How to Safely Apply Spray Foam Insulation

Spray foam insulation consistently outperforms all other types of insulation. Unfortunately, while effective at both insulating and sealing, polyurethane spray foam does have ingredients that can cause adverse health effects if not handled properly. These ingredients include isocyanates which can cause skin and eye irritation, asthma, lung damage, and other respiratory problems. Whether you are the applicator, a helper, or an occupant of the building being sprayed, there are several steps you should take to keep everyone safe. Applying the Spray Foam Insulation First, start by reading the product information for instructions on the application process, safety practices, precautions, and

The Different Types of Polyurethane Insulation

Polyurethane has a wide variety of applications ranging from cushioning in automobiles to construction materials. There are several different types of polyurethane insulation that can serve various purposes and needs. In this article, we’re going to take a closer look at a few types of polyurethane insulation and their uses. Spray Polyurethane Foam Spray foam is perhaps the best-known form of polyurethane insulation. The foam is composed of two chemical materials which expand to about 30 to 60 times their liquid volume when they are mixed. This makes them perfect to use when insulating irregularly shaped areas and hard to

How to Use Spray Polyurethane Foam

Spray Polyurethane foam is a great way to seal cracks, small crevices or holes in your home. You can get small aerosol cans of spray foam sealant at most hardware stores. They are designed for the homeowner in mind and are easy to apply. For larger jobs, there are two component, low-pressure spray polyurethane kits. However, these kits are more complicated to use and require more care and exactness in the application process. The process is based on four guiding principles: Wear protective gear Warm the tanks  Shake the tanks  Clean/change the nozzle regularly Wearing Protective Gear Spray polyurethane foam

What is Polyurethane Foam?

Back in 1937, the initial research on polyurethane polymers started in Germany. Researchers focused mostly on producing flexible fibers and foams. However, the product that we know today as polyurethane foam (PU foam) did not become available for commercial production until 1954. The production process for polyurethane foam usually involves adding small amounts of blowing agents (which are volatile) to chemicals. This reaction will result in a lower density, higher energy absorption, and an increase in thermal insulation to the base material. The blowing agents aerate the base chemical, similarly to how baking soda aerates bread. The process of producing
