Innovation can take many forms. For Liniar, this means launching new, cutting-edge products and continually improving its existing product range to be more efficient in terms of security, safety or energy efficiency.

The latest new development has now been launched and relates to Liniar’s ModLok™ Patio Door system – providing fabricators with the ability to manufacture the system to the exacting standards of the PAS24 Security accreditation. This is excellent news for fabricators and installers supplying to the new build market, who need to install a product that achieves the required security accreditations but is also ergonomic, stylish and environmentally friendly.

As part of achieving the PAS24 accreditation, the updated Liniar ModLok™ patio door is fully tested to BS 6375 (parts 1, 2 and 3) for weather performance.

Strong and secure

Liniar’s ModLok™ patio door system has always been highly secure, featuring four bi-directional lock clusters incorporating eight mushroom head locking points housed within its existing aluminium box section, which provides additional rigidity and strength. By adding a 3-star rated ‘anti-snap’ cylinder, the new lock extensions, and the PAS24 kit to internally sliding doors, a Part Q Building Regulation product can be achieved. 

All these new parts are retro-fit, thus making for an easy fabrication process – no additional routing preps are required to achieve PAS24 and Part Q compliance.

The Liniar Difference

The ModLok™ patio door from Liniar does more than look the part. It boasts a sturdy eight-wheel acetal roller for an effortless ‘light as air’ gliding motion. This revolutionary roller also allows for superb load-bearing capacity of up to 120kg per sash, giving peace of mind with the additional weight associated with IGUs for PAS24 whilst maintaining the options for maximum size doors where required.

Built-in deceleration means homeowners won’t see any unsightly crash stops, and ergonomic handles are simple to operate.

Designed with installers in mind, the Liniar ModLok™ patio door offers a low threshold option with no trench excavation required. Additionally, the outer frame can be mechanically jointed for easier access to those installations in tighter spaces.

For homeowners, the ModLok™ patio door is an ideal choice. Available in a wide range of colours and finishes, it offers ultra-personalisation and exceptional usability for a variety of property styles.
