Schneider Multitherm 140 (Plain Edge)

For detailed application advice see our Internal Wall Insulation System

For plaster options please see Plastering onto boards 

Preparation 

• The substrate must be dry, clean and level.
• Remove loose layers of plaster, and level undulations in the substrate with a suitable lime plaster
• Gypsum or cement plaster should be removed and replaced with lime
• Drying times of about 1mm per day of plaster must be observed before installing the woodfibre boards

Cutting 

• All standard cutting equipment for cutting wood, such as bench-type circular saws and hand­held circular saws, can be used to cut MULTITHERM 140 boards to size.
• The dust which is generated when cutting wood fiber insulation boards, should be extracted by means of a vacuum extractor and it is advisable to wear a dust mask.
• The boards can be recessed to accommodate cables or conduits if required.

Installation 

• Avoid board edges at the corners of window openings, otherwise there is increased risk of cracks in these areas
• Install the boards on a staggered basis with an vertical offset of at least 25 cm to each other
• The edges of the board must be precisely fitted together at all junctions and should not have adhesive between the boards.
• Boards must be installed with full adhesive coverage – dot and dab installation is not acceptable.
• Do not use MULTITHERM 140 as load-bearing component

Storage 

• The boards must be stored in a dry place and protected against UV rays and mechanical damage.
