Premium aluminium with thermal break + triple glazing can reach Uw 0.9. The biggest energy difference comes from the perimeter seal \u2014 sliding doors have more linear seal than a casement, so quality of install matters more.<\/p>\n\n<h3 class=\"wp-block-heading\">Can I get a sliding door to open both ways?<\/h3>\n<p>Yes \u2014 pocket-sliding systems disappear into the walls on both sides, giving full opening. Premium spec only \u2014 typically \u00a38,000+ for a 6m opening. Not worth it for most homes; the marginal benefit over a 4-pane configuration with one moving pane each side rarely justifies the cost.<\/p>\n\n<h3 class=\"wp-block-heading\">Do sliding patio doors need planning permission?<\/h3>\n<p>Replacing existing sliding doors in the same opening: no. Creating a new opening or significantly enlarging an existing one: yes if it affects the building&#8217;s facade in a planning-restricted area, or always if listed\/conservation. Building Regs apply regardless via FENSA\/CertAss notification.<\/p>\n\n<h3 class=\"wp-block-heading\">How long do sliding patio doors last?<\/h3>\n<p>20\u201330 years for the frame; the rollers and runners typically need cleaning\/lubrication annually and may need replacement every 10\u201315 years. Sealed glass units same as windows: 10\u201325 years. See our <a href=\"\/glazing\/index.php\/how-long-do-double-glazed-windows-last\/\">window lifespan guide<\/a>.<\/p>\n\n<h3 class=\"wp-block-heading\">Can I finance a sliding door install?<\/h3>\n<p>Yes \u2014 most major installers offer 0% finance for 12\u201324 months on installs over \u00a32,000. Beyond that, interest-bearing 5- or 10-year personal loans are common (see our <a href=\"\/glazing\/index.php\/double-glazing-finance-uk-2026\/\">finance guide<\/a>).
