Cladding and jacketing
Aluminium Polykraft / Polysurlyn
Moisture retarder coated aluminium jacketing
Aluminium sheet with a moisture retarder layer is used to stop jacket corrosion and reduce moisture migration to the metal. Poly Kraft is a multilayer composite film of kraft paper with plastic film, while Polysurlyn is a multilayer moisture retarder film based on the acid copolymer Surlyn and other polymers, usually polyethylene.

Thickness: 0.91 / 0.71 / 0.56 mm; Width: 1220 / 914 mm. If you need a size that is not listed, ask us and we will check what the manufacturer can make.
Where is Aluminium Polykraft / Polysurlyn used?
Typical uses: moisture retarder layer on aluminium jacketing; extra protection against moisture migration to the metal; mechanical protection to reduce corrosion on the inside face of metal jacketing; applicable to aluminium, stainless, AZ 60 galvalume, galvanised and aluminised steel.
Can SGPL supply and install Aluminium Polykraft / Polysurlyn?
Yes. We supply it on its own, or our own crews install it as part of our insulation cladding and finishing, hot insulation and cold insulation work. That starts with a site visit and a written specification, and ends with a joint measurement at handover.
Is Aluminium Polykraft / Polysurlyn in stock, and do you send a datasheet?
We hold Aluminium Polykraft / Polysurlyn at our Vatva GIDC (Ahmedabad) and Morbi stockyards. You can download the datasheet on this page, and we can send the test certificate with the dispatch. Send your enquiry before 4 pm and you will usually hear back the same working day.
