Caernarfon: glass internal doors
Toughened glass can very occasionally break on its own because of nickel sulphide inclusions. Heat soak testing to BS EN 14179 reduces that risk by breaking flawed panels in the factory before delivery, though it cannot remove the risk entirely. It is often specified for large doors and screens in busy buildings.
In workplaces in England, Wales and Scotland, the Workplace (Health, Safety and Welfare) Regulations 1992 require glass in doors, walls and partitions to be of safety material or protected where needed for safety, and to be marked or otherwise made apparent so people notice it.
Fixed glass screens are held in slim channels or clamps at the floor, walls and ceiling, and the head fixing needs something solid to bite into. Walls and ceilings are rarely perfectly square, so templating records the true shape and the glass is made to follow it, keeping gaps even.
Frameless glass doors are usually made from 10mm or 12mm toughened safety glass, with the thickness chosen to suit the door height and its hardware. With no frame, the glass itself carries the hinges, handles and locks, so every fitting is specified together with the glass.

- Coast
- Caernarfon is about 2 km from the coast or a tidal estuary, so salt air and wind-driven rain are worth planning for. External frameless entrances near the sea face salt spray on patch fittings, pivots and floor spring covers, which can mark or pit finishes over time. Hardware suited to exposed sites, and rinsing fittings during routine cleaning, help them stay smooth and presentable.
- Daylight and sun
- In Caernarfon the midwinter sun reaches about 13° above the horizon at noon, with roughly 7.3 hours of daylight, rising to about 60° and 16.7 hours in midsummer. Clear frameless doors and screens pass daylight deep into hallways and inner rooms. Where a screen faces low winter sun, glare and reflections can be strong, so satin bands or tinted glass can help, while low-iron glass keeps pale colours true.
- Access and setting
- Older cottages and farmhouses rarely have square openings or level floors, so templating matters even more for frameless glass. Floors may also lack the depth for a floor spring, in which case top-hung sliding gear or wall hinges can suit better.
- Rules in Wales
- In Wales, Approved Document N covers safety glazing: safety glass is needed in and around doors and in low-level glazing where people could walk into it.

For shops and other non-domestic buildings in Wales, access and glazing-visibility guidance applies to entrances and large glazed areas.
What you can choose
Fixed glass screen
A non-opening panel held in slim channels or clamps, used to divide rooms, line stairs or form a side panel beside a glass door.
Frameless sliding door
A glass panel running on top-hung sliding gear across the opening, saving floor space where a swinging door would get in the way.
Glass-to-wall hinged door
Hinges clamp the glass directly to a wall or fixed glass panel. Suits lighter internal doors where there is no room for a floor spring.
Frameless Glass in Caernarfon: questions
Can a frameless glass door be locked?
Yes. A patch lock at the bottom of the door shoots a bolt into a keep in the floor, and a centre lock can join a pair of doors. A glass door does not offer the same resistance as a solid door, so for external entrances you may also want shutters, an alarm or laminated security glass in adjoining screens.
How do I look after a frameless glass door?
Clean the glass with a soft cloth and a non-abrasive glass cleaner, and wipe metal fittings with a damp cloth rather than harsh chemicals. Do not hang anything from the door or let it slam against a stop. If the door starts closing too hard or drops out of line, the floor spring or pivots can be adjusted before wear sets in.
What thickness of glass is used for frameless glass doors?
Frameless doors usually use 10mm or 12mm toughened safety glass. The thicker glass is generally used for taller or wider doors and for busy commercial entrances, while 10mm often suits internal doors in homes. The hardware maker's limits for panel weight and size also guide the choice, and we confirm the thickness in your written quote.
Can a frameless glass door be fitted into my existing doorway?
Usually, yes. We survey the opening to check the head and walls can take the fixings, and template it so the glass follows any out-of-square edges. A floor spring needs a recess in the floor, so where that is not practical we may suggest a top pivot, wall hinges or sliding gear instead. Some making good of plaster may be needed.
