Frequently Asked Questions

Get answers to questions homeowners ask about our insulation services

  • What preparation is required before spray foam installation? 

    You need to clear the work area of stored items and ensure electrical and plumbing rough-ins are completed, since foam application happens after framing inspection but before drywall installation in new construction or after removal of existing wall coverings in retrofit projects.

  • How does closed-cell foam differ from open-cell foam in performance?

    Closed-cell foam provides a higher R-value per inch and acts as a vapor barrier, making it suitable for exterior walls and unvented attic assemblies, while open-cell foam costs less per board foot and performs well in interior applications where vapor permeability is acceptable.

  • When is the best time to schedule insulation upgrades?

    Late spring through early fall offers the most favorable curing conditions in Cuba, though controlled indoor environments allow installation year-round as long as surfaces are dry and temperatures remain above the manufacturer's minimum application threshold.

  • What areas of a home benefit most from spray foam?

    Rim joists, cathedral ceilings, and attic rooflines see the greatest improvement because these areas typically have the most air leakage and are difficult to insulate effectively with traditional methods.

  • How long does spray foam take to cure fully?

    Open-cell foam cures within hours, while closed-cell foam may take up to 24 hours to reach full hardness, after which the space can be occupied without concern about off-gassing or surface stickiness.
