shutter box<\/strong>can be a weak point even after fitting efficient windows. An<strong>insulated PVC shutter box<\/strong> helps reduce heat transfer and noise through the opening.<\/p><div class=\"vv-seo__sec\">\n<h3>Monoblock or built-in box?<\/h3><ul class=\"vv-seo__list\"><li><strong>Monoblock systems<\/strong>, such as Vekavariant 2.0, Eurostar and Cortizo Isolation, are manufactured and fitted with the window as one assembly. The chosen system determines the sealing, access and dimensions.<\/li><li><strong>Cortizo Cassonetto<\/strong> is an access-cover solution for a roller shutter recessed into the wall. We assess the existing masonry box and its insulation before specifying it.<\/li><\/ul><\/div><div class=\"vv-seo__sec\">\n<h3>Compare the reference insulation values<\/h3><p>An uninsulated old box can transfer considerably more heat than a modern window. The systems in our range quote <strong>Usb values from 0.66\u20130.97 W\/m\u00b2K<\/strong>and acoustic insulation of<strong>34\u201347 dB<\/strong>, depending on the model and tested assembly.
