"As it turns out, we have 10 Halo 99RT housings with Halo 998P Eyeball trim in the kitchen. The trim takes a PAR20 bulb.
And 6 JunoTC44R housings with 12 volt MR16 halogen swivel base trim in the living room.
The Halo housings look to be air tight,…"

I have a client with 16) 4" halogen recessed light fixtures in the attic.I'd like to cover the cans with air tight, fire rated boxes.The plan is to blow cellulose insulation over the boxed fixtures.My concern is about lamp-generated heat being trapped in these air tight, insulated boxes.I'm wondering if the trapped heat might cause a lamp or fixture failure.Any thoughts or experiences on this topic out there?Bachi BrunatoSee More
Cory Chovanec replied to Bachi Brunato's discussion Boxing and Insulating Around Non-ICAT Cans"All good points brought up. My advice is not to leave the lights. When you said halogen I think problem. If they were just standard non IC rated lights I would say box them with appropriate material, put in a CFL.
We box around non IC light…"
John Rising replied to Bachi Brunato's discussion Boxing and Insulating Around Non-ICAT Cans"Hi Bachi,
We have done many projects where we have installed boxes around recessed lights to mitigate air leakage around these areas and have used insulite brand boxes sourced from JR insulation suppliers. They work ok, but we prefer swapping out…"
Bud Poll replied to Bachi Brunato's discussion Boxing and Insulating Around Non-ICAT Cans"This is a topic I have discussed many times, but unfortunately cost is all too often the deciding factor, and it should not be. Code and safety are top priorities. What I have drawn from those conversations is, not all fixtures have been tested and…"

Look into Tenmat - those are designed (& tested) to keep adequate spacing & resist fire

Yes it can as they have a heat…"

Thanks for for the data on the house. It really helps to figure things out to know these things. Sounds like you met the passive house standards for insulation and infiltration.

Terry D. Davenport replied to Bachi Brunato's discussion Savings for Conditioned Crawlspaces"Hi again Ed,
I have been all excited to measure ground temperature in the last couple a' days. My Caleffi idronics came in the mail, and it is on heat pumps. So I found my old notes, and on Dec. 31, 2010, I measured my…"
Terry D. Davenport replied to Bachi Brunato's discussion Savings for Conditioned Crawlspaces"Hey there, Ed.
I think the house is 1200 ft2 on the inside and since the wall wound up 22" thick, it is 1400 ft2 on the outside. Hamilton MT is around 7700 heat degreee days. The Ravalli Electric Co Op used to cost 5.3…"

Congratulations - that is an admirable hea tbill in Montana. A couple of questions: How big is the house? How many Degree Days in your area? What do you pay for Columbia River electricity? What was the blower door number. And…"
Terry D. Davenport replied to Bachi Brunato's discussion Savings for Conditioned Crawlspaces"Hi Ed. Great point in allowing for expansion and contraction of concrete. I am always pouring against an ICF foam wall. This is easily forgotten about. You have reminded me of a detail that I thought of when desigining…"
Bud Poll replied to Bachi Brunato's discussion Savings for Conditioned Crawlspaces"I'm stuck in the in between world for now, not bad enough for extreme measures and not good enough with a hearing aide to communicate reliably.

Ed Minch replied to Bachi Brunato's discussion Savings for Conditioned Crawlspaces"Great info, Terry. I have had similar experiences. The edge of the slab needs an expansion joint so that the expanding slab in hot weather does not push the foundation apart or buckle. This material is usually compressible so has…"
Bud Poll replied to Bachi Brunato's discussion Savings for Conditioned Crawlspaces"I do a lot of free consulting to offset my extremely bad hearing, can't use a phone so I go to their home and talk to them as I can still get by face to face.
