Exclusive Design Features
The Heritage window features the slimmest frame section available in high performance joinery, with a 140mm frame depth and glass line to daylight frame width of 47mm.
The Heritage Cords & Weights Sliding Sash window is ideal for the most architecturally sensitive of projects with the option of single or slimline double glazing.
The double glazed siding sash provides energy efficient period living, with slimline 14mm krypton filled glazing to suit listed properties where historically traditional double glazing has been rejected.
The Heritage Cords & Weights Sliding Sash combines period aesthetics with outstanding weather ratings. The design was tested to BS6375, undertaken by independent body BM Trada and achieved exceptional results.
The Bereco Sliding Sash design achieved the highest classification achievable with a UK Exposure Category of 2000, 600pa (class 3) for Air permeability, 250pa water tightness and 0.8 air leakage.
