How does our attic insulation process improve your home?

Our expert team follows a rigorous, PAS 2030 compliant process to ensure your loft room is properly protected against heat loss. We focus on the areas where thermal bridging most frequently occurs, including sloping ceilings, stud walls, and vulnerable gable ends. By installing high-performance insulation materials within these spaces, we ensure that warmth is retained during the winter and reflected during the summer. This methodical approach is particularly effective for older character properties such as Victorian terraces or detached homes common across South Wales, where uninsulated roof spaces are a primary source of draughts and high heating costs.

Why is room in roof insulation essential for energy efficiency?

For many homeowners in Mountain Ash and Aberpennar, the loft room is often the least energy-efficient part of the house. Beyond the obvious benefit of a more comfortable living environment, upgrading your insulation is one of the most impactful ways to improve your property's EPC rating. Higher energy efficiency not only lowers your monthly utility bills but also adds long-term value to your home. Whether you are aiming to meet current MEES regulations as a landlord or simply wish to create a more sustainable living space, our tailored insulation solutions provide the thermal performance required for modern comfort.

What Our Clients Say About Global Plastering

"Excellent work the team removing our old 1970's cladding and replacing it with insulation and a rendered finish. The job went smooth from start to finish with all old materials removed from site. We are very pleased with the end result and would thoroughly recommend Global Plastering."

A. Jenkins (Ferndale)

"Dilwyn and his team were brilliant and made a lovely job of our EWI. They were very friendly, hard-working, and left no mess at the end of each day. Our house looks great and we can definitely feel the benefits of the insulation already. I'm very glad we chose EWI especially with energy costs as they are now."

G. Toogood (Bristol)

"Charlotte and the team were professional, reliable, and excellent at communicating throughout. They did a fantastic job of skimming and rendering the back of our house during our renovation. Superb quality of work and highly recommended!"

FAQ

Frequently Asked Questions

Answers to common questions about our PAS 2030 accredited room in roof insulation, EPC rating improvements, and energy efficiency retrofit services in South Wales and South West England and across South Wales.

How long does it take to insulate an attic room?

+

Most domestic projects in Ferndale take between 3 to 5 days. This includes the installation of the insulation boards, plasterboarding, and the final skimming. We work efficiently to make sure your home is back to normal as quickly as possible.

Will I lose a lot of space in my bedroom?

+

We use high-performance PIR boards which are much thinner than traditional wool insulation but offer better thermal resistance. You will typically lose about 50mm to 75mm of space on the walls and ceilings. Most customers find this loss is barely noticeable compared to the massive improvement in warmth.

Does this help with damp and mould?

+

Yes, if your damp issues are caused by condensation. Cold walls in attic rooms often attract moisture, which leads to black mould. By insulating the walls, we raise the surface temperature, which stops water vapour from turning into liquid. We also ensure that your roof continues to breathe correctly to prevent any structural timber issues.

Is there a lot of mess during the installation?

+

Insulation and plastering can be dusty, but we take great care to protect your home. We use heavy-duty drop cloths and dust sheets on all walkways and furniture. As licensed waste carriers, we also make sure all old materials and offcuts are removed from your property and disposed of legally.

Can I get a grant for this work?

+

There are various schemes like ECO4 or the Great British Insulation Scheme that sometimes cover room-in-roof insulation depending on your circumstances and your property’s current EPC rating. We can discuss your eligibility during our initial survey and point you in the right direction.
