How Much Insulation Do I Need in My Walls

How Much Insulation Do I Need in My Walls

How much insulation do I need in my walls? If you’re asking yourself this question, then chances are, you’re talking about your cavity walls.

Solid walls do not have a gap between two layers of brickwork, so there is no space for you to insert any material ‘in your walls’.

A cavity wall does contain this gap, which many people like to fill with some form of insulating material in order to boost the thermal qualities of their home.

This process is completed by drilling strategically-placed holes into your exterior walls. A series of hoses are then placed into the holes, and an insulating foam material is sprayed into the gap.

As you can’t see this process taking place behind the brickwork, it is very much a guessing game of how much is required, and if you’ve adequately covered your wall space.

The Best Time to Insulate

For this very reason, it is a lot more effective and a lot cheaper to have wall insulation installed at the very beginning of a building project.

Unsurprisingly, it is a great deal more complicated adding insulation material afterwards, once the building is fully erect.

However, we do realise that not everyone has this luxury, and you more than likely live in a house you didn’t build yourself.

So with this in mind, let’s move on to measurements, and why they matter….


How Much Insulation Do I Need in My Walls?

The general rule of thumb is to use as much insulation as you need to extend from the ceiling, to the floor, without any gaps or cracks in coverage.

How much you will need is hard to tell, and will largely depend on the size of your wall. Again, it’s not easy to tell if your wall is even completely covered, as you’re essentially completing the job blind!

As an absolute minimum, you will need approximately 125mm of high grade insulation to satisfy current building regulations.

Insulating the Gap Has its Problems!

Cavity wall insulation does come with some issues, as first highlighted above, with the blind application process.

Even if completed successfully, this approach to insulating your walls offers a few complications.

Cavity wall insulation is supposed to reduce heat loss through your walls-and it can achieve this in dry, warm and calm conditions.

However, in wet and windy weather, this approach proves to be not so effective. Why?

Placing a material in the gap between your two layers of brickwork means you are effectively installing a bridge for moisture to travel across. Damp masonry acts as a poor thermal insulator and will cause your home to lose energy.

So the solution to a potential problem is actually helping to cause the problem in the first place!


External Cavity Wall Insulation Solves Those Problems!

There is a better alternative to internal cavity wall insulation. How much insulation do I need in my walls? None whatsoever-use external wall insulation instead!

Home Logic Wall Insulation is applied to the external walls of your home. After application, the effects are almost immediate. Once sunken into the brickwork, the product provides an invisible 17mm barrier against water absorption, dirt and debris.

It is effectively like you are wrapping your home up in one big, invisible force-field!

This is a much better alternative to filling the gap in-between your cavity wall (and potentially opening your property up to the presence of moisture and mould). And not only that– you can actually see what you are doing!

Not allowing wetness to affect your masonry means you can prevent over 25% of heat loss through your cavity walls.

Home Logic Wall Insulation prevents water absorption by as much as 95%. These impressive stats add up to provide proof of effectiveness, and overall performance.
