Suspended timber floors located above an unheated space where the insulation is installed below the floorboards or timber decking timber floors situated above an unheated integral.
Suspended timber floor with floorboards removed for most heritage properties the most effective and appropriate way to insulate a suspended floor and improve its airtightness is to retrofit insulation beneath the floorboards between the supporting joists figure 2.
Thermal bypass affects performance so cutting out draughts is preferable.
To make sure the insulation boards are flush with the top surface of the joists they should be supported on minimum 25 mm x 25 mm treated softwood timber battens proprietary galvanised steel saddle clips or galvanised nails partially driven into the side of the joists.
