Complete your ICF building envelope with INSUL-DECK — the insulated concrete form system designed specifically for flat and low-slope roof applications. Combine the benefits of ICF walls with a matching concrete roof deck.
What is INSUL-DECK?
INSUL-DECK is a stay-in-place forming system for concrete roof decks. Like ICF walls, it consists of EPS foam panels that support reinforced concrete. The foam provides insulation while the concrete delivers strength and durability.
Applications
- Flat roof residential (modern design)
- Low-slope commercial roofs
- Rooftop terraces and green roofs
- Parking structures
- Multi-story ICF buildings
Benefits
- Complete envelope — Match your ICF walls with ICF roof
- High R-value — Continuous insulation above conditioned space
- Storm resistance — Concrete roof survives extreme weather
- Fire resistance — Non-combustible roof assembly
- Long lifespan — Decades of maintenance-free performance
- Usable space — Support rooftop decks and equipment
Installation
INSUL-DECK panels are placed on temporary shoring, reinforced with rebar, and filled with concrete — similar to ICF walls but horizontal. After curing, the shoring is removed, leaving a finished, insulated ceiling below.
