Thermoseal Wall Wrap XP in FirstRate5 from CSR Bradford

ENERGY RATING IN FIRSTRATE5®
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 FirstRate5®.

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
To simulate this product in FirstRate5 it is as simple as using the Wall Builder and selecting a reflective air-gap of 0.1/0.9 with the appropriate thickness to suit the wall cavity.

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
