Carlisle SynTec Systems recently introduced its InsulBase NH and SecurShield NH polyiso insulations. These products provide the same performance characteristics as standard polyiso products but contain no halogenated flame retardants.

Insulation greatly decreases the amount of energy we use, keeping our homes comfortable throughout the year. It’s a critical addition to protecting the environment in our daily lives. Here, we examine the three main types of insulation — fiberglass, cellulose, and foam — and weigh the pros and cons of each.

USG Corporation has partnered with Tremco Commercial Sealants & Waterproofing to create the Securock ExoAir 430 System.

A Denver initiative on the November ballot seeks to sprout more trees, shrubs and even vegetable gardens atop larger buildings across the city, a move that would accelerate a trend that has been embraced by some developers.
