This image shows the UdiRECO boards from the side. You can see the flexible layer on the back which allows it to mould itself to uneven surfaces. This shows the surface of the UdiRECO boards with the fixing holes pre-countersunk so that the fixings end up perfectly flush with the surface once installed. Here you can see an old stone building in Somerset being covered with the UdiRECO boards. Using the template we loan to our customers makes sure you only fix into stones and not waste time and fixings trying to fix in to the joints. Back-to-Earth-015_clipped_rev_1

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.

Frequently asked questions

What is their thermal conductivity?

The thermal conductivity of the boards is a combination of the two layers. The front, rigid layer has a conductivity of 0.048 W/mK and is always 40mm thick. The softer section at the rear varies, depending on the overall thickness but has a conductivity of 0.039 W/mK.
