Your Building Insulation Needs An Upgrade. Here’s Why.

Building insulation. Hardly the most exciting purchase you can make, is it? But in actual fact, the right building insulation can make significant improvements to your office, warehouse or commercial property – some saving you money. Now, that’s more exciting, right?

So let’s talk building insulation and why upgrading yours could be the best thing you do all year…

What Is Building Insulation?

In case you’re not savvy with all things property related, we’ll cover what building insulation is before we get to why you might need an upgrade on it.

Insulating a building means including a thermal layer to minimise the transfer of heat from inside the property to the outside. Insulation has been used since the 1930s and as you can imagine, has improved over the decades. 

Nowadays, building insulation comes in a variety of materials, each offering differing benefits. They include; 

Spray foam insulation

Spray foam insulation is probably the most versatile building insulation on the market. It starts as a liquid which is sprayed onto the area that needs insulating, where it expands and hardens. Its rigid form makes it more consistent than other forms of insulation, and it can even repel water.


Insulation board

Insulation boards are the most common type of building insulation used. They are solid blocks of either Polyisocyanurate (PIR) or Polyurethane (PUR), and they provide excellent thermal efficiency.



Blanket insulation, also known as roll or batt, is just as common as insulation board. Rather than having a rigid form, batt and roll is soft and flexible (it’s like a blanket, hence the name). Made from fibreglass, mineral wool and even sheep’s wool, it’s the cheapest insulation solution available and is favoured among loft insulation DIY-ers.


Multifoil has a clue in the name – this type of insulation uses layers of foil to trap and reflect heat back into a space. Some types of multifoil also have a fibre core or bubble structure to maximise their capabilities. Multifoil is the thinnest insulation solution on the market, making is ideal for places where space is tight.


Now, not all insulation is for keeping warmth in – some is designed to reduce sound travel. Acoustic insulation is a dense material made from fibreglass and mineral wool which absorbs soundwaves, helping to soundproof a room. Some thermal insulation materials, like sheep’s wool, are also good at soundproofing too.

Common Building Insulation Problems

So, what are the common problems we see with building insulation? 


Insulation will degrade over the years, so if your building’s insulation was installed over 10 years ago, it might be starting to fail. It won’t be as effective as maintaining the heat so you’ll be paying more in energy bills.


Roof leaks, pipe leaks, and condensation caused by air gaps – these are just some of the reasons why your insulation might be wet. Needless to say, soggy insulation isn’t going to be much good at keeping your building warm, and worse still, it could cause mould growth. If left, mould can be harmful to your building’s occupants.


Pests like rats and mice love to make a home in your warm, soft insulation. If, following an inspection, you spot droppings or patchy insulation in some areas, you’re going to need to replace it all.

Hazardous Materials

If your building is really old and hasn’t had an insulation upgrade, you might still have asbestos insulation. Asbestos was the golden child of the construction industry for decades, with the 60s and 70s seeing over 170,000 tonnes imported to the UK. It was used as insulation for walls, lofts and pipes, as well as in roofing sheets and floor tiles. And then, it was discovered that it was the reason for the huge occurrence of cancer among those who used the material regularly. Asbestos was banned in 1999, but it is still present in thousands of buildings throughout the country.

The Benefits Of Upgrading Your Building Insulation

The key benefit to upgrading your building insulation is much improved thermal efficiency. New insulation can reduce your energy costs by up to 25%, so it can pay for itself in a short time.

But it’s not all about keeping warm – the soundproofing qualities are also highly useful. Whether you want to reduce infiltrating noise from outside or you want to prevent your disruptive work from annoying your neighbouring buildings, building insulation offers a brilliant solution.

Let’s not forget the safety aspect. If you own one of those buildings with asbestos insulation, it could be causing serious long-term harm. Anyone removing asbestos must be licensed to do so, so make sure you do your homework when collecting quotes.

And that’s still not all – cutting your heating use down reduces your carbon footprint.

How Long Does Upgrading Your Building Insulation Take?

Closing your business or building while your insulation is replaced might be one of the reasons you put it off – after all, it’s costing enough to have it upgraded, you really can’t afford to shut down too.
