What we look for in Thornaby-on-Tees
We cover Thornaby-on-Tees and nearby Stockton-on-Tees, Billingham and Middlesbrough. Thornaby-on-Tees sits around 41 miles from York. Yorkshire's housing includes stone and brick terraces, back-to-backs in parts of West Yorkshire, and post-war estates with steel-framed and concrete house types.
Exposure to wind-driven rain varies across North Yorkshire: sheltered town streets fare better than walls on high ground or facing the prevailing weather, and the render, beads and cill details are chosen with that in mind.
For terraced homes in Thornaby-on-Tees with attractive brick fronts, one approach is to insulate the front internally and the rear externally.

England: planning and regulations
Internal insulation rarely needs planning permission, but in England and Wales insulating or replastering more than half of a wall's area involves building control, and listed buildings need consent for internal changes that affect their character.
What are the options for internal insulation?
- Insulated plasterboard — PIR or phenolic foam bonded to plasterboard, fixed to the wall and skimmed. Thinnest option.
- Insulated stud wall — a timber or metal frame filled with insulation, with a vapour control layer and plasterboard. Takes more space but runs services easily.
- Wood fibre and lime — breathable boards finished in lime plaster, for older walls that need to manage moisture.
