Residential Spray Foam
Garage Insulation for Vegas Heat
An uninsulated attached garage acts like a solar oven that shares a wall with your living space. Spray foam on the walls and ceiling keeps that heat where it belongs, outside.

Overview
Why Garages Run So Hot in Southern Nevada
A garage with an uninsulated ceiling and walls can reach well above outdoor air temperature by mid-afternoon, and if that garage shares a wall or ceiling with air-conditioned living space, that heat load does not stay contained.
We spray foam garage walls, the ceiling below any living space above, and the door header area to cut heat transfer into the home. This is also the right project scope for anyone converting a garage into a workshop, gym, or bonus living space.
- Cuts radiant heat transfer through shared garage walls and ceilings
- Improves comfort for garage workshops, gyms, and home offices
- Reduces HVAC load on rooms adjacent to or above the garage
- Adds sound dampening between the garage and living space
What's Included
Garage Insulation Scopes We Handle
Garage projects range from a single shared wall to a full conversion-ready envelope.
Shared Wall Only
Insulating just the wall(s) that separate the garage from conditioned living space.
Full Garage Envelope
Walls and ceiling insulated for garages being converted to livable or climate-controlled space.
Header & Door Trim
Sealing the framing around the garage door opening, a common overlooked leak point.
Workshop & Gym Conversions
Insulation scoped for garages being finished into a workshop, gym, or studio.
Ceiling Below Bonus Rooms
Insulating the garage ceiling when a bedroom or bonus room sits directly above.
New Construction Garages
Insulating garage walls and ceiling during the build, before drywall.
Why It Matters
The Shared-Wall Problem
Builders often insulate garages to a lower standard than the rest of the house, on the assumption the space is not conditioned, but that logic breaks down wherever the garage touches conditioned space.
Spraying just the shared assemblies is one of the most cost-effective ways to reduce heat gain into adjacent rooms without insulating an entire garage.
Our Process
How We Insulate a Garage
Most garage insulation projects are completed in a single visit.
Scope the Assemblies
We identify which walls and ceiling areas actually border conditioned space or need coverage.
Protect Vehicles & Storage
We help clear or mask off the work area to protect stored items from overspray.
Spray Application
Foam is applied to the agreed scope, shared walls, ceiling, header, or full envelope.
Trim & Finish-Ready
Foam is trimmed flush if drywall will be installed as part of a conversion project.
