Interior Walls Spray Foam Insulation

Looking to insulate the interior walls of your house? The most energy-efficient insulating material on the market is spray foam insulation. It not only protects your home from dust and rain, but it also protects it from toxic moulds and degradation, and decreases energy costs and pollution.

Fitting your home properly with spray foam insulation can regulate thermal energy, reducing the loss of it by as much as 50% through walls, windows, and doorways.

At Ifspray, we install spray foam insulation that is both thermally insulating and breathable, whether it is a new build or an existing house. Because of the open-cell nature of the foam, it enables buildings to breathe naturally and offers a vapour-open interior wall insulation solution that can be added straight to the masonry walls and protects the walls with an internal board finish attached to stud work.

We cover England, Northern Ireland, Scotland, and Wales. Contact us today to have your home properly insulated by spray foam insulation specialists.

What are the Advantages of Insulating Interior Walls with Spray Foam ?

Prevents Heat “Theft”

Insulation of your interior walls with spray foam is a must when party walls are present. These are walls that divide individual living spaces. You most probably will want to cut back on sound and thermal transfer between apartments as a matter of priority. Imagine if no one lived in the apartment that your party walls link you to? Because this apartment does not get heating, it will "steal" heat from your flat. Besides, even if someone does live there, you still do not want to lose the hard-earned heat of your apartment to your neighbours, nor will you want to have to be subjected to their noise (or have them subjected to yours!).

Reduces Heat Transfer

If you've got empty space, you need insulation. Simply closing vacant rooms won’t be of much help in an environment where there are significant temperature fluctuations. Internal spray foam insulation can reduce the heat transfer that happens due to empty space.

Dampens Sound

Interior spray foam insulation provides the advantage of sound dampening. The application of spray foam insulation will reduce the transfer of vibration and sound from one room to another.

Saves Energy

Spray foam insulation in the interior walls also provides significant energy savings. It will save a lot on utility bills if you have rooms that are not in use all year round. Rooms suitable for interior wall spray insulation include storage rooms and guest rooms that are not used.

It’s simply not true that insulating the roofline with spray foam insulation can create moisture problems with the roof sheathing. In an unvented attic situation, a continuous air barrier is needed to prevent air exposure, as well as any possible condensation at the roofline.

Spray foam insulation is a great product. Homes insulated with it are among the most energy-efficient and comfortable homes. When spray foam is properly installed, it outperforms 99% of fibreglass-insulated homes.

According to EPA, when air leaks are sealed and efficient insulation such as spray foam is installed, the monthly energy bills can be cut by up to 20%. The initial cost of spray foam insulation is well worth the expense after factoring in the long-term net benefits that will follow.

Yes, you can. Insulating internal walls with spray foam lowers energy bills, reduces noise, and discourages pests.

Spray foam is a great insulator, but it is made of chemicals and needs to be treated with caution. Although kits are sold in hardware stores encouraging homeowners to install it on their own, it’s better to hire specialists to do the job. As experts are familiar with R-values and how to provide the necessary thermal protection, a specialist will help you choose the best spray foam insulation product for your property.
