Does expanded polystyrene (EPS) present a serious fire hazard?
The EPS in an Fox Blocks has a flame retardant that allows the forms to be flame resistant. The EPS will melt when exposed to sustained temperatures over 300°F (149°C). The ignition point of the melted styrene is 600°F (315°C) (wood is approximately 500°F (260°C). Fox Blocks have been tested to meet the building code requirements for flame spread and smoke development, plus Fox Blocks may be used as fire resistant rated wall assemblies in schools and hospitals.

ICC 500 Missile Impact Testing Requirements for Storm Shelters and Safe Rooms
Fox Blocks announces that their ICF wall assembly passed the ICC 500 required Missile Impact test used to determine compliance of storm shelter and safe room design and construction from flying debris in severe high-wind weather events.
Does EPS ‘off gas’?
EPS does not off-gas. Fox Blocks forms do not and never have contained any CFC or HCFC products. The forms are made by a steam process that utilizes ‘pentene gas’ as a blowing agent. The blowing agent dissipates from the product within 48 hours of manufacturing. Fox Blocks forms are odorless, do not deteriorate, and do not off gas.

Building Commercial Retail Developments with ICF Construction
Building commercial retail developments with ICF construction creates structures that are disaster-resistant, energy-efficient, environmentally-friendly, quiet, and durable.
Can you vibrate or consolidate the concrete in ICFs?
Yes, consolidation of the concrete is one of the key elements in the placement of concrete in an ICF wall. Fox Blocks recommends internal vibration with a pencil vibrator, quickly in and slowly out.
How do frame in openings?
Fox Blocks has developed the Fox Buck specifically to frame openings such as windows and doors. The Fox Buck provides insulation around the opening plus support for the attachment of the window or door.

Let’s Talk About Our Foundation
Fox Blocks has been making insulated concrete forms since 2005. Our parent company, Airlite Plastics, was founded in 1946, and today, it is still a family owned business. Airlite produces plastic containers and insulated packaging products for a variety of industries, so we share knowledge of plastics innovation throughout the company.

Integrated Design in Architecture and Construction
In the field of architecture and construction, integrated design is a powerful solution that tackles the inefficiencies of traditional isolated processes. This approach combines different project elements under a unified vision, and proves particularly effective with Insulated Concrete Forms (ICF) like those from Fox Blocks. By using ICF, the building process becomes more efficient and collaborative.
