ABAKUS goGRAIN Windows in Białystok — Bio-Hybrid with Spelt

goGRAIN — What Window Is It and What Are Its Specs?

goGRAIN is a bio-hybrid uPVC window in which 10% of the profile material is natural spelt husk — and that is what sets it apart from classic uPVC. It is built on the Salamander bluEvolution 82 platform with an 82 mm build depth, 6-chamber frame and sash profiles, and reaches a whole-window value of Uw = 0,76 W/m²K.

Warmth comes from a triple-glazed, twin-chamber unit at Ug = 0,5 W/m²K and an arrangement of three gaskets: two colour-matched abutment gaskets and one central one, welded at the corners. It is a window for those who want to combine good insulation with a lower environmental impact.

Why Does 10% Spelt Husk Make a Difference?

Adding 10% natural spelt husk is not marketing but a real change in the profile's properties. Replacing part of the plastic with a plant-based raw material cuts the CO₂ emissions generated during profile production by up to 20%.

• CO₂ emissions cut by up to 20% — a lower carbon footprint for the window already at the profile production stage.
• Linear expansion lower by 30% — the profile "works" less under temperature changes, which favours the window's durability and geometry.
• Shrinkage lower by 15% — greater dimensional stability of the profile over time.
• A unique bio-hybrid surface — a natural texture that classic, smooth uPVC cannot give.

The profile is further strengthened by stiffening ribs and a 2 mm steel reinforcement, and we join the corners using the seamless Cutmaster technology. If you are comparing lines for eco-credentials, set goGRAIN against the rest of the uPVC windows in our range.

Security and Hardware — How Does goGRAIN Protect?

goGRAIN combines eco-design with security at RC2 class. Burglary resistance is handled by Roto NX perimeter hardware and a Roto Line Secustik anti-burglary handle or lumiNO handles.

• RC2 class — makes it harder to lever the window open with simple tools, a sensible standard for ground floors and easily reachable windows.
• Roto NX hardware — a durable, smoothly operating tilt-and-turn mechanism.
• Roto Line Secustik handle — blocks the handle from being turned from outside; alternatively, the elegant lumiNO handles.
• 2 mm steel reinforcement — a rigid base for the hardware and the whole structure.

It is a good solution for detached houses in Podlasie, where both warmth and a sense of security matter. During the survey we will pick the handle and the scope of security to suit your windows.

Fitting in Białystok, Warranty and Instalments

Even a bio-hybrid window at Uw 0,76 will not deliver its full benefits with a poor fit — skipped insulation where it meets the wall spoils the result despite good specs. That is why we fit goGRAIN with our own Pro-Plast crew, with a warm, airtight fit and a careful finish; we weld the profiles using Abakus IRMC Production technology.

We start with a free on-site survey and a free written quote, we provide transport, and the purchase can be spread over instalments. As a local Białystok firm we give a 5-year warranty and aftercare. Book a free survey and find out the goGRAIN window price for your home.
