Modern Glass Technology by IQ Glass

Residential Fire Doors

Frameless Fire Rated Doors are suitable for use as an internal fire rated door creating an exceptionally modern, frameless appearance to traditionally cumbersome elements of design.

The frameless fire rated door from IQ Glass is a new generation of glazed fire doors for up to 60 minutes insulation and 60 minutes integrity fire protection in a frameless, neat design.

Detailing is minimal, with flush head and floor details when the doors are open. This fire rated door is pivoted at the head and base using specialist steel pivots that have the option electromagnetic hold open springs for automatic closing in the event of a fire.

Frameless Glass Design

A small back painted band around each opening door is the only profile that you will see which creates a neat external edge, hiding the edge of the intumescent seal of the fire rated glass.

The innovative and versatile fixing detail, using graphite strips connecting the door to any surrounding structure, means the door can be fixed into fire rated wall constructions without any chunky surrounding frame for a frameless fire rated door. Where installed into a run of fire rated structural glass a slim frame of fire rated steel or timber can be used.

Door sets can be designed as a single or double pivoting fire rated door in sizes up to 2.65m high. Handle choice is varied with the metal pull handles bonded to the surface of the glass for a neat connection detail.

Frameless Fire Rated Doors are the perfect solution for internal fire rated doors in contemporary design concepts where minimal detailing and frameless glass doors are required.

Glass Options

Door Configurations

The Frameless Fire Rated Door is available as a single or double door set, either set within a solid wall or within a specialist fire rated glass screen.

Single Fire Rated Doors have a maximum height of 2.5m with a maximum opening door opening of 1.1m. The door also has a maximum area of 2.75m2 to consider as well.

A double glass door opening can be 2.2m wide overall with a maximum height of 2.65m for the fire rated door. The maximum surface are of glass within the opening is 5.83m2 which must also be considered during specification.

Glass Specification

These frameless fire rated doors are made with specialist fire rated glass which allows both the single and double glass door to achieve a fire rating of 30/30 or 60/60 as required.

Fire Rated Glass is made with multiple layers of toughened glass layered with fire rated intumescent seals that react under the heat of a fire to create a fire resistant barrier.

The thickness of the fire rated glass is between 20-27mm for a single door and 20-28mm in a double door configuration.



These frameless glass doors have a pivoting action controlled by a floor spring box. This pivot box can be specified with an electromagnetic hold open or a non-hold open action.

The handles are structurally bonded to the face of the glass for a clean fixing detail that doesn’t alter the fire rating of the glass doors. There are 3 basic handle designs but if you would prefer a bespoke solution it may be possible.

Door Design Options

As well as a clear, frameless glass door design you can also opt for a slightly more decorative finish to the doors.

This system has now been tested to include a decorative ceramic frit to the face of the fire rated glass. The design of this pattern can be used to create the appearance of glazing bars to the glass installation offering a much more minimal appearance than an actual steel framed fire rated door would offer.

Fixed glazing with this design is available in fire screens up to EI30, any opening doors with a glazing bar design can be up to EI60. Due to the application of this ceramic fritted pattern the maximum width for any glass panel is 1.35m.


Frameless Glass Fire Doors


The clean, non-framed design of these fire rated doors is unparalleled by any other glass fire door on the market. Most other fire rated systems require large frames of steel, hardwood timber or specialist aluminium compounds to create the required fire protection.

Our Frameless Fire Rated Door can protect those essential exit ways with a minimal all glass finish. The Electromagnetic hold open floor spring can be integrated with electrical locking and fob access for restricted access through the doors if required.

Both our floor spring options have been tested to EN 1154 for controlled door closing devices and the electromagnetic option is tested to EN 1155 as well.

The doors are fitted with electromagnetic hold open floor springs that are activated when the fire alarm sounds to create a fire rated barrier of 60/60 to the hallway exit routes.
