General
Product Information:
ROXUL® products are mineral wool fibre insulations made from
basalt rock and slag. This combination results in a non-combustible
product with a melting point of approximately 2150°F (1177°C),
which gives it excellent fire resistance properties. ROXUL mineral
wool is a water repellent yet vapour permeable material.
Description
& Common Applications:
The RHT ™60 product is a non combustible, semi-rigid mineral
wool insulation boards that is lightweight, water repellent and
designed for high temperature applications where durability and
some flexibility are required. Common application areas for the
RHT series of board insulation are storage tank insulations, drying/oven
equipment, petro-chemical and power generating equipment protection
where high temperature, fire resistance, and moisture resistance
are concerns.
