The annual PCBC show, taking place this week in San Francisco’s Mascone Center, may not have the largest collection of products, but good selections are there if you look hard enough. Also, its location in the home building industry’s trend-setting state makes it a good place to spot innovations likely to end up in homes across the country.

PCBC 2012 is decidedly smaller, but we spent the day walking the floor and spotted some cool innovations that range from a new rainscreen system to an aluminum and glass interior door system.

Here are 10 products that caught our eye.
