Warm Your Home from the Top Down

Up to 30% of your home’s heat is lost through the roof. Loft insulation is a fast, affordable upgrade that locks in warmth and slashes heating costs — with minimal disruption.

What is Loft Insulation?

Loft (or attic) insulation involves installing layers of insulating material in your roof space to stop heat rising and escaping.

We offer cold Loft Insulation (insulating the attic floor).

*Please note we install Attic Insulation only when required as part of a complete External Wall Insulation upgrade for your home and not as a stand alone measure.

Key Benefits of Loft Insulation?

Reduced heat loss = warmer rooms below

  • I recently had my house wrapped by BlueBuild, and the entire experience was smooth from start to finish. My first point of contact was David, the project coordinator, who organised everything efficiently and kept the process running seamlessly. Different members of the team came by throughout the project to get things moving, and everyone was professional, friendly, and considerate. They always called in advance to make sure I was at home before arriving. Although this type of work can be quite messy, I was pleasantly surprised by how clean they kept both the inside and outside of the house throughout the job. They made a real effort to minimise disruption at every stage. Once all the preparation work was completed, John and his team arrived to carry out the wrapping. There were five people working incredibly hard, even on a Saturday, and their work ethic was outstanding. They worked nonstop and always made sure the areas were left as clean and tidy as possible before leaving each evening, even when they were returning the next day. On the final day, the team went above and beyond, cleaning the windows, blowing away dust, wiping down surfaces, and even covering the skip with plastic to ensure nothing could blow out before collection. The attention to detail and professionalism really stood out to me. I’m absolutely delighted with the finished result and the smooth overall experience. I would definitely use BlueBuild again, and I’m already speaking with them about solar panels. Without hesitation, I’ll be choosing the same company for that project too.
