Closed-cell spray foam acts as a built-in vapor barrier, which is essential for Newcastle's damp climate. It prevents moisture from condensing inside your walls, which helps inhibit mold growth and rot.
Yes. Unlike fiberglass, spray foam provides an airtight seal. In lakeside areas where wind and moisture are higher, spray foam stops air infiltration and won't lose its R-value if it becomes damp.
While it depends on the condition of the existing material, we often recommend removing old, contaminated insulation to allow the spray foam to adhere directly to the substrate for a perfect seal.
Most residential projects, such as attic or crawl space insulation, can be completed in just one to two days, depending on the square footage and accessibility.
Absolutely. Open-cell spray foam is particularly effective at dampening sound, making it a great choice for homes near busy areas like Coal Creek Parkway.
Once cured, spray foam is inert and does not off-gas. It actually improves air quality by preventing outdoor pollutants, allergens, and dust from entering through cracks in the building envelope.
