INSWOOL HP Blanket from HarbisonWalker International is a refractory ceramic fiber (RCF) blanket rated at 2,300 degrees F.

It is flexible, highly insulating, thermal shock resistant and lightweight. INSWOOL HP has high strength, in both hot and cold environments. If it becomes wet upon contact with water, steam or oil, its thermal and physical properties are restored upon drying. It is not suitable for environments with high gas velocities or particulates. It is available in a range of densities and sizes. Standard size is 1" x 24" x 25'. Also comes in 2" x 24" x 25' option. Select desired option via drop down menu. Call for more information.
OVENZZ™ LW CAST is a lightweight, insulating castable refractory with extraordinary strength and excellent insulating properties.

It is suitable for casting shapes, pouring in place and filling large cracks and holes. It can be used as an insulating backup over a dome or under the hearth in a pizza oven. OVENZZ LW CAST provides more a thermal-efficient solution than denser products. It is capable of service temperatures up to 2,500 degrees F. HWI OVENZZ products are certified by NSF International and maintain NSF/ANSI Standard 51 for use as a food equipment material and in food applications. Available in 55 lb. bags. You'll need 73 lbs. of product per cu.ft. Mix 1.6 gallons of water per bag. Orders limited to 3 bags.

KAST-O-LITE 26 LI is a low-iron insulating castable that can meet the demands of severe furnace environments.

Its high alumina content improves maximum service temperature and It's low-iron content minimizes destructive CO disintegration by reducing furnace atmospheres. This product's high strength reduces cracking from mechanical abuse or steel shell flexing. It can be used as a backup for furnace floors and roofs; in boilers, air and oil heaters; in furnace stacks and flues; and as an insulating backer over the dome or under the hearth of a pizza oven. It offers a maximum service temperature of 2,600 degrees F. Available in 55 lb bags. Mix approximately 1.3 gallons of water per 55 lb bag. About 86 lb of product is needed per cu. ft.
