Lightweight Concrete Roof Decks

Insulating Concrete Roof Deck Systems by Insul-Flow Provide Performance & Value

Whether your project involves a new roof or replacing a damaged one, lightweight concrete contractor, Insul-Flow, has a practical concrete roof deck system for your needs.

Lightweight concrete roof install on multi-family building

With years of experience installing concrete roof decks for all types of conditions, Insul-Flow helps you dial in the right insulating concrete for your building. We work extensively with Aerix Insulating Concrete and Siplast. Both products are rated for fire resistance, and offer superior thermal performance with compressive strength to resist damage over time.

Aerix Insulating Concrete for a Superior Roof

Aerix insulating concrete provides a superior lightweight concrete roof surface compared to rigid board insulation systems.  It can be

  • Installed over precast, cast-in place concrete, or galvanized steel decking.
  • The addition of insulation board increases R-values, and reduces dead load.
  • Placed over metal deck, it enhances the shear diaphragm providing additional resistance to shear forces resulting from wind or seismic activity.
  • It is easy to work with and can be pumped over 500 feet vertically and over 1,000 feet horizontally.

Siplast Ideal for Single-ply Roofing Systems

For built-up, single-ply roofing systems and re-roofing applications, Siplast offers:

  • Superior fire ratings and wind resistance
  • Cost-effective, slope-to-drain design
  • Non-combustible, nail-able roofing base
  • Excellent thermal performance, improved further with the use of insulation board
  • Custom formulations to achieve positive drainage

If your roof has vented or slotted galvanized steel decking, precast or poured-in-place concrete, Insul-Flow can place Siplast over these materials to create a seamless, smooth and hard surface ready for roofing. Water exposure will not cause deterioration.

For re-roofing over a sound substrate that will accept additional load, we can apply Siplast to the existing roof, avoiding the time and cost of a tear-off.
