“A really robust and breathable membrane, great for laying over wood fibre sarking boards to create watertight, flat roof structures” – Chris Brookman

Product overview.

Where is it used?

  • Ampatop Seal is used on very shallow pitch roofs over wood fibre sarking boards, down to 5° pitch to ensure a fully watertight, breathable seal is formed.
  • This product can also be used down to a 10° pitch without any sarking board support.

How is it used?

  • Ampatop Seal weldable breathable membrane is designed to be used in very low pitch (flat) roof structures.
  • All joints should overlap by at least 100mm and all joints must be welded with Ampacoll LiquiSeal adhesive.
  • Roof pitches between 5° and 10° must use a sarking board to support the membrane and prevent pooling.
  • For full details on how to install this membrane please download the installation guide.
Technical Details

How much will you need?

  • Each roll of Ampatop Seal breathable membrane is 30m long and 1.5m wide. It covers an area of 45m2 including overlaps.

How long can I leave it exposed?

  • This membrane is very UV stable and can withstand up to 3 months of weathering without deterioration. Beyond this the sun can begin to degrade the strength and weather resistance of the membrane.

Do I need to tape the joints?

  • All the laps must be sealed but this would be with either the solvent welding glue or by heat welding the laps

Material in action.

This image shows the Ampatop Seal membrane being used on a low pitch roof. Numbers 1 and 2 are the Ampacoll LiquiSeal and LiquiSeal Applicator, used for bonding the laps in the membrane. Number 3 is the Ampatop SealStripe which is a strip of the membrane used for forming around penetrations, such as roof lights. Number 4 is the Ampacoll TubeSeal which is a purpose made collar for sealing around any vent pipes or other protrusions and finally, number 5 is the Ampatop SealEdge eaves roll which is a UV resistant roll suitable for edging the membrane along the eaves. This ensures a permanently UV stable and watertight edge is formed.
