Instead of replacing the entire case (the box in the wall), we can manufacture new timber sashes containing\u00a0<strong>heritage slimline double glazed units t<\/strong>hat fit into your original frames.

Unlike the simple \u201cfitch fasteners\u201d of the past, new versions come with\u00a0<strong>keyed locks, sash restrictors<\/strong>\u00a0(which allow the window to open slightly for ventilation but not enough for someone to enter), and even smart sensors.<\/p>\n<h3>\u00a0<\/h3>\n<h3 class=\"schema-faq-section\"><strong class=\"schema-faq-question\">How can I tell if my windows need repair or a full replacement?<\/strong><\/h3>\n<p class=\"schema-faq-answer\"><strong>The Penknife Test:<\/strong>\u00a0If you suspect rot in the sill, try to push a penknife into the wood. If it sinks in easily, there is significant rot.<br \/>Most sash windows in Scotland can be\u00a0<strong>refurbished<\/strong>\u00a0even if they look bad.

Traditional single-glazed windows are a major source of heat loss. Upgrading to double-glazed timber sashes with\u00a0<strong>modern draught-proofing<\/strong>\u00a0(brushes and seals) can reduce heat loss through the window by up to\u00a0<strong>70%<\/strong>.
