Insulation & Thermal Envelope
Seal the gaps, insulate the boundaries, and keep conditioned air where it belongs — inside your building.
❌ The Problem
You're heating and cooling the outdoors. Air leaks around windows, doors, attics, and rim joists let conditioned air escape and outside air infiltrate, making your HVAC system work harder than it should.
✅ Our Solution
We identify and seal air leakage paths with blower door testing, then upgrade insulation to proper R-values. The result: your HVAC system runs less, your comfort improves, and your bills drop.
Everything You Get
Quantify your building's air leakage rate and identify problem areas.
Infrared cameras reveal hidden insulation gaps and thermal bridges.
Seal penetrations, gaps, and bypasses throughout the building envelope.
Spray foam, blown-in cellulose, fiberglass, or rigid foam as needed.
Vapor barriers and ventilation to prevent moisture problems.
Follow-up blower door test to confirm improvement.
Why Choose Thermoline
20-40% Energy Savings
Reducing air leakage and upgrading insulation is often the highest-ROI improvement you can make.
Consistent Temps
No more drafty rooms, cold floors, or rooms that are always too hot or cold.
Noise Reduction
Better insulation and air sealing also significantly reduces outside noise.
Common Questions
What type of insulation is best?
It depends on the application. Spray foam excels at air sealing and tight spaces. Blown-in cellulose is cost-effective for attics. We recommend the right material for each specific area.
How do I know if I need more insulation?
Signs include drafty rooms, ice dams, high energy bills, and rooms that are hard to heat or cool. Our energy audit with blower door testing gives you exact data.
Will insulation cause moisture problems?
Not when done correctly. We always address moisture management as part of any insulation project, including proper vapor barriers and ventilation strategies.
