HP Flush Window System

The Whitehill HP flush window is a modern high-performance successor to the Stormproof window with a flush frame, twin seals, espagnolette locking system (espag) & friction hinges. This style of window is extremely versatile and can be used in buildings of almost any architectural style. We have launched a new add-on for this window tooling to manufacture Triple-Glazed Windows, which is designed to improve sound-proofing. Our window system has been PART Q PAS24 tested and approved. We have created compliance reports and ‘setting up’ guides that must be followed to ensure manufactured windows are PART Q compliant.
