High (with wood-grain finishes). Modern/Industrial appearance. Toughness 60+ years (if kept). 25-- 30 years. 40+ years. Upkeep Regular painting/staining. Low; simple cleaning. Low. Thermal Efficiency Outstanding natural insulation. High (multi-chambered profiles). High (with thermal breaks). Sustainability Sustainable and biodegradable. Recyclable but artificial. Highly recyclable. For numerous, Accoya wood is the gold standard for customized sash windows. It is a chemically customized softwood that offers stability and toughness going beyond that of the majority of hardwoods, ensuring the sashes do not warp or swell-- a common problem with older wood windows.
The Importance of Custom Glazing Modern customized sash windows regularly make use of "Slimline" double glazing. This technology enables for a vacuum or gas-filled space in between 2 thin sheets of glass, providing the thermal benefits of modern-day windows while preserving the thin profile of original single-glazed panes.
