Annealed laminated glass is specified for interior and non-impact-critical glazing where fragment retention, acoustic benefit and cost matter:
Q1: What is annealed laminated glass?
It is two or more annealed (float) glass plies bonded by a PVB interlayer. “Annealed” means the glass has been slowly cooled to remove internal stress, so it is flat, stable and economical — but it is not heat-treated or tempered.
Q2: Is annealed laminated glass safe?
The PVB interlayer holds glass fragments in place on impact, so broken pieces do not fall as dangerous shards. However, annealed glass has lower mechanical strength than tempered glass. It is suitable for interior and non-impact-critical glazing; for exterior, balustrade or overhead applications we recommend tempered or heat-strengthened laminated glass.
Q3: Can it be cut or drilled?
Yes. Annealed plies can be cut, drilled, notched and edge-finished before lamination, which is one of its main advantages over tempered glass.
Q4: What is the difference between annealed and tempered laminated glass?
Tempered laminated glass uses heat-treated plies with much higher strength and impact resistance, suited to exterior and safety-critical locations. Annealed laminated glass is weaker but cheaper and easier to process, suited to interiors where fragment retention is the main requirement.
Q5: Can it be tempered after lamination?
No — once laminated, the panel cannot be tempered. Tempering must be done on the glass plies before lamination. If you need tempered performance, we supply tempered plies prior to laminating.
Q6: Does it reduce noise and UV?
Yes. The interlayer dampens sound transmission and blocks the large majority of UV radiation, protecting interiors and furnishings from fading.
Q7: What interlayer do you recommend?
For interior use, clear PVB is the standard, cost-effective choice. Colored or frosted PVB is available for decoration. SGP is recommended only where higher structural or edge stability is required.
Q8: What thicknesses and sizes are available?
Standard thickness from 3 mm to 12 mm with interlayers from 0.38 mm to 1.52 mm, producing finished panels from about 6.38 mm to 12.38 mm. Panels are cut to size to your drawings. Please send your dimensions for a quotation.
