Rubb Thermohall® buildings offer flexible insulation R-Values depending on the needs of the customer. Thermohall® R values ranges from R-11(2”) up to R-35(8”). Full HVAC/heating and dehumidification systems are adaptable to Rubb structures.


Thermohall® has minimal or no thermal bridging, thereby eliminating or greatly reducing condensation and enhancing thermal efficiency. Thermohall® provides a full vapor seal, is water repellent and absorbs neither moisture or odors.


Technical regulations and guidelines set standards for both sound and fire insulation. Our patented insulated fabric cladding system satisfies the requirements for sound passage reduction, essential for customers near roads or airports. In addition to the fabric’s unique strength, it is long lasting, and low (if any) maintenance is required throughout the life of the building.
