Liniar 80mm Resurgence Flush Sash Window
The UK’s first double-rebated uPVC flush sash window. Resurgence takes Liniar’s timber-alternative concept to a new level — no visible external gasket, genuinely foiled on both faces, and engineered for the very best in weatherproofing and energy efficiency.
Why choose this window
The next generation of flush sash
Resurgence takes everything that makes a flush sash window a genuine timber alternative, then removes the one visible giveaway every other uPVC flush window still has.
UK’s first double-rebated seal
No visible external gasket between frame and sash — just a clean, unbroken sightline and genuinely superior weatherproofing versus a standard flush window.
Thermally efficient
A+ energy ratings and U-values as low as 0.84 W/(m²K), backed by Liniar’s patented bubble gasket for genuinely draught-free performance.
Foiled on both faces
Resurgence is foiled on the interior as well as the exterior, so the timber-look finish stays authentic even with the window open.
Secure, guaranteed
PAS24 and Secured by Design accredited, compliant with Part Q, and backed by a 10-year frame guarantee.
