Why upgrade insulation in your attic rooms?

A significant amount of a home's heat is lost through the roof, making room in roof insulation one of the most effective ways to improve your property's thermal performance. By properly insulating these areas, you eliminate cold spots, reduce the risk of condensation and black mould, and create a more comfortable living environment. Whether you live in a traditional Victorian terrace or a more modern property, upgrading your insulation is a smart investment that directly impacts your EPC rating. For landlords in Barry managing HMOs or rental properties, our services are vital for meeting current MEES compliance standards.

How our PAS 2035 accredited process works

Quality is at the core of everything we do. As a PAS 2030 compliant company, we strictly adhere to PAS 2035 retrofit standards for every project. We start with a thorough assessment of your roof structure to identify where heat loss is occurring. Our installers use high-performance, breathable materials to insulate sloping ceilings and tricky corners, addressing thermal bridging issues that standard DIY solutions often miss. Following the installation, our sister company, Global Plastering, provides a professional internal finish, ensuring your room looks as good as it performs.

Room In Roof Insulation FAQs

Frequently Asked Questions

Answers to common questions about our PAS 2030 accredited room in roof insulation, reducing heat loss, and lowering high winter energy bills across South Wales and South West England, Ferndale, and South Wales.

How long does it take to insulate a room in the roof?

+

Most projects are finished within 2 to 4 days, depending on the size of the attic and the complexity of the slopes. Because we handle the plastering through Global Plastering, we keep the timeline tight and avoid the delays that come with waiting for different trades to arrive.

Will I lose a lot of space in my room after insulation?

+

Modern insulation boards are incredibly efficient, which means we can achieve great thermal results with relatively thin materials. You might lose a small amount of space from the walls or ceiling—usually only a few centimetres—but the trade-off in comfort and lower bills makes it a very worthwhile investment.

Can I get help with the costs of insulation in South Wales?

+

There are often government grants or local authority schemes available for energy-efficiency improvements, especially for properties with low EPC ratings or for households meeting certain criteria. As PAS 2035 specialists, we can help you understand what support might be available for your specific home.

What is the difference between loft insulation and room in roof insulation?

+

Standard loft insulation involves laying mineral wool on the floor of an unused attic space. Room in roof insulation is much more detailed; it involves insulating the actual slopes, vertical walls, and flat ceiling of a lived-in space to create a "thermal envelope" around the room itself.

How do I know if my attic room is already insulated?

+

If the room feels significantly colder than the rest of the house, or if you can hear a lot of external noise, it’s likely poorly insulated. We can perform a quick assessment to check the current levels and show you where improvements can be made.
