Alternative solution

Rubb Thermohall® insulated warehouses offer an alternative solution to conventional buildings while providing high thermal insulation along with full relocatability. All Thermohall® buildings can be delivered to suit all customers’ insulation requirements.

Insulation and heating

The depth of insulated cladding ranges from 50mm to 200mm, which provides a range of U Values to suit your requirements. Rubb can also supply various heat sources within the structure such as oil or gas fired hot air units, radiant heating, heat pump or electric fan heaters.


Thermohall® features high density non-combustible glass wool insulation encapsulated within a heavy duty PVC fabric, which is designed and manufactured in-house to suit site-specific project requirements. All materials are of the highest quality and meet regulations.

Fire safety performance

Rubb buildings offer significant fire safety advantages over other building types, including lower risk of combustion, flashover and structural failure, even in severe fires. The fabric will not propagate flame or sustain combustion when exposed to a severe fire.

Thermohall® has excellent drainage properties, is water repellent and does not absorb moisture or odours. It helps eliminate condensation. We deliver our Thermohall® clad structures with simple or sophisticated ventilation systems to provide a comfortable working environment.


Technical regulations and guidelines set standards for sound insulation. Our patented insulated fabric cladding system satisfies the requirements for sound passage, which is essential for our customers who are located in industrial areas or near roads or airports.


The insulation consists mainly of recycled glass. Thermohall® cladding can provide many environmental benefits, including reduced energy use and helping support a stable indoor temperature all year round. Rubb structures are also fully reusable across the sectors we serve.


All materials used to create a Rubb building can be recycled if necessary. No materials from Rubb structures are considered to create any toxic or hazardous waste. Rubb's steel and PVC can be recycled through various means.

Adaptable structures

Rubb Thermohall® structures offer flexibility and full relocatability. Adapting, extending and moving these modular insulated buildings is easy and cost effective in a busy, ever changing business environment.
