    You can tell HomeEnergyNow has a company using competing products. I hear this kind of BS and arguments all the time. First, it works and I know it since I used it in MY house and have never had a client complain after or not toss out our name and tell people it was worth every extra penny for the product. Second, the Department of Energy has done enough studies showing it works. Finally, you will find closed cell in your coolers, refrigerators and big industrial freezers for good reason.

    As for the claims about codes and etc. in REAL WORLD and not computer modeling, I put foam up against other types of insulation all the time. The second you add in moisture, air movement, protrusions and the rest, they are not nearly as effective. Hint, those models only look at R-value which is zero moisture, zero air movement and testing at 70 degrees. Change those and it still works, others drop by 50% and more with models ignoring that or air gaps.

    You guys still use big, dirty, noisy air duct systems???? so primitiv

    hej..morrons…ever heard of HRV????

  5. HomeEnergyNow September 20, 2012 at 11:35 pm #

    Ever seen how the average home owner takes care of filters? Especially when there is a second one hidden in a box they don’t know is even there. Ever seen how accurately an HRV is calibrated with the average hvac company? Ever seen the average 5yr or less warranty they come with? Think about this morron with two r’s, if every home was super tight with HRV’s how many would be not just working, but working properly? Small %. Should people risk their family health for chump change savings annually?

  6. HomeEnergyNow September 20, 2012 at 11:36 pm #

    btw, HRV is the northern climate version of an ERV, which is obviously dicussed.

  7. daren darensky September 20, 2012 at 11:42 pm #

    I do it by digging 100 feet long pipe in the ground 5 to 6 feet deep.
    The incoming air get cooled or heated ( depend on the season) before its connected into the HRV. That way I get way more efficiancy then 80%. And that way it is very nice to have a very ait tight home. By the way ..are you from US???

    ” a home has to breathe” its like saying a home has to have smal holes to get you fresh air. Com on guys …its 21 century…But anyway I had my fun here. bye now

  9. daren darensky September 21, 2012 at 1:08 am #

    You are so right. If you live in a country ful of morrrrons
    Then it is no point to even explain what filter is used for.

  10. HomeEnergyNow September 21, 2012 at 1:13 am #

    Yeah, because those products don’t have to worry about breathing in the air. Live in a cooler, see how good it is for your health. Tight homes were tried and failed many decades ago, try learning some history. Not only were they bad for the health, they lead to structural issues. I used fiber products in my own home with excellent results, foam might produce similar results, but at what cost? 50% drops, now that is a BS argument.

  11. HomeEnergyNow September 21, 2012 at 1:16 am #

    Guess custom homes would make up more than .01% of the market if people truely prefered them? The proof is in the pudding. People vote with their dollars, they vote spec. That is something that can’t be argued. You simply get way more house for the money. Nothing to get mad about, you could look up the % of new homes that are custom, ask yourself why that is.

  12. HomeEnergyNow September 21, 2012 at 1:28 am #

    That technique has been shown to pollute the air, an no filter made today will stop VOC, which is the only item of worry, outdoor air is healthy, indoor air is not. No filter will make indoor air better for you, since they don’t reduce VOC. It takes very little to pollute one pipe with VOC, multiple small holes around the house reduces the potential of polluting your “fresh” air. Don’t you think that simple idea would be used more if it were safe?

  13. HomeEnergyNow September 21, 2012 at 1:32 am #

    The 21st century with all the finishes, plastics, and electronics is actually the reason indoor air is 5 time more polluted than outdoor air. Is there an alarm if your fresh air fan stops working? Do you have it attatched straight to the HVAC with runs different amounts of time during different seasons? Would hate to see anybody use lawn chemicals or paint anywhere near your single source of fresh air, even a random bird, mouse, or dog shit could pollute it. Sounds real safe.

  14. HomeEnergyNow September 21, 2012 at 1:35 am #

    Do you install ugly miny splits? Where each room has its own unit that provides much more noise than any duct system, has many different filters to change/clean, and costs much more than it will ever save compared with a central system.

  15. HomeEnergyNow September 21, 2012 at 1:38 am #

    There are many different comprehensive computer modeling software. But like most spray foam fans, you just go with your gut…..lol. Defy math/physics with guesses. I have lower useage than my spray foamed neighbor, but hey, he still thinks its better too! Kind of butt hurt when you spend that much extra on a petroleum product and get whooped in performance huh? Its called denial.

  16. daren darensky September 21, 2012 at 1:43 am #

    No …dont tell me you live in the cave. If so, when you make a a fire use your
    entrance as ” air in” and arrange for a secondary opening higher up for the smoke
    out. And be safe

    heat pumps cools and heat. When heating, for every 1 KW in electricity they deliver 3-5 KW in heat. Ever heard the noise of a Daikin heat pump???
    it takes 5 second to replace filter sized 2 feet by 4 inches and without making the trip to the basement. About the cost you are maybe right. I can not compare your
    duct system installed by you, to my mini system installed by me.
    BTW “mini” is correct “miny” is not

  18. HomeEnergyNow September 21, 2012 at 2:58 am #

    Spell check is a way of saying “I”ve got nothing”. Gas is so cheap here, you would have to provide 10kwh/1kwh to compete. Central air is cheaper to install, replace, and most importantly not an ugly box hanging on walls in every singly room, which does not circulate air through a house worth a crap. Tell me, how do you get fresh air to every room? How do you cool your bathrooms or large closets full of VOC emitting clothes or poo’s? How about the annual cost of replacing 5+filters monthly?

  19. HomeEnergyNow September 21, 2012 at 3:07 am #

    Have you heard how quite new central air systems have become with variable speed balanced motors? They use the exact same equipment as your mini split, but they have ducts that reduce the noise doofus. You can’t even tell they are on. Not all filters are in basements, and yes, one filter is much better than many filters. Central air is simply your mini split using noise reducing duct systems, so that argument is retarded. Daikin? Need china to build your systems? Cause your country is too stupid

  20. daren darensky September 21, 2012 at 11:16 pm #

    I rather have a box ( check the sizing of 12 KW daikin) then dirty ducts covered nicely with drywall and talking all together a lot of space, Return air is running between the drywall and you talking about VOC
    When I install a floor heating it is completly no noise, no dust, it does not dry the air like
    forced air because the max temp, is 40 celsius.
    For the A/C I use mini spits, and for ventilation HRV.
    We are from diffrent worlds,
    Do you travel to europe?

    Whats with the fukn music, it’s a distraction at best and takes away from the video.

    About time someone mentioned r values and moisture within open cell poly. I remember installing new walk in freezers at a plant. The old ones were removed and they were full of water from years of condensation and was virtually useless as an insulator.
