Glass and and what a Pane it can be.

The International Window Cleaning Association (IWCA) and The Glass Association of North America (GANA) released a joint Glass Informational Bulletin (GIB) which could have been titled a little better.  Construction Site Protection and Maintenance of Architectural Glass is not just that catchy. Anyway, it outlines the need for proper protection of architectural glass throughout the construction process to all general contractors and builders. Okay so this is pretty simple to understand  here is that bulletin that was sent to builders CLICK HERE FOR THE  CSPMAG.

So the Glass Association is really fighting us on this. They say we should use plastic scrapers or not to use scrapers at all. They say use chemicals to get stickers off the glass  ( a chemical that will mess up the seal of the window). IWCA sent an open letter has been sent to the Glass Association of North America in addition to a number of construction, glazing and glass trade magazines. This letter reaffirms the IWCA’s position that razor scrapers are the tool of the trade for cleaning glass. Its just the standard practice   I could not imagine it any other way. It’s an easy fix to clean the equipment where tempered glass is made. The open letter Click here.

To help builders and property owners understand that they may be buying a defective product, and help educate builders about tempered web hgh human growth hormone glass quality problems before they become scratches, window cleaners can now download documents from the IWCA site to be included in a Builder Education Packet. Send this packet of information to builders in your area along with your proposal or marketing materials.

Another great resound  is to study the IWCA’s “Talking Points” posted here, to help understand the IWCA’s position before attempting to explain the tempered glass quality issue to builders and other customers.

Some tempered glass surfaces are highly susceptible to scratching due to contamination with microscopic surface defects called fabricating debris. Tempered glass scratches caused by fabricating debris have distinct characteristics, and should not be confused with other types of scratches. Click here to learn about field identification of fabricating debris scratches.

The IWCA recommends a tempered glass scratch liability waiver for all construction window cleaning contracts, before any work is done. Click here for an example of a Cleaner to Builder liability waiver.

The IWCA also suggests that builders require suppliers to provide quality tempered glass without fabricating debris, so that all glass can be cleaned – without scratching – using the same tools and methods. Click here for an example of a Builder to Supplier waiver.

The IWCA Tempered Glass Informational Bulletin 2004 – Scrapers & Fabricating Debris is the IWCA’s official position.
