The Infinity Rooflights supplied by Conservatory Warmer Roof Ltd help increase the flow of natural light into indoor spaces, whilst being low maintenance with excellent thermal installation and light transmission. The glass that we use in Futures Rooflights is an energy efficient glass which is designed to prevent heat escaping out through your rooflight to the cold outdoors. All our glass rooflights have a decorated black border as standard (other Ral colours are available on request). All Glass Rooflights are high quality and are manufactured with a choice of either Double Glazed Glass which has a U-Value of 1.2w/m2 or Triple Glazed Toughened Safety Glass which has a U-Value of 0.7w/m2. They are also available in a choice of clear or blue tinted glass.
