in systems based on <strong>Salamander, Cortizo and Aluplast<\/strong> profiles. Security performance must be assessed for the complete tested window assembly under the applicable EN 1627\u20131630 framework.<\/p>\n<h3>Multipoint locking<\/h3>\n<p>Instead of a single locking point, this system secures the sash at several positions around the frame, helping provide:<\/p>\n<ul>\n<li>greater resistance to forced entry;<\/li>\n<li>better airtightness and watertightness;<\/li>\n<li>more even pressure on the seals.<\/li>\n<\/ul>\n<p>For example, appropriately specified Salamander <strong>bluEvolution 92<\/strong> windows can be configured for RC3 performance. The correct hardware, reinforcement, glazing and installation must all match the tested specification.<\/p>\n<h3>Mushroom-head security cams<\/h3>\n<p>These metal cams engage with matching security keeps to make it harder to lever the sash away from the frame. Higher-security configurations are available across a range of Cortizo and Aluplast systems.<\/p>\n<h3>Key-locking handles<\/h3>\n<p>A lockable handle provides an additional control against unwanted operation and can be useful on accessible ground-floor windows.<\/p>\n<h3>Electronic systems and sensors<\/h3>\n<p>Modern hardware can incorporate magnetic contacts or other sensors that communicate with alarms or home-automation systems.

about window hardware and security<\/h2><\/div><div class=\"fusion-text fusion-text-11\"><h3>How do I choose the right hardware for uPVC windows?<\/h3>\n<p>The choice depends on the window type, required security level and local environmental conditions. Caixilho PVC assesses each project to recommend a suitable combination of profile, glazing and Winkhaus hardware for performance, security and durability. <a href=\"https:\/\/caixilhopvc.pt\/en\/pvc-windows-and-doors-quotes-contacts\/\">Request a free quote for your windows<\/a>.<\/p>\n<h3>Does Winkhaus hardware need maintenance?<\/h3>\n<p>Maintenance is straightforward: clean the hardware periodically, lightly lubricate moving points as recommended by the manufacturer, typically once a year, and check window alignment. This helps the hardware operate well for many years.<\/p>\n<h3>Does hardware affect acoustic insulation?<\/h3>\n<p>Yes. A well-sealed window with even multipoint closing pressure helps reduce sound leakage.<\/p>\n<h3>Which hardware is best for uPVC windows?<\/h3>\n<p>It depends on the opening type and security requirements. Winkhaus, Roto and Siegenia are established manufacturers known for reliable systems.<\/p>\n<h3>Is microventilation included as standard?<\/h3>\n<p>This depends on the hardware range and brand. Some include it; others offer it as an option.<\/p>\n<h3>Can I improve the security of existing windows?<\/h3>\n<p>In many cases, compatible modern locking components can replace older hardware. A technician should check the complete window and confirm which upgrades are suitable.<\/p>\n<h3>Do all uPVC windows have security hardware?<\/h3>\n<p>No. Resistance ratings such as RC2 or RC3 apply only to appropriately specified and tested complete window assemblies, including suitable locking points, hardware, glazing and reinforcement.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Understand how hinges, locks and handles affect window security, comfort and durability, with guidance on hardware brands, maintenance and resistance classes.<\/p>\n","protected":false},"author":1,"featured_media":8946,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[232],"tags":[233,235],"class_list":["post-8940","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-window-guide","tag-upvc-windows","tag-window-security"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.6 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>uPVC Window Hardware &amp; Security | Caixilho PVC<\/title>\n<meta name=\"description\" content=\"Learn about uPVC window hardware, multipoint locks, security classes, microventilation and maintenance.
