How does fire-resistant glass work?

Fire-resistant glass must be installed as part of a tested and approved glazing system, installed by specialists, in order for it to work properly. To protect individuals against the heat and danger of a fire inside a home or commercial property, fire-resistant glass is manufactured from several layers of toughened glass, which is often interspersed by intumescent layers. These layers are noteworthy for their ability to withstand high temperatures without breaking or deforming.

In the event of a fire, the outermost layers of the fire-resistant glass will break, allowing the intumescent materials to expand and form a thick, opaque barrier that blocks the passage of flames, heat, or smoke.

When purchasing fire-resistant glass from Osborn Glass, we will send our experts to your home or commercial premises to ensure that the product is properly installed and will provide protection against hazards.

What is fire-resistant glass used for?

Fire-resistant glass can be used indoors or outdoors, as long as it is installed by a specialist and in line with manufacturer specifications. Unlike the more traditional forms of wired fire-rated glass – which we also supply – our fire-rated laminated glass has the general appearance of plain glass, but is thicker. This adds an aesthetic benefit and means that it can be used for a variety of purposes.

For example, in a commercial setting, fire-resistant glass can be used in skylights to provide interior light while maximising fire safety. It is also commonly used for doors and windows, as well as partition walls where a particular area of the building may require fire containment protection.

How much does fire-resistant glass cost?

Every glass product, fitting, survey, and supply is different, which means that they all have distinct associated costs. We quote every job individually and there is no rule-of-thumb. Enquire with us to get a quote for your residential or commercial space.

How will my fire-resistant glass be delivered?

Before we give you a quote for the job, we will ask if the job is supply and fit or supply only. Additional contractors on site will also be billed. This will all be included in an upfront invoice, so you’ll have full transparency of costs every step of the way.
