Engineered for precision
01 — Project Management System
Measured, tracked, delivered.
A single point of contact from measurement to handover.
Site measurement & sign-off
Every opening is measured and confirmed with the client before an order is placed with the factory, eliminating the guesswork that causes on-site rework.
Engineering coordination
Wind-load, weather exposure, and structural inputs are calculated for the specific site and shared with the client ahead of fabrication.
Stage-by-stage visibility
Fabrication, dispatch, and installation milestones are tracked against a shared timeline, so you're updated at every stage — not just at the end.
One point of contact
A single Selective Systems coordinator owns your project end to end, rather than passing you between departments.

02 — End-to-End Service
From concept to completion.
From concept to final delivery, without gaps.
Consultation & site survey
We assess your openings, structure, and requirements before recommending a system — not after.
Factory-engineered manufacturing
Your order is fabricated to spec at TOSTEM's facility, where controlled conditions keep tested and actual performance identical.
Logistics & site readiness
Units are packed and dispatched as complete, labelled window-in-a-box units, minimising handling risk before they reach your site.
Installation & handover
Our own installation teams complete the fit, seal, and finish, and walk you through the finished work before signing off.

03 — Customer Satisfaction
Built around you.
Built on tailored solutions and long-term support.
Tailored to the site
Recommendations are based on your building's actual wind, weather, and noise exposure — not a one-size-fits-all product line.
Transparent testing
TOSTEM tests full-size samples for water tightness, air tightness, and sound insulation, and welcomes clients to see the process.
Responsive after-sales support
Questions or adjustments after installation are handled by the same team that installed your project, not a separate helpdesk.
Built for the long term
TEXGUARD-coated finishes and EPDM gaskets are engineered to hold their colour, seal, and function for decades, not just through the warranty period.

05 — On-Time Delivery
On time, every time.
Strict timelines, optimised logistics.
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.
