Construction schedules rarely allow slack for a delayed window delivery, which is why TOSTEM's manufacturing model is built around compressing the unpredictable part of the process — on-site work — down to its minimum. By manufacturing the entire window at the factory and leaving only assembly for site, installation timelines become dramatically more predictable.
Because units are dispatched as complete, labelled window-in-a-box packages, there is minimal risk of damage or breakage in transit — and minimal risk of a shipment showing up incomplete or mismatched to the opening it was built for. That reliability is what lets us commit to installation dates and hold them.
On our side, we plan logistics and installation crews against your project's actual construction schedule, not a generic queue — so your windows and doors arrive when your site is actually ready for them.
What this looks like on site.

Delivered as complete units, ready for a fast, clean install.

Installation planned against your actual site schedule.

Fewer on-site surprises, from delivery through to handover.
How we deliver it.
Compressed site timelines
With most of the work done at the factory, on-site assembly time is minimised, keeping installation dates predictable.
Damage-minimised transit
Labelled window-in-a-box packaging keeps each unit protected and matched to its opening from factory to site.
Logistics matched to your schedule
Dispatch and installation crews are planned against your actual construction timeline, not a generic delivery queue.
Fewer surprises on-site
Manufacturing accuracy prevents the mismatches and last-minute delays that come from on-site fabrication.
