Prime all faces, including the back and ends, before installation to slow moisture uptake and reduce the risk of cupping or splitting after fixing. Store the lengths flat and supported at regular intervals to prevent bowing while on site.\u003c\/p\u003e\n\u003ch2\u003eFAQ\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eIs this cill profile suitable for listed buildings and conservation area properties?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. The machined Hardwood profile replicates the traditional weathered cill shape found on original sash windows, making it appropriate for listed buildings and conservation area work where like-for-like repair is a common planning requirement. Always confirm the specific profile with your local conservation officer if in doubt.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I order a custom length or a different timber species for my sash window cill?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNottage Timber Merchants can supply custom lengths and alternative species such  Accoya on request.

Bare machined Hardwood should be treated with a suitable exterior primer or preservative on all faces before installation. Pay particular attention to end grain, which absorbs moisture most readily. A full paint system will give the longest service life on an external cill exposed to the South Wales climate.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eFor other machined joinery profiles to complete your window project, browse the \u003ca href=\"\/collections\/pine-mouldings\"\u003epine mouldings collection\u003c\/a\u003e at Nottage Timber Merchants.
