From assessment to installation, Mr Hemp House™ delivers GaiaCrete® hemp insulation engineered for Janesville's unique heat challenges.
Janesville, Wisconsin faces some of the most demanding insulation conditions in the country: freeze-thaw cycling, ice dams, summer humidity, and dramatic temperature swings. GaiaCrete® manages all four seasons with a single system — thermal mass for winter heating savings, breathable walls for summer moisture management, and pH 12+ mold prevention year-round.

Why Janesville homeowners are choosing GaiaCrete® and GaiaBlocs™ over conventional insulation — built for Wisconsin's real conditions.
Janesville experiences temperature swings from -20°F winters to 90°F+ summers — demanding insulation that performs across a 110°F range
Dramatic temperature swings in Janesville create condensation that destroys conventional insulation. GaiaCrete® manages moisture naturally
Janesville homes sealed against winter cold trap VOCs for months. GaiaCrete® releases zero VOCs, ensuring clean air year-round
The temperature differential between heated interiors and frozen exteriors creates hidden mold in Janesville homes. GaiaCrete® pH 12+ prevents this
Janesville's exposure to lake-effect snow and ice storms makes GaiaCrete® monolithic walls essential for eliminating drafts and cold spots
4+ hour fire rating without chemicals provides critical protection for Janesville homes and families
Wisconsin's climate creates specific insulation failures that most homeowners don't discover until damage is done. Here's what we see in Janesville homes.
The Problem: Extreme heat overwhelms R-value-only insulation. Conventional materials let heat radiate through walls, forcing HVAC to run nonstop.
The GaiaCrete® Solution: GaiaCrete®'s thermal mass absorbs heat during the day and releases it slowly, reducing cooling cycles by 30-50%.
The Problem: Trapped moisture in wall cavities leads to condensation, mold growth, and insulation degradation — often invisible until major damage occurs.
The GaiaCrete® Solution: GaiaCrete®'s vapor-permeable composition allows moisture to pass through naturally, preventing condensation without vapor barriers.
The Problem: Sealed homes trap VOCs from spray foam, formaldehyde from OSB, and chemical flame retardants — your family breathes these 24/7.
The GaiaCrete® Solution: GaiaCrete® releases zero VOCs and actively absorbs CO2, improving indoor air quality instead of degrading it.
| Feature | GaiaCrete® & GaiaBlocs™ | Spray Foam | Fiberglass |
|---|---|---|---|
| Mold Resistance | Impossible (pH 12+) | Traps moisture | Mold in 24-48hrs |
| VOC Off-Gassing | Zero — absorbs CO2 | 20+ years | Low but present |
| R-Value | 3.5-5 per inch | 6-7 per inch | 3.1-3.7 per inch |
| Fire Rating | 4+ hours, no chemicals | Burns with toxic smoke | Melts |
| AC Cost Reduction | 30-50% | 15-25% | 10-15% |
| Lifespan | 100+ years | 20-30 years | 15-20 years |
| Thermal Mass | Excellent — stores & releases | None | None |
Lab-tested at R-3.5-5.0 per inch. But GaiaCrete®'s real advantage is thermal mass — it absorbs and releases heat slowly, outperforming higher-R-value materials in real-world conditions.
Hidden toxins in conventional insulation affect thousands of WI families. Get a free assessment to understand your home's air quality and insulation health.
Many Janesville homes have ice dam damage, condensation in wall cavities, and mold growth that homeowners never see. Wisconsin's freeze-thaw cycles create moisture pathways that conventional inspections miss. Our assessment uses thermal imaging to reveal hidden moisture, failing insulation, and air leaks in your Janesville home.
Learn About Our AssessmentJanesville's four-season climate subjects insulation to extreme stress — from sub-zero winters to humid summers. Fiberglass loses up to 40% of its R-value when moisture accumulates during Wisconsin's freeze-thaw cycles. GaiaCrete® maintains consistent performance year-round because its hygroscopic nature manages moisture without degradation. Janesville homeowners see 30-50% lower heating costs in winter and comparable cooling savings in summer.
