Internal Wall Insulation

Improving wall insulation is an excellent way to make long-term savings and improve the heat and comfort levels of your home. There are three main methods of wall insulation, depending on the type of wall and the type of house: Cavity Fill, Internal and External. Cavity walls are made of two layers with a small gap or cavity between them. Solid walls have no such gap, for solid walls insulation must be applied either internally or externally.

What is Internal Wall Insulation?

Internal wall insulation involves fixing a layer of rigid insulation to the inside of external walls, usually with a plasterboard finish. This is also referred to as dry-lining. An ideal opportunity to install internal insulation is when other work is already required, e.g. when existing plaster work is poor or if you are considering renovating or decorating your existing rooms. This is because internal wall insulation is finished with a new layer of plasterwork creating perfect wall surfaces for you to decorate as desired.

Some electrical fittings, wardrobes, skirting boards may need to be removed temporarily for the walls to be insulated but they are re-fitted when the insulation works are completed by our expert fitters. We understand that the home needs to remain functional during works being completed. Where possible we recommend a room by room approach which means only one room will be unusable at a time.

What are the Main Benefits of Internal Wall Insulation?

Internal Wall Insulation creates an insulation envelope around the home. Because the heat can no longer escape through the walls, it is reflected back into the living areas, creating a constant warm home. It has various advantages which include improving the airtightness of a home (i.e. elimination of unwanted draughts through the building fabric), as well as substantially increasing the thermal performance of a dwelling.

With up to 35% heat lost through walls, internal wall insulation can reduce your heating bills significantly. It can also reduce your carbon footprint by cutting your CO2 emissions by up to 2.5 tonnes per year.

What are Typical Costs of Internal Wall Insulation?

Typical cost of internal wall insulation for a 3 bed semi-detached house is €7,000 and there is a SEAI grant of up to €2,400 (terms and conditions apply)

With a variety of grants available from The Sustainable Energy Authority of Ireland to assist towards the cost of insulation for houses built prior to 2006, it is a good idea to take advantage of this benefit as soon as possible.

Process

  • One of our insulation surveyors will visit your property to complete a thorough survey in order to prepare an accurate specification for your property. The surveyor will also look at the suitability of your rooms for internal wall insulation and discuss the various options available.
  • The surveyor will provide a detailed quote for carrying out the work as well as inform you of any grants that you may be entitled to.
  • A convenient time for the work to be carried out will be agreed with you.
  • The walls to be insulated and the surrounding area must be completely cleared of any fixings or pictures.
  • The specified internal wall insulation is fixed to the walls.
  • Plasterboard is installed and the walls are skimmed.
  • Any fixtures removed at the beginning of the process are reinstated by qualified carpenters, plumbers and electricians.
  • The walls are now ready for decoration.
  • You can now enjoy newly insulated and decorated rooms in a more comfortable and energy efficient home.
