Are you tired of battling the Eastern Shore's fluctuating temperatures? Peninsula Insulation, LLC delivers top-tier spray foam insulation services in Delmar, MD, designed to optimize energy efficiency and indoor comfort. Whether you own a historic home near the Mason-Dixon line or manage a commercial agricultural facility, our solutions address the region's unique climate challenges. By creating a superior air seal, we help property owners drastically reduce HVAC load, eliminate drafts, and protect against the high humidity typical of Wicomico County. Experience a modernized building envelope that keeps your interior cool during humid summers and warm during crisp winters.
Living in Delmar means dealing with distinct weather patterns that test the limits of standard building materials. Traditional batting often settles or leaves gaps, allowing conditioned air to escape and moisture to intrude. Our approach focuses on total thermal resistance. By applying advanced polyurethane foam products, we create a monolithic barrier that adheres directly to the substrate. This process not only stabilizes indoor temperatures but also improves indoor air quality by blocking allergens and pollutants. From retrofitting attics to sealing rim joists, our team ensures every nook and cranny is fortified against energy loss.

The Problem: A homeowner in a Delmar bungalow noticed cupping of hardwood floors and a musty smell during the summer. The traditional fiberglass batt insulation in the crawlspace was sagging and wet due to rising ground moisture.
The Solution: Peninsula Insulation, LLC, removed the ruined fiberglass and performed a full crawlspace encapsulation. We installed a heavy vapor barrier on the floor and applied closed cell spray foam to the foundation walls.
The Result: The humidity levels in the crawlspace dropped by 45%. The "cupping" in the floors subsided, the musty odor vanished, and the homeowner reported a noticeable reduction in their cooling costs the very next month.
Don't let another season pass with high energy bills and uncomfortable drafts. Peninsula Insulation, LLC is ready to transform your property with high-performance insulation solutions.

Open cell foam is softer, less dense, and allows for some moisture permeability, making it great for sound dampening and interior walls. Closed cell foam is rigid, thick, and acts as a complete vapor barrier and structural enhancer, which is ideal for exterior walls and crawlspaces in humid climates like Delmar.
Yes, specifically closed cell spray foam. Creating an airtight seal prevents moisture-laden outdoor air from entering your home. This significantly reduces the load on your dehumidifier and AC unit, keeping indoor humidity levels comfortable.
Yes, we can often use "Injection Foam" or blown-in cellulose/fiberglass for existing walls. However, for spray foam, we typically require open wall cavities. We can assess your specific situation to recommend the least invasive retrofit option.
Spray foam insulation is a long-term solution. Unlike fiberglass, which can sag or settle over time, spray foam adheres to the building structure. It maintains its shape and R-value for the life of the building, effectively lasting indefinitely without needing replacement.
Absolutely. Spray foam is the preferred method for agricultural buildings because it adheres directly to the metal shell. This prevents condensation (sweating), which can damage crops or equipment, and it strengthens the overall structure against wind.
