Surface Bed Insulation

Looking For Surface Bed Insulation Options?

If you are looking to build a thermally efficient home or office then surface bed or under floor heating insulation is an important aspect of your build. This insulation layer is essential to ensuring that the building envelop is properly insulated from the ground up.

This is our retail portal. Contractors & Bulk Buyers should request access to our discounted Contractor & Bulk Buyer Portal.

  • Surface bed insulation is the layer of insulation that is placed above the compacted soil layer and below the concrete floor slab before it is cast.
  • The insulation layer prevents the cold ground soil from cooling the concrete floor slab.
  • It is a building requirement to install surface bed insulation when underfloor heating is going to be installed.

This will give you the cost per m2 comparison.
