Open up your home

Few design elements are as impactful—or as elegant—when it comes to transforming a home as a well-considered expanse of glazing. Whether extending a period property or building a sleek new home from the ground up, slimline sliding doors can offer a seamless transition between inside and out, blurring boundaries and maximising natural light.

As the demand for open-plan living and better connectivity with the outdoors continues to rise, more homeowners are turning to innovative glazing solutions that do more than just let the sunshine in. 

One such solution is the ultra-slim sliding door systems expertly crafted by Grabex Windows, a Grand Designs Magazine Approved Premium Partner and Reynaers at Home Premier Partner.

Letting the outside in

Modern homes are designed to flow. Floor-to-ceiling glazed walls help create that fluid connection between living areas and gardens or patio areas, allowing spaces to feel larger, lighter, and more inviting. Grabex Windows specialises in bespoke sliding door systems that are engineered to maximise glass and minimise frame, bringing panoramic views and daylight to the forefront of your home’s design.

Their ultra-slim aluminium systems, including HiVision and HiFinity systems, are all about visual impact with technical performance. With slim sightlines as narrow as 20mm, these doors offer uninterrupted views, even when closed.

Design meets performance

Of course, great glazing isn’t just about good looks. Grabex’s sliding doors are built to perform, with high-spec insulation and thermally broken aluminium profiles; even those slim-framed sliding doors are precision-engineered to keep the elements at bay.

Those systems offer a wide range of high insulation upgrades and options for even better thermal and acoustic performance, making them suitable for low-energy homes and meeting low U-value requirements or Passive House design standards.

HiFinity Sliding Doors, with its floor-to-ceiling and wall-to-wall fully concealed profiles, is a prime example of the state-of-the-art structurally glazed system, which set new benchmark of excellence in modern construction, especially having been awarded Minergie certification, a Swiss construction standard with a focus on the energy efficiency, quality and maximum preservation of value.

Grabex sliding door systems also offer a broad range of options that can be tailored to the specific requirements of each and every project, amongst them:

• Double or triple glazing;
• Flush thresholds for seamless floor levels;
• A variety of RAL colours and finishes, including anodised, textured, and even woodgrain with dual colour available;
• Multi-track systems for wider openings; and
• Open Corner or Hidden Pocket Door solutions.

Whether you’re after a three-panel sliding wall for a garden-facing kitchen or a corner configuration that disappears entirely, Grabex makes it possible.

Creating the illusion of space

For homes with modest footprints or darker internal layouts, slimline doors can work design magic. By drawing the eye outward and maximising daylight, they make interiors feel more spacious—even without increasing square footage. This makes them a smart investment not just for aesthetics but for well-being too.

With increased natural light, spaces feel brighter, airier, and more comfortable. This connection to the outdoors can also have a transformative effect on mood and mental health—an often-overlooked benefit of well-designed glazing.

A Grand Design essential

It’s no surprise that sliding doors have become a signature feature in many of the homes showcased on Grand Designs. They speak to a modern lifestyle—where living spaces are flexible, light-filled, and connected to the landscape around them.

With a commitment to design, performance, and precision, Grabex Windows is helping more homeowners achieve that vision with confidence.

If you’re dreaming of a home that feels open, expansive, and effortlessly elegant, it might be time to think differently about your doors—and slide into something more spectacular.
