Uninsulated buildings may lose up to a quarter of their heat through attic and roof spaces1. ROCKWOOL loft insulation helps to reduce this.

Our range is made from premium stone wool, providing a cost-effective and energy-efficient solution to maintaining consistent temperatures.

Learn all about it – and discover which ROCKWOOL product is right for your new build or  renovation project.

Why do we need loft insulation?

As heat normally rises, uninsulated lofts and attics are prime places where it can escape from a building. Cold air can also easily enter. 

The short-term solution? Turn up the heat in the winter – and put the aircon on in the summer. 

However, this wastes a lot of energy and leads to bigger heating and electric bills – as well as having a negative impact on the environment.

Installing loft insulation in the loft space, both between and over the joists, can combat this - helping keeping the heat in and the cold out. 

 

Premium stone wool insulation helps to:

  • Make buildings more energy efficient
  • Keep homes warmer during winter and cooler during summer 
  • Improve a building’s carbon footprint


High quality ROCKWOOL stone wool can last the lifetime of a building 2 3, passing on the savings to the people who live and work in those spaces for decades to come.

Through the relative high density and volume in combination with the closed layer, ROCKWOOL loft insulation also improves the acoustic performance of the floor – reducing external sounds coming into your sleeping room and providing peace of mind.
The intrinsic good fire performance and high fire resistance will further set your mind at ease.

The effect of the installation can be felt immediately. No more cold draughts through cracks in the ceiling, or the uncomfortable feeling of a cold surface.

FAQs

FAQs

How long does loft insulation last?

ROCKWOOL products are designed to last the entire lifespan of a building. Stone wool material won’t decay and will perform for the lifetime of the building. 12 13

What is the thermal requirement for loft insulation?

The recommended thickness is between 270 and 300mm, according to UK building regulations. This baseline is designed to help reduce energy bills and raise energy efficiency in buildings. 14

Is roll insulation better than blown?

Rolled insulation and blown insulation suit different building needs. Rolled insulation can be more suitable when there is space to roll out the batts. Blown insulation can be helpful for coverage in hard-to-reach attic spaces.
