Blown Floor Insulation

Excellent solution to significantly reduce noise between floors
  • As additional part of Redplug’s drive to maximise the solutions available for our blown Rockwool insulation service we have now developed a thorough method to insulate traditional suspended floors that have accommodation below such as living rooms, bedrooms, bathrooms, playrooms commercial premises etc.

    We can either blow Rockwool 3 in 1 fireproof insulation to fill the joist voids via 32mm holes drilled by us @ approx. 1000mm centres per each run of joists or by lifting a small number of floorboards counter to the joists and then blow the material through the length of the joist void. Typical densities are in excess of 30kg/M3. This is an excellent solution to significantly reduce noise between rooms either above or below while having the added benefit of reducing the potential for fire to transfer through the void.

    If you are interested in using our blown floor insulation service, please email your address and a contact telephone number including area dimensions and joist depth where possible and we’ll endeavour to supply costs by return.

    Finally, sorry but we don’t offer a service to fill holes or lift or relay floorboards after the installation. Installation times vary significantly dependent on floor type.
