Eco-Friendly Loft Insulation Materials We Offer

We all want to take steps to curb our energy wastage, whether it’s for our own financial benefit, the good of the environment, or both. Installing sustainable loft insulation can be a great approach to both – reducing your carbon footprint and, by extension, the amount of heat energy that escapes your home. Whether you are installing from scratch or replacing old insulation, we are here to help with whatever you need.

Once the loft 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 professionals are experienced in handling a number of loft insulation products, including Sheep Wool, SupaSoft recycled plastic, and SuperFOI, as well as any kind of fibreglass and mineral wool that may already be installed in your attic.

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

While it may seem futuristic, foil insulation is clean and simple to install.

Loft Insulation Overview

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 allowing some air to breathe out to regulate the temperature and prevent the food from overheating. Too much vapour escaping can create condensation, so it’s all about striking a good balance.

    Loft Insulation Installation FAQs

    While there are some individual factors to consider when recommending how much loft insulation to install, a general set of industry standards must be adhered to in most cases. The minimum amount of insulation required for a loft is 250mm. This applies to every type and combination of insulation materials.

    If you have insulation already installed that is below this regulation standard, but do not want to fully replace it, we have you covered – our installers can neatly fit an extra layer of sustainable insulation on top of the previous material, be it mineral wool, fibreglass or anything else currently installed.

    Different insulation materials may have different lifespans, but one thing is certain – sustainable alternative materials all last an extremely long time and, under normal circumstances, rarely need to be replaced during the course of a person’s lifetime. 

    60 years is the minimum lifespan of most of our insulation products, which may not be the sort of timeframe in which you can realistically plan inspections and replacement installations in advance, but it’s worth keeping in mind! If your insulation gets compromised by some unforeseeable household emergency, we can come to check and replace it immediately.

    Depending on the age of your property and a few other factors, we will recommend different materials for your loft insulation. For houses built before the roaring 1920s, Sheep Wool is the recommended material. Mid-aged properties built from near the beginning of the 1920s to the year 1965 will benefit most from SuperFOIL. Lastly, for owners of modern homes built post-1965, SupaSoft recycled plastic insulation is the safest option. 

    If you’re still unsure of which insulation material would best suit your home, or have a specific set of requirements that must be adhered to, feel free to liaise with our team of expert insulation installers. We’ll be happy to help discover the right package for you.

    Alas, there is no objective answer to this question, as each loft insulation package has its own set of advantages that make it suitable for different scenarios.

    • Foil is versatile, heat-resistant, and ideal for hotter climates. 
    • Sheep wool is long-lasting, vermin repellent, and totally organic.
    • Recycled plastic is highly productive for the environment. 

    Each of the above insulation types, whilst offering a defined set of benefits, is suited to homes and buildings constructed within specific eras. Sheep wool, for example, is the perfect natural solution for properties built pre-1920s – with its hygroscopic properties perfectly poised to fight troublesome damp spots in vulnerable timber trusses.

    Yes, it is definitely sensible to install loft insulation – particularly in today’s turbulent energy environment. It’s an extremely worthwhile investment in every sense; saving you money on your bills while also improving your overall quality of life. Better home comforts you will instantly notice include more consistent temperatures throughout the house, lower energy bills/lessened need for heating, and, if you have a loft storage conversion, safer maintenance for your belongings.
