One envelope sub. Three core services.
Insulation, air control and protective coatings from one team, so there are fewer trades to coordinate on your job.
Spray Foam Insulation
Open-cell and closed-cell spray foam for walls, roofs, attics, rim joists and foundations, installed to match the assembly on your drawings.
- Open-cell and closed-cell
- New construction, additions, renovations
- Residential & light commercial
Air Sealing & Air Barriers
We seal the gaps, penetrations and transitions that let air move through the envelope. We also install air barriers as part of the building envelope.
- Penetrations, top plates, rim joists, rough openings
- Air barriers
- Coordinated with framing & MEP schedule
Polyurea Coatings NEW
A fast-setting, spray-applied coating that forms a seamless, flexible, waterproof membrane for terraces, decks, balconies and more.
- Seamless membrane, detailed at edges
- Texture available for slip resistance
- Surface prep reviewed before we quote
Tough, seamless protection for decks, terraces & balconies.
Polyurea is a fast-setting, spray-applied elastomeric coating. It cures into a seamless, flexible membrane that stands up to foot traffic, moisture and abrasion. We apply it where a surface needs a durable waterproof finish.
- Terraces, decks & balconies over concrete or plywood
- Detailing at edges, transitions & drip edges
- Texture can be added for slip resistance
- Substrate, prep & product reviewed with your team before we quote
- Member of the Polyurea Development Association (PDA)

Envelope questions? We can help before the walls close.
Our team has almost 20 years in the industry. GCs and architects lean on us for practical input on insulation and air barrier details, and we’re glad to talk through an assembly or a tricky transition before it’s built. Getting it right on paper costs less than fixing it in the field.
- Assembly & detail review on request
- Input on insulation type & thickness for the assembly
- Energy code planning
- REScheck compliance documentation
- Energy modeling
