@lebanonsusa Fadi BouKaram, I'm an American who grew up in Beirut. Just planted a Cedrus libani at our property in northern Vermont. I hope the tree you planted in Lebanon, NH survived! I'm worried about cold temperatures.

I worked for years as a roofer, so I identify with the views expressed in this article. https://t.co/SUtGF20rhi

@betmax Barry, The method you are describing is called "cut-and-cobble." It's a risky way to insulate an unvented roof assembly.

The NY Times usually does a terrible job reporting on home energy issues. This time, a NYT reporter named Jen Miller bucked the trend and wrote an accurate article. Well done! (Quibble: we call them "water heaters," not "hot water heaters.") https://t.co/JATYLa0qqR

For GBA subscribers: My latest blog looks at all of the different brands of heat-pump water heaters that are offered to American and Canadian shoppers. Here is the link: https://t.co/nPTAU7qNZC

Scientists warn: We don't have much time left to enact strict limits on carbon. If we fail, we'll soon face "mass die-offs of coral reefs, widespread drought, famine and wildfires, and potentially conflict over land, food and fresh water." https://t.co/TI1adCUVGF

@skierpage S. Page, Sorry that customer service didn't help you. I certainly hope you decide that your subscription cost was worth it. Most subscribers do.

For GBA subscribers: Have you noticed that code requirements concerning slab insulation are almost impossible to interpret? Read my latest blog, "Determining Sub-Slab Rigid Foam Thickness." https://t.co/1O8b0enjd3

@skierpage S. Page, I'm a journalist, not a consultant. Once you've contacted our customer service department and you've solved your log in problem, you should post your question on GBA's Q&A page.

@Roberta09620693 Roberta, I'm not sure what issue you are talking about. If you are referring to condensation problems at the peak of cathedral ceilings, my article suggests several remedies. Here is the link: https://t.co/Ga9ji6Xyh5

[Martin Holladay @MartinHolladay]

For GBA subscribers: This week, I discuss a building science mystery: Summertime condensation near the peak of a cathedral ceiling. https://t.co/Ga9ji6FWSv

For GBA subscribers: What do you do when you want to add more attic insulation, but the space near the eaves is inadequate? https://t.co/HXqxnGVSux

[Martin Holladay @MartinHolladay]

For GBA subscribers: In this week's blog, I share a nerdy debate comparing the virtues of two different airtightness metrics: ach50 and cfm50 per square foot of building shell. Should code targets be changed? https://t.co/sN1LBCwBqo
