Key Differences
Fiberglass Insulation, constructed from fine glass fibers, is celebrated for its thermal insulating properties and ease of installation in various areas of buildings. Contrarily, Spray Foam Insulation, which is dispensed through a spray gun, expands upon application, forming a barrier that provides substantial thermal resistance and can seal gaps effectively.
Cost-wise, Fiberglass Insulation tends to be a more economical choice, making it a popular selection among residential and commercial property owners for its budget-friendliness. Alternatively, Spray Foam Insulation typically comes with a higher upfront cost due to its application method and potent thermal insulation properties.
When considering environmental and health impacts, Fiberglass Insulation mandates caution due to the minute glass shards and particles that may be released during its installation. On the opposite spectrum, Spray Foam Insulation, while mitigating air leaks and promoting energy efficiency, requires careful handling during installation to prevent undue exposure to its constituent chemicals.
