As one of the most trusted installers and applicators of lightweight insulating concrete (LWIC) roof decks in the Southeast, Bonitz of Georgia has decades of experience helping building owners save money throughout the life span of their structure with durable, high-performing roof decks.
Why Choose LWIC Roof Decks?
What makes LWIC roof decks the ideal choice for large commercial or institutional buildings? Here are just a few advantages of LWIC roof decks over traditional tapered insulation systems.
- Stable insulation value: Unlike polyiso boards, which lose a percentage of their R-value every year, LWIC roof decks maintain a stable R-value across the life span of the roof.
- Reroofing efficiency: LWIC roof decks do not need to be torn off during reroofing, saving roofing contractors significant time, money, and environmental impact. Only the roofing membrane needs to be removed and replaced.
- Membrane longevity: Raising the temperature of a roof membrane can significantly decrease its life span. The excellent thermal insulation properties of LWIC roof decks reduce temperature fluctuation on the membrane, leading to greater longevity.
- Lower environmental impact: LWIC roof decks reduce waste generated during reroofing (less debris that needs to be disposed of in a landfill). Additionally, their thermal insulation properties reduce energy consumption of the building.
- High compressive strength: LWIC roof decks can achieve high psi. LWIC is a durable substrate for a roofing membrane and acts as a stable and supportive base.
- Positive slope: With traditional tapered insulation systems, multiple layers of board are required to achieve a positive slope. To create slope in LWIC roof decks, we simply cut the EPS holey boards to the appropriate thickness to ensure effective drainage.
- Fire rating: LWIC is a non-combustible material, making it inherently fire-resistant. LWIC roof deck systems can achieve high hourly fire ratings and do not require additional fireproofing on the underside of the metal deck.
- High wind uplift resistance: LWIC roof decks are a good choice for coastal or high-rise buildings, because the lightweight insulating concrete bonds extremely well to approved substrates as well as galvanized metal deck in new construction. This bond offers excellent wind uplift resistance.
- Composite action: LWIC roof deck systems can use a lighter gauge metal deck, because the metal deck and LWIC layer work together to create a stronger roofing system.
- Acoustical performance: We have numerous tested assemblies resulting in very high STC values due to the high density of LWIC. Several of the assemblies were tested in combination with an acoustical substrate (such as Tectum) and those assemblies delivered high STC & NRC values.

Pre-Spec Services for Roof Decks
Our team of experts works with architects, engineers, and roofing consultants to specify their roof deck system before the project begins. We value engineer your project to meet your building’s needs while maximizing your budget. Our design assistance includes:
- Product/system selection for new construction or re-roof
- Field analysis of existing roofs, roof decks, and limited structures
- Loading/diaphragm/uplift
- Roof/slope plan
- R-value calculation
- Acoustical analysis
- Guide specifications
- Budget pricing
- Field product demos
Bonitz of Georgia Is a Leading Installer of Metal Roof Decks With LWIC
Lightweight insulating concrete (LWIC) is often combined with galvanized steel deck to create a composite roof deck system yielding superior vertical loading, diaphragm, and wind uplift. We have decades of experience not only assisting in the design of these systems but actual hands-on knowledge of how the systems come together in the field. These combination systems range from standard metal roof deck to form deck and even to metal acoustical roof deck systems.
