Usually 25mm externally and the remainder of the lining, in this case 75mm, is recessed atthe head and each jamb.  \nThe recessed reveal is the best window detail and why the Sash windows have endured.  \nInternal Glazing Bead  \nSash Lift  \nWindow Board groove  \nCill  \n5  \n4 Lomax + Wood Ltd 2018  \nTypical Details-Box Sash Window ina Flush Reveal  \nNot as common asthe recessed reveal, it is simply not as good performance wise oraeasthetically.  \nSTR.WIDTH  \nFRAME WIDTH  \n5  \nTopSash Meeting Rail  \nBottomSash Meeting Rail  \nExternal Jamb Liner  \nExternal Head Liner  \nDouble Glazed LowE Unit  \nExternal plant on Architrave detail  \n5  \n5 FRAME HEIGHT  \n100  \nSTR.

The golden ratio has been used as early as 430 BC and is still being used today in modern architecture.  \nThe Greeks referred to the golden ratio as Phi. While the more widely known “pi”is the ratio of the circumference of acircle to its diameter,“phi”is the ratio of line segments that occur when aline is divided ina specific way. Unlike “pi”, which is a transcendental number,“phi”is the solution toa quadratic equation. It createsan ideal rectangle. Phi orthe Golden Ratio consists of two quantities (1 and 1.168). The ratio between the sum of those two quantities and the larger oneof themis the same asthe ratio between the larger one and the smaller. In architectural terms this takes the form of the Golden Rectangle, where the ratio of the shorter side to the longer is 1:1.618.  \nIn windows this would meanthatifan opening was tobe 1000mm wide the opening height would need tobe 1618mm.  \n8 Lomax + Wood Ltd 2018  \nThe Golden Ratio in Windows  \nThe Wood family, through Dennis Wood who worked in partnership with Derek Mumford, have designed and supplied quality timber windows and doors for over sixty years.
