Welcome to this informational guide, in which we discuss how to prevent cold bridging in your property’s insulation.
For those who have tried to prevent cold bridging in the past and not managed it, we explain the best ways to avoid it so you don’t have any issues in future.
What is cold bridging?
To simplify, cold bridging (often referred to as thermal bridging) is a vulnerable spot in the insulation surrounding a property, and it appears when there is a gap in the continuity of insulation. Where there is no air tightness you are most likely to find examples of cold bridging, like in lofts, walls, windows, ceilings, roofs, doors, holes for pipes and in the floor.
Why is it important to prevent?
The benefits of preventing cold bridging are numerous, and as such, new building regulations have placed a greater emphasis on designing buildings that do not allow for it.
- Warm air escaping means wasted energy and costs to the homeowner
- Cold air entering reduces the temperature of the home or property and creates a higher demand for energy
- Up to 15% of wasted energy in the home is due to cold bridging
Is cold bridging really a big deal?
Absolutely! If you care about your money, your home and energy conservation, it’s important to pay notice to the amount of warm air escaping. You wouldn’t have the heating on and sit with the window open, would you? All of the cold bridging sites in your home combined could equate to an open window, or worse, so it’s worth doing what you can to prevent it.
If you’re going to pay for insulation, it’s worth doing it properly and reducing the chances of cold bridging. It’s a common misconception that cold bridging is not 100% curable, due to the design of homes, but it can actually be tackled properly.

What do we recommend as the best solution?
Our number one recommendation is, and has always been, Spray Foam Insulation Systems by Home Logic. Most insulation types deliver some conductivity performance, but they don’t always offer the best energy performance, and are not as environmentally friendly as . is the best way to prevent cold bridging (other than through building design, but it’s usually too late to change that) and is the most efficient option against air leakage. 50% energy savings and reduced carbon dioxide emissions (thousands of tonnes per year) mean that you can earn back your insulation investment in just 3-4 years. Airborne pollutants, noise, allergens and moisture are all tackled with the air seal, meaning the air is cleaner; this prevents mould and condensation.
Reduced carbon footprint?
Compared against other conventional insulation methods, hygienic and odourless spray foam can boast the lowest carbon footprint in the world for transport due to its incredible lightness and compact nature. To complement this, it’s superior performance as an insulator means that you will prevent wasting energy from your home, and we are talking about thousands of tonnes of CO2 per year. The spray comes in liquid form, and once applied, expands to around 100 times its original volume, filling up all the cavities, giving an answer to our question: ‘how to prevent cold bridging’. It also remains secure, light and follows the building structure without cracking over time.
If you are looking to improve the heat retaining performance of an existing building, a professional will be able to find the cold bridges, drill holes and apply the spray foam without having to remove sections of the wall.
How to prevent cold bridging in business properties?
The design of homes and business premises are usually quite different, but maintain many of the same attributes. The focus on insulation in business environments is often not as important as the structural security, but can reveal itself to be more vital over time – especially if staff complain about the cold, and management about the energy bills! Closed cell foam spray is the best option in this case.
