Profile: Coastal Windows is a provider of windows, doors, and conservatories. We are accredited with ISO 9001 certification. We have many styles of standard casement windows. It is also possible to opt for tilt and turn designs that give two ways of opening the windows. We offer products with weather resistant properties. The PVC-u profile used is chosen for its toughness, durability, and long term effects of both sun and rain. Strength and security go hand in hand with galvanized steel reinforcement. Our conservatories are built with PVC-u frames that are reinforced with galvanized steel, to ensure that the conservatory has strength and rigidity. Our vertical sliding windows are supplied with PVC-u frames. Security is enhanced through the combination of internal glazing and the claw interlock between the two sliding sections. The window provides an easy sliding action by use of correctly tensioned balances.
