insulation

Dumb question, I know, but the rolls of insulation I'm using are just three inches too short for the space. The obvious answer is just to stuff an extra 3" into the remaining space, but it's in the hard-to-access corner of a peaked roof. I could cut each roll in the middle and have a little path...

I have a SMALL job -- wood shop in my Metal shed. 400 sq ft. Planning to use LANDSCAPING FABRIC instead of the more expensive and huge minimum roll size of standard fabric normally used. Has anyone actually tried this instead, just by chance? Porous plastic material to allow water to pass...

I'm insulating a older house. The joists in the attic are both close together and unevenly spaced (between 14 and 14.5" apart, or 16 and 16.5" center line). I'd like to install r-38 or greater, but I'm having a hard time finding anything that fits. Knauf makes a 15" r-38, but it costs nearly...

I have a section of finished wall in my basement that is not insulated, where the stairs run alongside the foundation wall. There is roughly 3" of space between the drywall and concrete foundation wall. At the landing there is a short wall that has about 2.25" of space between the drywall and...

Hi all, we live in Michigan and I'm insulating our attic. Im laying R38 Faced Batts down, with Unfaced R25 crossing over the top, and then rolling unfaced R13 over the top in the same direction as the R38 Batts to get to 20 inches. 20 inches at R2.9 per, puts me in good shape. It's probably a...

I have single-hung windows in my apartment. In all of them there are large gaps between the fixed upper part and the moving lower part of the window on either side towards the frame. It's due to these weird L-shaped cutouts on the bottom edge of the upper fixed part of the window. I've attached...

Hello I plan on doing a reno on a double brick home. The walls are presently sheet rock with plaster on top. It is a late 50's early 60's bungalow. I live in southern Ontario. Option 1: Rip down all the plaster and furring strips and reframe. What is best practice with respect to framing...

Hello, I have a question about venting a half attic situation. this is a new construction with a mono pitch (skillion) roof. The low angle of the roof will be an attic space (roughly 24' x 12') with the higher section being a half floor useable space (24' x 12'). I'm wondering for the roof...

Hi folks, I'm working on the top floor of my 1905 fixer upper foursquare in Pittsburgh, PA. One of the jobs is to make the temperature much more comfortable, as it has no problem reaching triple digits in the peak of the summer. I'll be adding a whole house fan to pull the cooler air from the...

While drilling a hole into my bedroom wall to hang something, I accidentally drilled a little too far and pulled out some insulation. Not a lot, about a dime sized amount. It's interior drywall and now the hole is plugged with an anchor & screw. I assume this isn't something to worry about but...

Hello, I have a flat roof over my one story kitchen in Marin, California. The previous owners hadn't detailed the roof structure, but we believe there is no insulation, just the beams and the exterior tar roofing. In the summer, this roof gets direct sunlight and it leaves our kitchen about 90...

My home's insulation is totally inadequate. It has some sort of blown in cellulose fiber insulation. When I moved some of the laid in place pieces of plywood looking for a wiring fault, which I found by the way, I saw that the grey white fibers are now compacted down to 2 inches at most. Is it...

I have read just about everything I can on insulating basement walls on the internet. Unfortunately there is conflicting opinions and recommendations just about everywhere which makes the entire thing more confusing. Figured I should ask my specific question here to see if I can get any...

Hey everyone. I have two technical questions about insulation and house wrap I'm finding different views on. Location: Quebec. 1. Is it better to wrap Tyvek OVER exterior EPS insulation boards or BELOW? 2. I will be using 2x12 rafters for a vaulted ceiling. My plan is to put R-31 batt...

Hello. I'm new here and I'm new with insulating my home. I've heard it's really good for my home. Anyway, is there any good insulation suppliers you can recommend here in Australia. I'm from Melbourne btw. Also I don't know much of the rules, I hope I'm not breaking any.
