The only floor insulation that can fight gravity, and win.
Spray foam insulation is often considered the best type of insulation for floors due to its unique ability to fight gravity and never sag. Unlike other types of insulation, such as batt or blown-in insulation, spray foam insulation adheres directly to the floor, filling every nook and cranny and creating an air-tight seal that prevents heat loss and air leaks. Because spray foam insulation is a closed-cell foam, it is resistant to sagging and settling over time, which means it will maintain its insulating properties for the life of the building. This is particularly important for floors, which are subject to constant weight and pressure from above. By using spray foam insulation, homeowners can enjoy a comfortable, energy-efficient living space with the peace of mind that comes from knowing their insulation will never sag or lose its effectiveness.
Cottage Conversions
Closed cell spray foam insulation is widely considered the best option for insulating the floor of a raised cottage during a conversion from 3-season to 4-season. This is due to the insulation’s superior insulation properties, air sealing abilities, moisture resistance, and pest resistance. Closed cell spray foam insulation tightly adheres to the floor, filling every gap and creating an airtight seal that prevents heat loss and drafts from below. The insulation’s high R-value ensures that heat is trapped inside the living space, reducing energy consumption and utility bills. Closed cell spray foam insulation is also highly resistant to moisture, which is particularly important for raised cottages that are prone to moisture damage. Additionally, closed cell spray foam insulation is resistant to pests such as rodents, insects, and termites, providing an additional layer of protection against potential damage. This makes closed cell spray foam insulation an excellent investment for homeowners looking to convert their raised cottage to a year-round dwelling.
Better Insulation & Stronger Floors
In some cases, spray foam insulation installed under the floor can prevent creaking floors. Creaking floors are often caused by the movement of the subfloor or floor joists as people walk across the floor. This movement can cause gaps to form between the subfloor and the joists, which results in creaking or squeaking sounds. However, when spray foam insulation is installed under the floor, it adheres tightly to the subfloor and the joists, filling any gaps and creating a rigid, solid connection between them. This prevents movement between the subfloor and the joists, effectively eliminating the source of the creaking. Additionally, because spray foam insulation provides excellent sound insulation, it can help to muffle any remaining noise and create a more peaceful living environment.
