OFFSET EXTERIOR APPEARANCE

Window frames, sashes and glass are offset. The familiar view relies on our modern technology and adds depth to the architecture of your home.

Offset appearance inside

Window frames and sashes are also offset on the inside, contributing to a cosy living environment.

More daylight

Larger glass surfaces and narrower frames mean more daylight in the home, higher solar energy gain and a larger proportion of the surface area covered by highly heat-insulating triple glazing.

IDEAL FOR RENOVATION

With its slimmer frames, Zirkon has an advantage over older plastic windows from previous decades that are in need of renovation. This has a particularly positive effect on small windows.

Stylish accessories

Beautiful and stylish handles complete the charming New Classic look – many are also available in matching designs for house and interior doors.

Design freedom: Rungs

Stylish glazing bars for a classic look or without glazing bars for modern clarity. This means that Zirkon suits many interior styles.

Simple and charming

Zirkon does away with glass strips on the inside and features a staggered, classic-looking exterior. With its simple lines, Zirkon exudes quality and charm.

Sustainable plastic

With up to 80% recycled plastic in Zirkon, we are committed to sustainability without compromising on quality and design. The surface is bright white and made of fresh plastic.

EASY CARE

Effortless cleaning, as the profile contour and fittings are designed to be simple and easy to clean.

Elegant wood or aluminium look

You can achieve a beautiful, matt look with the new ‘natural oak’ and ‘black’ finishes. They are also very durable and scratch-resistant.

Sleek design
More sunshine in your home

Zirkon stands out thanks to its particularly slim frames, which are 15%* slimmer than comparable offset plastic/aluminium windows on the market.

Your advantages

+ More daylight and brighter living spaces

+ More solar energy gain – saving heating costs in winter

+ Greater well-being for you and your family

IT'S ALL ABOUT THE DETAILS

a11y.jump_slider_end

SPRINGS

Whether warm and classic or minimalist and modern: Zirkon gives you freedom. With glazing bars, you can add accents steeped in history, while without glazing bars, you can create a calm, contemporary look.

NEARLY BARRIER-FREE

Floor-to-ceiling windows and patio doors are exposed to harsh weather conditions. The virtually barrier-free Isostep threshold keeps even large amounts of water out. Thanks to good thermal insulation, the interior remains particularly comfortable.

 

concealed hinges as standard

Simple thanks to concealed hinges, convertible with glazing bars or fixed pane combinations – Zirkon is flexible and contemporary for style-conscious living.

skylights

Skylights are an elegant solution for bringing even more daylight into your home – especially where high ceilings are required. They extend the window upwards and create a stylish overall look with continuous lines.

Simple design

No glazing beads on the inside and a fine, elegant frame appearance on the outside – for clean lines and timeless aesthetics. The slim frame appearance is retained even in combination with fixed parts.

Suitable for extreme weather conditions

Heavy rainfall, strong storms and cold weather are no match for our leak-proof ratings, which can withstand hurricane-force winds.
