Products

What we make

Six families, all fabricated in aluminium and glass, all fitted by our own installers. Every unit is made to the opening rather than bought off a shelf, so sizes are yours, not ours.

01 / SLIDING

Sliding & stacking doors

Two, three and four panel sliders, and stacking doors that push the whole run to one side so the opening is genuinely open. Fitted to patios, balconies and garden elevations.

2–4 panel
Wide spans
Charcoal · White · Wood-look

02 / FOLDING

Folding doors

Bi-folding leaves that concertina back against the reveal. The usual choice where a living room opens onto a pool or a deck and you want the full width clear.

Poolside
Full-width opening
Wood-look available

03 / WINDOWS

Windows

Top-hung, side-hung, awning, sliding and fixed lights, and combinations of those in a single frame — a fixed pane with top-hung openers over it is the most common.

Side-hung
Awning
Sliders
Fixed

04 / GLAZING

Shopfronts & fixed glazing

Large fixed elevations, corner glazing and stairwell glazing, where the job is to hold a lot of glass square and keep the sightlines thin.

Corner glazing
Stairwells
Full elevations

05 / FRAMELESS

Frameless glass & balustrades

Frameless doors and glass balustrades, specified from the heavier end of the range because there is no frame carrying the load — the glass is the structure.

Balustrades
Frameless doors
10–22mm

06 / SECURITY

Trellis gates & burglar guards

Retractable trellis gates for doors and passages, and burglar guards fitted over window openings. Powder-coated to match the frames rather than fighting them.

Burglar guards
Colour-matched

Process

Replacing what's already there

Most of our work isn't a bare site — it's a house someone lives in, with a rotten timber frame or a rusted steel one that has to come out. We cut the opening, fit the new unit, seal it and clean up. Same day where the span allows.

01STEP

What comes out

Perished timber, rusted steel, glass that no longer seals. Photographed before we touch it.

Wide opening cut through a wall with wood-look aluminium folding doors set into it, protective film on the frames and angle grinders still lying on the floor

02STEP

The new unit goes in

Fabricated to the opening we measured on site, not to a plan. It is set square, packed and levelled, with the protective film still on.

Wood-look aluminium door and two fixed side panes glazed into a finished opening, protective film still taped to every frame, floor screed not yet finished

03STEP

Glazed and squared

Fixed panes and opening leaves go in once the frame is set true. The film stays on the profiles while the rest of the site finishes around it.

04STEP

Sealed and made good

Sealed, brickwork made good, film stays on until you're happy with it.

The company

About TLEEN

TLEEN Aluminium and Glass fabricates and installs aluminium windows, doors and glass across South Africa. We are a fabricator and an installation crew in the same company, which is the part that matters on site: the person who measured your opening is accountable for the unit that arrives to fill it.

The bulk of what we do is replacement work — taking out perished timber and rusted steel frames in houses that are lived in, and cutting new openings into existing brickwork where a room needs more light than it was built with. That work is unforgiving. It is measured off the actual opening rather than off a plan, set square and packed, sealed, and the brickwork made good afterwards. The protective film stays on the frames until you have looked at it and you are happy.

We also glaze new builds from the shell up, and fit trellis security gates and burglar guards colour-matched to the frames. Quotes are priced against the sizes you send us, the glass tint and thickness you choose, and the profile colour — nothing is estimated off a photograph alone.

Made to the opening. Every unit is fabricated to your measured sizes, not cut down from a stock window.

Questions

Before you send sizes

01What do you need from me to quote?

The width and height of each opening, and a photo of the existing frame if there is one. Tell us the glass tint, the thickness and the profile colour you want and we quote against those. If you're not sure, send the sizes and photos and we'll suggest a spec.

02Can you replace windows in a house we're still living in?

Yes — that is most of our work. Perished timber and rusted steel frames come out, the opening is cut and squared, the new unit is set and packed, then sealed and the brickwork made good. Same day where the span allows.

03Can you cut a new opening into existing brickwork?

Yes. Where a room needs more light or a doorway where there wasn't one, we cut the new opening into the existing brick, fit the unit and make the brickwork good afterwards.

04What glass do you offer?

Ten tints — clear, bronze, grey, dark grey, euro grey, green, dark green, blue, reflective silver and reflective bronze — in thicknesses from 3mm to 22mm. Double glazing and performance glass are available across the range. Balustrades and frameless doors are specified from the heavier end.

05What colours do the frames come in?

Six: charcoal, black, white, wood-look, silver and bronze. Trellis gates and burglar guards are colour-matched to the frames.

06Do you do security gates as well?

Yes. Retractable trellis gates for doors and passages, and burglar guards over window openings, powder-coated to match the aluminium.

07Do you work on new builds?

Yes. We glaze new builds from the shell up — windows, sliding and folding doors, fixed elevations and balustrades — as well as doing retrofit work in occupied houses.

08How do I reach you?

WhatsApp is the fastest way and it is how we prefer to work — you can send photos and sizes straight into the chat. We're also on Instagram at @tleen.aluminium.
