Understanding fire-rated steel-look windows and doors

It’s important to know that aluminium has no fire rating. Some also assume that simply glazing a product with fire-resistant glass is enough. This is both dangerous and not fit for purpose where a fire protection requirement exists.

Even more important is the make-up, manufacture, materials and installation needed for a screen or doorway. Every component and fitting come together providing the correct fire protection and a product that must do its job should a fire break out.

There are also several reasons why fire-rated steel-look windows and doors are specified. Reasons include providing escape routes from the home or preventing the spread of fire into neighbouring rooms and inside the home generally. It’s also important on three-storey properties. These are just some of many crucial reasons for Building Regulations and why they’re relevant in construction and renovation work.

Therefore, if there’s a requirement for fire protection in the home with glazing, seek the services of a professional supplier and installer. The products available are certified, come with the correct components, seals and glass. These products must be either steel or steel-clad aluminium. There are also fire-rated aluminium doors, windows and screens using specific fire insulation components inserted or mounted in the internal chambers of the aluminium profiles. As well as this, intumescent seals, strips and tapes are used for smoke and fire protection.

In every case, they’re certified and compliant with suitable regulations and British standards, such as BS476 Part 22 or European Standards (EN 1634:1 –2000).

Design and construction of fire-rated steel-look windows and doors

When speaking to a good installer about buying steel look windows, you rely on them for the right products and advice. With fire rated products it’s a little different.

The fire-rating requirement, its resistance to heat or preventing the progress of the fire is down to Building Regulations. Building Control stipulates the requirement. Once you have this, a specialist fire-rated steel-look doors and windows supplier provides the solution. They are not there to determine the level of protection you need. Instead, these specialist installers and products provide a suitable fire-rated product once you know what’s required.

The difference between fire-rated and non fire-rated

Crucially, don’t let basic products with fire-rated glass mislead you. These are standard door sets, aluminium or steel merely fitted with fire-rated glass. They don’t come with certification either.

A correctly designed fire-rated product is one of superb engineering and comes with a lot of work behind it designed for protection and your safety.

Aside from glass, profiles are strengthened and sometimes come with internal reinforcement profiles. As well as this much of the product comes welded not mechanically joined, like aluminium.

Then there is the work done on the hardware. In addition to specialist fire-resistant seals, tapes and brushes, handles and locks may come with extra reinforcement and steel plates. Even the glazing beads holding the glass in place use fire-resistant studs or other fixings. Aluminium beads just clip on! Expanding seals and tapes do so when heated further assisting the protection of the overall screen.

Even the fixings, sealants and accessories used are different from regular doors, usually carried out by expert installers.

You’ll also find stamps and identification throughout the product and especially on the glass panes. In many cases, this is also a Building Regulations requirement.

The difference between fire integrity and fire insulation

European and British Standards classify fire ratings. They usually fall under Fire Integrity and Fire Insulation.

Fire Integrity provides a physical barrer restricting the progress of a fire. This also includes smoke and gasses. Overall fire integrity is there preventing the building from even greater damage.

The requirement for Fire Insulation is there to limit heat transfer from one side of the glazed screen, door or partition to the other. The rationale is also the prevention of fire on the other side of the screen.

These ratings of course, help people escape from a fire and protection the building. In commercial buildings, schools, hospitals, apartment blocks etc, corridors or common areas will have fire-rated product. In many cases doors often have smoke or fire control devices as well as door closing devices.

The product you find come classified with a rating for integrity and insulation, one or both. Numbers then denote how many minutes protection the product comes certified with.

For Example:

30/0 or E30 = 30 minutes of fire integrity only.

30/30 or EI30 = 30 mixtures of fire integrity and insulation

60/0 or E60 = 60 minutes of fire integrity only.

60/60 or EI60 = 60 mixtures of fire integrity and insulation

Glass used in fire-rated steel-look windows and doors

Pyroguard, Pyrobel, Pyrobelite, Pyrodur and Pyrostop arę just some of the fire-restant glass you’ll find in certified products. Some come mainly as single glass in various thicknesses up to sealed units.

The level of protection also varies by glass type as does its suitability for the product. So it’s not unusual to find glass designed for steel, steel-based or timber products providing fire protection. A professional installer will advise on the right type for your project and to meet Building Control requirements.
