100mm Wood Fibre Insulation Sarking Boards - UdiTOP


Reason for clearance - Old style T&G profile, 31 available.

UdiTOP wood fibre insulation sarking boards are:-

  • brilliant for keeping you warm and dry in winter.
  • great for summer heat shielding, keeping your home cool.
  • the best way to form a warm roof which is completely vapour permeable.
  • quick to form a weather-tight covering without using membranes/felt.
  • eco friendly and easy to use.

Where is it used?

  • On top of your rafters, preventing thermal bridging and keeping noise out, especially for loft conversions.
  • Behind any cladding on walls on timber frames or masonry.
  • Any roofs where bats live. They get tangled in membranes!!

How do I use it?

  • The UdiTOP wood fibre insulation sarking boards should be laid on top of the rafters and fixed in place with counter-battens. 
  • For roofing applications the first row should start at eaves level and working in rows, work your way up the roof. 
  • To reduce waste the overhang from the first row should be trimmed off and used to start the second row and so on.
  • For use behind cladding the same principles apply.  When working on masonry structures, unless the wall is very flat, timber battens should be fixed to the surface first with UdiFLEX between the battens. The UdiTOP can then be fixed to these battens, avoiding any voids behind.
  • Any cut joints or corners can be glued with UdiSPECIAL ADHESIVE and taped over with UdiSTEAM Alubutyl tape to ensure weather-tightness. 

How much will I need?

The UdiTOP wood fibre insulation sarking boards are 2500 x 600mm (1.5m2).
Allow 5-10% wastage depending on the complexity of the roof/facade.
