The problem is that doing this properly injecting the glue with the beads takes about 3 times longer than installing the beads alone.
Cavity wall insulation beads leaking.
Plumbing pipes and leaks copper water pipes in the wall are usually secure but occasionally one may develop pinhole leaks and spray enough water to cause insulation problems.
The process seems simple drill into the outer wall inject a fibre or bead insulation into the cavity make good the holes sit back and enjoy reduced energy bills.
If you re installing cavity wall insulation it s worth opting for a modern insulating material with proven performance.
Eps expanded polystyrene beads and polyurethane foam are the most commonly used these days and with good reason.
Why are the beads bonded together.
This is due to the capillary action of the bead allowing gravity to draw any moisture present down the inner surface of the outer leaf to drain away at foundation level.
Cavity wall insulation beads will not allow dampness or moisture to penetrate the cavity in a properly constructed wall.
When beads are injected into the cavity wall they are injected with a upvc glue which binds all the beads together.
