Internal wall insulation is an ideal solution for properties where external wall insulation is not permitted or practical, such as homes in conservation areas or those with specific exterior finishes. By applying high-quality insulation boards to the interior side of your external walls, we create a thermal barrier that stops cold air from penetrating and prevents heat from escaping. This process is highly effective at eliminating cold spots and condensation, creating a more comfortable living environment for you and your family.

We follow the rigorous PAS 2035 whole-house retrofit standards to ensure every installation is safe and compliant. Our process begins with a detailed retrofit assessment to identify the unique needs of your property. We then install premium PIR insulation boards combined with a vapour control layer to manage moisture and airflow effectively. By working to these strict UK building regulations, we guarantee that your energy efficiency improvements are both effective and long-lasting.

What sets us apart is our seamless, professional approach to home improvements. While Global Energy Insulation handles the technical installation and retrofit coordination, our sister company, Global Plastering, completes the project with a high-quality skim finish. This means you receive a full end-to-end service, saving you the stress of hiring multiple contractors. We are SWIGA-backed, CHAS accredited, and fully insured, ensuring total peace of mind for every project we undertake in Ystradgynlais and beyond.

Many of our clients ask how long the installation process takes and whether it will disrupt their daily life; our experienced team works efficiently to minimise any inconvenience. Regarding costs, we provide transparent, no-obligation quotes tailored to your specific property type, whether it is a traditional stone cottage or a more modern build. We also help landlords navigate MEES compliance to ensure rental properties reach the required energy standards.
