Specification Guidance for Material Packages
How a coordinated-package specification is structured — finish schedules, shop drawings, BOQs and sample approvals — and how to review one before anything is ordered.
This section explains the specification layer of a material package: the documents that define what you are actually buying, the order they are produced in, and the checkpoints where you approve or reject. It also explains why we confirm performance values per project rather than publishing generic figures — and why that is in your interest as a buyer.
Structure
What a Package Specification Contains
A coordinated package is only as good as the documents behind it. These are the ones that matter, in the order they usually appear.
Finish schedule
The single reference for every visible surface — finish type, color reference, sheen and application — so envelope, joinery and furniture arrive consistent instead of approximately matching.
Shop drawings
Dimensioned, project-specific drawings for windows, cabinetry and joinery, issued for your approval before production. What you approve is what gets built.
BOQ structure
The bill of quantities organized by system and location, with specifications per line — the document against which substitutions and scope changes are tracked.
Sample approvals
Physical samples of finishes and materials, approved and referenced before mass production, so color and material decisions are anchored to a real object.
Packaging & delivery spec
How each system is packed, marked and consolidated for export — including protection for finished surfaces and handling requirements at site.
Inspection hold points
The agreed stages where inspection happens and evidence is produced — in-process checks, pre-shipment inspection and the documents that accompany each.
Our Position
Why Performance Values Are Confirmed Per Project
You will not find generic performance tables on this site. That is deliberate — and this is why.
Performance belongs to a configuration
A window’s thermal and structural performance depends on the frame system, the glass build, the opening size and the glazing configuration. A single number published in a brochure cannot be true for every window in a project — let alone every project. We confirm values against your drawings during specification.
Certifications belong to a region
Design-pressure ratings, wind-load classes, egress rules and safety-glass requirements differ by market and code edition. The correct answer to “is it compliant?” is a question back: for which region and which project? Any supplier answering otherwise is guessing on your behalf.
Process
Specification in the Buying Process
Where each document appears, and what to do at each checkpoint.
01 · Drawings first
Specification starts with your drawings — plans, elevations and openings. Suppliers quoting before seeing them are quoting a guess. What drawings are required ›
02 · BOQ review
The supplier’s first deliverable is a structured BOQ against your drawings — the moment scope gaps and duplications surface. How we run BOQ review ›
03 · Shop drawings & samples
Production starts only after shop drawings and finish samples are approved. Approving drawings you have not read is how projects go wrong. What the FAQ says about samples ›
04 · Inspection & evidence
Inspection at agreed hold points, with reports and photos — the specification’s enforcement mechanism, not a courtesy. How to verify a supplier’s QC ›
