Question:
Is there an installation guide for this product? I am trying to work out if it will function on a box profile insulated corrugated metal roof
Answer:
Yes, an installation guide is usually provided with the VELUX ZWC CK02 2000T Roof Window Profile Set. This product is a frame covering/profile set designed for installations where a standard VELUX flashing cannot be used and the flashing is fabricated on site by the installer. It can potentially work with an insulated box-profile metal roof, provided a bespoke flashing is fabricated. The ZWC profile set is specifically intended for roofs where standard VELUX flashings are unsuitable, including metal roofing applications such as standing seam systems and other specialist sheet roofing. For an insulated box-profile corrugated metal roof, the ZWC profile set provides the finished aluminium frame around the window. A competent roofer/cladder can fabricate flashings to suit the profile of the sheets. However, the key consideration is the profile depth of the roofing sheet. Standard VELUX profiled tile flashings are designed for profiled coverings up to certain heights. If the box-profile metal sheets are too deep or unusual for a standard VELUX flashing kit, the ZWC can avoid this issue as the flashing is site-made around the window and roof profile. To give a more specific advice, we would need to know the box profile sheet type (32/1000, 34/1000, 35/1000, Big Six, etc.), the profile height (e.g. 32mm, 35mm, 40mm), and whether it's a composite insulated panel or single-skin sheet with insulation beneath.
