Architectural Material Taxonomy

Commercial Glass Classification Index

Every architectural glass specification must rigorously separate base float substrate, thermal/chemical treatment, polymer interlayer construction, surface coatings, and regulatory fire or barrier classifications.

BS EN 12150-1Fully Populated

Toughened Safety Glass (Tempered)

Thermal pre-stressing engineered for high impact resistance, wind-load capacity, and diced safety fracture.

Safety:Class 1C1 (BS EN 12600: drop height 1200mm)
Acoustic:Rw 29 (-2; -3) dB (4mm) to Rw 35 (-1; -2) dB (12mm) — exhibits marked coincidence dip at critical frequencies
EN CompliantView Full Specification
BS EN 14449Fully Populated

Laminated Safety & Security Glass

High-integrity polymer interlayers providing mandatory post-breakage retention, fall prevention, and acoustic damping.

Safety:Class 1B1 or 2B2 (BS EN 12600); Class P1A to P5A (BS EN 356 manual attack)
Acoustic:Rw 33 dB to Rw 42 dB (acoustic PVB achieves +3 to +5 dB reduction over monolithic glass of equivalent mass)

BS EN 1279 (Parts 1–6)Fully Populated

Insulating Glass Units (Double & Triple IGUs)

Hermetically sealed multi-pane glazing assemblies engineered for thermal transmittance control, solar shading, and condensation prevention.

Safety:Determined by individual glass plies (inner/outer toughened or laminated to BS EN 12600)
Acoustic:Rw 31 (-2; -5) dB (standard 4-16-4) up to Rw 46 (-2; -6) dB (dissimilar thicknesses + acoustic laminated pane)

BS EN 13501-2Fully Populated

Fire-Resistant Glazing Systems

Certified intumescent barrier assemblies engineered for Integrity (E), Radiation Control (EW), and Thermal Insulation (EI).

Safety:Class 1B1 or 1C1 (BS EN 12600) on approved fire-rated variants
Acoustic:Rw 38 dB to Rw 47 dB (thick multi-ply intumescent gel layers provide exceptional acoustic attenuation)
EN CompliantView Full Specification
BS EN ISO 10140-2Fully Populated

Acoustic Laminated Glazing

Viscoelastic damping interlayers designed to flatten the acoustic coincidence dip and silence commercial environments.

Safety:Class 1B1 (BS EN 12600)
Acoustic:Rw 36 (-1; -3) dB (6.8mm) up to Rw 52 (-2; -7) dB (engineered dual-laminate double glazed cavity with 100mm gap)
EN CompliantView Full Specification
BS EN 1096 (Parts 1–4)Fully Populated

Solar-Control & Selective Low-E Glazing

Magnetron-sputtered microscopic metallic nanocoatings reflecting infrared solar energy while preserving high visual transparency.

Safety:Supplied annealed or thermally toughened to suit structural wind and thermal stress
Acoustic:Rw 31 dB to Rw 42 dB dependent on configuration
EN CompliantView Full Specification
BS EN 1036-1Fully Populated

Commercial & Architectural Mirrors

Copper-free silvered reflective surfaces engineered with safety backing and high-humidity corrosion resistance.

Safety:Class 2B2 when fitted with cross-linked polypropylene woven safety backing film
Acoustic:Rw 29 dB to 31 dB
EN CompliantView Full Specification
BS EN 12150-1Fully Populated

Decorative Ceramic Frit & Spandrel Glass

Opaque ceramic enamelled panels engineered to conceal floor slabs and structural building services while harmonising facade aesthetics.
