Frequently Asked Questions

Blown-in insulation fills irregular spaces and gaps more completely, while batt insulation comes in pre-cut panels designed for standard framing. Blown-in is ideal for attics and retrofits, whereas batts work well in new construction with uniform cavities. At Apollo Insulation, we help Winthrop homeowners choose based on their specific application and building structure.

Spray foam expands upon application to fill cracks, gaps, and voids in building structures, creating an airtight barrier. This expansion seals areas that other insulation types can't reach, preventing drafts and air leakage. It's particularly effective in rim joists, around windows, and in irregular spaces.

Old insulation should be removed if it's water-damaged, contaminated by pests, or severely compressed and ineffective. Removal also makes sense when upgrading to a different insulation type that requires a clean surface. At Apollo Insulation, we assess existing conditions during energy audits to determine if removal is necessary.

Yes, attic insulation significantly reduces heating costs in Maine's cold climate by preventing warm air from escaping through the roof. Heat naturally rises, and without adequate attic insulation, up to 25% of heating energy can be lost. Proper attic insulation is one of the most cost-effective energy improvements for Winthrop homeowners.

An energy audit identifies air leaks, insulation gaps, thermal bridging, and areas where conditioned air escapes from your building. It uses diagnostic tools to pinpoint energy waste throughout the structure. At Apollo Insulation, we provide tailored insulation solutions based on audit findings to maximize efficiency.

Air sealing eliminates drafts and prevents conditioned air from escaping before insulation can do its job. Even the best insulation loses effectiveness if air flows freely through gaps and cracks. Combining air sealing with insulation creates a complete building envelope that maximizes energy savings and comfort.

Yes, roll insulation can be installed in crawl spaces, typically between floor joists or against walls. However, crawl spaces often require moisture control measures alongside insulation to prevent mold and degradation. At Apollo Insulation, we evaluate crawl space conditions to recommend the most appropriate insulation type and moisture barrier solutions.

The biggest mistake is adding insulation without addressing air leaks first. Air sealing should come before insulation installation, as gaps and cracks allow conditioned air to bypass insulation entirely. Many homeowners also compress insulation during installation, which reduces its R-value and effectiveness.

Crawl space insulation prevents cold air from entering through floors, reducing drafts and making living spaces more comfortable. Uninsulated crawl spaces allow heat loss and moisture intrusion, which can lead to cold floors, higher energy bills, and potential structural issues. Proper insulation and moisture control create a healthier, more efficient home.

Commercial insulation is installed to specific R-values and coverage requirements outlined in state and local energy codes. Proper insulation reduces operational costs and ensures compliance during inspections. At Apollo Insulation, we stay current on Maine energy code requirements to help commercial clients meet standards while maximizing efficiency.

Cost depends on the area size, desired R-value, accessibility, and existing insulation removal needs. Attics are typically less expensive than wall retrofits due to easier access. Material type, whether cellulose or fiberglass, also influences pricing, along with any air sealing work required beforehand.

Yes, insulation materials like blown-in cellulose and fiberglass batts absorb sound waves, reducing noise transmission between rooms and from outside. This soundproofing benefit is especially noticeable in walls and floors. At Apollo Insulation, we install insulation that improves both thermal performance and acoustic comfort for residential and commercial clients.
