The Importance of Biothermic Doors

Biothermic doors, meaning they are gas-tight, are considered essential in various building projects. This is particularly true for clients who operate in manufacturing, freight, mining, research or the defence industries.

What Are Biothermic Doors?

Biothermic doors are designed to prevent gas flow between rooms or compartments by creating an airtight (gas-tight) seal. These specialised doors are built to withstand large amounts of pressure and are made to resist both thermal and chemical damage.

Why Are Biothermic Doors Important?

In many operations and industries, the presence or use of certain gases can be harmful to both employees and members of the general public. These gases can also contaminate supplies and equipment, so containing them where necessary is vital.

In these instances, biothermic doors can play a significant role in creating a safer space and keeping operations safe and hazard-free. Biothermic doors can:

  • Prevent dangerous gases from impacting unprotected people or areas
  • Prevent the spread of fire and smoke and assist in containment
  • Safeguard sensitive or sterile workspaces
  • Prevent machinery from becoming cross-contaminated

Who Utilises Biothermic or Gas Tight Doors?

Gas-tight doors have become extremely popular across a wide range of industries for their ability to provide safer and more controllable environments. Biothermic doors are commonly installed in:

  • Trains and freight carriages
  • Marine and submarine vessels
  • Oil, gas, mining and offshore facilities
  • Energy and civil engineering plants
  • Medical, pharmaceutical and scientific laboratories
  • Processing plants
  • Waste management and treatment facilities
  • Hospitals
  • Military buildings
  • Storage facilities
  • Atomic/nuclear power plants

How Do Gas Tight Doors Work?

  • Seals – Gas-tight doors use an inflatable seal to create a barrier impenetrable to gas. A built-in control panel allows the seal to be inflated or deflated with the push of a button.
  • Locks – Magnetic locks are often used to improve further the effectiveness of the airtight seal on the door, and in many cases, locks are used in conjunction with automatic door closing systems
  • Monitoring – Viewing windows are often integrated into biothermic doors to enable visual monitoring. Many door models also offer technologically advanced systems that provide real-time updates on the other side of the door’s conditions.

Biothermic Door Materials

All biothermic doors are designed with maximum durability in mind. The doors and frames are generally made from iron or steel, and the seals are commonly made using silicon, along with a high tech ‘fluoro rubber’ known as FKM or Viton.

Important Door Factors to Consider

If biothermic or gas-tight doors are required for your design or upgrade project, you must ensure that your chosen doors:

  • Are certified and comply with BCA regulations (ASxxx) regarding their airtight properties, and any other performance requirements (such as fire protection, acoustic insulation etc.)
  • Can operate as desired; i.e. do you require a hatch door, sliding door or a double-action swinging door?
  • Have been designed to meet your specific needs; note that gas-tight doors vary considerably in terms of their ability to deal with a range of temperatures, gases and chemicals, so you’ll need to select the doors that will provide you with the required level of protection.

You’ll also need to consider how difficult or easy the door installation will be, depending on the location and accessibility of your building or vessel.
