Spray foam for walls, ceilings, and garage doors
Convert your garage into a workshop, gym, or home office
Closed-cell foam provides thermal + moisture + air barrier
Address rim joists and penetrations between garage and living space
Ideal for ADU conversions and heated garage projects
A proven, methodical approach refined over 20+ years of professional installation.
We evaluate your garage's current insulation, shared walls/ceilings with living space, and your goals — whether energy savings, conversion, or comfort.
We determine the optimal insulation approach for walls, ceiling, and garage door, then prepare surfaces and mask off areas as needed.
Spray foam is applied to walls, ceiling, rim joists, and penetrations, creating a continuous thermal envelope that eliminates cold spots and air leaks.
We clean up the work area and walk you through the completed installation, answering any questions about finishing or next steps.
In Denver's climate, an uninsulated attached garage acts as a massive cold sink during winter — radiating frigid air through shared walls, ceilings, and floors into your living spaces. With temperatures regularly dropping below zero degrees, that cold transfer can account for significant energy loss and create uncomfortable rooms adjacent to the garage. Sky Insulation provides professional garage insulation using spray foam for walls, ceilings, and garage doors. Whether you want to reduce energy loss from an attached garage, create a heated workshop, convert your garage into a home gym or office, or build an ADU (Accessory Dwelling Unit), proper insulation is the foundation for a comfortable, energy-efficient space. Our crews insulate garage walls, shared walls and ceilings, and garage doors using closed-cell or open-cell spray foam tailored to your specific goals. We also address the rim joists and penetrations between the garage and living space that are common sources of drafts and air leakage.

Insulating your attached garage prevents cold air from radiating into adjacent living spaces, reducing your heating bills during Denver's harsh winters.
A properly insulated garage stays warmer in winter and cooler in summer — making it usable as a workshop, gym, or office year-round.
Spray foam fills every gap in walls, ceilings, rim joists, and penetrations — creating a seamless barrier that batt insulation can't match.
Most garage insulation projects are completed in a single day, minimizing disruption to your routine.






Yes — especially if your garage is attached to your home. Uninsulated attached garages are one of the biggest sources of energy loss in Denver homes, and insulating them reduces heating costs and improves comfort in adjacent rooms.
Yes. We can apply insulation to garage doors to reduce heat transfer. For the best results, we recommend insulating the garage walls, ceiling, and door together for a complete thermal envelope.
Closed-cell spray foam is the best option for most Denver garages because it provides thermal insulation, air sealing, and moisture resistance. For budget-conscious projects, open-cell spray foam or batt insulation can also be effective.
Most residential garage insulation projects are completed in one day. Larger or more complex projects may take two days.
