Wood fibre insulation boards for uneven walls – UdiRECO

UdiRECO wood fibre Insulation Boards are:-

  • An eco friendly, external insulation for solid walls which aren’t flat.
  • A great product for retrofit/refurbishment, especially at thicknesses over 100mm.
  • Ideal for rough rendered or uneven stone/brick walls
  • Excellent at keeping you warm in the winter and cool in the summer.
  • An insulation that keeps your walls breathable, preventing moisture related issues such as mould.

Product overview

Where is it used?

  • Externally, for new-build and retrofit on to all types of masonry. The board has a unique backing which moulds itself to uneven or rendered surfaces, avoiding the need to render walls flat first.
  • Undersides of uneven rafters in old houses.

How is it used?

  • In short, by screwing it to the wall and rendering it. Simple. For the full guide please download here or read through the quick summary below.
  • Plan out your wall first. The first course of UdiRECO boards should start at least 300mm above the ground level, above the plinth insulation.
  • Measure the position of window openings so that there are no horizontal or vertical joints within 300mm of the corners of any openings. If this is not possible then the UdiSPECIAL ADHESIVE must be used to glue the joints in these areas.
  • UdiRECO insulation boards should be laid in horizontal rows, with the tongues pointing upward and loosely fixed with two UdiASSEMBLY fixings to begin with. Once the entire face is covered with the boards start at the bottom and install the rest of the fixings, a total of 8 per board.
  • A full installation guide and specific junction details can be found here.

How much will you need?

UdiRECO boards cover 1285 x 775mm, or 0.996m2 per board. We suggest you allow 5-10% waste depending on how many corners or windows are involved.
