IWI - Internal Wall Insulation Solutions


Insulating the internal side of a masonry wall is a very common method of insulation, particularly for retrofit, refurbishment or conversion projects, but can also be used on extensions or new builds.

This method of insulating your walls on the inside of your property can be an excellent way of combatting heat loss particularly for retrofit, refurbishment or conversion projects, due to the thin profile of our reflective insulation, which is why at YBS Insulation we have specially manufactured products for dry lining.

Dry lining involves installing insulation between timber battens on the internal side of your wall. Whether it’s for a new build or a refurbishment project. Dry lining insulation makes your home more energy efficient and is quick and easy to install, whilst achieving U-Values which will ensure you comply with Building Regulations and have a room which is comfortable for its occupants.

The recommended insulation for this method of construction is shown below.

SuperQuilt Internal Side Of Solid Wall

Our internal wall insulation solution is great for projects where there is an existing masonry wall or a new wall has just been built.

Installing a single layer of SuperQuilt between timber battens is quick and easy, due to its ultra-thin profile. Increasing the depth of the battens from 25mm to 38mm gives a higher thermal performance.

Need to meet a lower U-Value than building regulations?

Add insulated plasterboard to the internal finish or use multiple layers of SuperQuilt to your desired U-Value, for more information speak to our technical support team on 01909 726 025.

Once SuperQuilt has been taped and sealed on all overlaps and perimeter, it also works as a high performing VCL (vapour control layer).
