They chased us for a year to represent their spray polyurethane foam insulation line including their Walltite® insulating air barrier product. Once we saw a demo of the product and reviewed the benefits of spray foam in general, we were hooked. You will be too. It is currently being installed on a dozen projects in New England and seems to be the only reliable solution for installing air barriers and insulation on the interior side of precast concrete veneer panels. 
When the Mass Commercial Building Code changed to require air barriers, we saw a problem with the existing, commonly used veneer anchors. We looked at all of the U. S. Company’s anchors, saw shortcomings in all of them and were even asked to present on our observations and opinions at the BSA BEC and Build Boston. The industry needed a good veneer anchor system for projects with air and vapor barriers so we took a look up North in Canada since they have been using air barriers for years and found Blok-Lok. They also have a complete line of masonry stabilization anchors to boot.
We needed to add a weep baffle product to our line of products but were sold on the keystone profiled product that we felt set the standard for the industry. Then we were shown a test report that proved that straight strip woven weep baffle performs just as well as keystone profiled weep baffle. Keene made the product along with many other drainage solution products. They also make the most innovative sound mat products and accessories so we decided to take on the line. We came up with a few ideas for new products and applications and Keene has embraced them and now offers them. Besides, Jim Keene is great guy and we really like him.
