Although it is a fast and efficient construction system, poor execution can cause <strong>leaks, loss of thermal insulation and reduction of the panel&#8217;s useful life.<\/strong> In this article we analyze the most common mistakes when installing sandwich panels and how to avoid them in order to achieve a professional and durable result.  <\/p>\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n<h2 class=\"wp-block-heading\">The problem: improper sandwich panel installation<\/h2>\n\n<p>One of the most common failures in sandwich panel roofs and enclosures is not in the material, but in the <strong>way it is installed<\/strong>. When the technical recommendations are not followed, problems can appear such as: <\/p>\n\n<ul class=\"wp-block-list\">\n<li>Water ingress due to rain or condensation.<\/li>\n\n\n\n<li>Thermal bridges that reduce insulation.<\/li>\n\n\n\n<li>Movements of the panel due to poorly resolved dilatations.<\/li>\n\n\n\n<li>Premature deterioration of the structure.<\/li>\n<\/ul>\n\n<p>These problems affect both <strong>roof<\/strong> and facade <strong>sandwich panels<\/strong>.<\/p>\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n<h2 class=\"wp-block-heading\">Mistake 1: Inadequate fixation<\/h2>\n\n<p><strong>Incorrect fastening of the <\/strong><a href=\"http:\/\/www.panelsandwich.org\"><strong>sandwich panel<\/strong> <\/a>is one of the most frequent errors. Using non-specific fasteners, an insufficient number of fasteners or placing them out of the proper groove can compromise strength and watertightness. <\/p>\n\n<p><strong>Best practices:<\/strong><\/p>\n\n<ul class=\"wp-block-list\">\n<li>Use approved screws for sandwich panels.<\/li>\n\n\n\n<li>Respect the distance between fixings.<\/li>\n\n\n\n<li>Always place the fastening in the correct structural point.<\/li>\n<\/ul>\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n<h2 class=\"wp-block-heading\">Error 2: poorly executed overlaps<\/h2>\n\n<p><strong>Sandwich panel overlaps<\/strong>, especially on roofs, are critical to prevent leaks. An insufficient or misaligned overlap facilitates the entry of water and wind. <\/p>\n\n<p><strong>Key recommendations:<\/strong><\/p>\n\n<ul class=\"wp-block-list\">\n<li>Respect the minimum overlap indicated by the manufacturer.<\/li>\n\n\n\n<li>Correctly align the panels before fastening them.<\/li>\n\n\n\n<li>Check the direction of installation according to the slope of the roof.<\/li>\n<\/ul>\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n<h2 class=\"wp-block-heading\">Pitfall 3: lack of technical sealing in joints<\/h2>\n\n<p>Failure to apply <strong>technical sealing at joints<\/strong> is a serious mistake that drastically reduces the performance of the system. Without proper sealing, leaks, condensation and insulation losses occur. <\/p>\n\n<p><strong>Professional solution:<\/strong><\/p>\n\n<ul class=\"wp-block-list\">\n<li>Apply specific sealants for sandwich panels.<\/li>\n\n\n\n<li>Sealing of joints, ends and singular points.<\/li>\n\n\n\n<li>Do not replace technical sealing with improvised solutions.<\/li>\n<\/ul>\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n<h2 class=\"wp-block-heading\">Additional tips for proper installation<\/h2>\n\n<p>\u2714 Always read the manufacturer&#8217;s technical instructions.<br\/>Use compatible accessories (trim, flashings, hardware).<br\/>\u2714 Check the flatness of the structure before assembly.<br\/>\u2714 Rely on technical advice if doubts arise.<\/p>\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n<p><strong>Incorrect installation of the sandwich panel<\/strong> can lead to leaks or loss of insulation, even when using a good material. The most common errors are <strong>inadequate fastening<\/strong>, <strong>poorly executed overlaps<\/strong> and the <strong>absence of technical sealing in joints<\/strong>. Avoiding them is essential to ensure an efficient, durable and trouble-free system in the long term.  <\/p>\n\n<p>If you want to guarantee an optimal result, the key is to <strong>install well from the first panel<\/strong>.<\/p>\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe title=\"Errores Comunes En La Instalaci\u00f3n De Panel S\u00e1ndwich\" width=\"800\" height=\"450\" data-src=\"https:\/\/www.youtube.com\/embed\/1vtTsuAlgcg?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" class=\"lazyload\" data-load-mode=\"1\"><\/iframe>\n<\/div><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>The installation of the sandwich panel is a decisive factor to guarantee its correct operation.
