KS 430

Our Internorm KS 430 uPVC Lift-and-Slide Door are available from Thames Valley Windows throughout Berkshire, Surrey, Hampshire, and the Southeast.

The Internorm high-performance KS 430 uPVC Lift-and-Slide Door is a cutting-edge external patio door design innovation. It offers expansive, uninterrupted views and seamlessly connects your indoor living spaces and the outside.

The KS 430 upvc lift and slide door system is a luxurious glazing solution engineered for elegance and thermal efficiency. Its minimal design creates a stunning effect, allowing maximum natural light and air to enter your home.

The Internorms KS 430 upvc lift and slide system can be recessed into a wall cavity for a frameless side element.

With maximum sizes reaching 6.5m wide and 2.8m high and the ability to accommodate sash weights up to 400kg, they are perfect additions to house renovations or new extensions.

Its low threshold enables seamless barrier-free access from inside to out, making it ideal for accessibility. It also completely opens up part of your home to the outside.

Standard toughened glass panes protect against injury in the event of glass breakage, and the standard soft handle closure ensures that the handle slides back gently and quietly, improving safety and daily ease of use.

For ultimate convenience, the Comfort Drive system enables electric opening and closing at the touch of a button and improves the door’s longevity.

Our effortlessly smooth gliding and visually stunning Internorm KS 430 lift-slide door system eliminates the distinction between inside and outside to create a harmonious union. It is available in energy-efficient double or triple glazing.  The triple gasket offers superb weatherproofing against water and air tightness. It provides enhanced thermal insulation, acoustic sound reduction, security, and exceptional finishes you’d expect from an Internorm system.

Bespoke high-quality upvc frames are manufactured to be low-maintenance and durable.

The new I-tec Decor digital printing technology offers a wide range of designs for customising the inside of your uPVC lift and slide door to complement your indoor living space.

Lift and slide doors offer many benefits over traditional sliding doors or French doors; they take up less space and provide larger, high-performance glass panels with a minimal, slim profile for unparalleled contemporary aesthetics.
