Why Choose Global Energy Insulation For External Wall Insulation?

How Our EWI Process Works

Our installation process is designed to be as seamless as possible while ensuring the highest standards of quality. We begin by attaching durable, high-performance insulation boards directly to the exterior of your property, which effectively eliminates thermal bridging. Once the boards are securely fixed, we apply a reinforced base coat to provide structural integrity and impact resistance. The final layer is a high-quality silicone, monocouche, or K Rend finish, which provides a beautiful, weather-resistant aesthetic that protects your home from the harsh Welsh elements.

Improving Energy Efficiency and EPC Ratings

For landlords in Rhondda managing HMOs or rental properties, improving your EPC rating is no longer optional under current MEES regulations. External wall insulation is one of the most effective ways to upgrade an older home, moving it from an energy-inefficient rating to one that is compliant and attractive to tenants. By choosing our whole-house retrofit approach, you are not just reducing your carbon footprint; you are making a smart financial investment that significantly lowers monthly heating costs and protects your building fabric against condensation and black mould.

Are Our Insulation Services Suitable for Your Property?

We have extensive experience working with the diverse housing stock found throughout South Wales. Whether you live in a classic Victorian terrace, a post-war semi-detached home, or a non-traditional build such as a Wimpey no-fines property, our team possesses the technical expertise to deliver results. We are well-versed in the specific building regulations required for solid wall insulation and can handle local authority requirements for conservation areas or period properties. Our PAS 2035 retrofit coordination support ensures that every project is assessed correctly and managed in line with the latest UK standards.

Why Choose Global Energy Insulation?

When you choose us, you are partnering with a locally-based, CHAS accredited firm that prioritises quality and transparency. We offer SWIGA-backed insurance guarantees, giving you complete peace of mind that your home is protected for years to come. Furthermore, we work closely with our sister company, Global Plastering, to provide a true end-to-end service, covering both external insulation and any necessary internal finishing touches. As a company registered in the UK (Company No: 05875199), we are fully insured and committed to serving the Rhondda and surrounding communities with honesty and professional skill.

External Wall Insulation FAQs

Frequently Asked Questions

Answers to common questions about our PAS 2030 accredited external wall insulation, EPC improvements, and heat loss reduction services in South Wales and South West England.

Do I need planning permission for external wall insulation in Ferndale?

+

In many cases, EWI falls under "permitted development," but it depends on the property. If you live in a conservation area or if the insulation significantly changes the look of your house compared to your neighbours, you might need to check with Rhondda Cynon Taf council. We can help you understand the local requirements before we start.

How long does the installation take?

+

For a standard semi-detached or terraced home, the process usually takes between 2 to 3 weeks, depending on the weather. Because all the work happens outside, there is very little disruption to your daily life.

Will EWI solve my mould problems?

+

Yes. Most mould in UK homes is caused by "cold spots" on walls where moisture in the air turns into condensation. By insulating the outside of the building, those walls stay warm, preventing the conditions that allow mould to grow.

Can I get a guarantee for the work?

+

Absolutely. We provide SWIGA-backed guarantees, which are industry-recognised and often required by mortgage lenders. This gives you long-term protection and confidence in the quality of our work.
