Manufacturer's Product Description

Trial 90 is an innovative SPI product from the mixed aluminium-wood family. The system is enriched by solid wood interiors, improved by a special 90° joint on the sash and frame which improves both the aesthetic and functional qualities of the product. Its special design with flat, square profiles is reminiscent of the classic wood window, with the added advantage of external aluminium.
Trial 90 is an aluminium-polyamide-wood open-joint system which guarantees high insulation performance and a more simple installation process.
The Trial 90 windows have cellular EPDM bi-component gaskets which are highly insulating and crushproof.
