Mineral Wool Boardstock Insulation Gains Ground

Posted on April 01,2015 by AlexWilson in ComfortBoard

Readers of this Energy Solutions blog may be aware that I’ve been critical of some of our foam-plastic insulation materials. I’ve come down hardest on extruded polystyrene (XPS), which is made both with a blowing agent that contributes significantly to global warming and with a brominated flame retardant, HBCD, that’s slated for international phaseout as a persistent organic pollutant.

Wrapping an Older House with Rock Wool Insulation

Posted on April 01,2015 by Verdeco in deep energy retrofit

When I first met Chris Gleba and Kris Erickson in December 2011 to discuss their plans for a deep energy retrofit, Chris told me that he had been remodeling his modest two-bedroom house in Lowell, Massachusetts, for over ten years. He had painstakingly rewired and re-plumbed the house and had made energy efficiency improvements (including the installation of a high-efficiency natural gas boiler and radiant in-floor heating). He had also devoted much sweat equity towards upgrading the interior finishes of the kitchen and baths.

Installing Roxul Mineral Wool on Exterior Walls

Posted on April 01,2015 by ShannonAndPatrick in exterior insulation

As the landscape around our building site disappears under a rare blanket of snow, the sheathing on our houses has been disappearing under a thick layer of exterior mineral-wool insulation. Known as Comfortboard IS, this insulation has impressed us with its green virtues, versatility, and price.

Exterior Insulation Is Like A Sweater For Your House

Posted on April 01,2015 by user-1048334 in EPS

There are many construction and insulation approaches which allow a builder to create walls and ceilings with high R-values and low levels of air leakage, creating a much better envelope than is achieved with standard framing methods. Structural insulated panels (SIPs), insulated concrete forms (ICFs), double-stud walls, and advanced framing can all produce more energy-efficient buildings than the ol' stick-built number. The one thing they can’t do is to improve the efficiency of an existing house.

How to Finish Exterior Foundation Insulation

Posted on April 01,2015 by ScottG in exterior foam

Energy gurus and building codes routinely recommend these days that foundation walls be insulated. One way of accomplishing that is by adding a layer of rigid foam insulation on the outside of the foundation. And that's exactly what William Poole is planning to do. Most of the rigid foam insulation will be underground and out of sight. But what do you do with that stretch of exposed insulation above grade?

Architects Talking About Air Barriers

Posted on April 01,2015 by ChrisBriley in air barrier

With cocktails in their hands, architects Chris Briley and Phil Kaplan discuss green building and design issues in a casual, pithy format Join the guys for a drink as Chris and Phil look at air barriers — one of “The Big Three” topics (along with insulation and windows) of green construction. Sit back, relax, and be “edutained” — while you work, drive, exercise or do whatever you do while you podcatch.

Getting Insulation Out of Your Walls and Ceilings

More and more builders have realized the advantages of leaving stud bays empty and putting all of a home’s insulation outside of the wall and roof sheathing. If done correctly, exterior insulation can help produce a building that is almost airtight, very well insulated, and almost immune to water damage.
