How Does Internal Wall Insulation Work?

The goal of internal wall insulation is to improve a property’s overall energy efficiency and thermal performance. We use SuperFOIL insulation on the internal walls of properties built after 1920. Generally speaking, Sheep Wool will be used on properties built before 1920, though this will occur more rarely.

Thanks to its versatility, SuperFOIL can easily be applied to inside walls. Once installed, it acts as an effective radiant barrier able to redirect heat from all angles, keeping the interior of the home at a consistent temperature throughout all seasons. Sheep Wool protects older houses with untreated timbers by absorbing moisture that would cause condensation, all thanks to its hygroscopic qualities.

03

"Mr. RJ, Tear Down These Walls!"

Without any further ado, we’ll tear off any wallpaper or panelling on the targeted walls in order to make way for the new insulation structures. Rest assured that our installation team are extremely careful when dismantling your internal walls, always making sure not to damage the integrity of the overall structure or anything surrounding them.

04

Erecting Support Battens

Before laying down the insulation material, we will place supporting wooden battens to keep the insulation in place. On top of providing more stability, these battens can also improve the evenness of the walls they are applied to.

05

Placing Insulation Material

At last, we can begin fitting the SuperFOIL rolls between the internal wall and support battens. Acting as an effective, breathable radiant barrier to absorb and reflect heat back indoors, the multifoil sheets will spread across the whole wall, leaving no gaps exposed.

06

Fitting Plasterboards

Lastly, we cover up the bare insulation with solid plasterboard to create a seamless finish that blends in with the rest of the decor. With your new internal wall insulation installed, you can safely treat the new structure like any other wall in the house.

    FAQs

    Internal Wall Insulation Installation FAQs

    To get the ideal R-value – the measurement for the amount of heat diffused across a solid surface – it is recommended that insulation on the internal walls should have at least 60mm of thickness, though it can be boosted up to 100mm if necessary. SuperFOIL rolls are thin individually, meaning they can easily fit inside thin internal walls, but for thicker stone walls, they can be stacked up to form a solid yet breathable layer of insulation. 

    Unsure of how much insulation you’ll need? Don’t worry, our team can measure out your internal walls before beginning the installation.

    Some homes may already have internal wall insulation installed, either as part of the initial construction or fitted by previous occupants. If this is the case with your property, chances are it’s working well and you’re feeling the many benefits of it – life’s good. However, inadequately installed wall insulation can be problematic. If you aren’t happy with the quality of your current wall insulation, we can either perform a full clear-out and replace it from scratch, or we can top it up with additional material to boost it up to the recommended thickness.

    Yes, insulating internal walls can be a very worthwhile investment. For a start, the amount of money shaved off of heating bills thanks to reduced energy consumption is enough to convince anyone of the benefits. After installation, it won’t be long before the insulation will have effectively paid for itself. Since SuperFOIL wall insulation lasts for many decades, you will likely recuperate the initial cost of installation several times over by the time it eventually has to be replaced. When factored in with its other highlights, including minimised condensation and property protection, overall, multifoil wall insulation is great value for money!

    The vast majority of homes throughout the UK do not have insulated internal walls, as there is no rule stating that you have to get them insulated. However, there can be many visible benefits to investing in this form of insulation, including reduced energy bills, no more draughts, improved temperature regulation, and much more. In other words, while you don’t have to get your internal walls insulated, it can massively improve your quality of life, and will most often pay for itself in the mid-term.

    Most internal wall insulation should last the lifespan of your house, so it will not need routine replacements. As such, we offer a 60+ year guarantee for our eco-friendly insulation. In the event of lambswool being used for internal wall insulation in a pre-1920 property, rest assured that it also has amazingly high longevity. This is part of the reason why internal wall insulation can be such a worthwhile investment, as a single installation can effectively last a lifetime and the money saved on energy bills will eventually dwarf the amount paid for the initial installation.
