Metal Flashings

Profiled Foam Strip - Ecofoam

Product Description

Ecofoam is a polyethylene closed cell foam produced by Tetral Industries Ltd (Christchurch) for use in providing long life seals against water, draughts and pests, and is commonly used between the underside of flashings and roof or wall sheet profiles.


  • High tensile and tear strength.
  • Resistant to most chemicals and biologically and physically inert.
  • Resists embrittlement due to UV exposure.
  • Profiled to fit under all the Dimond roofing profiles.
  • 20mm wide with dovetailed interlocking ends.


Ecofoam is suitable for use with any metal roofing or cladding materials and with translucent sheeting. The carbon black contained in Ecofoam is less than 0.065% by weight and it is therefore suitable for use with Zincalume, Colorsteel and ColorCote products. Block foam – 30 x 30mm polyethylene closed cell foam. Usually ordered in for specific jobs. Allow a 14 working day lead time, for date of order to supply.

The range delivers a wide choice of specifically designed innovative products to prevent the ingress of water and dust at service pipes, flues and ducts that penetrate roofs or walls. Dektite EPDM and silicone is compatible with Zincalume, galvanised steel, aluminium, copper, lead, asbestos cement, and even timber. Self seals at the top of the cone.

Dektite sizes are available to accommodate pipe/flue diameters from 1.0mm to 610mm.
