As the construction industry continues pursuing long‑term energy efficiency and operational stability, architects and contractors are seeking solar control glass that avoids the durability risks of coated products. BTG introduces BTG68 Ice Blue Float Glass, a body‑tinted blue float glass without surface coating, delivering superior solar‑control performance versus conventional thermal‑reflective coated glass.
BTG68 Ice Blue Float Glass achieves solar‑control performance through proprietary raw‑material formulation. Unlike coated glass whose performance gradually declines over service life, its heat absorption comes from the glass substrate itself, guaranteeing permanent and non‑deteriorating thermal‑insulation performance. With visible light transmittance of 68%, the product delivers total solar energy rejection of 67%, effectively cutting solar heat gain and lowering air‑conditioning loads. It balances natural daylight and indoor comfort and reduces the sensation of overheating under direct sunlight. The product features five prominent strengths:
1.Permanent Substrate Thermal Insulation
Its thermal performance originates from the glass body, maintaining stable heat shielding throughout the whole service cycle without performance attenuation, realizing long‑term reliable energy‑saving effects.
2.Optimized Daylight & Heat Rejection
Visible light transmittance reaches 68%, while total solar energy rejection hits 67%. It greatly reduces indoor heat intrusion and creates a cooler indoor environment compared with clear float glass.
3.Effective UV Protection
The glass blocks 68% of ultraviolet rays.* It protects occupants' skin from UV damage and slows fading and ageing of indoor furniture, textiles and decorations.
*UV‑blocking figure is internal lab reference data, not covered in this performance table.
4.Ultra‑Low Spontaneous Breakage Risk
Proprietary melting technology restrains the generation of nickel sulphide impurities. After tempering, its spontaneous breakage rate is far below 0.03%, over 90% lower than standard clear float glass, solving the industry pain point of high self‑explosion risk for tempered glass.
5.Excellent Processing Compatibility
Processing requirements are consistent with ordinary clear float glass. No equipment renovation is needed for cutting, edge grinding and tempering. Uniform heating during tempering ensures even stress distribution, better flatness and lower energy consumption during thermal processing.
Stock thicknesses include 4mm and 6mm, with standard jumbo sizes available to support custom cutting for curtain walls, residential windows, sunrooms and commercial facades.
To clearly demonstrate its competitive strength, we provide a horizontal performance comparison of 6mm glass products:
Glass configuration is subject to project requirements.
Sustainable building designs prioritize materials that integrate performance, safety and full‑lifecycle value. BTG68 Ice Blue Float Glass eliminates hidden risks of coating failure while exceeding the solar control performance of grey reflective coated glass. It serves as a cost‑effective, low‑maintenance option for new construction and renovation projects developing energy‑efficient building envelopes.
In summary, BTG68 Ice Blue Float Glass sets a new benchmark for body‑tinted solar control glass. It combines permanent substrate thermal insulation, balanced daylight and heat shielding, UV protection, enhanced safety and convenient deep processing. It acts as a reliable, high‑performance alternative to coated reflective glass for modern architectural projects.
