You can feel it every winter: that cold draft sneaking through the walls, around outlets, and under doors. In Easton and surrounding areas, air sealing services from Peninsula Insulation, LLC help homeowners block these leaks for good. By closing gaps and sealing cracks, you gain better comfort, lower energy bills, and a healthier home environment—all while reducing strain on your heating and cooling systems. This small improvement makes a big difference for your household and for the region’s energy future.
Air leaks make heating and cooling systems work harder, pushing energy costs higher month after month. Air seal insulation stops that waste at the source. Whether you’re working on a new build or updating an older structure, sealing off gaps with spray foam, caulk, weather stripping, and foam gaskets delivers immediate improvements.
Spray polyurethane foam forms an expanding barrier, ideal for larger gaps and hard-to-reach spots. Caulk and weather stripping are perfect for windows, doors, and wall joints. Foam gaskets add insulation behind electrical outlets and switch plates. These materials work together to stop airflow and control interior temperatures more effectively year-round. For even more robust temperature control, many Easton homeowners also upgrade to blown-in insulation after sealing air leaks, especially in attic and wall cavities.
Benefits:
Air sealing insulation works best when applied in the right places. Common leak zones include attics, basements, crawl spaces, and wall joints. Garages and utility rooms also often allow unwanted air exchange. Precision sealing in these zones delivers the greatest impact.
Peninsula Insulation, LLC uses proven materials like spray foam and caulk to address air leaks without unnecessary removal or demolition. Foam gaskets and weather stripping provide clean finishes for more visible areas. Combined, these materials offer a comprehensive solution that improves every corner of the building envelope.
Applications:
Every air sealing project starts with a careful inspection. Trained technicians locate points of air leakage using visual checks and pressure diagnostics. Once areas are identified, the best sealing method is selected based on the size and accessibility of each gap.
Open cell spray foam is applied where larger openings exist, often in attic flooring or around vent pipes, thanks to its ability to expand and fully fill irregular spaces. Caulk handles narrow gaps around trim and fixtures. Weather stripping works well around door and window frames. The process is efficient and minimally invasive, offering real improvements without major disruption to your space.
Things to Consider:
Air leakage doesn't just affect comfort—it compromises the entire structure over time. Air barrier installation protects building materials from moisture, mold, and thermal stress. It also supports long-term durability by reducing the strain on HVAC systems and internal components.
Installing air barriers as part of new construction or retrofitting older buildings extends building lifespan and reduces maintenance needs. Polyurethane spray foam, in particular, provides both air sealing and insulation, serving a dual role in thermal and moisture defense.
Quick Comparison Table:
Material | Best For | Durability |
Spray Foam | Large gaps, irregular surfaces | High |
Caulk | Small joints, interior trim | Moderate |
Weather Stripping | Doors, windows | Moderate-High |
Foam Gaskets | Outlet covers, switch plates | High |
In Easton, seasonal weather swings create serious energy demands. Drafts in winter and heat intrusion in summer lead to constant system cycling. Local homes benefit from air sealing not just for comfort, but to meet growing interest in energy efficiency and lower carbon impact.
With heating oil and electricity prices on the rise, more homeowners are prioritizing upgrades that reduce long-term energy use. Air sealing is one of the fastest and most affordable ways to do that. It’s a smart choice for both older homes and new construction, helping meet energy codes and reduce emissions.
