Earthwool Underfloor Insulation Batts

Underfloor Batts InsulationEarthwool® Underfloor batts are a new generation of super-soft, sustainable glasswool for the thermal insulation of under floors. The product is specifically designed for overhead installation in tight crawl spaces and comes in pre-cut rectangles at 480mm and 610mm widths.

Application
Earthwool Underfloor batts provide a cost-effective, thermal and acoustic barrier for energy-efficient construction. The consistent quality, low dust, and clean-cutting resilient glasswool makes fabrication easy and installation fast.
Earthwool Underfloor batts provide high thermal performance and comfort - cool in summer and warm in winter. They are highly resilient, recovering quickly to full thickness.

Proven Performance

  • Preferred by professional installers concerned with quality, appearance and productivity. 
  • Excellent thermal performance - the wind wash barrier ensures the thermal performance is not affected by air movement under the floor. 

Durability

  • Earthwool Underfloor Insulation Batts are odourless, rot proof, non-hygroscopic, do not sustain vermin and will not encourage the growth of fungi, mould or bacteria. 

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 Underfloor Insulation Batts are packaged in a strong, white poly bag that offers excellent protection from abuse, dust and moisture. 
  • Earthwool Underfloor Insulation Batt packages feature easy to follow installation instructions. 
  • MasterBag batt 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 totally focused on providing first class customer service, producing high quality product and ‘on time in full’ 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.
