Mineral Wool: A Solution to Thermal Bridging

Thermal bridging or the escape of heat through low-performing areas in a building envelope presents a huge problem for builders interested in energy-efficient buildings. One of the reasons that modern buildings are now more energy efficient than ever is that newer building energy codes, like the 2015 IECC and ASHRAE 90.1 prescriptively include the use of continuous insulation in most climates to reduce thermal bridging. While there are many different continuous insulation products and applications, mineral wool is gaining in popularity as an effective solution in minimizing thermal bridging.

Getting 3 ACH50 Without Breaking the Bank

As we reported earlier this year, 36 states currently use a version of the residential energy code equivalent to the 2009 International Energy Conservation Code (IECC) specification or lower. As states work to adopt and implement more recent versions of the IECC (2012 or 2015), some builders may find it challenging to meet the blower door testing requirements of newer energy efficiency codes. Moreover, doing this cost- effectively is a top-of-mind concern. But, builders can leverage existing relationships with manufacturer partners and an energy consultant or HERS rater to keep costs in check and meet airtightness requirements.   

Ron Davis, owner of Ron Davis Custom Homes takes pride in the craftsmanship of the luxury homes his company builds in and around Dallas, TX. The company has a reputation for quality and is committed to energy-efficient building, constructing HERS-rated and Energy Star homes. By working with a top energy consultant and a national insulation manufacturer, Davis developed a successful, repeatable strategy for building airtight, High-performance Homes. The approach allows this high-end builder to meet stricter airtightness levels without breaking the bank.
