Vapour control and air tight membrane – Ampatex Sinco – 1.5m x 100m

Ampatex Sinco vapour control and airtightness membrane is:-

  • a highly tear resistant fleece membrane, with an Sd value of 5m, that regulates the moisture flow through walls, roofs and floors.
  • finished with a smooth surface ensuring tapes bond incredibly well.
  • perfect for ensuring the correct moisture flow through building structures using timber and vapour open insulation materials.
  • an easy to use membrane for providing a continuous internal air tightness layer.
  • used as part of our roofwall and floor insulation strategies.

Product overview

Where is it used?

  • On the inside of timber frames/dry lining, on the inside of roof structures or on the top side of floors.
  • Ampatex Sinco can be installed from the outside of roof structures during refurbishment.

How is it used?

  • Ampatex Sinco vapour control membrane can be bonded, using Ampacoll DT double sided tape, to the underside of rafters or the inside of timber studs prior to being boarded over or counter battened.
  • If using on the inside surface of wood fibre insulation boards, apply Ampacoll Primax primer and Ampacoll DT double sided tape to the surface at regular intervals to allow the membrane to be bonded to the surface.
  • Once each row of membrane is in place simply tape the joints with Ampacoll INT airtightness tape.
  • All joints should overlap by at least 100mm and the perimeter should be sealed prior to counter battening or being over boarded with plaster board.
  • Once the joints are taped it forms an air tight, moisture regulating layer.
  • Any penetrations, such as joists, pipes, cables or ducts should be sealed with Ampacoll BK 535 penetration sealing tape.

How much will you need?

Each roll of Ampatex Sinco vapour control membrane is 100m long and 1.5m wide. It covers an area of 150m2 without accounting for overlaps.

Frequently asked questions

Do I need to tape the joints?

Yes, you should always tape the laps, usually with the Ampacoll INT or the XT tape. This ensures the air tightness of the membrane and that it functions correctly to reduce moisture flow through the walls from the interior.

What are its properties?

  • The Sd value of the membrane is 5m which is ideal for breathable wall constructions, such as where you’re using wood fibre insulation boards.
  • Ampatex Sinco is also waterproof so can be used when refurbishing a roof from the exterior.
  • It has good tear resistance, 160N/5cm, making ideal for use with blown insulation.
