Walls

External Wall Insulation

For solid block or concrete walls with no cavity, external wall insulation is generally the preferred option. It can also be used in addition to cavity wall insulation to further improve the performance of your external walls. External wall insulation involves wrapping a layer of rigid insulation around your home, fixing it to the walls, embedding mesh in it to provide strength, and covering it in a render to provide weather resistance.

Dryline Internally

Internal wall insulation might be recommended for your home because it has solid or cavity block walls, and external insulation is either not possible (i.e. for some protected structures) or is not considered the best solution.

Internal insulation (sometimes referred to as ‘drylining’) usually involves fixing insulation boards to the inside of the external walls and covering them with a vapour control layer, plasterboard, skim and new painting. As the boards are applied to the inner side of the walls, there will be some loss of space in the rooms.

Pump the cavity with bead insulation- If your home has cavity walls which are not insulated, or only partially insulated, then cavity wall insulation is an easy, cost eﬀective ﬁrst step to reduce heat loss. If your home has a cavity wall, insulation is pumped into the cavity. A series of small holes are drilled in the wall, at regular intervals, on the outside. The insulation is then pumped into the cavity through these holes, and the holes are filled in so that they match the rest of the wall.

Floors

Provide underfloor insulation if you are doing a major renovation

Roofs

Around 25 per cent of heat is lost through the roof of your home. By simply insulating your loft, you will not only be making your home more energy efficient, saving around €130 per year on your energy bills, but you will also make your home warmer and more comfortable to live in as well as doing your bit in reducing green house gases. With ever increasing fuel prices set to rise year after year, you need to act now to combat heat loss.
You can provide additional insulation to the roof between and roof joists
Building regulations stipulate that to meet today's standards your attic should have a minimum of 12 inches (300mm) of insulation. If your attic insulation does not meet these standards and you would like to understand how we can go about helping you get to a higher standard.
Did you know that there are grants available to insulate your attic? See our section on grants here...

You should contact a qualified advisor who will survey your property and let you know what simple measures your property requires to meet the current building regulations and inform you of what grants or discounts are available in your area.
