The insect screen is part of the system, not an add-on — it opens inward, independently of the outward-opening sash.
We offer three grille solutions: internal grilles, between-the-glass grilles, and external grilles.
Operation and security are handled by a Jutong custom hardware set driven by an imported German handle, with multi-point locking around the sash perimeter.
