Thread: Insulation

That looks like it's gonna be a very efficient tight house......... Has your mechanical contractor talked with you about installing an ERV to ensure the house is ventilated properly?

yes, I know about the fresh air returns systems. If you have a completely foamed house you must ventilate it properly. I am not doing a completely foamed house. My walls are foamed but my attic is gonna have traditional blown in insulation. Probably gonna have an R44 up there. The reason being is that I have an extremely tall, complicated, and cut-up roofline. I was kinda scared to foam between the rafters and maybe not be able to tell where any future roof leaks may be located. The cost of foaming a big tall attic was another factor. The way I have it figured it would take about 10 years or more to recoup my cost, by then who knows what will be available. The way I see it, if I can't recoup my money within 5 years it's not worth the trouble, BUT, I have been wrong before.
