• Attics & Roof Decks: Eliminate air leaks and improve comfort year-round.

🏗️ Pole Barn Insulation — Done Right

Wisconsin weather is brutal on uninsulated barns and ag buildings. Spray foam insulation transforms pole barns from damp and drafty to dry and efficient. Whether you're storing equipment, housing animals, or building a hobby shop, we provide a tight thermal envelope that lasts.

• Closed-cell foam for superior moisture and vapor control
• Strengthens the structure and resists pests and mold
• Reduces condensation on metal panels
• Makes barns usable year-round, no matter the weather
• Fast application on new builds or retrofits

We’ve insulated dozens of barns in the Madison region — from Verona to Sun Prairie. If you want reliable performance with a clean install, Green Peak is your crew.

🦠 Mold Prevention & Moisture Control

Madison homes face year-round moisture issues — from snowmelt in winter to humid basements in summer. Closed-cell spray foam insulation prevents mold by blocking vapor, sealing gaps, and stopping the moisture cycle before it starts.

We’ve helped homeowners across Dane County eliminate mold-prone areas with foam in crawl spaces, rim joists, and rooflines. If you've had a mold issue in the past, spray foam is your best long-term defense.
