GUIDANCE FOR THERMOSEAL™ WALL WRAP XP
When modelled correctly, reflective laminate wall wrap products can contribute an additional air-gap
R-Value to a wall system, improving the overall thermal efficiency of the home. To ensure that the additional
air-gap R-Value is correctly calculated, this Building Knowledge Series by CSR Building Products provides
guidance on how to accurately input Bradford Thermoseal Wall Wrap XP into AccuRate.
PRODUCT SPECIFICATION
Thermoseal Wall Wrap XP has a reflective and non-reflective surface with the following properties:
- The reflective surface faces outwards and has an emittance of 0.09
- The non-reflective surface faces inwards and has an emittance of 0.9
BRICK VENEER CONSTRUCTION EXAMPLE
This example uses a Brick Veneer wall with a 110mm extruded brick,
Thermoseal Wall Wrap XP, R2.5 wall batts and 10mm plasterboard lining.
- Layer 1: Contains the 110mm extruded brick
- Layer 2: Insulation placeholder contains the 40mm nominal 0.1/0.9 reflective
air gap for Thermoseal Wall Wrap XP
- Layer 3: Insulation placeholder contains the wall batt
(select required wall insulation: R1.5/R2.0/R2.5/R2.7)
- Layer 4: Is the 10mm plasterboard
SIMULATION SPECIFICATION
This product simulation applies to AccuRate.
LIGHTWEIGHT CLAD CONSTRUCTION EXAMPLE
This example uses a 9mm Cemintel™ Expresswall™ panel on a 35mm top hat,
Thermoseal Wall Wrap XP, R2.0 wall batts and 10mm plasterboard lining.
- Layer 1: Contains the 9mm Cemintel Expresswall panel
- Layer 2: Insulation placeholder contains the 40mm nominal 0.1/0.9 reflective
air gap for Thermoseal Wall Wrap XP
- Layer 3: Insulation placeholder contains the wall batt
(select required wall insulation: R1.5/R2.0/R2.5/R2.7)
- Layer 4: Is the 10mm plasterboard
THERMOSEAL WALL WRAP XP - UNDERSTAND THE XP DIFFERENCE
When the building stud cavity is filled with wall batt insulation, conventional (single sided inward facing) wall wraps are no
longer able to contribute an additional air-gap R-Value to the wall system. Thermoseal Wall Wrap XP overcomes this problem
by using an outward facing patterned antiglare surface to create a more energy efficient wall system by boosting the
performance of the wall batt insulation.
