An Overview of Cavity Doors

Cavity fire doors are an excellent option for buildings with large passageways that have high foot traffic, such as hospitals or warehouses. Take a look at the options available. 

Every building requires fire doors, and for most spaces, standard fire-rated door sets are a. However, some environments require more specialised configurations. For those with strict spacial requirements, cavity doors are the perfect solution.

Cavity fire doors – also known as sliding fire doors – are best suited to environments with large passageways that have high foot traffic. Differing from traditional side-hung doors, they slide into a cavity either inside a wall or an external cavity.

Choosing Cavity Fire Doors: Your Options

There are several options and possibilities when it comes to designing, manufacturing and installing your cavity door systems:

• Fire Resistance Rating: Like regular fire doors, cavity doors can be manufactured to suit your desired fire resistance requirements. This can include 1, 2, 3, or 4-hour doors. The rating you choose will depend on your specific fire wall systems and what ratings you need to remain compliant with the building code regulations of Australia.

• Door Materials: Cavity fire doors can be manufactured using a range of materials, such as steel, aluminium, metal glass fibre and timber glass fibre. E-Core® Doors are popular fire door options that can suit sliding systems well. They are made from non-laminated construction materials and are very lightweight and versatile, making them excellent sliding solutions that can still provide reliable fire protection

• Opening & Closing Systems: The BCA (C3.6) states that all sliding fire doors must be fitted with an electromagnetic device that will:

(a) Automatically close the sliding doors more than 30 seconds, but no less than 20 seconds, after the door is released
(b) Link to an emergency system and automatically deactivate if a fire, smoke or warning system/alarm is triggered

Electromagnetic devices can also be overridden using a manual button or switch. This allows occupants to keep the door open if necessary, and close it using a manual release. Read more about Magnamatic here.

• Aesthetic Options: A variety of finishes can be applied to cavity fire doors in order to match the appearance and design of your space. Many sliding doors can also be made from fire-rated glass. This is a popular option that introduces extra visibility into the building and also enhances the presence of natural light and maximises the appearance of the space.
