Ultra-thin wood fibre insulation boards – UdiIN 2CM

UdiIN2CM wood fibre internal insulation boards are:-

  • a fantastic way to add insulation when space is tight.
  • ideal for insulating around stairs, narrow corridors or where windows are very close to corners.
  • very fast to install, no fixings required.
  • perfect for listed and older buildings.
  • a great way to quickly renovate old plaster surfaces.

Product overview

Where is it used?

  • The UdiIN2CM boards are used internally on masonry walls.
  • The boards can be applied over existing stable plasterwork or bonded directly to masonry substrates.
  • UdiIN2CM can also be bonded to ceilings and pitched roof surfaces for renovation.
  • Particularly useful in areas where space is at a premium.

How is it used?

  • A 6mm layer of Baumit StarContact render is applied to the surface as an adhesive layer, using a notched trowel.
  • The boards are cut to size using a circular saw or jigsaw and then pressed into the adhesive layer with a light, circular motion.
  • After a drying time of around a day the surface of the boards can be plastered with a further 6mm layer of Baumit StarContact render, incorporating the strengthening mesh and left to dry.
  • The Baumit StarContact can be used as a slightly grainy finish or other non-gypsum finishes (such as lime or clay) can be applied, such as Baumit Klima Glatt or Baumit RK70N plaster.

How much will you need?

The UdiIN 2CM boards are 1150 x 750mm and 23mm thick, they cover an area of 0.8625 m² per board. Allow at least 5% for wastage.

Frequently asked questions

Do the boards need fixing?

No, they are purely adhesively fixed and don’t need any sort of fixings, making them ideal for soft, friable substrates.

What is their thermal conductivity?

The official calculated thermal conductivity is 0.089 W/mK. However, we’ve measured them in-situ with our U-value testing kit and they seem to perform at 0.049 W/mK.

How to install wood fibre insulation boards

Play Video

This video shows the basics of how the adhesive lime plaster is applied and how easily the boards are applied to the wall. The whole process is rather like tiling really.

Once the boards are bonded and the adhesive plaster has set, the boards can be finished with a thin layer plaster coat, incorporating the reinforcing mesh, and then skimmed with a lime finish coat.
