CSI? What's that? Well, it's on the SpacePlus website: CSI SPEC GUIDE
So what is CSI? It's the Construction Specifications Institute.
CSI was founded in March 1948 by the specification writers of government agencies who came together to improve the quality of construction specifications. The Institute’s efforts were essential in improving construction specification quality so that it could meet the demands of the post-war construction boom.OK, so these people produce specifications so that their members can improve the quality of construction in their products. And it's a GOOD thing that the Sliding Door Company belongs to this organization. They display their CSI Spec Guides for Sliding doors and Swing doors right on their website. These guides describe what The Sliding Door Company is specifying for their products... Except that... they DON'T!
Let's have a look at the Sliding Doors Guide first. Section 1.7 WARRANTY:
Hold on... why does this suggest they give a three year warranty? The Sliding Door Company does NOT offer a three year warranty. Why is this statement on their website? This is repeated in the Swing Doors Guide as well. So if they don't offer a three year warranty, why are they suggesting there is a three year warranty on their products?
"Manufacturer's warranty agreeing to repair or replace components used in interior installations, excluding glass, that fail in materials or workmanship within three years from date of substantial completion."
OK, what else is in the CSI investigation. Let's take a look at Section 2.2 - COMPONENTS. We already know TSDC uses a "Proprietary Formula for Aluminum" but what are they saying on the CSI documents?
Material: Aluminum extrusions, 6061 alloy.OK, so this specifies a specific aluminum alloy - 6061. Hold on again... We already saw their engineering documents called out 6063. Which is it? And what's the difference?
