Designed With You In Mind

The reputation of patio sliding doors has improved greatly over the years and the Liniar patio sliding door will not disappoint. So as not to detract from the beautifully slim lines of the door, it features a built-in decelerator and hidden ‘Crash Stops’. Patio door panels are heavy, due to the amount of glazing they carry, so you’ll find these clever little ex-tras a blessing – especially young or elderly users.

In addition, House of Windows patio sliding door features the patented ModLok™ system, a combined reinforcement and multi-point locking system designed in partnership with Yale, one of the world’s leading lock brands.

Designed with YOU in mind, the security system features four hook bolts, two shoot bolts at the top and bottom of each sliding pane, optional anti-snap lock cylinders and anti-lift technology, providing peace of mind that your home is protected from oppor-tunist burglars.

Not only that the locking mechanism design ensures that the four hook bolts never protrude into the room even when the door is open. This alleviates the potential danger of little ones trapping their fingers when they are ‘running in and out’.
