Description

Isover Timber Frame Batt 35 is a glass mineral wool batt that can be used in timber frame walls. The resilient and flexible batts can be friction fitted between standard timber studs, ensuring straightforward installation and helping to minimise gaps and therefore maximise thermal performance.

Key Benefits

  • Thermal Insulation - Thermal conductivity of 0.035 W/m.K. Helps to reduce heat loss within the building envelope and as a result decreases energy costs.
  • Isover Timber Frame Batt 35 has Eurofins Indoor Air Comfort® Gold Certification - the highest accreditation for indoor air quality.
  • Fire Classification - Achieves a Euroclass A1 Reaction to Fire classification, according to EN 13501-1. For enquiries regarding test data for Reaction to Fire classifications, please contact [email protected].
  • Ease of Install - Straightforward to handle, cut and install with minimal waste (off-cuts can be reused). Friction fits between 600mm timber stud centres with no need for additional fixings.
  • Sustainability
    • Contains Recycled Glass - Isover Timber Frame Batt 35 contains recycled glass. A combination of 52% externally sourced recycled glass and 30% internally sourced glass cullet.
    • Renewable Electricity - All electric equipment in the plant powered by 100% renewable electricity.
