Reflective glass is either clear or tinted and features a thin metallic or metal oxide layer on its surface. This layer is applied during the float glass manufacturing process. Generally, the thicker the glass, the less light it allows through. Reflective coatings are designed to minimize heat transfer and glare while still permitting visible light to pass through. These windows are particularly suitable for south-facing homes and apartments, which often experience significant heat during summer months. Reflective windows help prevent air space overheating and reduce electricity consumption from continuous air conditioner use.
