Noise Reduction

Along with the many advantages of aluminium windows, Alteza also delivers exceptional sound insulating capabilities of up to 30 decibels by simply causing the sound wave to lose power. This is achieved by using materials that absorb and reflect all noise – like glazing, using double sealants, and by building frames with thicker walls.
