Polycarbonate sheets have become one of the most popular roofing and glazing materials for residential, commercial, industrial, and agricultural projects across Kenya. Their excellent impact resistance, lightweight construction, and superior light transmission make them an ideal alternative to traditional glass and ordinary plastic roofing sheets.
However, one of the most common questions asked by homeowners, contractors, architects, and farmers is: How long do UV coated polycarbonate sheets last in the Kenyan sun?
Kenya experiences intense solar radiation throughout much of the year, especially in regions such as Nairobi, Mombasa, Malindi, Garissa, Isiolo, Turkana, and other arid or coastal areas. Without adequate UV protection, ordinary plastic sheets gradually become brittle, lose clarity, and eventually crack after prolonged exposure to sunlight.
Modern UV coated polycarbonate sheets are specifically engineered to withstand these harsh conditions. High-quality UV-protected panels can maintain their strength, transparency, and structural integrity for well over a decade when correctly installed and properly maintained.
Ali Glaziers supplies premium polycarbonate sheets, glass products, architectural hardware, flooring solutions, roofing materials, and construction products for residential, commercial, and agricultural projects throughout Kenya.
