Thermal Values

  • Structural timber stud dimensions are critical factors especially in prefabricated units and increasing stud depths is not always practical.
  • Despite this, stud sizes may need to be increased to accommodate more insulation in order to comply with the thermal regulations.
  • Tyvek Reflex can help to alleviate this due to the additional thermal resistance that it provides.
  • The thermal benefit provided by Tyvek Reflex compared to a standard breather membrane is demonstrated in below tables including the usage of the airtight vapour control layer DuPont™ AirGuard Reflective.
