Thermal Insulating Wool types I and II are composed of fine, stable and uniformly textured inorganic glass fibers, off white to light tan color, highly resilient, bonded together by non-water soluble, fire retardant special high temperature resistant thermosetting and heat resistant resin. They are free from coarse fibers and shot due to their mineral composition. Type I is available in rolls, while type II comes in batt form only.
Afico TIW Insulation is intended for use in industrial and commercial application as thermal and acoustical insulation for boilers, vessels, precipitators, ducts, chimney liners, chimney stacks, breechings, petrochemical storage tanks, water heaters, refrigerators and freezers, ovens and cookers, washing machines, dryers and dishwasher machines and other household appliances, and types of industrial equipment operating at temperatures upto 540°C to 1000°F.
TIW Insulation is available in two types:
Type I is used in applications requiring a light weight easy to handle and install insulation such as that used in panel systems, flexible wrap, industrial ovens, or over irregular surfaces.
Type II is especially suitable for use in metal mesh blankets, it may also be used in panel systems for precipitators, ducts and breechings, where more compressive strength than that afforded by Type I is required.
This light weight makes TIW types I and II insulation easy to handle and install even when large size boards are used. There is no tendency for pinhole elongation- a frequent source of heat leaks in heavier products such as rockwool/stonewool products. The virtual absence of shot, and their consistent fibrous glass composition, enable TIW TYPES I and II insulations to withstand the effects of high temperature and vibration without slumping, crumbling, or breaking.
