Suspended Timber Floor

SuperQuilt is often used in Suspended Timber Floors. YBS SuperQuilt is fully LABC & BDA certified, to be used in Suspended Timber Floors. The beauty of this solution is that SuperQuilt  often achieves building regulations on its own without any other materials. This makes it easy and also cost effective, without compromising on the thermal performance.

Please see below 2D diagram demonstrating this application and also an image which shows SuperQuilt Installed.

Suspended Timber Floor | YBS SuperQuilt should firstly be rolled out over the joists. The insulation should then be recessed in-between the joists by a minimum depth of 50mm.

To ensure the SuperQuilt is recessed correctly (creating an air cavity) – we advise fixing the multifoil with our YBS Saddle Clips. To fix the SuperQuilt in place we would either recommend stapling into place, or fixing down with YBS Saddle Clips, Saddle clips will ensure a cavity is created of 54mm.

Any overlaps when installing SuperQuilt on suspended timber floors should be tightly lapped and stapled, however left un-taped.

Overlaps being left un-taped will allow any moisture accumulation to dissipate. You should however ensure that YBS SuperQuilt is fully taped and sealed around the perimeter using our Thermaseal Foil Joining Tape.

Timber engineered decking can then be fixed at 200mm centres with 37mm screws into the joists.

Suspended Timber Floor | YBS SuperQuilt is an ideal solution for insulating suspended timber floors, as it wouldn’t raise the height of the floor, and would save labour time dramatically as there is no requirement for cutting rigid PIR boards such as Kingspan or Celotex.

If there is no requirement to achieve a specific U-value, you may be interested in our cost effective multifoil insulation EcoQuilt Expert, which would be installed in the same manner as YBS SuperQuilt.

You will notice on the U-value table, the U-value achieved is determined by your P/A ratio

You will be able to see how to calculate a P/A ratio for your timber floor project – this is an example but is able to be applied to your project when replaced with your dimensions!

  • Floor Area in m² = 100m²
  • Perimeter of walls exposed to outside areas in m = 60m
  • 60 Divided by 100 = 0.60
  • P/A Ratio = 0.6
