Attic Insulation Dublin

We provide a very affordable insulation service for attics in Dublin. Wide range of insulation options to choose from, all expertly installed by our attic insulation specialists. Free estimates.


The attic is one of the most important areas of a house to have effective insulation. Heat has a natural tendency to rise and will therefore escape out through ceilings if allowed. It is estimated that a house can lose 35-40% of its heat through the attic roof.

Most houses in Ireland only have a thin layer of fibreglass attic insulation that is insufficient to retain the heat from below. With a large percentage of that heat escaping, the heating must be kept on longer to retain a comfortable temperature in the home. A well-insulated home can save up to €450 per year by upgrading the insulation in the attic area.

Dublin Roof Care can prevent heat loss by upgrading attic insulation in new and existing houses. Our experienced team can update homes to the highest standard. Using Rockwool Rockprime Blown Insulation and Knauf Insulation Mineral Wool, the attic area is covered with a 250 mm-300 mm layer of high-quality attic insulation. This will help prevent the heat from escaping, keeping the house warmer and less prone to drafts.

Rockwool Rockprime Blown Attic Insulation

Rockwool is a high-quality and high-performance insulating product. Rockwool is a very durable product made from rock and will not decrease in depth over time. As this product is pumped into attic spaces, it can fill every possible void or gap allowing no heat to escape. Rockwool is quicker to install than traditional attic insulation products, with little disturbance to the home. Our team always follows the required steps to provide the highest quality attic insulation to homes

Knauf Ecose Mineral Wool Insulation

Knauf Ecose Mineral Wool is a newly developed product that provides the highest standard of insulation without the itchiness of conventional fibreglass products. The layers of Knauf Mineral Wool is rolled out in the attic space between the joists and over the joists. Knauf Mineral Wool comes available in the depths of 200mm, 150mm and 100mm and it can be installed to the desirable level. If no insulation exists and more than 200mm is needed, we then use two layers of insulation to ensure a proper covering.

Here are some of the steps our team will follow when using insulation:

  • Our team will examine the attic space and decide on the insulation level needed. We normally recommend that the attic insulation be brought up to 300mm. If 100mm of fibreglass is already in the attic, we will roll over this insulation to give a further 200mm.
  • Our team will roll out one layer (if no insulation already exists) between the timber joists on the floor of the attic area. These are to be tightly fitted in place between the timbers.
  • We then use another layer of mineral wool over the timber joists bringing the level of insulation up to 300mm depth.
  • Insulating tank jackets and covers are fitted to the water tanks in the attic to help protect from freezing in cold conditions. Pipe lagging is also added to protect the pipes from freezing.
