The WarmCore door is available in residential, french and bi-fold door options and a choice of four external cladding styles – Pencil Round, Chamfered, Square and Decorative. At the heart of WarmCore products is a thermal core which significantly out-performs the polyamide thermal breaks commonly used in aluminium systems. “The door can achieve a u-value of just 1.0 W/m2K, compared to 1.8 W/m2K on an aluminium door,” Zac explains. The size of the door is another key benefit. Folding sliding doors can measure up to six metres wide, meaning they can be partnered with wide-span conservatory and orangery roofs, which Astraseal will colour code in either white, cream, black or grey to match.
The door is packed with innovative features such as double-strength sash corners and custom-engineered extruded aluminium hinges for additional security; clip-fit hinges for easy on-site installation and a triple sealed weatherstrip to eliminate draughts and ensure optimum weather tightness. Warm Core joins Astraseal’s already comprehensive product range that includes the full range of windows and doors available from Rehau, Smarts and Reynaers; composite doors set in a Rehau outerframe and Synseal Global conservatory roofs. Astraseal produces all IGUs in-house and can colour-coat frames in any RAL colour. “Warm Core is the perfect ‘half way house’ between our PVC-U and aluminium product range and I welcome any companies that wish to speak to me and learn more about this innovative system,” Zac concluded.
