Profile: Rainbow Double Glazing Ltd. is a provider of windows, doors and conservatories. We also enhance with installation services. Our product list includes conservatories, windows, doors, porches and roofline products. We avail a range of windows. Our tilt & turn window has added benefits like; with the turn of a handle the sash can be opened to the tilt position for ventilation, or wider still for ease of cleaning. In case of roofline products, we provide Timbrex. It has the textured look of timber without the pain of painting or the potential for rot. It is produced by hot pressing real wood fibers from a renewable source into the shape and texture of a rough sawn plank, and the baking on a colored finish.
