A high level of insulation(R) is used in residential buildings to achieve net-zero energy and safe carbon emission goals. People use cooling and heating devices to be relaxed and comfortable while being in their own space, adversely affecting the environment. Not only the air conditioning devices but the fridges also release harmful gas into the atmosphere.
Spray foam, both open cell and closed cell, insulates and seals your home. Sound dampening properties, mold prevention, and reduced airflow while preventing draughts and cold flooring are just a few insulation advantages. It can also help you save money on your monthly energy expenses. Spray foam insulation impacts conduction (heat transmission) and convection (airflow), affecting your home’s comfort and energy efficiency. Insulation’s primary purpose is to prevent heat from escaping or entering a place. In the winter, it keeps your home warm, and in the summer, it keeps it cool.
Consider the difference between a wool sweater and a windbreaker when comparing traditional insulation – fiberglass and cellulose. On a chilly fall day, a wool sweater is both warm and welcome. If the wind blows and runs directly through your wool sweater, it won’t keep you warm. A windbreaker, similar to spray foam, will be far more effective in keeping you warm.
Many homes have air leakage, which leads to energy loss and the inconveniences of draughts, hard flooring, and ice dams. Imagine the impact on heating and cooling expenditures if certain homes leak enough air each day to fill two blimps. Some open-cell spray foam insulation expands up to 100 times its original size, filling the hole and preventing air leakage. Traditional insulation, such as fiberglass and cellulose, might leak air if crevices and gaps aren’t covered.
Spray foam can help you achieve a draft-free, energy-efficient house. Spray foam insulation can be either open-cell or closed-cell. While both materials create an air seal, some differences between them can make a difference for your project. Let’s take a look.
Open Cell Spray Foam Insulation
Open Cell Spray Foam Insulation is spray-applied to open cavities in any structure.
In an existing home, a new residence, or a pole barn, open-cell insulation creates an air seal and continuous insulation. Spray foam insulation is light, malleable, and may expand up to 100 times to fill every nook and crevice.
Here are just a handful of the benefits of open-cell spray foam.
Open-cell tends to be cheaper than closed-cell but still provides the same air seal you’re looking for. As your home shifts and settles, open-cell will move with the structure without cracking or pulling away from the studs. Water can pass through the open cell, but it does not soak it up and hold it like a sponge. When it gets wet, it will dry quickly without increasing mold and mildew growth. Open-cell spray foam can help with sound dampening if you want to reduce noise in your home. It won’t be utterly soundproof in your home, but it can help reduce the sound that comes in. Water is the blowing agent for open-cell spray foam.
Closed Cell Spray Foam Insulation
Closed-cell spray foam insulation is a spray-applied plastic that creates an air seal and continuous insulation. Closed-cell spray foam is applied to the open cavities of existing homes, new homes, pole barns, and commercial buildings. While we don’t usually recommend closed cells for homes, there are instances where it is the better fit over open cells, mainly if the structure has limited space. Closed-cell is more commonly used in pole barns, commercial establishments, and vans.
Here are the benefits of closed-cell spray foam.
Closed-cell spray foam is durable, so it can be left exposed without worrying about damaging the foam.
Closed-cell spray foam is impervious to water, but that doesn’t mean it shouldn’t be used to plug any leaks. It, like an open cell, reduces air leakage in the area where it is put. Closed-cell spray foam is ideal for smaller applications like cargo vans and tiny houses since it has a low expansion rate.
