Insulation for parapet walls

PERINSUL HL

The junction of an external wall and flat roof is a difficult part of a building to design well. Continuing the wall above roof level to create an upstand also creates a thermal bridge, that was very difficult to detail before the development of PERINSUL HL insulation for parapet walls.

Masonry

PERINSUL HL courses in with a masonry external wall at the level of the flat roof insulation, creating a connection with the wall insulation and eliminating the thermal bridge. The product is laid in mortar just like masonry, meaning no change in construction method or delay to the progress of work.

system characteristics

  • Proven concept: PERINSUL HL performs for the life of the building. Excellent dimensional stability means it does not degrade or shrink in situ.
  • Energy efficiency: significantly reduces heat loss through a hard-to-insulate thermal bridge.
  • Load-bearing: higher compressive strength than all other common insulation materials.
  • Healthy living: improves occupant comfort and removes the risk of surface condensation and mould growth.

How to install PERINSUL HL

in parapets

Internal wall base insulation
How to install PERINSUL HL under window and door sills
Doors and full-height windows form part of a building’s thermal envelope, and should therefore be installed in line with the surrounding wall insulation for best effect. This is not always possible, however, and they are often supported by the inner leaf blockwork of a masonry wall, which acts as thermal bridge.
