Wall Insulation

Wall Insulation

Your walls are the largest surface area for energy loss. We ensure your exterior walls are fully insulated to prevent thermal transfer, keeping your living space warm in winter and cool in summer.
Metal Building Insulation

Metal Building Insulation

Metal conducts heat rapidly, making uninsulated metal buildings unbearable. We install systems specifically designed to break that conductivity, preventing condensation and making the space usable year-round.
Mineral Wool Insulation

Mineral Wool Insulation

For areas requiring high fire resistance and acoustic control, mineral wool is superior. It withstands extremely high temperatures without melting and effectively blocks sound, making it ideal for utility rooms and firewalls.
Insulation Removal

Insulation Removal

Rodent droppings, mold, or water damage can contaminate old insulation. We safely extract and dispose of compromised materials, cleaning the cavity to ensure a healthy substrate for new installation.
Air Sealing

Air Sealing

Insulation works best when air isn't moving through it. We systematically hunt down and seal gaps around pipes, vents, wires, and windows to stop conditioned air from leaking out and unconditioned air from seeping in.
Commercial Roof Coatings

Commercial Roof Coatings

Specifically designed for the rigors of commercial flat roofs. These elastomeric coatings form a seamless, waterproof membrane over the existing roof, extending its service life and reflecting solar heat to reduce cooling costs.
Floor Insulation

Floor Insulation

Cold floors can make a whole house feel chilly. We insulate between floor joists over unconditioned spaces, such as garages or vented crawlspaces, to keep your floors warm and comfortable underfoot.

Mini Case Study: Solving Ice Dams in Plainfield North

The Challenge: A two-story home in the Plainfield North subdivision was suffering from severe ice dams every winter. The homeowners were dealing with water damage on the second-floor ceilings and dangerously large icicles hanging from the gutters.

The Solution: Upon inspection, we found significant air leakage from the living space into the attic and insufficient fiberglass insulation. We performed a "remove and replace" operation. We extracted the old insulation, air-sealed all penetrations (light fixtures, plumbing stacks), and installed blown-in cellulose to R-60.

The Result: The air sealing stopped warm air from escaping into the attic, preventing the snow on the roof from melting and refreezing. The ice dams disappeared completely, the upstairs became comfortable again, and the client reported a 20% drop in heating costs.

Frequently Asked Questions (FAQs)

What is the most effective insulation for Plainfield winters?

For our climate, Closed Cell Spray Foam is often the most effective because it provides the highest R-value per inch and acts as a vapor barrier and air sealer, preventing heat loss common during freezing Illinois winters.

How do I know if my home is under-insulated?

Common signs include fluctuating temperatures between rooms, cold walls to the touch, high energy bills, drafts near outlets, and ice dams forming on your roof gutters during the winter.

Can insulation help reduce noise from outside?

Yes. Open Cell Spray Foam, Cellulose, and Mineral Wool are excellent at sound dampening. They absorb sound waves, significantly reducing noise from traffic, neighbors, or wind.

Is spray foam insulation safe for my family?

Yes, when installed by certified professionals. We use high-quality materials and ensure proper ventilation during application and curing. Once cured, the foam is inert and safe for occupants.

Do you offer insulation removal services?

Yes. If your existing insulation is damaged by water, mold, or pests, we can safely remove it using commercial vacuums and prepare the space for clean, new insulation.

How long does an insulation retrofit take?

Most residential retrofit projects, such as attic insulation or rim-joist spraying, can be completed in 1 to 2 days. Larger commercial projects will vary based on square footage.

What is R-Value and why does it matter?

R-Value measures a material's resistance to heat flow. The higher the R-Value, the greater the insulating power. In Plainfield, we aim for higher R-Values in attics and walls to combat the extreme temperature differences.

Will insulating my crawlspace help my floors feel warmer?

Absolutely. Encapsulating and insulating the crawlspace prevents the cold earth temperature from transferring to your floorboards, making your home feel much warmer underfoot.

Can you insulate a finished wall without tearing it down?

Yes. We use "drill-and-fill" techniques, drilling small holes in the exterior or interior wall and injecting loose-fill insulation or injection foam, then patching the holes, leaving the wall intact.

Does your company handle commercial roofing insulation?

Yes. We specialize in Spray Foam Roofing and Commercial Roof Coatings, which insulate the roof deck and provide a seamless, waterproof barrier for commercial buildings.
