But in listed buildings or most conservation areas, planning consent will be refused for uPVC.<\/p>\n<\/details>\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>How long do timber sash windows last?<\/summary>\n<p>Engineered hardwood or accoya: 60+ years with standard maintenance (repainting every 5-7 years). Softwood: 15-25 years. Original Victorian pine sashes in good condition can last another 50 years with restoration \u2014 that&#8217;s why restoration often beats replacement.<\/p>\n<\/details>\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>What&#8217;s slimline double glazing?<\/summary>\n<p>Sealed glass units 14-20mm thick (vs standard 28mm) designed to fit within heritage sash profiles that can&#8217;t accommodate a thicker unit. Thermal performance is slightly lower than standard double glazing but much better than original single-glazed sashes. Typical u-value 1.6-1.9 vs 1.2-1.4 for standard.<\/p>\n<\/details>\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Do new sashes add value to a period property?<\/summary>\n<p>Yes, significantly. Rightmove 2025 HomeReport data shows period homes with restored or heritage-grade new sash windows commanding 3-5% higher sale prices than comparable homes with damaged or replaced-with-uPVC sashes. In a \u00a3600k Victorian terrace that&#8217;s \u00a318,000-\u00a330,000 of resale value \u2014 often more than the cost of the work.<\/p>\n<\/details>\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Can any FENSA installer fit sash windows?<\/summary>\n<p>Technically yes, but sash work is skilled work. Not every FENSA-registered installer handles it competently \u2014 especially restoration and heritage-grade.
