Glass combinations for different situations. 1) Street-facing homes (high noise): laminated insulating glass (e.g. 5 mm laminated + 12A + 5 mm insulated). The PVB interlayer effectively absorbs low-frequency noise (traffic), and the insulating layer blocks high-frequency noise (horns) while improving thermal performance; suited to roads, viaducts and busy areas. 2) Low floors (theft and damp resistance): double insulating glass (5 mm + 12A + 5 mm) + Low-E coating — basic insulation at lower cost; Low-E reflects UV and reduces indoor glare and heat. If security is poor, upgrade to laminated insulating glass, which stays bonded after breakage. 3) High floors (wind resistance, safety): triple-glazed insulating glass (5+12A+5+12A+5) or laminated insulating glass — multiple air layers greatly improve insulation and wind-load strength; laminated glass prevents shards flying after breakage. Add warm-edge spacers to cut edge conduction. In summary: street-facing prioritises sound insulation, low floors prioritise practicality and economy, high floors prioritise safety and wind resistance, with coating technology optimising performance.
