Innovation
We know it is important for you to have confidence in your subcontractors. In today's design-build marketplace we have built our reputation on reliability, confidence and on being first in our fields for workmanship. Our support staff can provide help from the conceptual-to design-to build, we will work with the architects, engineers and contractors in building the most advanced roofing system in the construction field today.
Overview
Lightweight insulating concrete roof systems offer the unique opportunity to remove water from the roof. The ability to design custom slope to drain conditions and then have the plan followed in the roof construction sets these systems apart from rigid insulation systems. However to take advantage of this opportunity requires a large number of designs that are very difficult to create by hand drawing methods.
Example of EPS Layout
Design Parameters for the Roof Slope Layout.
A proprietary computer program has been developed that allows the following roof top conditions to vary to produce the optimum design. The program considers the following variables for each design.
- Type of substrate ( re-roof, structural concrete, metal deck)
- Type of insulating concrete ( aggregate or cellular)
- Minimum thickness of concrete above polystyrene
- R-value (minimum or average)
- Thickness of slurry coat
- Distance between polystyrene steps
- Maximum height of polystyrene step
- Pre-defined design slope
- Slope limited by wall height
- Combination of pre-defined slope and wall height limitations in same drainage area
- One drain or multiple drains in same drainage area
- Height of drains above substrate surface
- Distance drain is located from high or low point of drainage area
- Cricket design to move water between multiple drains
Once an ICRDS (Insulated Concrete Roof Deck System) is installed, building owners will never have to replace their roof insulation again and building occupants will enjoy the comforts of the construction industry's most progressive roof underlayment system
Installation
ICRDS can be installed over non-slotted or slotted galvanized corrugated metal decks, structural concrete substrates and, where appropriate, over existing roofs in recover applications. It is not intended for use in extremely hot, dry climates. ICRDS excellent fire resistance properties make it cost effective versus the more expensive alternative of adding a fireproof coating to the deck's underside, as required by most systems incorporating conventional rigid insulation board. The lightweight concrete is placed at a minimum 2-inch thickness over the top of the EPS (expanded polystyrene foam).
