Wall insulation options

What kind of wall insulation should I choose?

To insulate the walls of their home, owners may have a choice of:

• cavity wall insulation
• internal insulation
• external insulation

depending on the construction of their home. Homeowners should seek professional advice on which option is most suitable for their home.

Cavity Wall Insulation

Where a house has a suitable cavity, then cavity wall insulation is the most economical investment.

Where this is not possible the options are either internal dry lining or external insulation.

Internal Dry Lining

Internal dry lining, while considerably less expensive than external insulation, will ultimately reduce somewhat the internal habitable space of the home and may not be practical where there is decorative internal plasterwork.

External Wall Insulation

External wall insulation may prove preferable where a significant upgrade to the external facade is already envisaged. Both may result in additional works in order to reinstate electrical, plumbing and glazing fixtures.
