- Improves the R-Value of the wall system by contributing a reflective air-gap R-Value
Reduces the transmission of water vapour through the building structure*
- Improves energy efficiency by reducing draughts allowing insulation to work more effectively
- Protects the building frame from decay by reducing the entry of wind driven rain and dust.
*If the membrane is to provide a continuous vapour barrier, all joins, penetrations and discontinuities should be sealed.
Bradford's Thermoseal range of wall wrap products provide a secondary protective skin to your home which can reduce draughts and help make your home more comfortable.
Thermoseal Reflective foil laminates are pliable, vapour barrier products that can provide an additional R-Value to a building system by using an air cavity (an air void in the building frame) to create an R-Value as part of the total wall construction. The type of wall construction, use of bulk insulation (wall batts) and the required air-gap R-Value from the wall wrap will determine the type of wall wrap that is suitable to the application.
The Thermoseal Wall Wrap range is predominately comprised of non-permeable polymer and paper reinforced reflective foil laminates. This range of tough yet lightweight wall wrap products is suitable for use in residential timber and steel framed construction.
As a general guide, reflective foil laminates require an air cavity adjacent to the reflective surface in order to generative an air-gap R-Value. Where the stud frame is filled with bulk insulation making contact with the wall wrap or the cavity between the wall wrap and the external cladding is eliminated, the wall wrap is unable to provide an air-gap R-Value.
As a result, it is important to select a wall wrap that has the reflective surface positioned on the correct side to contribute the desired thermal value in addition to the other protective benefits offered by the wrap.
