Welcome to the official site of Comais srl.
Comais is the most important European manufacturer of low density calcium silicate for thermal insulation at high temperatures, for fire protection and for humidity control in residential buildings. Comais quality has a long tradition of over thirty years and it's recognized internationally by the most prestigious clients.
Comais is part of the Etex Group, world leader in products for the building industry, with branches worldwide with 70 companies and over 12.000 employees.
All Comais products, all verified through the quality processes ISO 9001 e ISO 14.000, have been created based on the different uses, particularly for fire protection and high temperature insulation. Moreover the powder of calcium silicate from Comais has several uses in the fields of cements, paints and machanical industries.
During these last years Isopiù®, the Comais system for insulation and humidity control in residential buildings, is earning more and more success.
PROMASIL® plates
Insulating plates and cut-out plates for high temperature based on tobormorite or xolonite, thermally treated and completely free from amiantus and RCF fibers.
PROMASIL®, produced in a modern plant with a patented production process, assures the best solution today in the field of industrial thermal insulation at high temperatures thanks to its thermophysical characteristics, technical-economic ratio, as well as the total lack of ceramic fibers and other materials regarded as detrimental to the health and the environment.
The modern, patented production process guarantees the high quality of PROMASIL® in compliance with the ASTM e DIN regulations.
ISOPIU'® Panel
the Isopiù® panel in calcium silicate makes it possible to build thermal insulation with an inner covering and it totally eliminates thermal bridges with remarkable energy savings.
Isopiù® removes condensation of humidity and prevents mould formation, healing humid rooms.
Isopiù® represents the best possible solution to space issues: it does not need a retaining wall and it can be painted directly.
Isopiù®, thanks to its porous structure, can adjust the level of humidity.
The Comais calcium silicate is certified as incombustible 'zero class' and represents a barrier to fires.
PROMAXON® Addictive
PROMAXON® is an additive, well known for its typical spherical form.
PROMAXON® is a white mineral powder. The open pourous inner structure is very typical.
PROMAXON® D has a special form, its open pourous inner structure is additionally enveloped by an outer shell of close knitted crystals.
PROMAXON® is a calcium silicate hydrate and its chemical formula Ca6Si6017 (0H)2 corresponds with the mineral Xonotlite.
PROMAXON® has a pH value of 9-10 for its typical spherical form.
PROMAXON® has depending on the type from a mean partical diameter from 12 resp. 35 to 85 µm.
