Internal wall insulation – Pavatherm Profil 

Pavatherm Profil wood fibre internal insulation boards are:-

  • highly hygroscopic, wet-process wood fibre boards for internally insulating historic masonry.
  • ideal for insulating the interior of masonry which is very sensitive to moisture.
  • able to store and release significant amounts of moisture to prevent damage to the building fabric.

Prices: from £5.66 + VAT per board

Product overview.

Where are they used?

  • The Pavatherm Profil boards are used for internal wall insulation on the inside of external masonry walls.
  • They can be used on floors for thermal and acoustic insulation
  • The boards can be used on timber partitions but would normally need a carrier board behind, such as OSB.

How are they used?

  • Walls should be flattened first using Baumit RK38 lime plaster if necessary. The maximum variation across the board should be no more than 3-4mm to ensure full contact with the substrate.
  • The surface of the wall should have a layer of Baumit RK70 lime plaster applied to the surface which should then be combed with a 20mm round notched trowel to ensure an even 4-5mm layer.
  • The Pavatherm Profil boards should then be pressed into this and ‘wiggled’ slightly in to their final position.
  • Ejot H3 75mm fixings should be used to secure the boards at a rate of 4 per board. Drill these into position but do not hammer home until all surrounding boards are fixed.
  •  Leave the boards for at least 24 hours for the RK70 N to set. Once set a plaster coat of RK70 N can be applied to the surface of the boards.
  • Comb the surface of the plaster with a 20mm round notched trowel to ensure an even 4-5mm layer.
  • Whilst still wet, lay in the fibreglass reinforcing mesh and trowel it in until it sinks in and disappears into the plaster.
  • Leave to cure for 1mm per day (4-5 days) and then apply a finish coat of either Baumit RK70 N or Baumit Klima Glatte.
Technical Details

How much will you need?

  • The Pavatherm Profil boards are 1080 x 560mm and 40mm thick, they cover an area of 0.6048m² per board.
  • Allow at least 5% for wastage depending on the complexity of the surface.

Product overview.

Where are they used?

  • The UdiSPEED boards can be used internally or externally on timber frames.
  • They’re really tough so ideal for commercial or public situations, such as schools.
  • On partition walls to take a plaster.
  • In recording studios where sound deadening is important.

How are they used?

  • The UdiSPEED boards are mechanically fixed to timber frames or to masonry structures.
  • As the are very rigid, when using on masonry, apply a layer of render to the back of the boards just before fixing to the wall to ensure full contact.
  • The first course of UdiSPEED boards should start at least 300mm above ground level.
  • There should be no horizontal or vertical joints within 300mm of the corners of any openings. If this is not possible then UdiSPECIAL ADHESIVE must be used to glue the joints in these areas.
  • UdiSPEED wood fibre insulation boards can be cut with a circular saw or with a sharp hand saw (although this is very slow) and then fixed to timber studs/panels.
  • The insulation boards should be laid in horizontal rows with the tongues pointing upward and firmly mechanically fixed with UdiASSEMBLY fixings, using an average of 9 fixings per m².

How much will you need?

  • The UdiSPEED boards are 1290 x 780mm and 40mm thick, they cover an area of 1 m² per board. Allow at least 5% for wastage.

What happens if they get wet?

  • Its never ideal to let wood fibre insulation boards get soaked by the rain, however, should it happen they will dry out again and be just as robust.

What is their thermal conductivity?

  • The boards are very high density at around 240kg/m³ and so their conductivity is a little higher than other wood fibre boards at 0.049 W/mK. However, they make up for this by being much better at absorbing sound and also by adding a lot of thermal mass the a structure.

Material in action.

Here you can see the Pavatherm Profil/Pavadentro systems and how they are built up against the wall. The grey layer immediately against the wall is the levelling plaster and the next lighter layer is the Baumit RK70 N. 

On the surface of the wood fibre boards you can see the two plaster layers with the mesh in between and then the final decorative coat.

If you have any questions on how to detail this system please feel free to contact us.

Carriage is typically calculated at £100 + VAT per pallet and all orders will be sent on a pallet. This price does vary if delivery is required to remote locations. If you require only a few boards we may be able to get slightly cheaper shipping so please contact us for a more accurate price.

If this purchase is part of a larger order, please do not use these transport costs as the goods will grouped together for a much more competitive rate.
