Sound Reduction

Unfinished Basements
Insulate accessible basement walls for comfort and open ceiling cavities for sound reduction before drywall is installed.
Attic Insulation
Evaluate existing attic insulation, identify thin or uneven areas, and improve comfort and thermal performance.
Drill-and-Fill
Insulate empty wall cavities and finished ceiling cavities through planned access openings without removing the entire surface.
Additions & Remodels
Coordinate insulation for new rooms, opened assemblies, finished spaces, and transitions between the existing home and new construction.
New & Custom Homes
Insulation scopes for owner-builders, custom homeowners, and smaller residential teams that value clear coordination.
Could your insulation project qualify for a utility rebate? Some attic, exterior-wall, and floor projects may qualify through current Utah utility programs. Requirements should be checked before installation.
Not sure which service applies?
Start with the condition of the space
The installation method changes depending on whether the framing is open, the drywall is finished, or the attic is accessible.
Open framing
Unfinished walls and open ceiling joists provide direct access for thermal insulation, basement ceiling sound reduction, or both before drywall.
Attic floor
Existing depth, distribution, air pathways, moisture, ventilation, and safe clearances guide the recommended insulation plan.

Describe the problem, not just a product
Tell us what part of the home is involved and what you want to improve.
You do not need to choose a material or installation specification before asking. Include the city, open or finished condition, approximate dimensions, photographs or plans, and timing if you know them. Interwest will recommend the approach and identify any additional details needed.
The project-specific estimate will define the treatment area, material, installation specification, preparation, finish responsibilities, cleanup, price, and timing.
