Insulation in all its forms is a proven way to lower your heating costs, increase your energy efficiency and add value to your property.
However, more than 70% of Irish homes are either uninsulated or inadequately insulated, leading to heat loss on a significant scale. For example:
- Up to 35% of heat can be lost through an uninsulated or poorly insulated attic
- Up to 30% of heat can be lost through uninsulated or poorly insulated walls
- Up to 10% of heat can be lost through floors
- Up to 15% of heat can be lost through windows

Installing or upgrading insulation then is a wise investment in your home, and an investment that will soon be paying for itself. For example:
- Proper attic insulation in a typical house will save approximately €140 per year, so that the insulation pays for itself in three years.
- Cavity wall insulation will save between €100 and €160 per year, typically paying for itself in five to seven years.
Even better news is that for any pre-2006 home, the Government will provide cash grants through the Better Energy Home scheme to assist your insulation retro-fitting.
The sooner you insulate the sooner you will start feeling the savings, along with the comfort of a warmer and cosier home.
Your home’s BER Rating will also improve, adding value to your home.

Donegal Town Hardware – Insulation Experts
Here at Donegal Town Hardware we have years of experience in dealing with retro-fitting existing homes and insulating new builds. We can advise on and provide the materials for all of your insulation needs.
We deal with all major insulation suppliers like Kingspan, Quinntherm, Knauf, Rockwool and Superquilt, who have a wide range of thicknesses, lengths and specifications for all kinds of house design and specified BER ratings.
These include rigid insulation slabs for concrete floors and for cutting between rafters; Knauf Earthwool glass fibre or Rockwool quilts for laying above and between floorboards in suspended timber flooring and between timber stud partitions, and insulated plasterboard for drylining your home.
In keeping with the changes to the building regulation, we also provide and can advise on a wide range of draught sealing and Air Tightness products, from Ecological Building Supplies, such as the Intello Plus Intelligent vapour check membrane, Tescon and Contega Tapes and Orcon flexible Mastic, to ensure that there are no hidden spaces through which your heat is escaping. If you have drafts, you are losing expensive heat.
As part of our every expanding range of products, we also stock Quinnlite Thermally efficient blocks, which eliminates the problems with thermal bridging at the junction between the ground floor slab and the innerleaf.
At Donegal Town Hardware we can help you with everything you’ll need to ensure your insulation work runs as smoothly as possible and with the most effective results.
We are experts in our field and can liaise with the insulation providers to have calculations done to establish the requirements of any given property to achieve a specific BER rating.
