Ceiling, Wall & Underfloor Insulation

J H Brewster Ltd can supply your insulation requirements. Even homes built 10 years ago could have insulation which does not meet the current Building Code Requirement due to the standard being raised over the whole country.

Benefits of Insulation

  • A fully insulated house needs about half of the heating of an un-insulated house.
  • An un-insulated roof can have heat loss of approximately 42% (older homes up to 60%).
  • Correct insulation in the ceiling also benefits in the summer months helping to keep the house cooler.
  • Better insulation means a warmer, drier and healthier environment and is especially important for people with respiratory illness or other conditions brought on by living in cold, damp houses.

Different options available:

  • Ceiling (segment or blanket)
  • Walls (segment)
  • Underfloor (semi-rigid segment or blanket)
