Spray foam comes in two flavors, open cell and closed cell, and provides both parts of the building envelope - the insulation and the air barrier. The building envelope should completely surround the conditioned space, and the insulation needs to be in contact with the air barrier. Since spray foam is both insulation and air barrier, proper alignment of insulation and air barrier is guaranteed. http://m.youtube.com/e/ggLAUsiuI_o
Spray foam is a fully adhered insulation that is spray applied into wall cavities, providing a continuous air and moisture barrier. Spray foam allows efficient use of your HVAC system and helps regulate the temperature fluctuations and humidity in your home. Spray foam effectively seals the building envelope, filling in any cracks and crevices, the common source of air and moisture infiltration as well as temperature variations.

Closed-cell spray insulation, a rigid medium-density material, can be used in exterior applications such as continuous insulation applications, as well as interior applications. This type of foam insulation has a higher R-value per inch making it also suitable for small areas that require the highest possible R-value to meet building code requirements. Closed-cell spray foam’s rigidity help reject bulk water making it a recognized flood-resistant material by FEMA.
The Canadian National Building Code references the CAN/ULC S705.2 National Application Standard which must be followed during all installations of 2lb medium density closed cell polyurethane foam. Every installer of CAN/ULC-S705.1 compliant medium density, spray applied foam must be licensed in order to spray foam and hold valid photo ID issued by their Quality Assurance Program (QAP) provider showing their license is in good standing.

I am an Architect in Toronto. I am designing a new roof addition to a row house building. Because of existing conditions and the shape of the new roof. It may be easiest to use closed cell spray foam within the areas of the joists. My question is when spray foam is used in this situation do I need to worry about how the joist members may be thermal bridges? It is not common to provide a little bit of rigid insulation to protect the joist members? The additional layer of outboard insulation will require an extra layer of plywood above the insulation which will add to cost.

During colder months, 2 component foam is very sensitive to temperature variances. Per product instructions, both tank temperatures need to be above 70°F (21°C) for at least 24 hours prior to use. All application surfaces should be clean/dry and above 60°F (16°C) prior to application. Variance outside of the recommended temperature can affect foam yield and performance.

Roof coatings can add 25 years to the service life of a roof and reduce the amount of discarded roofing materials that end up in landfills. The infrared image on the right shows 175 °F (79 °C) on the uncoated (black) section of the modified bitumen roof. The coated (white) section is 79 °F (26 °C). Field studies have shown that cool roof coatings can lower rooftop temperatures and reduce air conditioning bills.

Was hesitant to buy this product because of some of the reviews but glad I did. It does just what it says and we even got the square footage out of it. You just need to read ALL the directions first and it wouldn't hurt to read some of the helpful hints in some of the reviews. It does only cover 1 inch at 600 square feet and is extremely easy to apply. Very satisfied customer!
EPDM (Liquid Roof), (Liquid Rubber) Ethylene Propylene Diene Monomer. Liquid Rubber is available in White, Black Or Grey. The RV product Liquid Roof is available only in white. However, you can customize the color by adding no more than three ounces per gallon of an universal colorant (Glycol Colorant for light colors and for medium to heavy colors use a solvent based colorant available at most paint stores). If the desired color is still not achieved you may add up to ONE more additional ounce of colorant. Once the colorant is added and color achieved then you add catalyst and mix and you are ready! The Liquid Roof coating is specifically designed for RVs and trailers and mobile homes; items that are in motion. Liquid Rubber, the commercial product, is available in white or black. Custom colors are available for orders over 100 gallons. Approved Uses for Liquid EPDM Rubber. http://www.youtube.com/v/ggLAUsiuI_o?version=3
Note:  A board foot is defined as a 12" x 12" square at 1" thick. Actual output can be affected by a number of factors including temperature and humidity. The theoretical yield has become an industry standard for identifying certain sizes of two component kits. Theoretical yield calculations are performed in perfect laboratory conditions, without taking into account the loss of blowing agent or the variations in application methods and types.

How Much Is Spray Foam Insulation Per Sq Ft


Spray foam is a very specialized packing material, often required for use in shipping valuable fragile items. Engineered packaging principles are designed to protect sculptures, vases, large fossils, lamp bases, busts, computers, furniture, chandeliers and other objects of unusual shape. By virtue of the liquid foam expanding by up to 30-60 times the volume of its liquid state, it efficiently protects almost any size, form and weight. http://youtube.com/watch?feature=youtube_gdata&v=ggLAUsiuI_o
Although spray polyurethane foam has many advantages over other types of insulation, spray foam installation isn’t foolproof. Some builders have reported problems with sloppy foam insulation. For example, some installers have been known to begin spraying before the chemical components are up to temperature, which can affect component mixing and foam performance. When components are poorly mixed, or mixed in the wrong ratio or at the wrong temperature, cured foam has been known to shrink away from rafters or studs, leaving cracks. Some installers rush through their spraying, resulting in voids.
When looking for a long-term roof solution, compare apples to apples. Liquid EPDM Rubber is a one-coat application. There are no primers needed, and when you begin adding up the cost of other systems that require primers and multiple coats, you are often exceeding the cost of liquid EPDM Rubber and have an inferior sealant on your roof. Why add unnecessary weight to a roof by using multiple-coat systems? Cut your time and labor costs in half with a one-coat system. Liquid EPDM has a very thick honey-like consistency and a slow cure time. One of the biggest benefits of the product. During the cure process, you will see bubbles resembling those created when you cook a pancake. This is the catalyst at work forcing the trapped air to the surface. What you have after the cure is a chemical bond between your roof and the coating. No other coatings produces this result. Other products trap this air making future cracks inevitable as temperatures change or expansion and contraction of the roof occur.
Loctite tite foam is a new generation of Loctite tite foam is a new generation of polyurethane-based insulating foam sealant that expands to fill seal and insulate gaps and cracks inside or out.
