Spray foam insulation is a method of insulating and air-sealing using a spray application. The foam sprays on as a liquid and then quickly expands to fill and seal the cavity or surface in which it is applied into. This type of insulation that can be sprayed into walls, attics, crawlspaces as well as other hard to reach places around your home that need insulation. As it expands, it seeps into all the nooks and crannies to form a continuous air barrier, keeping you cooler in the summer and warmer in the winter.
Spray foam insulation creates a strong barrier against air leaks and heat transfer. By sealing gaps and cracks, it helps maintain consistent indoor temperatures, reducing the energy required for heating and cooling, which can lead to lower utility bills.
Spray Foam insulates and air-seals to control unwanted random air leakage – which traditional insulation can’t do without the use of extra sealing materials. Traditional insulation materials can also leave gaps and seams around electrical boxes or light fixtures (compromising performance). This is one of the great benefits of spray foam insulation, it fits perfectly around detailing to air-seal the space where it is applied.
While DIY kits are available, it is recommended to hire a professional installer. Proper application requires specialized equipment and knowledge to ensure safety and effectiveness.
Yes, spray foam insulation can help reduce noise transmission between rooms, making it a good choice for creating quieter indoor environments.
When professionally installed, spray foam insulation can last for the life of your building without needing replacement.
Signs that your home may benefit from spray foam insulation include drafts, high energy bills, uneven indoor temperatures, and difficulty maintaining comfortable humidity levels.
Spray foam helps to seal tiny cracks and penetrations that would otherwise allow unwanted airborne irritants to invade the living space such as outdoor allergens, pollutants, and humidity. Spray foam makes it easy to get a tight fit around wall openings, such as windows, electrical/cable service entry points, and light fixtures.
Most of the damaging moisture within a building envelope is the result of air movement through the cavities. When warm air meets a cold surface within a cavity, it condenses; and if not found in time, it can lead to mould and mildew. Spray foam creates continuously insulated, tight walls and ceilings to help minimize the potential for moisture, condensation and mould.
Certified spray foam installers wear protective gear, much like professional painters, to protect themselves from ‘overspray’ (small particles of material that become airborne during application) and to aid in breathing while working in confined spaces.
