Privacy Ensured: High rise condominiums and office blocks are often built too close for privacy. At times, fabric curtains are not sufficient to block out prying eyes and ears. Roll down all your SlimLine Shutters for more privacy. Noise Control: Up to 50% reduction of noise from your windows. With SlimLine Window Shutters you block noise from traffic, aircraft, barking dogs and noisy neibours. Low maintenance: SlimLine Window Shutters are easy to install. All the box covers, side guides, brackets and bottom bar are power coated. Side Guides are inserted with PVC strips for low noise operation. No need to grease for a smooth operation.
