Showrooms and natural light

managing large glazing

Current trends in architecture are focusing on curtain walls and oversize windows to maximise natural light. For interior designers, however, these windows cause significant thermal stress on horizontal surfaces. Direct solar heat filtering through the glazing generates spikes in temperature that can cause flexible vinyl flooring to swell, compromising the flatness of the underfloor base.

The role of the high-density rigid core

GXG SPC is engineered to minimise these changes. As the composite is rigid, the flooring acts as a stabiliser, so while a conventional vinyl product can be affected by temperature fluctuations, GXG’s stone core maintains its dimensional stability to a far greater degree. This means high-precision installation is possible even in buildings subject to high thermal stresses and those with large windows.

Protection and colour stability

Not only is technical durability vital, the aesthetic has to stay on trend too. Prolonged exposure to UV rays is the main cause of fading for synthetic flooring. To prevent this wear, each GXG tile is treated with a certified UV coating (EN ISO 105-B02 Level 6). This coating acts as a screen for the pigments, ensuring the colour tone stays even over time and limiting differences between areas in the shade and those exposed to direct sunlight.
