The Foil is a blocking on the faces only but a silicone coat may not be UV blocking at all.Here are some thoughts. 1. Installing foam over the drywall would be bad.Where the old walls were taken down you can now see exposed areas of brick (there is no exterior wall sheathing beneath the brick in some areas).I had 1 inch pink board and glued it to the block wall taped it all off then put R-19 batt insulation with plastic stappled it up for a vapor barrior.It depends on whether or not it means the product will weather UV or block UV.Just found out large parts of the exterior have to be replaced.OR is it ok to buy new insulation lay on top of old one to increase R-value.
You want the insulation to be as close to the outside as possible.The link you provided had a lot of information about new construction in hot humid climates.Then, so that I can leave the posts (which are pretty and expensive) exposed, I have framed the top half of the wall (containing the windows) with 2x4s.There was so much moisture we had 1 building engineer conclude that it was the bathroom fan venting leaking into the wall cavity and another told us it was certainly water leaking from the outside.Reply Pat says: November 19, 2010 at 3:47 pm can i put blue board over drywall in the garage ceiling to help insult it, without putting another layer of drywall over it.Sometimes you do need to apply some temporary shoring but not often with this product. 7. Every state has different rules regarding energy codes.
That extra bit really makes a big difference in performance especially in climates with large temperature swings like here in the North East.Reply Tammy Carpenter says: September 4, 2012 at 8:16 am Recently purchased a 4 level, approx 3000 sq ft home with a sandstone exterior in upstate NY.I figure I could seal up the interior well enough to stop any air flow to the exterior using caulk and tape.Can you give me any assistance on what to use in regards to insulating a metal roof.We are anxious to start insulating but I need to do it right.
Reply Tariq Hussain says: November 23, 2010 at 6:13 pm I am in a similar situation where the rooms above garage become freezing cold.Reply Jazz says: July 7, 2010 at 10:49 am hI, My contractor is installing what looks like polyiso panels 1.5 inch R10, behind new vinyl siding on 2nd floor exterior wall.Also I have one wall in that room that is concrete but on the other side of that wall is my basement.The finished side is actually the upper pitched end of a living room with a cathedral ceiling.Reply Todd Fratzel says: September 11, 2014 at 2:01 pm You can simply add another layer.But you gain square footage of living area because their is not any studded wall cavity.As to ISO and water absorption, that will depend on the type of ISO.When a high r-value, above R20, is required in a pre-engineered metal building, one solution is a cavity filled.
We are going with a closed cell insulation in the walls but we would still like to put some rigid foam board insulation outside under the vinyl sided areas.I am unable to find building size sheets in more than 2 inch thickness, so I guess I will have to double the amount of sheets to obtain maximum insulation value.Reply Dick says: January 31, 2011 at 11:57 am I am looking to use this XPS as a thermal break between the concrete floor in my basement and the subfloor.I would like to find a high density foam to put on top of slab under floating pergo-type floor.Making the transition from below grade to above grade and transitioning to the interior insulation without a break it difficult to do properly.Basically you install a piece of foam, then attach the z-channel to the concrete, it holds the sheet in place and gives you a place to screw drywall to.The big issue with insulating outside is the detail where the foundation comes above grade.
With regard to the compressive strength of the foam board there are several you can choose from.Reply Todd says: June 13, 2011 at 7:19 pm This approach is quite similar to what is going on in the industry with hybrid spray foam installations.
He said he was a contractor and that I needed to seal the concrete before I put up any insulation.The R-value is a measure of thermal resistance, or ability of heat to transfer from hot to cold, through materials (such as insulation) and assemblies of materials.Reply Brian says: July 13, 2010 at 9:36 pm The roof is arced yes.
I want to get the maximum R-value here and create the cold air space between the wood sheathing and the insulation, along with small vents in the soffit to allow air in between this area.Thank you:) Todd says: November 27, 2013 at 5:15 pm Not sure I understand your question.I am thinking of insulating the cellar so I can work down there comfortably.However, that wall will likely not get very cold so if water vapor from the interior space hits the foam it may not condensate.Reply Mark Schmitz says: July 14, 2011 at 10:27 am Thanks for the quick response Todd.The drywall to the finished side is attached directly to a truss.
Reply Mark Schmitz says: July 15, 2011 at 6:16 pm Thanks for your help Todd.Demetrios says: October 16, 2011 at 4:19 pm I have a 1st level room (above grade).Reply Dennis says: August 5, 2014 at 11:19 am Dear Todd: I have an oddball construction project.You seem to have the best understanding of a confusing topic.
That situates the whole room about 2 foot lower than the main house.Reply Angelo says: November 9, 2011 at 12:55 pm Hi Todd, Your suggestions as very helpful re foam board insulation.I will probably have some kind of tray or bucket to put ice on to help keep the kegs cold and so possble water will end up dripping on whatever foamboard I use under the floor of the cabinet.Reply Rich says: August 10, 2010 at 2:12 pm Todd, Thanks for fast reply.Reply Tina T says: August 18, 2015 at 10:12 am Todd, first of all thank you for your fast response.

Rigid Board InsulationReply John says: June 3, 2012 at 1:46 am I am planning to build a room over my attached garage.
The ones I saw appeared to be constructed of a thin wire stud covered by a barbed plastic sheething.Some Box Stores rent insulation blowers which you might be able to use yourself.Do you actually try to get the insulation behind these items, or do you just get as tight as possible to them.If you do this approach be sure all the seams are taped with Tyvek or DOW Construction Tape.All this was done in the fall and two days ago I had to access a drain pipe while doing some plumbing and the batt insualtion on the backside (what was touching the pink board) was soaking wet.
