External Insulation

External Insulation at RT Plastering Services

Keeping your property energy efficient, warm and attractive

RT Plastering Services are specialists in providing External Wall Insulation Systems or EWIS. Materials used range from expanded polystyrene, mineral wool, polyurethane foam or phenolic foam together with a reinforced cement based mineral or synthetic finish.

It is estimated that 45-50% of your property heat is lost through uninsulated solid walls. That means lots of wasted energy and money on heating costs – almost twice as much as a traditionally built property with an un-insulated cavity!

By insulating your walls from the outside, you will stop the heat from escaping and keep your home warmer. By doing that, you will save money on your heating costs and lower your home’s carbon footprint.

What are the benefits of External Wall Insulation ?

Applying External Wall Insulation to walls is one of the most effective ways of improving the energy efficiency of your home.

External Wall Insulation (EWI) acts like a protective shell around your home, shielding the property from the elements and retaining the warmth inside.

Cavity Wall Insulation at RT Plastering Services

Cavity walls are made of two layers with a small gap or ‘cavity’ between them. Solid walls have no gap, so they let more heat through.

Another way to tell is by measuring the width of the wall. Look at an external wall window or door and if the brick wall is less than 260mm, then it is likely a solid wall, while if it is greater, it is probably a cavity wall.

If you live in a house that is not made from bricks, such as a steel or timber-framed building, insulating will be different.

Solid Wall Insulation at RT Plastering Services

Insulating your solid walls could cut your heating costs considerably, because solid walls let through twice as much heat as cavity walls do. The good news is they can be insulated. If your home was built before 1919, its external walls are probably solid rather than cavity walls.

Solid walls can be insulated – either from the inside or the outside. This will cost more than insulating a standard cavity wall, but the savings on your heating bills will be bigger too.

How much would you save by insulating your solid walls?
