\nCortizo Isolation<\/span>
A roller shutter box designed for Cortizo PVC windows<\/h2>\n <\/span>\n<\/header>\n
The Cortizo Isolation roller shutter box<\/strong> complements Cortizo PVC windows with insulation designed to continue across the whole opening.<\/p>
\n
Two sizes with different reference values<\/h3>
The 200 mm<\/strong>version quotes thermal transmittance fromUsb 0.66 W\/m\u00b2K<\/strong>, while the 160 mm<\/strong>version quotes acoustic insulation up to47 dB<\/strong>. Both have reference E2400 watertightness<\/strong>andP3 wind resistance<\/strong>. Compare the complete test assemblies rather than combining the best figures into one assumed configuration.<\/p><\/div>
\n
Box and window designed to work together<\/h3>
Cortizo Isolation<\/strong> is intended for compatible A 70<\/a>, A 78<\/a> and A 84<\/a> assemblies. Its connection profiles join the box and window within the system.<\/p>
Available space, shutter height and the chosen window determine which 160 or 200 mm<\/strong> assembly is suitable. We check these dimensions when measuring.<\/p><\/div>

Consider the complete opening\u2019s insulation<\/h3>
A highly insulating window also needs a suitable shutter box and perimeter installation. Cortizo Isolation has reference air permeability Class 4<\/strong>andE2400 watertightness<\/strong>, making it an option to assess alongside efficient windows such as Cortizo A 84<\/a>. The manufacturer\u2019s test values are non-contractual references.<\/p><\/div> <\/details>\n <\/div>\n <\/div>\n<\/div><\/section>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\nCommon questions<\/span>
Frequently asked questions<\/h2>\n <\/span>\n<\/header>\n
Can Cortizo Isolation be used with VEKA windows?<\/summary>
It is designed for Cortizo PVC systems. For a VEKA assembly, we assess compatible alternatives such as Vekavariant 2.0 or Eurostar.<\/p><\/div><\/details>
Which Cortizo Isolation size does my opening need?<\/summary>
It depends on shutter height, the rolled curtain and the available space. We calculate the assembly during measurement and compare the insulation values of the appropriate version.<\/p><\/div><\/details>
Can Cortizo Isolation be specified with a motorised shutter?<\/summary>
Yes. A compatible motor and controls can be included as an option in the quote.<\/p><\/div><\/details>
Does Cortizo Isolation provide access for maintenance?<\/summary>
Yes. The box includes an access cover for servicing the shutter mechanism.<\/p><\/div><\/details><\/div>\n<\/div>\n
