Conventional foil faced impervious non breathable pir pur boards are commonly used in suspended floor upgrades and this can provide some thermal performance benefits in the short term at least.
Diy suspended floor insulation.
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 garage.
If you want to do it yourself materials can normally be purchased from larger diy stores.
Unfortunately if there is no access to the underneath of the suspended floor then the job is made more difficult because the floorboards need to be removed prior to insulating.

Rockwool offers stone wool insulation products to meet and exceed thermal regulations in floor constructions as well as solutions for separating floors to prevent heat transfer between the upper and lower floors.
Many older houses with suspended timber floors have big draughts and inadequate floor insulation.
This can cause cold feet as well as higher energy bills.
Floorboards will rot without adequate ventilation though so don t block underfloor airbricks in your outside walls.
Installing underfloor insulation can address both these problems and give a payback on your investment in 5 years or less depending on whether you do it as a diy job or use a professional.

Interior wood framed floor insulation.
All ground floor constructions unless very large commercial floors will require some insulation to be included within the floor zone to comply with building regulation requirements.
Time to get building again.
