DriTherm Masonry Slab

DriThermCavitySlab

Earthwool® glasswool: DriTherm® Masonry slabs are a new generation of softer, safer and more environmentally friendly glasswool insulation.

Earthwool glasswool: DriTherm Masonry slab is a silicone treated insulation product for strapping and lining of masonry walls.

Application

Earthwool glasswool: DriTherm Masonry slabs provide a cost-effective thermal and acoustic barrier for energy-efficient construction. The consistent quality, low dust, and clean-cutting resilient glasswool makes installation fast. Earthwool glasswool: DriTherm Masonry slabs can be used in masonry cavity external walls and are installed to fully fill the cavity. Earthwool glasswool: DriTherm Masonry slabs are 600mm wide to suit standard vertical wall tie spacings, ensuring a closed joint with adjacent slabs.

Proven Performance

  • Preferred by professional installers concerned with quality, appearance and productivity.
  • Excellent acoustical properties reduce sound transmission in the home when properly installed in wall systems.

Durability

  • Earthwool glasswool is odourless, rot proof, non-hygroscopic, does not sustain vermin and will not encourage the growth of fungi, mould or bacteria.

Vapour Resistivity

  • Earthwool glasswool: DriTherm Masonry slabs offer negligible resistance to the passage of water vapour and have a water vapour resistivity of 5.00MNs/g.m.

Moisture Resistance

  • Earthwool glasswool: DriTherm Masonry slabs comply with the Deemed to Satisfy provisions of the BCA in relation to cavity wall insulation and will not affect the moisture  resistance of the wall.
  • Tests by the British Board of Agrément confirm that Earthwool glasswool: DriTherm Masonry slabs will not transmit water to the inner leaf. Nor will they transmit moisture by capillary action across the cavity or from below damp proof course level.

Superior Handling

  • Highly resilient insulation recovers quickly to full thickness for a snug fit and superior finished aesthetics.
  • Consistent quality materials feel good, cut easily and install fast.
  • Low dust for easier handling and increased productivity.

Convenient Packaging, Easier Handling

  • Earthwool glasswool is packaged in a strong, white poly bag that offers excellent protection from abuse, dust and moisture.
  • Earthwool glasswool packages feature easy to follow installation instructions.
  • MasterBag insulation units (containing multiple packs) ensure reduced handling costs with improved compression – more square metres per bag, more square metres per truck load, fewer trips to the job site and less warehouse space for storage.

Superior Service and Support

  • Knauf Insulation is focused on providing first class customer service, producing high quality products and ‘in full on time’ deliveries.
  • Knauf Insulation recognises the need to establish, develop and support a professional network of distributors and re-sellers in order to service a growing insulation market.
