APPLICATION

Suitable for new build and refurbishment. Above floor slabs and below floor screed.

INSTALLATION

Xtratherm Thin-R Hyfloor XT/HYF boards should be stored off  the ground, on a clean, flat surface and must be stored under cover. The polythene wrapping is not considered adequate protection for outside exposure.

Below Floor Slab
  • Lay the hardcore in layers (150mm to  225mm). Each layer should be well compacted, with the surface blinded with quarry dust or sand to provide suitable surface for laying DPM.
  • A damp proof membrane e.g. 1200 gauge polythene or radon barrier should be laid over blinding with joints taped to prevent passage  of ground moisture, it should be carried up the wall until it meets and seals with the DPC.
  • Hyfloor should be laid with closely butted T&G joints, laid staggered with a break bonded pattern and fitted tightly at edges and around any service penetrations.
  • Place a layer of polythene over any under floor insulation to act as a separating layer.
Below Floor Screed
  • Ensure that the floor slab or beams onto which the insulation is being laid is level, a blinding of sand may be required.
  • The concrete floor over which the insulation  is to be laid should be left as long as possible to maximise drying out, in accordance with BS8203: 1996 Section 3.1.2.
  • The minimum thickness of sand and cement screed is 65mm for domestic construction and 75mm for most other buildings.
