Project Overview
This scope covers insulation installation in walls, attics, floors, crawlspaces, and around mechanical systems. It applies to residential and commercial projects using any common insulation type.
Typical Projects Include:
- New construction wall, attic, and floor insulation
- Attic insulation upgrade or top-off
- Spray foam insulation (open or closed cell)
- Crawlspace insulation and encapsulation
- Soundproofing insulation
- Pipe and duct insulation
Scope of Work
Planning
| Task | Description |
|---|---|
| Site Assessment | Inspect areas to be insulated. Note existing insulation, air gaps, moisture issues, and access points. |
| R-Value Specification | Determine required R-values for each area based on energy code and climate zone. |
| Material Selection | Select insulation type (batt, blown-in, spray foam, rigid board) based on application and budget. |
Installation
| Task | Description |
|---|---|
| Prep Work | Seal air leaks around penetrations, rim joists, and top plates before insulating. |
| Wall Insulation | Install insulation in exterior walls to specified R-value. Fill cavities completely without compression. |
| Attic Insulation | Install or blow in attic insulation to specified depth and R-value. Maintain required clearances around heat sources. |
| Floor / Crawlspace | Install insulation under floors or in crawlspace walls as specified. Secure properly to prevent sagging. |
Quality Check & Closeout
| Task | Description |
|---|---|
| Coverage Verification | Verify insulation is installed to required depth and R-value in all areas with no gaps or voids. |
| Inspection | Schedule and pass energy code inspection before drywall or other coverings are installed. |
| Cleanup | Remove all scrap material, packaging, and debris from the job site. |
Timeline & Milestones
Typical timeline for a residential insulation project. Larger commercial jobs may take longer.
| Phase | Duration | Description |
|---|---|---|
| Assessment & Planning | 1-3 days | Site inspection, R-value planning, and material ordering. |
| Installation | 1-3 days | Air sealing and insulation installation in all specified areas. |
| Inspection & Closeout | 1-2 days | Energy inspection and site cleanup. |
Roles & Responsibilities
Client / General Contractor
- •Provide access to all areas being insulated
- •Ensure framing, electrical, and plumbing are complete before insulation
- •Approve material selections and any scope changes
- •Process payments per the agreed schedule
Insulation Contractor
- •Supply and install all insulation materials

- •Meet all required R-values per energy code
- •Schedule and coordinate energy inspections
- •Clean up the job site after installation
Materials & Equipment
Insulation
- •Fiberglass batt insulation
- •Blown-in cellulose or fiberglass
- •Spray foam (open cell or closed cell)
- •Rigid foam board (XPS, EPS, or polyiso)
Air Sealing

Quality Control Standards
Energy Code R-Values
Insulation meets or exceeds R-value requirements for the climate zone.
Complete Coverage
No gaps, voids, or compressed insulation. Full contact with all surfaces.
Air Sealing
All penetrations and gaps sealed before insulation is installed.
Safety Protocols
Respiratory Protection
Wear proper masks or respirators when working with fiberglass, cellulose, or spray foam.
Skin & Eye Protection
Wear long sleeves, gloves, and safety glasses when handling fiberglass insulation.
Attic Safety
Use proper footing and lighting in attics. Watch for electrical wires and ensure adequate ventilation.
