DIY wall insulation

Making a dry liner with TONZON Thermosheets

 

An insulating dry liner is a simple way to insulate a wall. With TONZON Thermosheets you can build up an insulated dry liner, layer by layer, making the insulating air space as deep as you want. A capable DIYer can do this singlehandedly, right up to wall-finishing. stage.

 

Preparing the wall

 

It doesn't matter what kind of wall it is. Whether the original wall is single-layer brick, a cavity brick wall, concrete or wood, a dry liner using TONZON is always a solution. The surface of the wall to be insulated is also irrelevant. However, it is recommended that the wall is as even as possible. Very rough walls, e.g. when some parts are plastered and others aren't, can make it difficult to mount battens in level plane. This may cause problems later, when finishing the wall.

What you need

The insulation is applied in layers, alternating between foil and a 2-cm layer of air. TONZON Thermosheets are stretched over the entire wall. They are kept apart by a framework of battens. Battens and cold bridge breakers must alternate, per layer.

  1. Thermosheets (cut to size)
  2. Cold bridge breakers (available in the form of XPS strips)
  3. Foil glue
  4. Battens
  5. Hammer-in plugs (6-8 cm long)
  6. Electric drill

 

Taking measurements

 

The Thermosheets are available in wall height by up to 450 cm wide. The length required depends on the width of the wall and the number of layers of Thermosheets applied. Allow at least 20 cm extra length so that each sheet has enough slack.

Take the finish into account when determining the number of battens and cold bridge breakers. For example, if the dry liner consists of plasterboard sheets 60 cm wide, the battens should be 60 cm apart, measured centre to centre. The battens are mounted with two layers of cold bridge breakers per layer of battens. The cold bridge breakers are mounted as one block every 50 cm.

Foil adhesive is used to glue the edges of the wall and the XPS blocks. This requires about 40 ml of glue per square metre of surface to be glued. Use 80 ml of glue for a wooden surface. Use at least one 125ml jar per 10m² wall for a structure with 5 air layers.

Applying TONZON Wall Insulation

The insulation is applied in layers. The glue needs some time to dry. So start by spreading glue on the edges and the cold bridge breakers.
