Why have new Internal Wall Insulation?

Save on Your Energy Bills

By insulating your internal walls, you can significantly reduce heat loss and improve your home’s overall energy efficiency helping you save money on heating costs throughout the year.

Quick & Hassle-Free Installation

Internal Wall Insulation can be installed with minimal disruption. Our trained professionals complete the work quickly and cleanly, allowing you to enjoy a warmer, more efficient home without major mess or inconvenience.

Year-Round Comfort

Internal Wall Insulation keeps your home warmer in the winter and cooler in the summer. By reducing drafts and heat loss, it helps maintain a consistent temperature and a more comfortable living environment all year round.

Installation Process Step-by-Step

1. Assessment – One of four qualified surveyors assesses your property to identify wall types, check their condition, and confirm suitability for internal wall insulation.

2. Preparation – Radiators, sockets, and fittings are carefully removed from the walls to be insulated. Any damp or structural issues are resolved before installation begins.

3. Installing Insulation Boards – High-performance insulation boards are securely fixed to your internal walls using adhesive or timber battens to create a strong, even surface.

4. Sealing & Airtightness – All joints, edges, and gaps are sealed to stop draughts and form a complete thermal barrier across the wall.

5. Plasterboard Finish – A layer of plasterboard is applied over the insulation, ready to be skimmed, painted, or decorated just like a standard wall.

6. Reinstating Fixtures – Radiators, switches, and other fittings are neatly refitted once the walls are finished.

7. All Done! Your home is now fully insulated from the inside, providing lasting warmth, improved energy efficiency, and enhanced comfort all year round.
