Frequently Asked Questions
Aluminum Sliding Windows FAQ
Thermal break aluminum windows utilize a reinforced polyamide (PA66) insulating strip that separates interior and exterior aluminum frames. This barrier drastically reduces heat transfer, prevents interior condensation, and lowers building energy consumption while maintaining structural integrity.
Yes. Veltor Window & Door Co., Ltd. manufactures every unit to exact project window schedules. We offer RAL custom color matching, anodized finishes, wood-grain transfers, and fluorocarbon (PVDF) spray coatings for high-salinity coastal environments.
We supply double or triple IGUs (Insulated Glass Units) with Low-E coatings, argon gas filling, warm-edge spacers, and PVB laminated acoustic glass to achieve U-values down to 1.2 W/m²K and STC ratings up to 42 dB.
Our sliding window systems feature concealed high-capacity drainage channels, step-down sill tracks, and continuous weather-stripping seals that effectively prevent water backflow under high wind pressures.
