Attic I Insulation Help On New Construction
Comments (36)Lzerarc, I have heard of companies doing just what you describe with recessed cans & bath fans. it has been a while, because for the most part we are foaming the roofline. if ducts are in the conditioned living space then attic floor is foamed. here,it is uncommon for ducts not to be in attic..sadly. epic fail on designer/arch imo most of the thread is about open cell. as per post #4 in which OP specifies foam type. I have the same problem in getting foam companies to install 8-9" of open cell sf insulation. on a few occasions I can 'make' them install this depth, but it causes bad feelings with the company & sometimes my client. the line from the foam company is that it raises cost of install. this tatic to me bears explaining. when adding to depth of foam insulation, it does NOT double the cost. to break it down, the homeowner pays for the foam company's set up. getting truck on site, heating the product, setting up the hoses to spray and prep work. once this is done, the cost to add more product is only product cost. it isn't much more time, as spray foam install is fast. set up has been paid for. to go from 3" to 6" or 9", the homeowner only pays for the extra product, and minimal time to install. this was the discussion in going from 3" to 6". foam co would say...double the cost, homeowner would balk. once the homeowner understood that they would be paying for setup etc no matter if 3",6" or more was installed, then we could start the conversation about true costs to insulate more. as for flash & batt, it just isn't happening here. if the foam company is on sit, they aren't there to just spray 1", when they could be on another job spraying more & making more money. if the foam co can't convince the homeowner to install more foam...they simply do not take the job. now maybe if they worked for a builder & had several houses to do with flash/batt. but in my area, the foam salesmen have flat out told me that they won't waste their time doing flash/batt. IMO it isn't a bad way to go...just getting a company to make minimal money when they could be making more for the same amount of time. I'm 100% with you on no recessed lights. this is a trend I keep waiting for its death! personally why Insulation Contact (not IC Air Tight) are even still produced is something I don't understand. even when recessed lights are to be installed under porches, I have homeowner/electrician purchase only ICAT. otherwise the boxes get mixed up during install & types are mixed in the house. upcharge isn't much per case to go IC to ICAT....See MoreTax credit on insulated garage door for new construction?
Comments (2)No, all of the energy star tax credits do not apply to new home construction EXCEPT for the geothermal HVAC and the solar hot water credits. I highly recommend taking advantage of the geothermal credit. It is 30% of the total cost including all duct work and equipment. There is also no $1500 cap. For example, the quote for a high efficiency heat pump and all ducting installed for my house was $9000. The quote for a top of the line geo unit installed with ducting and vertical geo loop was $16000. I got back $4500 in tax credits on that $16000. The net difference was only $1500....See MoreAustin Texas new construction Trane unit bid
Comments (5)IF that price includes all the duct-work thats not bad. You don't want propane for heating. I 2nd tigerdunes recommendations. Propane fireplace is a nice option and a great emergency heating idea and to supplement on rare cold days. Definitely go with heatpumps with electric backup. Heatpumps will serve your climate well (especially with a new well insulated house). So you are getting a 5 ton and 2 ton units? I guppose thats sized right. Do you have alot of vaulted ceilings? I would maybe consider downsizing that 5 ton to 4-tons. You want the highest single efficiency single stage heaptumps. I would verify that with the contractor....See MoreOpen Cell Spray Foam Insulation for new Construction
Comments (59)"madpebs87 "plus then you might actually have to seal some of the holes in the ceilings." Wouldn't you do this anyway? You foam the roof deck/rafters, do nothing to the ceiling for insulation, why would you not seal all the plumbing/lighting etc holes that go up into attic? Great thread (bookmarked) giving me lots of info when i build in 3 years in coastal ga." been out of town so just getting to answer this. when the attic is vented, you absolutely want to seal all openings between living & attic space. when the attic is unvented & foam sealed, then you want air exchange between living & attic space. you can get this exchange from not sealing the openings that trades make & never seal, or seal it up tight and dedicate an exchange air pathway. problem is...seldom does anyone seal these openings, so adding a dedicated pathway is redundant. people think they built tighter than they actually did in my experience. but it is all just a guess until you blower door test to see what leakage actually exists. build tight, ventilate right, and TEST to find out what performance actually is. OP, I have to defer to folks in climates with basements, as we have too high of a water table in La. for basements. I have no hands on experience with basements, best of luck....See More- 3 years ago
