J&J Insulation can provide open and/or closed-cell foam insulation for both commercial and residential properties. Each type of
foam spray insulation has specific benefits. Drawing on our extensive, specialist knowledge, we can work out which parts of your property will benefit most from open-cell spray, and which will be better suited to closed-cell foam. We can create customized solutions that are guaranteed to leave your property well-insulated against both thermal and acoustic transfer.
Closed cell foam, as the name suggests, consists of many individual cells, each of which is completely closed off from its neighbours. The result is rigid insulation that’s extremely strong.
Open-cell foam doesn’t have closed off cells; rather, the spray is designed so that the cells which are formed are open along one wall.
This gives flexible insulation that has a spongy texture. Both play a valuable role in an insulation project.
The R rate refers to the rate at which heat can be transferred through a solution: stronger insulators have a higher R-value, whilst those that let heat through more easily have a lower R-value. Generally, closed-cell insulation is a significantly better insulator, with an R-value of between 7 and 8. Open-cell insulation, in contrast, has an R-value that’s usually somewhere between 3 and 4, depending on the product that’s used.
Each product has its pros and cons. Closed-cell foam insulation has a significantly higher R rating, and its strength means it can help to support your property. That said, it’s significantly more expensive, and its lack of expansion means it’s not suitable for awkward spaces. Open-cell insulation is cheaper and expands far more than the closed cell option.
When our team assesses your property, we will recommend which parts of the property will benefit most from an open-cell spray, and which need a closed cell option. We frequently use both types of products in the course of a single job, varying the option that we use depending on the part of the building that we’re working on.
Good-quality insulation will significantly reduce the transfer of heat through the walls and roof of your property. This should mean that less energy is required to keep your home at an optimal temperature, so the A/C will be needed less in summer, and the heating will be needed less (or at a lower temperature) in winter.
