Is Cavity Wall insulation suitable for me

Do I definitely have a cavity wall?

No. Not all properties have cavity walls. The pictures below show two different types of brick patterns. If all your brick look to have been laid in the same pattern then the odds are that you have some type of cavity. If however every few courses you have a row that look more like you are looking at the end of a brick then this could be an indicator of your external walls being solid.

Understanding the challenges

Can cavity wall insulation cause damp in my property?

Yes, but only if the correct precautions are not taken. As described above, we go to great lengths to ensure that the right conditions are present for a cavity fill before insulating any property.

We can also carry out a “pulse test” to ensure your property isn’t sealed too tight and the moisture build up from day to day living becomes a problem. Where a property is identified as being inadequately ventilated, we will recommend a ventilation strategy to incorporate a controlled means of ventilating the area which will eliminate the possibility of any damp or mould. The adage to look for is “Insulate tight, ventilate right”.

How does Cavity Wall Insulation Work?

Filling the Gap

Cavity wall insulation is all about filling the space or ‘cavity’ between the two layers of a wall. This space is usually filled with air, but by filling it with insulating material, we can slow down the transfer of heat.

Trapping Heat

The insulation material works much like a thermos flask. It traps heat within the walls, keeping the warmth inside your home and the cold outside, or vice versa depending on the season.

Comfortable Indoor Environment

By preventing the loss of heat through your walls, your house can keep a more stable and comfortable temperature.

Reduced Energy Consumption

As your home retains heat better, you’ll use less energy to keep it warm, saving on energy costs and helping the environment by reducing carbon emissions.

Site Assessment

Initially, a surveyor conducts an onsite assessment of your wall cavity, employing a borescope—a tool with a camera—to gauge cavity depth, existing insulation status, and detect any debris within the cavity.

Existing Insulation Removal

Existing insulation must be removed before any new insulation can be installed. This prevents a ‘thermal bridge’ from being created that could lead to dampness in your home. It’s also important any debris within the cavity is cleared for the same reason.

Your Proposal

We will drill holes of roughly 22mm in diameter along the outer wall of the property to allow us to inject the insulation into the cavity. These holes are drilled on the seam of mortar to ensure that when the process is complete and the holes are filled the visibility of them is kept to a minimum. Once installed, the insulation will help your home to retain heat.
