Aerofil 1

Product Decsription

Low density, compressible, closed cell polyethylene filler for structural expansion joints and building facades.

Product Applications

Aerofil® 1 is a white, inert, preformed, closed cell, polyethylene joint filler suitable for structural movement joints in concrete, brick and blockwork. Aerofil 1’s low compressive strength prevents the transfer of load across joint interfaces and makes it ideal for forming soft compression joints and expansion joints in brickwork facades as recommended by

BS 5628: Part 3: 1985 Use of Masonry Clause 20.4. Aerofil 1 is equally suitable as a low compression joint filler for bridge expansion joints as specified in Department of Transport, Scottish Development Dept., Welsh Office, Dept. of the Environment for Northern Ireland, Specification for Highway Works Series 1015 where it is essential to prevent transmission of horizontal forces to the abutment walls. Aerofil 1’s low density is also useful for forming isolation joints for machine bases or similar locations.

The closed cell construction also prevents moisture absorption. Aerofil can be used on internal finishes as a gap filler or backing filler to walls, pipes, kitchen and sanitary ware before sealing with a surface sealant.
