Materials & air control
Spray foam insulation
Spray foam insulation creates a continuous layer across cavities, rooflines and framing transitions where conventional materials can be difficult to fit closely. Depending on the assembly, access and performance goal, open- or closed-cell foam may be considered to combine thermal resistance with air-control benefits. Careful preparation and controlled application are essential for consistent coverage around penetrations, irregular framing and other common weak points.
- Irregular framing
- Rooflines
- Rim joists
Materials & air control
Blown-in insulation
Blown-in insulation is well suited to attic floors and accessible cavities that contain tight corners, framing obstructions or an uneven existing layer. The loose-fill material is distributed to create more consistent coverage across the working area, including spaces that can be difficult to reach with rigid or batt products. Before installation, the assembly should be reviewed for access, ventilation, air-leakage paths and any existing material that may affect the finished result.

- Accessible cavities
- Top-ups
Materials & air control
Fiberglass batt insulation
Fiberglass batt insulation is a practical option for open framed walls, ceilings and floor assemblies where each piece can be measured and fitted directly into the cavity. Performance depends on a close installation around wiring, pipes, corners and framing rather than simply placing material between studs or joists. We assess cavity depth, spacing and surrounding conditions so the selected batt and installation method suit the assembly being insulated.
- Open framing
- Walls
- Floors and ceilings
Materials & air control
Air sealing
Air sealing focuses on the small gaps and transitions that allow uncontrolled air to move through the building envelope even when insulation is already present. Typical attention areas include utility penetrations, top plates, rim joists, attic bypasses and changes between materials. By identifying and sealing these pathways as part of the insulation plan, the thermal layer can work as a more coordinated system rather than being undermined by hidden leakage points.
- Penetrations
- Transitions
- Leakage paths
Residential & retrofit
Existing home insulation
Insulating an existing home requires a different approach from working with fully open new construction. Existing finishes, older materials, limited access and planned renovations all influence where improvements can be made and which methods are appropriate. We look at the home as it stands, identify practical opportunities within accessible assemblies and recommend targeted upgrades that improve the insulation and air-control layers without assuming every wall or ceiling can be opened.
- Retrofits
- Occupied homes
- Renovations
Residential & retrofit
Attic insulation
The attic is often one of the most important places to establish a clear thermal and air-control boundary. Work may involve the attic floor, roofline, eaves or transitions around mechanical and electrical penetrations, depending on how the space is built and used. We review existing insulation, access, ventilation and visible leakage paths before selecting an approach designed to create more consistent coverage across the overhead assembly.
- Rooflines
- Attic floors
- Eaves
Residential & retrofit
Wall insulation
Wall insulation helps form the thermal boundary around living and working spaces, but the right method depends on whether the framing is open, partially accessible or fully enclosed. Cavity depth, obstructions, existing material and the condition of the wall all affect the recommendation. The goal is consistent coverage that fits the available assembly while accounting for common interruptions around outlets, pipes, blocking and transitions to floors or ceilings.
- Open walls
- Enclosed cavities
- Additions
Residential & retrofit
Crawl space insulation
Crawl spaces can expose the underside of a home to outdoor temperatures, moisture conditions and uncontrolled air movement. An effective plan considers the floor assembly, perimeter walls, rim joists, penetrations and the way the crawl space currently communicates with the home above. We evaluate these connected areas before recommending insulation and air-sealing work intended to create a clearer, more continuous boundary beneath the occupied space.
- Perimeter walls
- Floors
- Rim joists
Residential & retrofit
Removal & replacement
Insulation that is wet, damaged, contaminated, heavily disturbed or poorly installed may need to be removed before the assembly can be improved. The process begins with protecting access routes and surrounding areas, then carefully clearing the affected material so the underlying surfaces can be seen. With the cavity or attic exposed, air-leakage paths and other visible conditions can be addressed before new insulation is installed in a cleaner, more deliberate system.
- Old material
- Damaged insulation
- Assembly reset
Commercial & specialty
Commercial insulation
Commercial buildings can include large open areas, mixed-use zones and assemblies that perform very differently from one part of the property to another. Insulation recommendations are shaped around the building type, access, occupancy needs and the specific wall, roof or ceiling system involved. We coordinate material selection and installation details around the project scope so thermal and air-control work fits the conditions of offices, workshops, warehouses and other commercial environments.
- Offices
- Workshops
- Warehouses
Commercial & specialty
Soundproofing insulation
Soundproofing insulation is used within interior walls, ceilings and floor assemblies to help limit sound transfer between adjoining rooms or occupied areas. The insulation layer is only one part of an acoustic assembly, so framing, penetrations, surface materials and flanking paths also matter. We match the insulation approach to the available cavity and project goal, whether the priority is greater privacy, quieter work areas or improved separation between residential spaces.
- Partitions
- Ceilings
- Floor assemblies
Commercial & specialty
Fireproofing paint
Intumescent fireproofing paint is a specialized coating designed for eligible structural elements where the specified system calls for a protective, finished surface. Correct application depends on the substrate, preparation, compatible primer, required coating build and project documentation. Because these systems are specification-driven, the product and installation method must be aligned with the component and the fire-protection requirements established for the project.
- Eligible steel
- Structural components
- Coatings
Commercial & specialty
Spray-applied fireproofing
Spray-applied fireproofing is used on eligible structural steel and other specified assemblies to provide a passive fire-resistive layer. The work requires suitable surface conditions, controlled application and attention to the thickness and coverage defined for the selected system. We approach these projects as specialized installations, coordinating the material and fieldwork with the documented assembly requirements rather than treating fireproofing as a general-purpose coating.
