Insulation is a necessity for surviving the chilly weather in the UK. Whether it is a domestic property or a commercial one, perfect insulation helps in making the space comfortable. Additionally, effective insulation can significantly reduce electricity bills.
If you are planning and searching for an effective way of insulation, consider spray foam insulation in Hampshire. Its perfect barrier helps in preventing heat loss and contributes to maintaining a comfortable temperature. However, before that, choosing between open-cell and closed-cell insulation is a mandatory step.
What is Open Cell Spray Foam Insulation?
Open-cell spray foam insulation is one of the most popular types of spray foam insulation in Southampton. In this process, the expert uses a spray that isn’t totally encapsulated. This makes them lighter and lower-density. Due to the structure, they can expand effortlessly to fill the gaps. It is a better choice for installation on complex roofs or where access is restricted.
The open-cell spray foam adheres strongly to the roof structure. The chemical structure allows it to be trimmed back and lined with plasterboard and vapour control layers in loft extensions. Some products are vapour-permeable. This allows moisture to pass through them. However, in this case, you need to plan a strategy to handle the condensation accurately.
What is Closed Cell Spray Foam Insulation?
Closed-cell spray foam insulation is used in older structures, as it is a denser product with a closed cellular structure. The special structure of the product prevents it from expanding, and it becomes rigid once it dries. Like an adhesive, it adheres to the roof structure and remains in place.
This rigidity contributes to better insulation, enabling it to withstand various weather conditions. Moreover, the lower vapour permeability makes the product compact and perfect for the smaller spaces. However, due to strict adhesion, it causes a degeneration of the roof and tiles.
Difference Between the Open and Closed Cell Spray Foam Insulation
Structure
Open-cell foam insulation has a lighter and more porous structure. On the other hand, the closed-cell spray foam insulation in Portsmouth has a more rigid format. The cells of this spray foam are entirely closed. This closed design offers rigid properties and prevents moisture from entering.
Expansion Capacity
Open cell insulation is designed to expand. With a one-layer application, the product can expand, averaging 100 times its liquid state and reaching a thickness of 100mm. On the other hand, the closed spray foam insulation in Hampshire is aimed to stick to one place and become rigid. They only expand 50mm with one application, which is approximately 40 times their liquid state.
Density
Open-cell spray foam insulation is known for its expansion capacity. Then it has a lower density. Typically, open-cell foam insulation has a density of around 0.5 pounds per cubic foot. While closed-cell spray foam is made to adhere to an object, it naturally has a higher density. Typically, it has a density of 1.75 pounds per cubic foot or more.
Open Cell and Closed Cell Spray Foam Insulation: Which One To Choose?
If you are looking for spray foam insulation in Southampton for a smaller domestic property, a closed-cell spray foam is the best option. It can handle smaller spaces effectively, offers the best insulation and prevents moisture. However, it can damage property. Therefore, it is crucial to connect with professionals for regular inspections.
