Airtightness Kit For Suspended Floor Insulation

From £137.90 ex VAT

Designed to reduce draughts and heat loss, improve the energy performance of a building and protect it against interstitial condensation which can cause mould and rot.

Airtightness Sealing Tape
The airtight tape is used to seal any overlaps and penetrations and ensure a full airtight envelope. 3 rolls of tape are recommended per 75m^2 of membrane.
Vapour Control Membrane
The control membrane prevents warm air leaving through the floor, which in older buildings is a common issue. It will also stop draughts and save you money by stopping warm air from leaving your house.
Breather Membrane
The breather membranes helps regulate the humidity inside the floor itself, ensuring it's longevity, stopping damage and condensation build-up.

The PHS Suspended Floor Kit is designed to reduce draughts and heat loss, improve the energy performance of a building and protect it against interstitial condensation which can cause mould and rot.

How it Works:
  1. To correctly insulate a suspended floor, it needs to be airtight to function properly and prevent risk to the construction. The Vapour Control Membrane prevents condensation, stops cold air entering the building and warm air from leaving.
  2. The Breather Membrane is placed on the bottom. The printed side face to the cold. The membrane should be wrapped around the joists. Securing battens to the membrane and the joists followed by wrapping any overlaps and penetrations with airtight tape.
  3. Placing insulation in-between the joists.
  4. Covering the top of the floor in a vapour control layer and sealing overlaps with airtight tape.
  5. Placing floorboards overtop.

Application

Aplication Guide:
  • PHS 120 Breather Membrane must be installed in accordance with the relevant sections of BS 5534:2018 and
    NSAI S.R. 82:2017 and it’s fixing instructions.
  • PHS 120 Breather Membrane is designed as a secondary barrier to wind driven rain and snow, it should not be considered a primary waterproofing layer. Whilst the product is UV stable for up to 3 months exposure, good roofing practice dictates that the primary waterproofing finish (e.g. tiles, slates etc.) be applied as soon as practically possible.
  • PHS 120 Breather Membrane should be unrolled across the roof, starting at the eaves and working up the roof, it must be laid printed side up. With normal slates and tiles the membrane should be installed draped to a maximum 15mm into the void between the rafters in line with BS 5534:2018 and NSAI S.R. 82:2017 it can then be secured with the tiling battens.
  • This will leave sufficient space between the PHS 120 Breather Membrane and the tiles/slates for drainage and ventilation. When installed as a fully trusses supported system, is laid over on trusses and secured with counter battens. Alternatively the membrane can be installed over counter battens and fixed at 200mm centres using corrosion resistant galvanised clout nails. Tiling battens are fixed to the counter battens leaving a minimum airspace of 25mm between the roof sheet underlay and the tiles for drainage and ventilation.
  • In unventilated roof systems, vapour control measures are required below the insulation layer to restrict the flow of moist air from within the inhabited building into the roof space.
  • PHS 120 Breather Membrane should be turned up at abutments at least 100mm to prevent rain and snow being blown into the roof-space. 600mm reinforcing strips should be fixed at hips, ridges and valleys.
  • At the eaves, a felt support tray should be installed to prevent ponding behind the fascia. PHS 120 Breather Membrane should be laid over the support tray stopping short of the roof tile tails to prevent UV degradation of the underlay.
