Internal Wall Insulation

Transform your home’s energy efficiency from the inside out. Internal wall insulation drastically reduces heat loss, eliminates draughts, and creates a warmer, more comfortable living space without altering your home’s exterior.

Insulation

What Is Internal Wall Insulation?

Often referred to as “dry lining,” internal wall insulation involves fixing rigid insulation boards to the inner surfaces of your home’s external walls. This creates a highly effective thermal barrier that stops your expensive heating from escaping through the cold masonry, keeping the warmth locked inside where it belongs.

Installation Process

Precision Dry Lining Technology

Our skilled technicians install premium, insulated plasterboard directly onto the inner face of your external walls. Depending on the condition and type of your existing walls, these boards are either mechanically fixed to timber battens or bonded directly to the masonry to ensure a secure, continuous thermal layer.

A Flawless, Ready-to-Decorate Finish

Once the insulation boards are securely in place, the entire surface is professionally skimmed with plaster. This leaves you with perfectly smooth, brand-new interior walls that are ready for painting or wallpapering as soon as they dry, instantly modernizing your living space while upgrading its energy performance.
