Our process
How an order runs, drawing to doorstep.
Four steps — and once it's placed, you can see which one yours is at without picking up the phone.
Enquire
Send us sizes, a drawing or a whole schedule. You get a price and a lead time we can actually hold.
Specify
Glass make-up, spacer, gas fill and any lead or sandblast work — agreed and confirmed in writing before we cut.
Manufacture
Made in Hatfield on our BS EN 1279 line, with QC checks and batch traceability on every unit.
Deliver
On our own vehicles, on the agreed day — with a two-hour window and your driver's number in the portal.
