When to consider Alcover<\/h3>
Cortizo Alcover<\/strong>is an option where an aluminium exterior is preferred to match other fa\u00e7ade elements while retaining a PVC window underneath. The manufacturer quotesUw from 0.9 W\/m\u00b2K<\/strong>and acoustic insulation up to46 dB<\/strong> for the specified test assemblies. Actual performance depends on the glazing, dimensions, hardware and installation.<\/p>
The clip-on cladding provides an exterior covering for the PVC profile. For exposed coastal locations, we also assess the hardware, glazing and installation details.<\/p><\/div>

New buildings and renovation<\/h3>
Alcover can help coordinate a PVC window with aluminium fa\u00e7ade elements, glazing or composite panels. In renovation, it offers a different exterior finish while retaining the underlying PVC assembly. Balcony doors in the same range and a compatible Cortizo Isolation shutter box<\/a> can be considered as part of the opening.<\/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
How do Alcover and AluConnect differ?<\/summary>
Alcover uses a 75 mm PVC frame with clip-on aluminium cladding. AluConnect uses an 82 mm system with a central seal. We show you the assemblies and compare their specific options in the showroom.<\/p><\/div><\/details>
Can Alcover cladding be fitted to any existing PVC window?<\/summary>
No. Alcover is a Cortizo system intended for compatible PVC profiles. Compatibility needs to be checked rather than treating it as a universal retrofit. VEKA AluConnect is a separate alternative system.<\/p><\/div><\/details>
Which exterior finishes are available for Alcover?<\/summary>
The aluminium cladding is available in different finishes. We show you the available samples and confirm the finish for your order.<\/p><\/div><\/details>
Does Alcover\u2019s cladding add weight to the window?<\/summary>
It adds some weight, which is accounted for within the system\u2019s design. The complete sash must stay within the specified size and weight limits for its hardware.<\/p><\/div><\/details><\/div>\n<\/div>\n
