Three questions to ask when insulating your home with the Green Homes Grant scheme

By Knauf Insulation UK & Ireland on October 07, 2020

You’ve seen the headlines, and you’re thinking of using a Green Homes Grant to improve the energy efficiency of your home.

If you’re here, that means you’re thinking about insulation. Well done – that’s the right place to start, because improving the insulation is one of the best ways to turn a draughty house into a cosy home. Even if your home already has insulation, the chances are it could be improved.

But there are many different types of insulation, and they all perform slightly differently.

That matters because insulation isn’t just about keeping your home warmer in winter and cooler in summer. Choosing the right insulation can make it safer, quieter and healthier too.

Your accredited Green Homes Grant contractor will be able to advise on the right solution, but here are three simple questions you can ask them to ensure you’re getting the best loft, cavity wall or floor insulation for your home.

Do I want the insulation to be non-combustible?

Any work on your home will need to comply with the latest Building Regulations (your contractor will manage this). This is important because some insulation products are combustible and could contribute to the spread and development of a fire.

For peace of mind, you can ask your contractor to use non-combustible insulation. The easiest way to be sure a product is non-combustible is to look for its Euroclass Reaction to Fire Classification rating, which runs from A1 through to F. If a product has a rating of A1, it will not contribute to the spread or development of a fire if one occurs. Every Knauf Insulation Mineral Wool product for your home is A1 rated.

Do I want the insulation to block unwanted noise?

Lockdown saw millions of us working from home. So, you probably know just how disruptive unwanted noise can be – whether from busy roads, noisy neighbours, household appliances or even just your children playing in the next room.

But did you know that unwanted noise isn’t just a nuisance – it’s bad for your health too? People living in noisy homes suffer more from headaches through to heart attacks.

Adding insulation is one of the easiest ways to block unwanted noise. Not all insulation types are good at absorbing sound e.g. rigid foam boards, which allow it to pass through. Choose mineral wool insulation if you want a quieter home because it absorbs sound instead.

How will the insulation affect indoor air quality?

If you’ve ever bought paint, you may have heard of Volatile Organic Compounds – or VOCs – before. VOCs are chemicals – like formaldehyde – that can affect the air quality in your home. Long-term exposure to high levels of VOCs can cause skin and eye irritation, nausea, headaches and asthma.

When choosing insulation for your home, it’s best to look for low VOC products. Again, there’s a simple classification system you can use – look for a Eurofins Indoor Air Comfort (Gold) certificate. This gives you the best assurance that the insulation meets low product emissions requirements.

The Knauf Insulation products most commonly used in your home – like our Earthwool® range – have all been awarded Eurofins ‘Indoor Air Comfort GOLD’ certification. They are manufactured with ECOSE® Technology, our unique bio-based binder, which contains no formaldehyde or added phenols. This means they are better for your home, more pleasant for your builder and kinder to the environment.

Talking of which, our insulation is also made from up to 80% recycled content. Used glass bottles and jars are processed at a site just across the road from our Merseyside plant, so you can be confident your insulation choice is the right one for our planet.
