How To Insulate A Roof Void With Spray FoamBy admin
Thursday, 19 September 2019
As of 2013, 23.7 million of the 27.1 million homes in the UK have loft spaces, but many of them remain uninsulated.
The roof of a property is responsible for around 25% of the overall heat loss, which means that a quarter of the heat that you’re paying for is escaping through the roof. Slowing down the loss of heat translates to large savings on energy bills and creates a home that stays warmer for longer.
One of the most popular choices of insulation material for roof voids is spray foam insulation – a product that is perfectly designed to prevent heat loss and seal the roof of a property against many common causes of damage.
If you’ve never encountered spray foam before or you’re considering insulating your roof for the first time, then you may be wondering how to insulate a roof void with spray foam insulation. Well, wonder no longer!
Read on to discover everything that you need to know about spray foam insulation for loft voids!
With spray foam insulation, the product is naturally able to combat many of the problems, like moisture control and mould resistance. The versatility of spray foam also means that you can easily choose between a cold roof and a hot roof
Key Considerations When Insulating a Roof Void
Insulating a loft completely changes the environment inside of a property. The property will be warmer inside during the coldest months of the year and cooler during the warmest months of the year.
Despite the great benefits of spray foam insulation, a key part of insulating a loft is understanding what you need to look out for. Here are some of the main considerations when trying to insulate a roof void effectively:
- How well the roof void is protected against possible moisture problems, like condensation and leaks.
- Whether the environmental conditions in the roof void mean that the roof is prone to mould problems.
- If there are pests in the roof void and how easily pests are able to enter the roof.
- Whether the roof void is properly ventilated to stop problems with condensation.
- The condition of the roof and whether it’s strong enough to support the application of insulation materials.
- To what extend the roof void is going to be used, such as for a loft conversion or storage.
To make sure that a roof void is properly ventilated and that all the other key considerations are addressed before the insulation is installed, it’s vital that you seek the advice and expertise of experienced installers.
Whether you want a hot roof or cold roof, or have an inaccessible loft, at Home Logic, we can take care of your spray foam roof insulation for you
Deciding Which Type of Roof You Want: Cold Roof vs Hot Roof
An important part of how to insulate a roof void is deciding whether you want a cold roof or a hot roof. Spray foam is an excellent choice for either roof type, but which one is best for your home will largely depend on how you want to use your roof:
This is where the insulation is installed between the joists on the floor of the roof void. With a cold roof the building envelope ends at the floor of the roof, so the roof void will remain cold in the winter and hot in the summer.
This is where the insulation is installed on the underside of the roof rafters. With a hot roof the building envelope extends to the roofing materials and the insulation will help to keep the roof area warm.

Installing Spray Foam Insulation: Accessible Roof Void vs Inaccessible Roof Void
The method for insulating a roof void with spray foam can change depending on the type of roof that your have. If you have an accessible roof then it’s very easy to choose between a hot roof and a cold roof, while an inaccessible roof can greatly limit your options.
Accessible Roof Void Insulation:
For an accessible roof void, spray foam insulation will often be applied via a spray. The material is blown onto the surface to create an even layer that helps to eliminate cold and hot spots.
Inaccessible Roof Void Insulation:
For inaccessible roof voids, spray foam insulation will normally need to be injected into the space. Small holes may need to be made for completely inaccessible lofts, where the insulation will be injected into the void to create a consistent insulation barrier.
This method is often used to install spray foam in any inaccessible space in a home, like crawlspaces and cavity walls.
