Do You Know What Your Wall Cavity Is?

A cavity wall is a wall in your property that consists of spacing in between another wall. For example, the exterior wall of your house may be a cavity wall, two walls separated by a gap. Due to the gap, if it is not insulated correctly, you can lose a large amount of heat through your home's exterior wall.

This is a relatively modern form of construction for residential and commercial properties. Traditionally walls were singular and could not be insulated as well as a cavity wall.

Using suitable materials such as mineral wool, spray foam and other insulation types, our team at Safe Energy World are experts at ensuring your external wall is adequately insulated.

How Does Cavity Wall Insulation Works?

Cavity wall insulation fills the gap between the two walls allowing for a more insulated, soundproof and robust structure. Insulants such as spray foam can be used to fill your wall cavity.


Why Do You Need Cavity Wall Insulation?

Insulating your cavity walls is essential for every home, residential, and commercial property.

Many benefits and reasons show the importance of insulating your cavity walls.

  • Non-Insulation

  • Modern builds most likely have cavity walls, and by not having them professionally insulated, your home will unnecessarily lose heat, costing more energy bills.

    You will experience a lot more discomfort than you should. Non-insulation can cause unwanted issues that can be quickly resolved.


  • Added Value

  • If your home has insulated cavity walls, using insulation that lasts the lifespan of a property, you are essentially adding value to your home.

    Because insulated cavity walls have many benefits for homes, buildings and homeowners, you can add value to your property by having them insulated.


  • Utilise Space

  • By having a cavity in between your external walls, you have a space that should be filled and can be filled for added benefits.

    By effectively utilising this space, your cavity, you can keep the warmth in your home, reduce sound pollution, save money on energy bills every month and a lot more benefits from it.


  • Prevent Mould

  • Cavity wall insulation can prevent the passing of water, toxins, pollutants and other nasty surprises. Due to the cell composition of certain insulations such as spray foam, your home or commercial property can prevent mould growth. Insulation keeps your property healthy for longer and requires less maintenance.

    Our experts most recommend insulant for filling your cavity wall would be spray foam insulation; it is an incredibly versatile and malleable material.

    Foam insulant also has one of the most superior thermal properties (mainly closed-cell foam) and can help you save up to 35% on your monthly energy bills. Additionally, open-cell spray foam handles sound absorption well and is one of the best insulants for handling noise pollution on the market today.

    EPS Beading Cavity Wall Insulation

    Are You Looking For EPS Beading Insulation?

    Secondly, EPS Beading can provide insulation to your cavity walls at a high level. This insulation strictly applies to cavity walls and is more traditional than spray foam, yet still an advanced and effective solution.

    EPS Beading involves injecting beads into the cavity of your wall, beads which last the lifespan of your property. If you use an EPS Beading solution, installing the traditional cavity boards to fit the insulant is unnecessary, saving time and money.
