It is a hard fact to be considered that all glass surfaces will stain if stored in wet, humid or corrosive conditions beyond a certain period of time. The possible damages that can occur to glass are numerous and can be found in our “Post Installation, Inspection, and Protection” guide.
To minimize the possibility of any deterioration to fabricated glass, Uniglass recommends that:
- Before any work is started, both the glass Manufacturer and Fabricator are to be consulted for specific recommendations on the site storage, handling, installation, and protection of their materials
- Glass deliveries are to be coordinated, to the practical extent, to minimize on-site storage durations.
- Construction contractor is to be coordinated with to provide on-site, under-roof storage locations that avoid direct rain and water runoff, work areas of other trades, and areas of high traffic and to minimize material movement and handling.
- As such, fabricated glass units of any type; single, laminated or IGU, are to be:
- Protected from external weather elements prior to installation.
- Never to come in direct contact with water sources of any form such as rain, salt water and / or grey or brown water often found at construction sites.
- Fabricated and pre-glazed units are to be transported and supplied to construction site in secure, block, and braced wooden cases. The bottom edges of the cases are also to be above potential puddles of rainwater or other conditions that could cause damage.
- At construction site, secure, temporary covering are to be provided to prevent direct water flow, but ensures ventilation and combats condensation buildup on the glass.
- Fabricated glass units are to be held in storage areas that are not subjected to deposits from concrete and masonry building materials or hard water spouting from various sources at the job site.
- Stored fabricated glass units are not to be exposed to the activities of other trades such as welding, painting, insulating, and fireproofing.
- For records and claim-processing, proof of on-site monitoring is to be established by means of a daily-inspection program for stored fabricated glass units to monitor conditions and ensure prompt corrective action when needed.
- Temporary protective films are:
- To be applied by the installer to the surface of the fabricated glass units and are to follow manufacturer’s guidelines.
- Not to be allowed to remain on the surface of the fabricated glass units beyond their useful life; as removal methods may damage certain types of glass and / or their coatings.
- Once opened, the fabricated glass units’ cases are not to be exposed to direct sunlight as the insulating effects of the glass layers may increase the thermal stress in the glass and may result in glass breakage.
- Finally, submitted rejection claims are reviewed and processed based on relative international standards.
