What R-value does your climate zone require for attic insulation?

Most moderate climates require R-38 to R-49 in attics to meet current energy codes, which translates to roughly 12 to 16 inches of blown fiberglass or cellulose, though older homes often have half that amount or less from original construction decades ago.

How does air sealing differ from adding insulation, and why does sequence matter?

Air sealing stops convective heat loss by blocking pathways where air physically moves between conditioned and unconditioned spaces, while insulation slows conductive heat transfer through materials, and sealing must happen first or air movement will bypass the insulation layer entirely and negate most of its R-value benefit.

Why does old insulation need removal rather than adding new layers on top?

Compressed, wet, or contaminated insulation loses its ability to trap air pockets that provide thermal resistance, and adding weight on top compresses lower layers further while moisture or contaminants continue degrading performance and creating air quality issues inside the home.

What determines whether spray foam or blown insulation works better for your project?

Spray foam excels in wall cavities, crawl spaces, and areas requiring air sealing combined with insulation, while blown products cost less for large attic areas and allow easier access to roof decking for future repairs, making choice dependent on location and whether air sealing is the primary concern.

When should wall insulation be upgraded in existing homes?

Wall upgrades make sense during exterior siding replacement when cavities become accessible, when rooms stay consistently uncomfortable despite adequate attic insulation, or during major remodels when walls are opened, since dense-pack cellulose can be blown into closed cavities through small holes that get patched afterward.

Insulation | Kinetic Building Solution

Insufficient attic insulation can make it difficult to keep your home comfortable while driving up heating and cooling costs throughout the year. Kinetic Building Solutions installs blown-in, batt, and spray foam insulation throughout Kent, Isabella, Missaukee, Kalamazoo, and the surrounding West Michigan communities, helping homeowners improve energy efficiency, reduce utility expenses, and create a more comfortable indoor environment. With the right insulation levels and air sealing measures in place, your home can maintain more consistent temperatures during Michigan's seasonal weather extremes.

Every insulation project begins with an evaluation of your home's current insulation levels, energy performance, and potential sources of air leakage. Older insulation that has become compressed, damaged, or ineffective over time may be removed before new materials are installed. Air sealing around attic openings, recessed lighting, plumbing penetrations, and other common leak points helps prevent conditioned air from escaping and improves the overall effectiveness of the insulation system.

Homeowners throughout Kent, Isabella, Missaukee, Kalamazoo, and nearby communities often notice more even temperatures between floors, improved year-round comfort, reduced strain on HVAC equipment, and lower monthly energy bills after upgrading their insulation. Schedule an energy-efficiency evaluation today to identify opportunities for greater comfort, improved performance, and long-term savings in your home.

Blown-in cellulose or fiberglass fills irregular joist bays and surrounds obstructions that batt insulation bridges over, creating continuous coverage without the gaps that allow heat transfer through thermal bridging. Spray foam provides both insulation and air sealing in one application, expanding to fill cracks and voids while adding structural rigidity to wall assemblies.

After installation, your HVAC system cycles less frequently to maintain temperature, rooms that were previously too hot or too cold stabilize within a degree or two of the thermostat setting, and outside noise diminishes noticeably due to the sound-dampening properties of increased insulation density. Humidity levels inside the building become easier to control because air exchange rates drop when leaks around the building envelope are sealed before insulation installation.

The service includes ventilation assessment to prevent moisture accumulation in newly insulated attics, since adding thermal resistance without maintaining airflow can trap humidity that condenses on cold surfaces during winter. Crawl space insulation differs from attic approaches, using closed-cell spray foam on foundation walls in conditioned crawl designs or batt insulation between floor joists in vented configurations depending on your foundation type and moisture conditions.
