Questions & Answers

Is it safer to install faced or unfaced in sttic with can lights?

Asked by Pepperpot April 9, 2021
1
Answer

Hello Pepperpot, the placement of fiberglass insulation with can lights would be based on the light fixture. If the can light IS “IC” (insulation contact) rated, then unfaced insulation can be placed over or in direct contact with the can Light. If using faced insulation, cut the facing back enough that it will not be in direct contact with the can light. If it is NOT “IC” (insulation contact) rated, then the insulation must be kept a minimum of 3” away from the can light and it cannot cover the can light. Thank you for your inquiry!

Hello MissEbbie, compressing the insulation will result in reducing the R-value of the insulation. Please see link below for our Compression Chart to see the amount of reduction will occur. https://dcpd6wotaa0mb.cloudfront.net/mdms/dms/Residential%20Insulation/10017857/10017857-Building-Insul-Compressed-R-Value-Chart-Tech-Bulletin.pdf?v=1428909128000 Thank you for your inquiry!

I wasn't home when these were delivered but many of the bags of insulation were cut in many different areas instead of only having one side open. I've used three of the right bags for part of my insulation project. Great quality insulation just wish I could've bought these separately. Home Depot does allow to have left over bags returned so I'll be using the rest of the bags on the other side of my house. I'll remove all the old insulation and put these down. I don't have a truck to return them, just have to be very careful when doing the other side of my house!

The house we purchased only had about 3 inches of insulation, and our summer electric bill was about $400/mo. Upon install, we noticed an immediate difference in the indoor temperature and how often the AC unit was turning on. Now, with colder weather kicking in, the house sits at 74 with the outdoor temp at 47, and the heater rarely turns on. Our bill this past month was $114 vs the $189 it was when we moved in. Given that we bought this as a Special Buy of the Day, we got it at 40% off and this will pay for itself in about a year. We broke down blown insulation bundles to fill the voids in the existing insulation (up to rafters), faced to cover the parts where there was no existing insulation and unfaced to top it all off. This insulation quality and packaging is excellent. The plastic wrapping is though enough to withstand the tugging/pulling of just getting it where it needs to be without tearing. Once the bundle is cut open, it expands to full dept quickly. If, like me, you're doing the install yourself, make sure to have a helper because each bundle is fairly heavy and bulky for one person to safely get up into the attic. I'd also recommend the ($10) Grip-Rite Stone Wool Insulation Knife because it cut through this insulation like butter and was priceless for this job.

Very easy to install since it comes in 4ft. sections. We Just put it up in our attic so time will tell how it saves on energy costs but we're guessing that we will not be disappointed.

Bought this to use in the flat part of the ceiling in an attic I was finishing. It worked as expected and I didn't have any issues with packaging or shipping. I find the pink stuff to be softer to the touch than some other brands, but it's slightly harder to cut than some since the kraft facing isn't very stiff, but it's not usually a problem.

The batts are a good length to handle. They work great in 10 in rafters. The relaxed thickness is 8 inches or so and they provide r-38 plus whatever products on roof. The kraft facing is stronger than most other manufacturers. You could feel the heat that was no longer escaping.

The insulation was easy to cut and very easy to install. we were able to do the whole room with the product as described. It was awesome and I think we can feel the difference in the room temperature.

Home Insulation Project
My home was built in 1979 with approximately 8" of blown-in insulation (Virginia Climate). Put Owens Corning R-38 on top of existing insulation and it keeps the upper floor cool and quiet. This is an excellent product and has the facing for moisture control. Easy to install and very effective. Would recommend this product to anyone with an older home or to supplement existing insulation. Additionally, this product is well worth the cost because of it's heat resistance and area coverage.
