MODULES
Delta Modules have the highest insulating value achievable in a ceramic fiber lining. Each module is comprised of folded blanket under compression to ensure a tight seal and a “spring-back” action not found in typical wallpaper linings.
Our ceramic fiber modules are carefully inspected in multiple stages of the assembly process to ensure they meet our customers' specifications. All hardware is manufactured in-house and made in the USA.
All modules are available in grades of Low bio-persistent (LBP), 2300°F RCF, 2600°F RCF, 3000°F Polycrystalline Wool (PCW), & Hybrid Style
