I didn't know that the regs required fire resistance if windows are close to the boundary but apparently they do having just looked it up in Part B of the Building Regs. You are allowed a certain amount of "unprotected area"(windows or doors) that rises as the distance from the boundary increases. If you exceed this area the exterior doors or windows have to be fire rated. As heat develops within the source area, pressure within the enclosed room begins to build relative to the pressure outside. Once the fire reaches equilibrium in the positive pressure zone, smoke, hot gases and flames are forced through any openings in the door or window assembly.

Toughened glass is the most common type of glass used in partitioning. This glass is taken through a heating process to toughen it, making it four to five times stronger and more durable than annealed glass. When a toughened glass panel is broken, it should break into small bits rather than large sharp shards.
Damage sustained to a portion of the building
Glass with this designation has been tested to meet impact safety requirements required for areas such as doors, sidelights, and areas close to the floor. Costs will largely depend on the size and specification of the glass walls. You also need to consider installation costs (not just the materials). The type of doors and ironmongery you decide to use can significantly impact glass partition costs.

Ratings are assigned in levels from 1 to 8, with a Level 8 rating being the highest (able to stop a 7.62mm rifle lead core full metal copper jacket, military ball). The Designer Series doors and frames incorporate precise European engineering, providing a sleek, modern alternative to traditional hollow metal frames. Both surfaces are ground and polished to provide superior surface quality, improving the overall clarity. FireLite Premium is the industry leader for quality and is unmatched by alternative products or production methods. From our headquarters in Burnley we supply both to the trade and public where we pride ourselves in offering high quality glass at competitive prices.
- At AFC, we are always striving to bring you the best products and the most advanced fire protection solutions that complement modern building designs.
- Glass doors and glazing tracks can be purchased in various styles and colours.
- I had an extension done 10yrs ago and seem to remember the architect saying something about maximum window size of 1 sq mtr.
They are still required to satisfy AD M wherever they are intended to offer freedom of movement around the building. This is particularly important for fire rated glass doors on heavy circulation routes within compartment walls, or partitions providing compartmentation. The two types of fire rated glass are fire-protective and fire-resistive.
They will most likely give you their honest opinion and can tell you from first hand experience. Densglass Gold Boards can be drilled and nailed using conventional hand tools, offering many of the properties of timber. Widely recognised by the GOLD colour, DensGlass fibreglass mat gypsum sheathing board, has an exemplary track record that spans more than 30 years in the US market place and now available in the UK exclusively from Benx.
We specialise in fire glass for commercial uses such as glass doors and internal glass partitions. Our glass experts 30 min fire rated glass can produce cut to size fire glass to the latest British safety standards, with options including 30 and 60-minute fire rated glass in 7mm thickness. Ray-Bar reserves the right to refuse service or sales to anyone at any time.No direct sales to the general public.
Deciding on the types of door you need depends on what you want to achieve with your glass partitioning project and your budget. For example, if privacy and noise reduction is essential to you, you may want to consider double glazed doors with acoustic reduction. However, if you're going to reduce costs, single glazed doors (or door leaves) may be the best option for you. As there are vast options available for facade solutions, with this in mind, costs can vary dramatically. If you are using very large glass units, specialist electrical glass finishes or many layers of glass the cost of the glass package will increase.
This type of glass can offer fire protection for up to 180 minutes and complies with Integrity and Insulation (EI) criteria and Integrity and Low Radiation (EW) criteria. The glass is guaranteed to remain in its frame and protect from fire for a minimum stated time. Fire rated glass prevents the spread of flames and smoke in a building up to a certified period of time to comply with British Fire Test Standards.
Yes, it is possible to incorporate fire rated glass doors into large areas of fire resistant glazing. However, their primary function is to act as a fire barrier when required to do so. That means that they must be capable of being closed, without manual intervention, when there is a fire. Recent tragic events have brought the use of fire resistant construction products sharply into focus. It is not just a case of replacing an area of solid wall construction with fire resistant glass. A solid wall will typically span between structural floors, providing a complete fire barrier.
LPS1270 differs from EN 356 in that the test is carried out by a person able to vary his choice of tools and method of attack, within the duration of the test. LPCB believe this better represents an actual attack rather than the robotic method used in EN356. The result is to provide a range of tested categories, dependent on the tools allowed and the duration of the test, the higher categories’ of which exceed those of EN356. The GPX Builders Series also offers 60 – 90 Minute Temperature Rise Doors. These are minute full-vision, temperature rise doors with SuperLite II-XL, and SuperLite II-XL IGU clear fire resistive glazing.
Another cost-effective solution for double-glazed windows is frameless secondary double glazing, where an 8mm glass pane is added inside existing frames. Ensure your architect or project manager is up to speed on all building costs and incorporates those regulations into your project’s design. Failing to follow codes is expensive -- chances are a building inspector will cite your project and require you to replace the glass. Fire resistive glass provides the same defense against flames and smoke as fire-protective glazing, but adds further protection by blocking the transfer of radiant and conductive heat.
