- Minimum R-value requirements
- Air sealing mandates
- Fenestration standards
Local Amendments:
- State-specific requirements
- Climate zone adjustments
- Utility company standards
- Municipal ordinances
Long Island Requirements
Climate Zone 4:

- Walls: R-13 to R-20
- Floors: R-13 to R-30
- Continuous insulation requirements
Insulation Timing in Construction
Pre-Insulation Phase
Foundation work:
- Install foundation insulation
- Set up drainage systems
- Prepare for below-grade barriers
- Coordinate with concrete work
Framing Phase
Wall insulation:
- Install between wall studs
- Add vapor barriers
- Coordinate with electrical/plumbing
- Prepare for drywall
Roof Phase
Attic insulation:
- Install after roof sheathing
- Coordinate with HVAC rough-in
- Ensure proper ventilation
- Prepare for ceiling finish
Modern Insulation Methods
Continuous Insulation
Exterior rigid foam:
- Installed on exterior side of framing
- Provides continuous thermal barrier
- Reduces thermal bridging
- Meets code requirements
Structural Insulated Panels (SIPs)
Factory-built panels:
- Walls and roofs pre-insulated
- Superior energy performance
- Fast construction
- Air-tight construction
Advanced Spray Foams
Closed-cell applications:
