Spray Foam Insulation
Open-cell and closed-cell spray foam insulation provides exceptional air sealing and thermal performance for many residential and commercial applications. Spray foam is commonly installed in exterior walls, crawlspaces, rim joists, garages, additions, workshops, pole barns, and commercial buildings where improved energy efficiency and air sealing are priorities.
Attic Insulation
Many homes in Portage can benefit from additional attic insulation. We install blown-in cellulose and fiberglass insulation while also evaluating attic ventilation and air leakage. Proper attic insulation can help improve comfort, reduce drafts, and lessen the workload on your heating and cooling system.
Crawlspace Insulation
Uninsulated crawlspaces often contribute to cold floors, uncomfortable living spaces, and unnecessary energy loss. We install crawlspace insulation solutions designed to improve comfort while helping reduce unwanted air movement and moisture concerns where appropriate.
Fiberglass Insulation
Fiberglass batt insulation remains an excellent option for new construction, additions, garages, finished basements, pole barns, and commercial projects. Proper installation is essential, and our team carefully fits each batt to maximize insulation performance.
Insulation Removal
Old, damaged, or contaminated insulation may no longer perform as intended. Greenshield safely removes existing insulation when necessary before installing upgraded insulation systems that better meet today’s energy efficiency standards.

Our clients are our top priority. Here’s what they say.

Insulation problems are not limited to the attic. Cold floors can originate around crawlspace walls and rim joists, while older exterior walls may contain little insulation or none at all. Damaged or contaminated attic insulation may also need to be removed before improvements are made.
Greenshield offers crawlspace insulation, rim-joist spray foam, drill-and-fill sidewall cellulose and insulation removal throughout Portage. We evaluate each area separately and recommend the work most relevant to the home instead of assuming every property needs a complete replacement.

Adding insulation alone may not correct every attic-performance problem. Openings around electrical wiring, plumbing penetrations, wall top plates and attic access points can allow conditioned air to escape into the attic.
Greenshield evaluates accessible air leaks before installing additional insulation. We also check whether soffit vents need baffles to keep insulation out of the ventilation path. The correct combination of insulation, air sealing and ventilation can provide more consistent performance than simply adding material over existing problems.
