Internal Wall Insulation

Nationwide Internal Wall Insulation Installers

At RJ Insulation, we perform internal wall insulation installations with great efficiency. If your home has noticeably uneven temperatures or struggles to retain heat, you can have us inspect the thickness and stability of your internal walls; they may need some added insulation.

We are committed to providing efficient, environmentally-friendly solutions to our customers’ home insulation problems – improving their overall quality of life in the process.

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.

Why Get Your Internal Walls Insulated?

Installing internal wall insulation can be a great investment. From reduced drafts to capped energy bills, we’ve compiled a thorough list of the material and financial benefits internal wall insulation can bring!

Reduce Condensation

Improved insulation keeps most of the surfaces in your home at a consistent temperature, so the chances of warm vapour coming into contact with cold internal walls (or vice versa) to produce condensation are absolutely minimised. No condensation on the walls means no mould growth and a much healthier environment for you and the family, as well as reduced colds, coughs and respiratory complaints such as asthma.

Easily Installed

Some internal wall insulation jobs are as simple as grafting the material directly to the walls, with battens and boarding added for support. If you’re already planning to redecorate your home, internal wall insulation can be fitted seamlessly alongside whatever other decorative work you’re having done. The process is fast and free of mess-mongering.

Improve Temperature Regulation

The UK has been regularly bombarded with one-two combos of brutally hot summers and frigidly cold winters in recent years. Insulating your external walls with SuperFOIL or Sheeps Wool ensures your home is lovely and cool in the summer, while also keeping the family cosy all winter long.

Reduce Noise Pollution

Nobody likes noisy, inconsiderate neighbours, and no one wants to be one. Whether you want to keep harsh sounds inside or out, boarding up your walls with SuperFOIL insulation can dramatically reduce the effects of noise pollution. For soundproof internal wall insulation, call us today!

Cap Your Energy Bills

As with our other insulation packages, internal wall boarding will lower overall expenditure on energy for heating and cooling your property. With less energy wasted on the same job, you can save hundreds of pounds on your energy bills, too!

Reduce Draughts

By covering up small cracks that may be in your walls, you can prevent the circulation of chilly draughts throughout your home. Water vapour carried in these draughts can form condensation in a less insulated home – yours won’t be one of them when we’re finished with it!

Increase the Value to Your Home on Resale

Both agents and buyers can show favour for property listings with adequate insulation in place, including in the walls. A simple boarding installation can dramatically boost the value of any home that’s going up for sale, even if it’s done years beforehand.

The Internal Wall Insulation Process Made Simple

01

Initial Inquiry

However you decide to contact us – be it through our fillable contact form, our email address, or simply calling us directly – you will be put through to the lovely RJ Insulation team. You can discuss important matters like the age and state of your property, which walls you want to have insulated, and anything else of relevance.

02

Arriving on Time

We are committed to arriving at your home at the agreed-upon time. Previous customers have been pleasantly surprised by our professional dedication to timeliness and ability to travel cross-country in all weather conditions.

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.

From the initial call to the completion of the job, it’s been a pleasure to deal with RJ Insulation. After the survey, we were given a quote almost straight away but no hard sell or pressure attached to it. The date for installation was agreed. Two lovely guys turned up to fit the foil in the loft, both were very polite and courteous at all times. Dust sheets were put down and they hoovered up at the end of the job both days. I would recommend this company to anyone who’s thinking of having new loft insulation put in. You won’t get better than this, genuine people that take pride in what they do, a rare commodity these days.

R&J completed a loft conversion project for me in September 2021. From pre-sale to implementation, the experience of doing business with them was exemplary. Ron led us through a thorough, inclusive design process, where he and Max offered polite suggestions based on their experience, but always ensured we were getting exactly what we wanted. The statement of work and price breakdown were crystal clear, and they stayed in constant communication until the job was complete. Max and the rest of the install team carried out extremely high quality work, with great care and consideration, and the end result was absolutely perfect. It is clear that the whole team takes pride in the quality of the outcome they deliver, and it was an absolute pleasure to use their service. I would highly recommend R&J to anyone considering any kind of loft conversion work, they will not let you down.

Cannot fault the team at all. From start to end, nothing but amazing service. From quotation to updates on installation from Ron and Ross. To Max and his team turning up to carrying out the work. Treated our home like theirs. Friendly, polite and great workmanship all the way. We are so pleased with the results. Highly recommended the team.

We recently moved to a new property with a walk in loft plus a shallow loft at the apex of the house. The walk in loft was very draughty especially in windy weather. We could also hear every word spoken in the loft clearly in the kitchen/rooms below. We thought the SuperFOIL product would be perfect, as we’d read that many mortgage companies will not give a mortgage on foam products fitted between the joists making the property hard to sell. We contacted R J Insulations and were impressed with their Surveyors (initial quote and follow up prior to installation) and with the communication from the sales office. The installation team (3 guys) were brilliant. So organised. They prepared our house with sheeting to cover walkways, were informative about every stage of the installation and were so polite. The installation took 2 days. We had SuperFOIL on the joists in the walk in loft and SupaSoft between the rafters and also SupaSoft between the rafters in the apex loft space. The first thing we noticed was the reduction in noise – the SupaSoft

    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.
