Why Choose Our Loft Insulation Services in South Wales?

Why is proper loft insulation critical for your home?

Heat rises, and without adequate insulation, up to 25 percent of your property heat can escape through the roof. This leads to cold draughts, uneven room temperatures, and unnecessarily high energy bills. By upgrading your insulation, you create a more stable indoor climate and effectively reduce your carbon footprint. Our retrofit assessments identify exactly where heat loss occurs, allowing us to implement the most effective thermal solution for your specific building type.

Tailored solutions for every property type

Every home has unique requirements, which is why we offer a range of solutions including top-up mineral wool, high-performance insulation boards, and room-in-roof conversions. For older homes in Abercarn with limited space, we use precision techniques to maintain ventilation while maximising thermal retention. We also specialise in full loft boarding and structural upgrades to meet modern PAS 2035 retrofit standards, ensuring your renovation adds genuine value and comfort to your property.

The Global Plastering installation process

Our service begins with a comprehensive retrofit assessment to evaluate your current EPC rating and identify areas for improvement. Once we establish the best strategy for your loft, our professional team carries out the installation with minimal disruption to your daily life. We manage every aspect of the project, ensuring all works are fully compliant with current safety and building regulations. Our focus is on precision, cleanliness, and long-term performance, giving you complete peace of mind.

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!"

Loft Insulation FAQs

Frequently Asked Questions

Answers to common questions about our PAS 2030 accredited loft insulation services. Discover how we eliminate draughts, reduce heat loss, and improve EPC ratings across South Wales and South West England, South Wales, and South West England.

How thick should my loft insulation be to save money?

+

To meet current UK building regulations and get the best results for your energy bills, we recommend a total thickness of 270mm. If you already have some insulation but it's thin or old, we can "top it up" to reach this standard, which makes a massive difference to heat loss reduction.

Can I still use my loft for storage after it is insulated?

+

Yes, but you shouldn't squash the insulation down with boxes, as this stops it from working. We can install loft legs or a raised boarding system. This allows the insulation to sit at the full 270mm depth while giving you a sturdy, flat platform for your belongings.

How long does it take to install?

+

For most standard homes, like a three-bedroom semi-detached in Ferndale, we can usually finish the job in just a few hours. It is one of the least invasive home improvements you can do, and we make sure all mess is cleared away before we leave.

Will loft insulation cause damp or condensation?

+

Only if it is installed poorly. We make sure that your roof eaves are kept clear so that air can still flow through the loft space. This is why professional installation is so important—we balance thermal comfort with proper ventilation to protect your roof timbers from rot.

Is there help available for the cost of insulation?

+

There are often various grants and schemes available, such as ECO4, particularly for low-income households or properties with low EPC ratings. As PAS 2030 accredited installers, we stay up to date with these schemes and can advise you on whether your project might qualify for funding.
