Barcode 5036684022774
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.
Can be used in building construction joint applications including steel work, steel roof construction, curtain walling and wall cladding panelling.

Choosing the correct size
Select a backer-rod diameter that is approximately 15 to 25% larger than the width of the joint to give a firm base that does not move when applying the sealant.
