Quality
Assurance
Quality assurance is an integral part of our manufacturing process — embedded at every stage to ensure consistency, reliability, and performance. From incoming material inspection to final dispatch, every product is monitored, tested, and verified against international standards.
All raw glass, interlayers, sealants, and accessories are checked against supplier certificates and our internal acceptance criteria before being released to production.
Tempering temperatures, autoclave pressure cycles, IGU seal integrity, and edge quality — all monitored at each stage by trained operators using calibrated instruments.
Every unit visually inspected under controlled conditions — correct viewing distance, natural light, both faces — in line with the relevant European standard before packaging.
Quality data reviewed regularly to identify trends, eliminate root causes, and refine processes — closing the loop on every issue we encounter.
Not a final check.
A continuous discipline.
Our QA framework runs from the moment raw materials arrive to the moment the finished product leaves our gate. Each process is documented, monitored, and reviewed against measurable criteria — with non-conformities flagged, investigated, and corrected before any product reaches a client.
Incoming Material
Inspection
All raw glass, interlayers, sealants, and accessories are checked against supplier certificates and our internal acceptance criteria before being released to production.
In-Process
Control
Tempering temperatures, autoclave pressure cycles, IGU seal integrity, and edge quality — all monitored at each stage by trained operators using calibrated instruments.
Final
Inspection
Every unit visually inspected under controlled conditions — correct viewing distance, natural light, both faces — in line with the relevant European standard before packaging.
Continuous
Improvement
Quality data reviewed regularly to identify trends, eliminate root causes, and refine processes — closing the loop on every issue we encounter.
From receipt to dispatch.
The controls applied at each stage of our production process — mapped to the relevant international standards.
Visual inspection, supplier certificate verification, and defect screening before any material is released to production.
Dimensional verification, edge integrity check — no chipping or micro-cracks permitted before downstream processing.
Edge quality inspected to ensure no micro-cracks before tempering, and that holes meet edge-distance requirements.
Surface cleanliness check — ensures no contaminants that could affect lamination adhesion or coating integrity.
Furnace parameters monitored continuously. Fragmentation pattern testing and heat-soak testing where required.
Interlayer bonding quality, bubble-free clarity, and optical inspection — every laminated unit verified before release.
Spacer alignment, seal integrity, and gas retention testing on every insulating glass unit produced.
Full visual inspection under controlled lighting and viewing distance per the applicable EN standard for the product type.
Protective packaging, full batch traceability, and dispatch documentation accompany every order without exception.
Built to the world's benchmarks.
Glass Premium operates in line with internationally recognized standards governing every stage of glass processing — defining the technical requirements and acceptance criteria we apply to every product.
Incoming Inspection
Raw glass quality, allowable defects (bubbles, scratches, inclusions), and coating appearance for float and coated glass before any processing begins.
Tempering
Production of safety glass through thermal treatment — covering strength increase, fragmentation pattern, heat-soak testing, and safety performance criteria.
Edging
Edge quality free from micro-cracks before tempering — defining acceptable edge defects, finishing requirements, and pre-process safety parameters.
Cutting & Drilling
Pre-heat-treatment requirements ensuring holes and shapes are made safely with proper edge distances and no crack formation before tempering.
Lamination
Safety laminated glass requirements: interlayer bonding quality, optical clarity, long-term durability, and post-breakage safety behavior.
Double Glazing
Performance of insulating glass units: gas retention, seal durability, moisture resistance, and long-term thermal efficiency in all climates.
Quality is not negotiable.
At Glass Premium, quality assurance is not a department — it is a discipline embedded in every person, every machine, and every process on our production floor. We do not ship a product we are not confident in.
Through structured controls, rigorous testing, and continuous oversight, we maintain strict adherence to technical and industrial standards — meeting both local and international expectations on every order.
Specify with confidence Every unit certified.
Every order traceable.
Our technical team provides full documentation, batch certificates, and standard compliance sheets with every order — so your project specification is fully supported.
