What Quality Insulation Delivers

Lower Energy Bills, Greater Comfort, And Quieter Rooms

Insulation is the building envelope’s main defense against heat flow. Properly specified and installed materials slow conduction, control convection, and reduce radiant gains, translating into consistent indoor temperatures and fewer drafts. When paired with targeted air sealing, insulation can significantly lower heating and cooling loads while improving indoor sound levels.

Johnson Drywall provides end‑to‑end insulation services for new construction, additions, and retrofits. We assess assemblies—attics, walls, floors over garages, basements, and crawl spaces—to recommend the right R‑values, details, and materials for long-term performance and code compliance.

Selecting The Right Product For Each Area

We install fiberglass batts and blown‑in fiberglass for predictable R‑value and fast coverage. Dense‑pack cellulose delivers excellent cavity fill and sound control, with borate-only fire and pest treatment. Spray foam options include open‑cell for sound and air sealing and closed‑cell for high R‑per‑inch, vapor control, and added rigidity. Mineral wool adds fire resistance and moisture tolerance.

Methods are chosen to match your assembly: loose‑fill with rulers for attics, net‑and‑blow or dense‑pack for walls, flash‑and‑batt hybrids, and rigid foam for continuous exterior insulation to reduce thermal bridging. We follow manufacturer specifications, the IRC/IECC, and best practices for ventilation, baffles, and safe clearances around heat sources.

Detailed Evaluation, Precise Installation, Proven Results

Every project starts with a thorough assessment. We verify existing insulation levels, locate gaps with visual checks and optional thermal imaging, identify air leaks around penetrations, and review moisture conditions and ventilation. You receive a clear scope of work that aligns with budget, performance targets, and code requirements.

During installation we air‑seal critical joints, install vent baffles at eaves, set depth markers, and achieve uniform coverage and density. Penetrations are sealed, can‑light covers are used where appropriate, and safe clearances to flues and recessed fixtures are maintained. Our crews protect finishes, maintain a clean site, and provide documentation of materials and R‑values.

Where insulation is combined with drywall finishing, we set the stage for a durable surface. Primer is done before texturing to make it better quality, ensuring uniform absorption, improved adhesion, and a more consistent final appearance. This attention to detail complements the thermal upgrades for a well‑performing, great‑looking result.
