4. ANGLE AND DRAINAGE OF SOLAR TUBES

The angle of installation greatly affects how moisture is managed within solar tubes. Ideally, solar tubes should be installed at an angle that promotes drainage, thereby preventing any water accumulation that could freeze. Adequately angled tubes not only enhance light efficiency but also facilitate the natural flow of condensation away from the interior.

When tubes are installed improperly, they can create pockets where water may sit, leading to freezing during harsh conditions. Conducting regular maintenance checks to ensure the angles are correct is important, particularly after severe weather events such as snow or heavy rain.

In addition to proper angling, it is prudent to inspect the system for potential blockages. Leaves, debris, or snow accumulation can obstruct proper drainage, resulting in water pooling and subsequent freezing. By maintaining clear pathways and ensuring correct installation, homeowners can significantly reduce the risk of issues associated with frozen tubes.

5. MONITORING LOCAL CLIMATE CONDITIONS

Adapting to local climate conditions is a critical component in the prevention of solar tube freezing.
