Speedway The open cell spray foam insulation contains a density of 0.5lb. per cubic foot. The greater the density of the foam the heavier, or stronger it will become. This particular type of polyurethane foam is referred to as “Open Cell” because of the nature of the chemical reaction during the installation process. When the polyurethane foam is being applied the tiny cells of the foam are broken causing air to fill the “open” space inside the material, resulting in a soft or spongy material. The open cell foam carries an R-Value of 5 to 5.5 per inch (R-Value is the measure of thermal resistance, which can be found by identifying the ratio of the temperature difference across a spray foam insulator and the heat flux). 0.5lb. foam products use significantly less material than 2lb. foam products do when completing the same sized job, making them attractive to an individual concerned with conserving the foam material. Due to the fact that open cell foam requires less material, the cost of the project is much cheaper than it would be if you were to apply closed cell foam.
How to Remove Foam Sealant From My FingersOne of the most important keys to reducing your heating and cooling costs is having your home well-insulated. So what is the best insulation for your home? Spray Foam Foam insulation has two forms: Open and closed cell. Both are made from a polyurethane material and have different propellant agents added. Some are made from biodegradable materials, such as soybeans, to make the off-gases friendlier to the environment. Foam is probably the best insulation for blocking air infiltration combined with high R-value. Installed by a professional, the price of spray foam varies depending on the thickness of the walls and type of foam. Spray foam insulation is probably the best overall insulation on the market if you can afford the cost. Foam insulation lowers your heating and your cooling loads when installed correctly. Additional benefits are elimination of air infiltration, keeps out dust, mold and allergens, and does not sag or deteriorate. Open cell foam is used more in residential applications. It is less expensive to install and is easier to work with after it's in place. Open cell allows water to penetrate, so it makes an excellent roof deck insulator. If water is allowed to penetrate, you can locate roof leaks before the decking deteriorates. Biggest benefit of open cell is heat transfer in sunny locations. It takes approximately 36 hours of sun to penetrate through 8 inches of foam. This is also true for walls. So when the home is cooled, it will stay cool. The warranty of the roof material is not voided with the installation of spray foam insulation. Closed cell foam has a much more structural component to it and can support some weight without compression. Closed cell does not allow water to penetrate and is an excellent insulator for basement and crawl walls where water could be a problem. Closed cell foam has a higher R-value per inch but is very ridged and tough to work with after installation. It is most often used in commercial applications. However, it has its useful applications in homes. Foam insulation keeps mold out of walls. Mold occurs in walls with batt insulation because of "thermal loop effect". This is where the heat penetrates the exterior wall, coming in contact with the cooler interior surface of the drywall, causing moisture to form. Moisture above 25% can provide an environment for mold to grow. Spray foam blocks this heat transfer and has no air gaps in which moisture can form. One way to combat the higher cost of spray foam is to combine a couple of inches of closed cell foam with fiberglass batt insulation installed over the foam, getting the exceptional air-blocking value of foam, with the high R-value and lower cost of fiberglass insulation. Spray foam insulation costs more than fiberglass batts, but it also has approximately twice the R-value of typical fiberglass batts insulation. By combining the two you will get the best of both. Foam insulation is also particularly good for remodeling projects when there is only easy access to the basement or crawl space and the attic. By blocking the air flow from the top (attic) and bottom (crawl or basement) you stop the draftiness that some older homes have, thus making the home more comfortable. A more comfortable home is what we all are looking to achieve. Spray foam can give you warmth in the winter and cooling in the summer when combined with the appropriate HVAC system. These systems can be smaller in size when your home is better insulated with less air infiltration.
Fireproof Insulation Materials (with Pictures)Thermal Spray Foam Insulation is used in buildings, and refers to the application of thermal insulated materials, which are applied using various spraying methods, into a roof space or wall cavity to prevent heat loss. The application of this process is normally completed within two days. Thermal spray foam insulation does not particularly address ventilation or sound proofing issues. It simply refers to the insulating materials being used to slow heat loss. The effectiveness of it is usually evaluated by its R-value, but this does not take into account construction or local environment factors. Thermal spray foam insulation is easy to apply. Foam insulation is sprayed onto or into the underside of the roof within the attic/loft space, and dries to a rigid foam. Thermal spray foam insulation is an important factor to achieving thermal comfort for the buildings occupants, and thermal spray foam insulation reduces unwanted heat loss, and reduces the energy requirements of cooling and heating systems. Thermal spray foam insulation simply refers to the insulating materials being used to slow heat loss. One of the most effective types of insulation spray is polyurethane foam, which has been specifically formulated for use within the insulation industry. This type of foam is a very cost effective insulation material, and works in two ways by keeping the desired space or area warm in winter and cool in the summer. It can also help with the problems that arise from condensation, and is an ideal solution for ambient and cold storage. Polyurethane foam is easy to apply, lightweight in structure and can cover large areas quickly and efficiently, making it a very cost effective solution for many commercial requirements. The application of foam spray uses a rigid polyurethane foam which sprays to a fine cellular structure with high compressive strength and good adhesion and insulating qualities. Many of these foam spraying techniques and materials do not contain or use any CFCs. Thermal spray foam insulation will adhere to most structures and other materials such as fibre, sheet metal, cement, asbestos sheeting, concrete and steel. When sprayed it can expand to over thirty times it thickness. It is lightweight in structure, weighing only three kilos per square metre at a depth of fifty millimetres. (approx) Insulating a building with this method will help to keep it warm in the summer and cool in the winter, reducing temperature control costs and providing a dry and comfortable environment for staff and workforce, and controlled storage for stock and materials.
How to Fix Holes in Tree TrunksNow contemplate the recreational elements of the home, such as pools, spas, boats, recreational vehicles and trailers. Reducing the costs of heating your pool water by up to half will be easy if the underlying cavity and sides are insulated with polyurethane foam. Campers and trailers are rarely insulated beyond a cursory overlay, resulting in diminished use during the spring and autumn months. Why not extend your annual use of recreational vehicles by adding a layer of spray foam insulation? Plus, don't forget the spray foam will also help deaden noise from the road. Pleasure boats, dinghies, even yachts can benefit from polyurethane foam. Aside from the insulating qualities, there is added buoyancy. For small vessels like row boats and the kid's summer dinghy, that could be a great added safety benefit. In new construction and large renovations there is often a need to fill voids for adding to the structural integrity, sealing up air pockets, smoothing out uneven cavities and insulating HVAC components. Polyurethane foam is the perfect solution for all those needs. It gets into those little spaces and expands until there is nowhere else to go. Even buildings formerly used for storage can be spray foam insulated and converted to residential use. Or how about converting an old van or bus into a recreational vehicle? Insulate it with spray foam and you have a quiet, warm place to sleep while on that summer road trip. We know one of the qualities of polyurethane foam is the ability to repel moisture, and in turn prevent mildew and mold. In the event of a water problem such as a residential flood or hurricane damage, spray foam will provide a temporary dyke while a more concrete solution can be arranged. Now let's take that ability to resist liquid one step further, to hazardous materials. Polyurethane foam also resists oil and petrochemicals, which mean it can be used as a temporary hazmat spill containment solution.
