AlphaChem sealant backer rod 10mm non absorbent compressible grey closed cell polyethylene foam backs up windows door frames expansion joints and also acts as bond breaker material.

Insert into a joint to control sealant depth and create a back stop to allow the proper depth of sealant ready for tooling.

Creates the correct depth to width of sealant a very important part of the sealant application process, it creates a flexible joint that is 2 sided not 3.

The correct width to depth of sealant allows for the correct amount of movement in the sealant being used whether its around door frame, window frames, floor or wall expansion joints.

Also has the added benefit of saving money on wasted sealant by far the most expensive side of the job.

3 sided sealant joints will not have the same movement capabilities as a 2 sided joint they will be hard and have little movement and will fail over time.

The normal joint requirement is 2 wide to 1 deep but check with the silicone or sealant literature.
