FLASHING & DRAINAGE
Once we talk about cavity wall construction, obviously water will migrate from the exterior to the interior cavity, and what do we do with it? Most people think flashing's not a bad idea.
Copper flashing obviously you know why we love that we make it. Laminated copper flashing is easy to work with. Longevity - it will last the life of the wall and my company will give you a guarantee in writing that it will last the life of the wall.
Most brick walls today, they're looking for a 50-year guaranteed minimum many of them up to 100-year minimum on the actual brick, grout, mortar and all that stuff. If the flashing is not working, how do you fix it? It's not like a door or a window where you can pull it out; you've got to tear the walls out. That's the only way to get in there and really fix it.
I think it all comes back to: flashing should last the life of the wall. Peel and sticks don't, PVC doesn't, and stainless will, but it's hard to work with. Copper's the one thing that they used for so long that will last the life of the wall. It's not the cheapest, but it will last the life of the masonry.
Keene Building Products
GOOD QUALITY commercial masonry construction is done at a pretty high level," said Jim Keene, president of Keene Building Products. What I see in the majority of the mistakes is on the multi-family residential condos and townhouses, and the single-family homes. It's just a case of putting the traditional things that go in: weep vents, flashing and proper details around the windows and doors. Those are the kinds of things that don't get done properly in residential construction.
There's no huffing & puffing about the simplicity of carpentry installation!
