RJ Insulation Installation Services

Insulation is the process of retaining heat within an enclosed space. Think of your house as a cooking pot. Keeping a ventilated lid on will keep all the flavour inside, while also allowing some air to breathe out to regulate the temperature and prevent overheating the food. Too much vapour escaping can create condensation, so it’s all about striking a good balance.

Loft Insulation Installation

The loft is one of the most important areas of the house to keep well-insulated for all seasons. At RJ Insulation, we take pride in our commitment to providing sustainable loft insulation – installing it with great care, precision, and to the exact standard specified by PAS2030:2019.

Eco-Friendly Insulation Materials

In today’s climate, we are all more conscious than ever about the impact we are having on the environment and how we can reduce our carbon footprint.

Curbing your energy consumption is one of the best initial improvements to make, though you do not need to radically change your lifestyle – something as simple as fitting new, eco-friendly insulation can help a great deal.

Installing effective insulation can be a great way to regulate your home’s temperature, save you money on your energy bills, and help the planet by reducing carbon emissions. Once the insulation pads are laid down by a professional installer, they will keep your house warm in the winter and purify the air flow in summer. RJ Insulation’s installers are experienced in handling a number of insulation products, each specialised for different purposes. We take special pride in our commitment to supplying high-quality, eco-friendly materials to our customers.

Sheep Wool

Real, organic sheep wool is one of the most effective natural insulating materials. Sheep wool is hygroscopic, meaning it can reduce humidity levels throughout a household by easily absorbing large amounts of excess moisture and water vapour. If you have an older house with untreated timber frames, this trait can also reduce the risk of mould growth on wet wood.

  • Hygroscopic (moisture absorbent)
  • 100% organic
  • Lasts a lifetime
  • Safe to handle
  • Ideal for older properties
  • Locally sourced from British sheep
  • Non-flammable
  • Treated against attacks by clothes moths
  • Suitable for: Lofts

SupaSoft Recycled Plastic

Researching ways to reuse plastic waste has been a top priority of scientists for many years. Fortunately, among many other applications, recycled plastic makes for excellent insulation material. You will feel secure in the knowledge that you will not have to regularly replace our plastic insulation, which is remarkably fluffy, flexible and long-lasting. As a final bonus, our plastic insulation can, itself, be recycled!

  • Soft and safe to touch
  • No respiratory risks
  • Made of non-degradable recycled plastic
  • Clean and simple to install
  • Lasts a lifetime
  • Vermin repellent
  • Melts rather than burns on contact with open flames
  • Suitable for: Lofts

Foil is rapidly becoming the material of choice for insulating homes across the world. First seeing use aboard NASA spacecraft, affordable foil insulation is now endorsed by many countries as an essential installation for newer homes. While it may seem futuristic, foil insulation is clean and simple to install.

What Are the Telltale Signs of Poor Home Insulation?


Condensation Build-Up

With nowhere else for water vapour to escape to, you’ll find condensation regularly gathering on windows, sinks and walls. Our eco-friendly insulation materials can redirect and, in some cases, absorb excess moisture rising up through your home.


Chilly Draughts

Is a cold breeze constantly passing through your home, even during warmer weather? This may be caused by poor air circulation throughout your home and can be remedied by improving your loft insulation.


Pests Appearing

Poor insulation has a tendency to attract vermin, including moths, rodents, insects, and other parasites. They enjoy warm spaces and usually build nests in any gaps they find. Our sustainable insulation products do not attract pests and are durable enough to withstand their attempts to burrow through.


High Energy Bills

If you’re concerned about how much energy you are using while your bills keep rising higher, consider the amount of heat that is being lost to the outside world due to inadequate insulation. By retaining warmth inside your home, you will rely less on your heating systems, and your energy bills will subsequently decrease.


Different Temperatures Between Rooms

Always finding yourself stuck in a Christmas jumper in the kitchen, then switching to summer shorts when you move to the lounge? Noticeable temperature changes between different rooms or between upstairs and downstairs areas can be easily fixed with proper insulation!

Certified Insulation Installers

You may be wondering if our service is truly trustworthy. To assuage any concerns, several organisations have glowingly approved our service. RJ Insulation is a Which? Trusted Trader and Trading Standards Approved.

We were awarded a coveted PAS 2030:2019 accreditation for the installation of insulation, which also covers cross flow ventilation. Our installation team can also conform to PAS 2035:2019 regulations when we are required to do so.

    Frequently Asked Questions

    Upon your initial consultation with us, our team will arrange an ideal timeframe to come over to your property and begin the installation work. Depending on the scale of the project in question, insulation installation can take varying amounts of time, but we generally aim to complete most tasks within the realm of one to two days, though the vast majority will be completed within only one working day.

    True to our claims of nationwide coverage, our installation teams can travel vast distances to reach many locations across the UK. For practicality, we do try to stay within reasonable driving distance from Suffolk – as such, our only real limits for travel are the far western counties and islands disconnected from the mainland (i.e. Ireland, the Isle of Man, the Isle of Wight, etc.), but we can possibly make exceptions if you discuss this with us during our initial consultation.

    At RJ Insulation, we make sure to use the longest-lasting insulation materials on the market. Our three main materials of choice – SupaSoft recycled plastic, SuperFOIL and Sheep Wool – all have extremely high longevity. SupaSoft, SuperFOIL and Sheep Wool are able to last a lifetime – not just yours, but your home’s as well.

    Loft insulation is generally considered to be the most effective way to lock in heat, save money on energy bills, improve home comfort, and reduce condensation – all of the most meaningful advantages of home insulation. Eco-friendly loft insulation materials are especially desirable for their sustainability and great performance.

    Yes, we have recently expanded our range of services to include the installation of internal wall insulation. Our team can fit insulated boarding onto your walls in whichever room you deem to need it most.
