Why Choose Global Energy Insulation For External Wall Insulation?

How Our EWI System Transforms Your Property

The process begins with securing high-performance insulation boards directly to the external facade of your home, creating a protective thermal envelope. This layer effectively eliminates thermal bridging, which is a primary cause of heat loss in older homes. We then apply a robust, fibre-reinforced base coat to ensure structural integrity. To provide a flawless aesthetic finish, we complete the installation with a high-quality silicone or monocouche render. This weather-resistant finish not only protects your brickwork but also revitalises the exterior appearance of your property.

Could EWI Solve Your Damp and Condensation Problems?

Many residents in older homes around Mountain Ash struggle with persistent black mould and condensation caused by cold walls. External Wall Insulation acts as a thermal shield, keeping your internal walls warm and preventing the moisture buildup that leads to damp issues. By increasing the energy efficiency of your walls, you will notice an immediate difference in comfort levels during the winter months. This is particularly effective for improving your EPC rating, ensuring your property meets modern energy standards and reducing your reliance on expensive heating systems.

Local Compliance and Professional Standards

We understand the nuances of local building regulations and the requirements for energy retrofits in South Wales. Our team operates strictly within the PAS 2035 framework, ensuring that every project is assessed and coordinated to meet national quality benchmarks. By choosing us, you benefit from our status as a SWIGA-backed installer, meaning your investment is protected by comprehensive insurance-backed guarantees. We manage all the technical aspects of the install, ensuring compliance with local planning and building control rules so you can enjoy a stress-free experience.

A Complete Service with Global Energy Insulation

What sets us apart is our holistic approach to home renovation. While we specialise in external thermal upgrades, our sister company, Global Plastering, offers expert traditional plastering services, allowing us to manage your home improvements from the outside in. We are CHAS accredited and fully insured, bringing peace of mind to every commercial and residential project we undertake.

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.
