How to fit glass balustrade panels on a staircase

Inspired by the Richard Burbidge Elements system guide. This walk-through is based on Richard Burbidge's detailed fitting video "How To Fit Elements® Inset Glass". Richard Burbidge is a British staircase manufacturer with decades of experience, and their Elements Inset Glass system has been independently tested to UK Building Regulations. The video is thorough and worth watching from start to finish before you begin any work.

1. Check the existing staircase and measure up

Glass balustrade panel systems are designed to fit specific pitch angles — typically between 40° and 43° for standard UK staircases. Measure your pitch carefully before ordering. The newel posts also need to be in sound condition: if they are wobbly or rotten at the base, sort that first.

Measure the total run of the staircase and the height needed for the balustrading. Glass panels come in set widths and heights, so your measurements will dictate what combination of panels you need. Most suppliers have a measurement guide — use it, and do not guess.

2. Remove the existing spindles

Spindles on most UK staircases are glued into the base and top rail, with some nailed as well. Work them free with a sharp chisel and a mallet, being careful not to damage the handrail or the string. Take your time — rushing this stage damages the woodwork that you are keeping.

Once the spindles are out, remove the bottom rail if you are replacing it with the new system's channel. Fill any holes in the string or tread with a flexible wood filler and sand flush when dry.

3. Cut and fit the base channel

The glass panels sit in a U-shaped aluminium or composite channel that is fixed to the stair treads or string. Cut the channel to length using a fine-tooth saw or angle grinder with a metal cutting disc, mitreing the ends at the correct pitch angle.

Fix the channel down securely with the fixings provided. It needs to be straight and at the correct height — too high and the panels will not reach the handrail; too low and you get an unsightly gap at the top. A dry run with a panel in place before fixing anything permanently is time well spent.

4. Insert the glass panels

The panels are made from toughened safety glass — they are heavy, and they need careful handling. Work with a helper. Slot each panel into the base channel, then tilt it upright and check it sits vertical. Most systems use rubber gaskets or foam tape inside the channel to grip and cushion the glass.

Do not force a panel that does not want to go in — check the channel alignment first. Glass that is wedged at an angle will look awful and may be under stress.

5. Fit the top rail or handrail

With all panels in place, offer up the handrail. On most systems this clips or screws to the newel post at each end and is supported by brackets at intervals along the run. Check it is level and at the correct height — UK Building Regulations specify a minimum handrail height of 900mm from the pitch line of the stair.

Fix the rail to the newels securely and add any intermediate brackets. The glass panels should now be held firmly between the base channel and the underside of the rail. Wiggle each panel gently to confirm it is not loose.

6. Fit newel caps and finishing pieces

Most systems include decorative caps for the top of the newel posts, cover plates for the base channel fixings, and end caps for the handrail. Press or screw these into place to cover any raw edges and fixings. It is the finishing pieces that make a glass balustrade look properly done rather than half-finished.

Check every panel one more time, then wipe the glass down with a glass cleaner and a lint-free cloth. The first clean always reveals a few smudges and finger marks from installation.

7. Check and sign off the work

Apply a firm sideways push to each panel to confirm it is held securely. The system should feel completely solid — glass balustrades must meet the load requirements in UK Building Regulations (Part K), and a panel that moves is not compliant.

If in any doubt about the structural integrity or compliance of the installation, have it checked by a competent person before using the staircase regularly.

When to call a handyman

Call Richard if you want the job done properly first time. Staircase work involves Building Regulations compliance, and getting the measurements or the installation wrong with toughened glass is a costly mistake. A professional fitting also tends to produce a much cleaner finish.
