Bonded polystyrene bead insulation across Renfrewshire and Inverclyde
We cover 4 towns in Renfrewshire and Inverclyde: Paisley, Greenock, Newton Mearns and Renfrew.
Before any material is chosen, exposure is checked. Parts of Renfrewshire and Inverclyde face some of the heaviest wind-driven rain in the UK, especially exposed coastal and upland sites. Here the survey is stricter: some walls suit only certain certified systems, and some should not be filled at all.
Where a Renfrewshire and Inverclyde property has an extension or a conservatory, we check how the old and new walls meet, because that junction is often missed. Most Renfrewshire and Inverclyde houses built from the 1920s onwards have cavity walls, but the survey still checks each one: cavity width, debris, the condition of the brickwork and how exposed each wall is.
Building standards in Scotland
In Scotland, work associated with thermal insulating material within a wall is listed in schedule 3 of the Building (Scotland) Regulations as work that does not need a building warrant. It must still meet the building standards, so the survey still checks that the wall and the chosen material are suitable, including exposure to wind-driven rain.
Funding in Scotland
- Home Energy Scotland is the starting point for the Home Energy Scotland Grant and Loan and for Warmer Homes Scotland, which can include cavity wall insulation.
- Many councils also run area-based schemes for insulation in particular streets or estates.
- ECO4 runs until 31 December 2026 across Great Britain, including Scotland.

What to know before you choose beads
Polystyrene is combustible, so beads are not the right choice for every building; height, use and nearby openings matter, and the system certificate sets the limits. PVC-sheathed cables in the cavity should be sleeved or kept out of contact with the beads where the certificate requires it. We check both at survey.
What is included
- Certified bonded bead system
- Binder applied at the nozzle
- Making good to the mortar colour
- Cable and opening checks at survey
- Regulations route and guarantee named on the quote
