Q1
What grade is the aluminium?
Most quotes don’t say. Lower-grade extrusions are 1.0–1.2 mm wall — fine for short windows, not for a 3-metre sliding door. We default to 1.6 mm and write it on the quote line.
Aluminium, Glass & Skylight
Light, ventilation and security — the trade that decides whether a room feels closed-in or generous. We fabricate locally and install in-house.

Profiles you can actually feel the difference on
We work with the heavier 1.6 mm and 2.0 mm wall-thickness aluminium profiles for sliding and casement, not the thin contractor-grade stuff that flexes when you close it. For tempered glass we specify 8 mm or 10 mm depending on opening size and back it up with the original tempering certificate.
Skylight installations are weatherproofed three ways — internal silicone bead, external rubber gasket, and a hidden flashing detail under the roof tile. We test with a 30-minute hose flood after install before we sign off.

Two questions to ask
What homeowners forget to clarify
Q2
Is the glass actually tempered?
Tempered glass carries a tiny etched mark in one corner. We photograph the mark on each pane during install. If a pane arrives without it, it goes back the same day.
Replacing windows or adding a skylight?
Tell us roughly which side the room faces. We’ll factor heat gain into the glass spec we recommend.
