Whether at work or home, indoor acoustic comfort requires freedom from unwanted sound. Exposure to elevated noise levels may disrupt sleep and interfere with activities requiring concentration. Left uncontrolled, long-term exposure to noise levels not otherwise considered hazardous can lead to stress.

Selecting and specifying roof coatings

Progressive Materials 1

Coatings have been successfully used as part of roof assemblies for more than 50 years in the United States. However, in other parts of the world, coatings have been employed for millennia. The development of sophisticated protective coatings occurred in the latter half of the 17th century, when a German chemist found a way to use the stickiness of coal tar as protection on wood and ropes.

Sound-deadening with Sprayfoam: Adding unexpected value with SPF

dreamstime_l_18543982

Insulating walls with low-pressure sprayed polyurethane foam (SPF) is a common practice among builders and architects for various reasons—such as increased energy efficiency, structural support, and overall comfort. One of the ways SPF can increase the comfort of a structure is through the material’s sound-deadening properties, which contractors can employ to bring additional value to a project.

Continuous insulation (ci) has been a component of exterior wall assemblies for almost a half-century in North America. By minimizing energy loss caused by thermal bridging and the risk of condensation caused by water vapor diffusion, exterior ci can improve building durability and benefit the environment. However, using rigid foam plastic comes with certain design considerations that must be reviewed early in the design process.
