Spray foam insulation fills gaps, crevices and corners to create a draft-free, comfortable living space. This reduces utility costs as heating and cooling systems do not have to work so hard to maintain a consistent temperature. It also improves indoor air quality, increases resale value and reduces outside noise. Go here: https://ssfinsulation.com/north-carolina-spray-foam-insulation/

There are two types of spray foam insulation: open cell and closed cell. The difference is that open cell foam has cells that aren’t completely encapsulated, making it a softer and more flexible material. Closed cell spray foam has cells that are pressed together and is more rigid than open cell foam.

Spray Foam vs. Traditional Insulation: A Comparative Guide

Both are sprayed into place and can be applied to any area of the home, including attics, crawl spaces, rim joists and new construction, pole barns and concrete block walls. Professionals use large rigs to spray the foam, which ensures consistency and expansion. They wear gloves, goggles, breathing apparatuses and full-body coverings to avoid exposure to the chemicals.

It’s a good idea for homeowners to vacate their homes during the spraying and curing process, typically about 24 hours. Proper ventilation is important afterward to allow the fumes to dissipate. Open windows and run fans in the room to vent outwards, but be sure not to ventilate too early. Ventilating too soon could impact how long it takes for the foam to fully cure and revert back to a solid state.

It’s important to choose a spray foam insulation installer with a good reputation and extensive experience in residential insulation. Many DIY kits are available for people who want to install spray foam themselves, but getting consistent coverage and expanding the foam properly requires significant prior experience and training.
