Details
Synergy is our answer for anyone who wants the warmth of a wood interior with the low-maintenance exterior of aluminum, without the chunky sightlines that combination usually requires. The hidden-sash design gets the visible frame down to just 90mm for tilt-and-turn units and 88mm for fixed windows — roughly a third narrower than comparable wood-aluminum systems — so more of the opening is glass.
A standard aluminum cladding shell (removable for an all-wood look, if preferred) protects the timber core from the weather, while structural ratings up to NAFS CW=80 for tilt-and-turn units mean the slim profile isn’t just for show. NFRC-certified performance and a choice of six wood species make Synergy a strong option for modern builds that still want a genuine wood window.
