What is a potential issue with corner strips if not done properly?

When corner strips are not installed correctly, one of the primary concerns is that they may have openings that allow air and moisture to enter. This is significant because proper sealing is essential in construction to prevent water infiltration, which can lead to various structural problems, including rot, mold growth, and insulation degradation. If the corner strips are not tightly fitted, gaps can form, enabling air drafts and moisture penetration that compromise the integrity of the building envelope.

While discoloration, mold growth, and warping are valid concerns relating to building materials, the critical issue directly associated with improper installation of corner strips centers around the potential for openings that compromise the building's defense against environmental elements. Thus, ensuring a tight, secure fit of corner strips is crucial in maintaining both the durability and energy efficiency of the structure.
