Mines (diamond, gold)

Thermostop offers the most secure sectional doors with the highest insulation value (up to R-32). The Sentinel mining doors feature 20ga and 16ga steel skins whereas the AluRoyal doors are equipped with 16ga aluminum skins. Both models are available in 2”, 3” and 4” thick polyurethane foam cores and are thus the best insulated doors in the industry. The Thermostop security sectional doors are widely used for police stations, detention centers, military installations and mining industry. Among many other institutional users, the Royal Canadian Mounted Police (RCMP) has chosen the Sentinel doors for its sectional doors and sally port doors requirements.
