Spray foam insulation contractors are licensed professionals who specialize in mixing and applying polyurethane foam directly into walls, attics, and crawl spaces. The liquid expands and hardens into a dense material that creates an airtight barrier, significantly reducing energy losses and preventing moisture buildup.
However, applying spray foam involves a complex chemical reaction and requires specialized equipment, so it is not a DIY job. Here is the breakdown of why you need to hire professional spray-foam insulation contractors.
Proper Chemical Reactions
Spray foam insulation is made from polyurethane, a plastic polymer formed by mixing two main liquid components: isocyanate and a polyol resin. When sprayed together, these chemicals react and expand rapidly to form a dense and insulating foam that seals gaps.
However, mixing these volatile chemicals requires specialized knowledge and experience, as an improper ratio or a temperature deviation can cause lingering toxic odors. Furthermore, the foam will not fill gaps effectively and may cause structural damage to your property. This is why it is essential to hire a spray foam insulation contractor to ensure an effective and safe application.
Specialized Equipment
Spray foam insulation requires a specialized setup of machinery, hoses, and personal protective equipment. However, these heavy-duty systems are not available for standard consumer rental. Further, they also require specialized training and experience to operate this machinery effectively. This is where a professional spray foam insulation contractor can help.
As discussed earlier, spray foam insulation is a technical task that requires specialized skills and knowledge of the equipment. DIY might cause structural damage or health issues if foam fumes are inhaled for extended periods.
Safety and PPE
Spray foam is made of polyurethane foam containing isocyanates and polyol resin, which can cause severe respiratory, eye, and skin irritation or allergic reactions if the foam is not fully cured. Professional spray foam insulation contractors wear proper Personal Protective Equipment (PPE) to prevent all skin exposure and inhalation during application and trimming.
However, spraying without PPE and ignoring safety protocols can damage your property and expose you to serious health risks.
Expansion & Overspray Control
Spray foam expands rapidly. An amateur often oversprays areas that should not be sprayed or leaves gaps that compromise thermal efficiency. Over-spraying can leave a lot of foam debris everywhere, which may require thorough cleanup once the isolation application is complete. Cleaning up can be more difficult if the foam fumes have been dispersed throughout your space.
A professional spray foam contractor knows exactly how to protect your existing fixtures and completely seal the envelope. Therefore, to avoid the mess of cleaning your space, it is recommended that skilled professionals do it.
Code Compliance & Building Science
Professional spray foam contractors have a deeper understanding of building science, including where to use open-cell spray foam and where to optimize closed-cell spray foam. They also know local code compliance and energy codes to avoid moisture or mold traps in your walls or attic. Hiring a spray foam insulation contractor can help ensure your insulation complies with building codes.
