By using the Optima profile, we can offer new windows that meet the highest standards of security. Our windows and doors are fitted with a high-security multi-point locking system and is internally glazed, preventing a burglar from removing the pane from the outside. The uPVC profile itself is durable and strong, standing tall against uninvited visitors. The Central Eurogroove within the profile gives the sash greater rigidity. Our Window Locking System is Secured by Design as standard with dog bolts to the hinge side of the window and appropriate glass where applicable.
