Square edge wood fibre insulation boards – UdiTHERM SK

UdiTHERM wood fibre insulation boards are:-

  • simple, breathable, non-renderable wet-processed wood fibre insulation boards.
  • high density so great for using on ground or suspended floors for insulation and sound deadening.
  • used in walls and roofs for acoustic insulation and thermal mass.
  • for use behind the UdiTOP, UdiSPEED or UdiUnger-Diffutherm boards to improve insulation levels.
  • available in different strengths depending on usage.

Prices: from £3.53 + VAT per board

“A super impact absorbing board that is a brilliant cushion below floor boards and systems like the Lithotherm under floor heating tiles” – Chris Brookman

 

Product overview.

Where is it used?

  • UdiTHERM SK wood fibre boards are square edged and used for internal and external solid wall insulation or for direct fixing to timber frames.
  • It is also used under domestic flooring as an insulation and sound deadening layer.
  • The boards can be used as a very effective sound absorber in walls and floors to prevent reverberation within rooms.

How is it used?

  • As internal/external wall insulation UdiTHERM boards should start at least 300mm above the ground level and joints should be staggered with UdiSPEED/UdiUnger-Diffutherm boards. Use 4 fixings per m² to hold the boards.
  • In floors the boards can be placed or bonded to the floor before covering. Try not to use screws/nails if sound insulation is needed.
Technical Details

How much will you need?

  • The UdiTHERM SK Insulation boards are 1350 x 600mm or 0.81m².

Are they very soft?

  • The boards have a lower compressive strength than many of our other boards but that is useful when it comes to impact and sound absorption.

What is their thermal conductivity?

  • Although the density of the UdiTHERM boards is more than three times that of the SteicoFLEX at 160 kg/m³, their thermal conductivity is the same at 0.038 W/mK

Material in action.

Here you can see the UdiTHERM SK boards being used underneath a layer of UdiTOP wood fibre sarking boards. Rather than try and use a single layer at 160mm thick, it was broken up into the 100mm UdiTHERM you see in the photo with a layer of 60mm UdiTOP covering it and protecting it from the elements.

This combines the best of both worlds with the high density wet processed fibre boards which give the highest thermal mass and the best thermal shielding from summer sun.
