Frameless glass doors in Castlereagh: what to know
A floor spring sits in a steel box set into the floor below the door, controlling closing speed and hold-open. It needs a recess cut into the screed, so it is far simpler to plan before tiles, stone or timber flooring are laid than to retrofit later.
Toughened glass cannot be cut, drilled or notched once it has been toughened. Holes for patch fittings, cut-outs for locks and handles, and any shaped corners are all made before toughening, which is why we template the opening first and the glass is made to order rather than cut on site.
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
- Castlereagh is about 5 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 Castlereagh the midwinter sun reaches about 12° above the horizon at noon, with roughly 7.0 hours of daylight, rising to about 59° and 17.0 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.

Frameless Glass in Castlereagh: questions
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.
How long does it take to get a frameless glass door fitted?
Once the opening is templated, the glass is made to order and toughened, which usually takes a few weeks. Fitting a single door or screen is normally done in a day, while larger entrances or runs of screens take longer. Your written quote sets out the expected programme, and we confirm the date when the glass is ready.
Will a frameless glass door block noise and draughts?
Only partly. Frameless doors run with small gaps at the sides and bottom so the glass can swing freely, which lets some sound and air through. Clear seal strips can narrow the gaps. If you need a quiet meeting room or a draught-free external entrance, a framed or acoustic glazed system will perform better, and we can quote for both.
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.
