What we supply
Glass
- 10 mm and 12 mm toughened
- The usual glass for frameless doors and side panels.
- 12.8 mm toughened laminated
- Where the glass must stay in place if it breaks.
Processing and the build-up
- Toughening
- Every door and side panel is toughened to BS EN 12150-1.
- Patch and lock cut-outs
- Cut to the fitting maker's template before toughening. Holes follow the BS EN 12150-1 limits for toughened glass: at least as wide as the glass is thick, and clear of edges and corners by a multiple of the thickness. Our drawing checks every position before cutting.
- Manifestation
- Marking at the two safety levels, drawn on the design.
- Made to measure
- Toughened glass cannot be cut, drilled, notched or edge-worked after it is toughened. Every size, hole and cut-out is fixed on the drawing before the glass is made.
Regulations
Approved Document K, section 5 (requirement K4)
Glazing in a critical location must break safely (BS EN 12600 class 3 or better), be robust, be in small panes, or be protected. Critical locations: any glass in a door or within 300 mm of a door edge up to 1500 mm above the floor, and any glass in a wall up to 800 mm above the floor. A pane wider than 900 mm in a door or door side panel needs class 2.
England. This section took over the former Approved Document N.
Approved Document K, section 7 (requirement K5.2)
Large areas of glass that people could walk into, such as glass doors and screens, carry marking at two levels: 850 to 1000 mm and 1400 to 1600 mm above the floor.
Buildings other than homes, and glazed doors and screens where they could be mistaken for an opening.
Approved Document M (access to and use of buildings)
Doors in buildings other than homes need a minimum clear opening width, an opening force a wheelchair user can manage, and glass that is easy to see. The door is drawn to these on the quotation drawing.
Entrance doors and doors in partitions in buildings other than homes.
Installation
- The floor spring box is set level in the screed before the floor finish, at the position on our drawing.
- The head fixing needs a solid structure above the door to take the top pivot.
- Adjust the door's closing speed and check it closes without slamming.
Care and cleaning
- Clean with warm water and a little washing-up liquid or a household glass cleaner, using a soft cloth, a chamois or a squeegee, then dry with a lint-free cloth.
- Never use scouring pads, wire wool, razor blades, scrapers or powder cleaners: they scratch the surface for good.
- Wipe stainless steel fittings with fresh water and dry them. Near the sea or a pool, do it every few weeks to stop brown tea staining.
- Have floor springs serviced as the maker recommends.
