AI Technical Summary

Technical Problem

Existing methods for stacking roof windows are inefficient, as they require substantial packaging material and result in increased load on lower windows, making it impractical to stack multiple windows safely and minimally.

Method used

A stack of roof windows using a sheet member made from a shock-absorbing material with retainers, where the sheet member has an upper and lower surface, and the retainers have attachment and engagement sections to securely position the roof windows.

Benefits of technology

This method allows for safe stacking of multiple roof windows with minimal material consumption, distributing the load effectively and preventing damage to the windows during storage and transportation.

Abstract

A packaging kit for use in stacking roof windows. The kit comprises at least one sheet member and a plurality of retainers. The sheet member is made from a shock absorbing material and may comprise a plurality of openings. Each retainer comprises an attachment section and an engagement section, said attachment section being configured for being attached at an upper surface of the sheet member, for example being inserted in one of said openings, and said engagement section being configured for engagement with a roof window arranged on top of the sheet member. In use, the sheet member is arranged on top of a first roof window, at least two retainers are attached to the sheet member, and a second roof window is then arranged on top of the sheet member so that it comes into engagement with the retainers.
