Profile Features

Low Threshold Height

The KS 430 is manufactured with a naturally lowered threshold. A lowered threshold results in the bottom section of the framework being slimmer in design. This improves ease of access and reduces the chance of injury - a hugely appealing feature for end users.

Visual Comfort

A naturally slim uPVC-aluminium profile allows wide spanning glazed units to be fitted into the KS 430 lift-slide door. These allows natural light to flow into a house or apartment, brightening either up and making them more spacious and improving visual comfort for the end user.

Comfort Drive

Comfort drive software is available with the KS 430. This electric motor allows for effortless operation for any end user or homeowner. It also improves the longevity of the door, preventing bounce back that may come with drive-less lift-side alternatives.

Triple Gaskets

Every Internorm profile is designed with triple gaskets as standard. The end user will benefit from total weatherproofing. A phenomenal standard of water and air-tightness can be expected for decades after the commercial project has been completed.


These lift-sliding doors can be manufactured with turn handles that come with or without a recessed or tilting option. The handles we install are always secure and easy to operate, without compromising on aesthetics.
