Guide to home energy upgrades

Learn about the home energy upgrades available to transform the comfort levels of your home and reduce your energy bills.

Comfort

Enjoy a warmer, cosier and healthier home by upgrading your insulation and adding renewables.

Savings

Save on energy bills by using less energy and adding renewable energy to your home.

Environment

Reduce your emissions and your carbon footprint with an energy efficient, B2 home.

Why invest in insulation?

It makes financial sense to start your home energy upgrade with insulation. Otherwise you’re paying to heat your home, only to lose it through attics, walls, windows and doors.

Insulating your home helps to:

  • Reduce your heating bills by improving your energy efficiency
  • Increase your home comfort levels
  • Reduce your impact on climate change by using less energy to heat your home

Did you know?

Along with keeping your home warmer, a well-insulated home helps you get the most from other future upgrades. There are different types of insulation to choose from, depending on the needs of your home.

Attic and rafter insulation

Attic and rafter insulation is generally the most cost effective home energy upgrade. As heat rises, you can lose up to 30% of your home’s heat through the roof. Even if you already have insulation in your roof, you may still be losing heat if it’s damaged, installed incorrectly or there’s not enough.

With attic and rafter insulation, you can see significant savings on heating bills. Depending on how you use your attic, you can prevent heat loss by insulating at ceiling or rafter level.

Ceiling level insulation

If you only use your attic for storage, then it makes sense to insulate it at ceiling level. This means the heat is kept in the rooms below and the attic stays cold. To do this, your contractor will roll a thick layer of insulating material over the attic floor. They will insulate the water tank and pipework to make sure they stay warm. They’ll also provide a walkway and ventilation. The ideal thickness of attic insulation is 300mm.

Rafter level insulation

If you use your attic space as a habitable room, then you can insulate at rafter level. This applies to both sloping ceilings and flat roofs. It is usually done with a rigid insulation product.

When insulating an attic, it’s important to ensure that proper ventilation is installed. Ventilation prevents moisture build up that could damage your roof structure. Use an SEAI registered contractor for peace of mind that the upgrade is done correctly.
