Has anyone found/used a non-PVC peel-and-stick countertop film?  Working with a client on a corporate renovation, and while we've been able to find a non-PVC product for the kitchen cabinets, I can't seem to find one that works for horizontal surfaces.  And they're looking for a cost-effective and quick-turnaround solution so don't want to...

Hi gurus,

Do any of you have preferred portable devices for indoor air quality monitoring? I know it's hard to find apples to apples, but ideally temperature, CO2, VOC, PM2.5, PM5 would be on the list. Mid-level accuracy - better than consumer, not as $ as IAQ professional level. Thanks!

Does anyone have a "healthy material" exterior bleacher benchtop (beyond natural wood or metal) recommendation for a public high school track and field? 

How do we discern between fiberglass, recycled plastic or HPDE?  Is there a rule of thumb on how to advocate for specifying a "not as bad" material? 

The project is in a coastal... Read more

Has anyone used a commercial heat pump water heater for a large protect?  I have found a few manufacturers for this technology, but want to make sure this is a viable and cost approach to electrical eliminate gas on a path to all electric.
