Why Choose Our Loft Insulation Services in South Wales?

Why choose professional loft insulation for your home

Standard, thin, or damaged insulation often fails to keep pace with modern thermal requirements. By opting for a professional upgrade, you are not just laying material in a roof space; you are investing in a comprehensive heat loss solution. Our technicians assess your loft for existing issues such as damp, ventilation restrictions, or material degradation. From simple top-up insulation to complete removal and replacement of outdated materials, we ensure your home is optimised for the local climate. Proper insulation acts as a barrier, keeping your house cool in the summer and warm throughout the winter months.

How does our PAS 2035 accredited process work

We take a systematic approach to energy efficiency, adhering strictly to PAS 2035 retrofit standards. This ensures that every installation is safe, compliant, and tailored to the specific building physics of your property. Our process begins with a detailed survey where we assess your roof structure, evaluate current thermal performance, and identify any risk of interstitial condensation. Following this, we install high-quality insulation materials using techniques that meet PAS 2030 accreditation criteria. By focusing on whole-house performance, we ensure our work contributes positively to your property's EPC rating and provides genuine long-term value.

Supporting properties across Blaenau Gwent and beyond

Whether you are a private homeowner or a landlord managing multiple properties, we provide reliable insulation services across Abertyleri and within a 35-mile radius. We are well-versed in the challenges faced by older housing stock in South Wales, including the complexities of solid walls and roof spaces in period properties. Our team is fully insured, carries all necessary licenses as waste carriers, and maintains rigorous health and safety standards through our CHAS accreditation. We treat every home with the care it deserves, minimising disruption while delivering a professional, clean, and efficient installation.

Frequently asked questions about roof insulation

Many residents ask if their existing insulation is sufficient. Often, older properties have compressed or missing materials that no longer provide a thermal barrier. Another common concern involves the impact on property value; yes, improving your EPC rating through professional insulation is a proven way to increase the attractiveness of your home in the current property market. As SWIGA members, we provide added confidence through insurance-backed guarantees for eligible work. If you have concerns about high energy bills or cold spots in your ceiling, get in touch with our team today to schedule your assessment on 07393 355531.

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.
