So I got a talk with a heating company on a trade show. They have a ceiling heating system that uses small plastic tube filled with water and claim it can "radiate" downward. Now what I understand is that heat rises. So how trueful is their claim? And if it's true then what is the physics behind this?
Hi Reddit community,
I am feeling a bit overwhelmed choosing between foam or batt insulation for my detached two-car garage and sunroom (converted patio) .
The house is a 1957 mcm ranch in DFW.
The garage is just a shell. I want to have it insulated w/ sheetrock up to the sloped ceiling, allowing space between the ceiling and beams to maintain the height. This will be an air-conditioned art studio.
The sunroom ceiling backs up to the roof decking- there is no attic space above it. It gets pretty hot in there.
Two different contractors have told me either to do batt or foam- each preferring one over the other.
The one who prefers batt said foam conceals leaks, doesn't let the house breathe, and is flammable.
The one who prefers foam said foam is much better for conserving warm or cool air in the house.
They are both very similar in price and willing to do either- I just don't know which to choose for each space.
I've been reading more about the need for the roof to be ventilated above the insulation. So many variables to consider!
Thanks so much for any advice/insight you can offer!
Hey guys. I’m looking for an in-depth study on the usage of mashrabiyas for a future project of mine. Preferably one that says by how much (degrees/percent) have they cooled a room/surface. Also maybe a solid guide on patterns/hole sizes etc. I thought it would be a neat low-tech solution for places that experience severe overheating in summer and I need to provide evidence for my argument. If anyone knows anything please share it would help out a lot
Southern Colorado.
My south wall is cooking two bedrooms. I have a temp gun on the way but I can feel it with my hand.
What’s the best way to stop the solar heat? The home is new and very well insulated.
I was thinking of an awning with hooks in the fascia and ground (no poles). That would allow me to remove it for winter (probably won’t cuz lazy).
A pergola would be strange since it’s an area I would never want to hang out. Plus it’s sloped.
This area can get quite windy, so that needs to be taken into consideration.
Looking specifically at Type 2D in the attached detail.
The note calls for (3) layers of 5/8" Type X gypsum board, but visually the exterior side looks like two standard gypsum layers, with the third/outer layer drawn differently and a dashed line through it where the exterior cement plaster is called out.
Would you interpret 2D as:
A) 3 layers of 5/8" Type X plus the exterior cement plaster assembly, or
B) 2 layers of 5/8" Type X plus the cement plaster assembly essentially taking the place of the third exterior layer?
Curious how others would logically read the detail as drawn.
We're considering GO Logic for a small passive house in Midcoast Maine (one of their smaller standard models) and are trying to talk to past clients
If you've built with them, I'd be grateful to hear:
- How the final cost compared to the estimate, and how change orders were handled
- How long it took from design contract to occupancy
- Whether they acted as GC or you hired your own
- Whether you'd use them again
Happy to talk by DM or phone. Thanks.
