“The best insulation for use within any timber roof, wall, or floor. It fills all voids and doesn’t slump meaning it continues to performs as it should indefinitely” – Chris Brookman

 

Product overview.

Where is it used?

  • In all timber structures, such as floors, walls and roofs.
  • In internal partitions or suspended floors as sound insulation.
  • Within historic timber frames where keeping the moisture content low is critical.
  • Inside recording studios or other sound insulated structures.

How is it used?

  • SteicoFLEX flexible wood fibre wool is simply pressed in between timbers or laid flat on ceilings.  
  • It is designed to be fitted between timbers at 600mm or 400mm centres but if it does need to be cut in any significant quantity then an ‘Alligator saw’ is the best tool for this.
  • It should be cut 5-10mm wider than the void into which it is being fitted so as a snug fit without voids is achieved.
  • SteicoFLEX is not suitable for cavity wall insulation or use in a masonry cavity.
Technical Details

How much will you need?

What is their thermal conductivity?

Material in action.

Here you can see the flexible wood fibre insulation being installed into a roof, under some of the UdiTOP wood fibre sarking boards. The SteicoFlex was installed in showery weather and did get wet from time to time. Whilst this isn’t what we’d recommend, the Flex dries very fast ensures that the timber structure dried out quickly too.

Carriage is typically calculated at £65 + VAT per pallet and all orders will be sent on a pallet. However, we cannot always send full pallets as they exceed the maximum height for some transport networks. Please contact us to discuss the best way to deliver in your area.

This price does vary if delivery is required to remote locations. If you require only a few boards we may be able to get slightly cheaper shipping so please contact us for a more accurate price.
