Soffit insulation can be installed to the underside of metal decking or concrete floors in order to achieve a lower ‘U’ Value, in accordance with the Building Regulations and the minimum requirements for that element of the building.

A ‘U’ value is a measure of heat loss. It is expressed in W/m2k, and shows the amount of heat lost in watts (W) per square metre of material. The lower the ‘U’ value, the better the insulation provided by the insulating material and conversely, the higher the ‘U’ Value, the higher the heat loss.

Good ‘U’ Values are important measures for understanding the amount of energy that is needed to keep a comfortable inside temperature.

While the values do vary for each particular material and method of construction, the following systems can be installed to the underside of soffits in order to provide a lower ‘U’ Value:

  • Mineral Fibre Sprays
  • Mineral Fibre Board
  • Polyurethane Foam Board
  • Phenolic Foam Board
  • Laminated Hard Board / Insulation Systems (calcium silicate board bonded to either phenolic or mineral fibre insulation)
