Wall Insulation

Getting to Know Spider Insulation

Posted on April 18,2015 by AlexWilson in blown-in fiberglass

We’ve just completed the installation of a relatively new and (at least in New England) little-known insulation material called Spider. As a reminder, the house we are renovating (really rebuilding) in Dummerston, Vermont, has provided an opportunity to try out dozens of innovative products and materials that I’ve long researched and written about in Environmental Building News.

Does More Wall Insulation Reduce Cooling Costs?

Adding insulation reduces heat flow. That’s what insulation does. But how much does wall insulation impact the heat flowing into your house during the summer? And is adding wall insulation the most effective way to reduce your cooling bill?

Building in Japan

Energy efficient houses are becoming more common in the U.S., even if progress sometimes seems halting. What about building practices in other parts of the world? Are builders elsewhere more progressive about using new materials and techniques, or sticking to the old ways? We get one take on this question from Eric Matsuzawa of Connecticut, who's getting ready to build a house in a Climate Zone 4A region of Japan. Conditions would be similar to those of Virginia, not especially harsh. But what Matsuzawa is learning about local building practices is giving him pause for thought.

Flash and Batt Insulation

One thing I’ve noticed over the years is that construction methods don't change quickly — and when they do change, the change is apt to be along the lines of current practices. That makes sense. It’d be near impossible to run a business if you were changing your technique and product five times a week. Flash and batt insulation is one example of a new technique being implemented by insulation contractors. Flash and batt is a hybrid insulation approach combining fiberglass insulation and closed-cell spray foam.

Insulating Stud Cavities in Existing Homes

I was about to launch into an article on insulating empty wall cavities in an older house when I realized that the topic is best broken down into two sections: a survey of the products you can use to insulate your wall cavities, and a discussion of installation techniques and methods. I'm just glad I realized that in the first paragraph as opposed to the fifth page. So this article will focus on insulation materials.
