Frequently Asked Questions

Please reach us at enquiries@coastalprimeltd.co.uk if you cannot find an answer to your question.

The best type of insulation for your home depends on several factors such as the size of your space, your budget, and your insulation needs. Our team can help you determine the best insulation option for your home.


Insulation can last for many years if it is installed properly and maintained. However, the lifespan of insulation can also depend on factors such as moisture, pests, and wear and tear.


We provide a comprehensive range of insulation solutions, including:

  • General insulation
  • SuperQuilt reflective foil insulation
  • Cavity wall extraction and injection
  • Room-in-Roof solutions
  • Foam extractions and replacement


SuperQuilt is a multi-layer reflective foil that acts as a radiant heat barrier, vapour control layer, and insulator all in one. It's slim, easy to install, and highly effective, reflecting heat in summer and retaining warmth in winter. Ideal for both new builds and renovations.
