Where your sash windows are beyond economical repair or it is not possible to install replacement sashes JTP Sash windows can manufacture complete replacement windows including the box frames and sills.

All of our replacement windows are manufactured here in our Newton Abbot workshop by highly skilled craftsmen using traditional carpentry techniques in line with guidelines set out by historic England and English heritage for the manufacture and preservation of traditional box sash windows.

As all of our sash windows are manufactured bespoke we are able to match any specific moulding profile or design to match each individual specification.

Timber Specification

Our sash windows can be manufactured from a range of soft and hardwoods to suit all requirements and budgets.

Glazing Specification

Our sash windows can be glazed using a wide variety of glass from 4mm single glazed to 24mm double glazed units, from obscure glass to acoustic glass and even stained glass.

The most popular glazing specification for sash windows is an 14mm slim line double glazed unit which utilises the latest warm edge spacer bar technology, Planithurm total plus glass (Outer pane) with the units being filled with Argon gas for optimum performance.

Perimeter Draught Seal System

All of our replacement sash windows come as standard with our unique perimeter draught seal system. This system is very discreet and can reduce heat loss by up to 90% whilst also reducing noise and ensuring your windows glide effortlessly within the box frame.

Window finishing

All of our windows come as standard with 2 coats of primer sealer using the industrys leading “Teknos paint system” although we do offer a fully finished service as required. We are able to match any Farrow and Ball, Dulux or standard RAL colour.
