Understanding Spray Foam Insulation

When it comes to choosing a type of insulation a Koala expert can help you find the right choice. However, a great option is spray foam insulation. Spray polyurethane foam (SPF) is a spray-applied plastic that is widely used to insulate buildings and seal cracks and gaps, making the building more energy-efficient and comfortable. SPF insulation is known to resist heat transfer extremely well, and it offers a highly effective solution in reducing unwanted air infiltration through cracks, seams, and joints. 

Energy Efficient Benefits  

As much as 40% of a building’s energy is lost due to air infiltration. Gaps, holes and air leaks can make energy bills extremely high. Spray foam performs as both insulation and an air barrier, closing gaps that let air escape and add dollars to monthly energy bills. As much as half of the energy used in a home goes to heating and cooling, according to EPA1 . Maintaining an optimal heating, ventilating, and air conditioning (HVAC) system can make your home more energy efficient. With spray foam, HVAC sizing can be reduced as much as 35%. 2 Air leaks that can waste energy and drive up utility bills can be filled with spray foam.  

Types of Spray Foam 

Mixed on-site, spray foam is sent through a hose into the stud cavity, where it hardens and creates a long-term barrier that helps keep heat out in the summer -- and in, in the winter.  Depending on your needs, you will choose either open or closed cell spray foam.  

The benefits of closed cell are that it can actually strengthen walls and has low vapor permeance, while open-cell spray foam accommodates natural, slight building shifts, and is ideal in rooms where sound-reduction is desired, such as in home theaters or, for a light sleeper, bedrooms. Spray foam can be equally useful for condos, apartments, and townhomes to help reduce the noise between units.
