What are the different types of wall insulation in the UK?

There is a wide range of different wall insulation types in the UK; here are the main ones you can choose from:

Cavity wall insulation

Small holes are drilled in the external walls, and insulation material is blown into the cavity using a special machine. The holes are then sealed with mortar to stop moisture from entering the cavity, making sure your new insulation stands the test of time.

Internal wall insulation

This involves packing the spaces between your internal wall joists with high-quality insulation. Many different types of insulation can be used, including recycled paper mulch, glass wool, spray foam, and mineral wool – we’ll make sure the most appropriate one is used for your property.

Room-in-roof-insulation

Room-in-roof insulation is used in loft spaces that are converted into usable rooms. It improves your home’s energy efficiency by keeping your new space warm and also creating an extra barrier against heat loss from the rest of your house.

What are the benefits of new wall insulation?

There are many benefits that can make new wall insulation a perfect choice for your property:

Reduces heat loss

With 35% of a home’s heat potentially leaving through the walls, wall insulation creates a barrier to trap this warmth.

Better energy efficiency

Since less heat is escaping, your property can become more energy efficient, helping you save money on your monthly utility costs.

Lower carbon emissions

Wall insulation can also help reduce carbon emissions by reducing heat loss. This is because you use less energy to heat and cool your home.

Better property value

Looking to sell or rent your property? Wall insulation makes it more energy-efficient, potentially increasing its value and bringing you more money.

Better soundproofing

Wall insulation can help improve the soundproofing of your home, giving you a more peaceful place to enjoy your day-to-day life.

The two surveyor's who came out were very professional and personal, we had a laugh about one being a Wigan warriors fan and we're Rhinos fans lol. Then Rob who came out to fit the boiler again very professional and personal, very tidy workmanship. Can't thank your company enough, new boiler fitted in less than a week and easy to deal with.

Wall insulation FAQs

We’ve answered some of the most commonly asked questions about wall insulation here, but please speak to the team if you have any more questions.

Is it worth it to insulate cavity walls?

Absolutely. About a third of the heat can be lost in uninsulated homes through the walls. Properly insulated wall cavities keep you warm and save you money on your monthly utility bills.

What is the best way to insulate a cavity?

This will depend on several factors, such as your property’s size and age, location, and heating habits. We’ll conduct a thorough survey before doing any work to find the perfect solution for your property.

Can you put too much insulation in walls?

Yes, you can put too much insulation in walls. While it might seem that the more insulation you have, the warmer you will be, over-insulating can lead to bad ventilation, condensation and even mould problems.

Should I remove the old insulation before adding new?

In most cases, you don’t have to remove old insulation before adding new material. However, this does depend on factors like the age and condition of your existing insulation.
