Do you remember those good old days when pink panther was the only available and most celebrated product for home insulation? As you can notice, those days are now somewhere in the past. Things have radically changed because today building scientists, contractors and homeowners are more obsessed with foam insulation.spray-foam-insulation-green-house-plans

Apparently, this new insulation is quite popular and is manufactured in various forms. For now we shall look at the differences between the rigid and spray foam more specifically comparing the closed cell spray which needs a mixture of 2 components at the nozzle of application and the rigid foam_ insulation boards which are made in various thicknesses.
Owing to their mutual significance in boosting home energy performance it can sometimes prove very challenging to make a decision on whether the rigid or spray foam is more suitable for a attic insulation.
For money home owners, insulation is deemed as the most cost effective and practical way to make houses energy efficient. Green Energy Solutions are expets  in insulation and he will guide you through your entire house’ insulation requirements, what to insulate and all the safety precautions to take with insulation.

For a comparison of these insulators, listed below are the PROS and CONS of both options:

The PROS for the Two-component spray foam

  • It is dual purpose as it provides both insulation and air sealing. The foam expands filling gaps and cracks
  • Depending on the insulation, it has a higher R-value per inch
  • It takes less time to install
  •  Once cured, it stays in place without shifting or falling out of place

The CONS for the Two-component spray foam

  • It is messy as the overspray can deposit foam in areas that will require cleaning.
  • It is a must to wear respirators and protective clothing during installation
  • It is sensitive to temperature as cold temperatures can tamper with curing or foaming action

PROS for using Rigid foam insulation

• It is less complex and easy to work with
• Safer as no respirators or protective clothing is required
• Provides both insulation and air sealing for seams between sealed with tape
• Compared to the spray foam it is less messy
• Different thicknesses are available to best suit specific R-value requirements and the type of application
• it is easier to cut and install panels at different temperatures
• There are no harmful during installation hence safer to handle
• It is best suited for insulating crawl space and basement walls
• Rigid foam panels like SilverGlo provide for a radiant barrier for additional energy saving
• It is a rigid foam installation requiring no modifications

The CONS for Rigid foam installation

• It has different R-values based on the type of Rigid foam ranging from a low of R – 3.8 per inch to a high of R- 8 per inch
• Some application of the Rigid foam take longer time during the installation than the spray foam
• It might require the application of a single component of the spray foam around the edges of the rigid foam to hold them in place

    so with your Dr prescription, you created a nother room to storage boxe’s,why not let the lower level be where we stay and leave, Oh i know why? it because i don’t need your product!

    Wow, I love what I learned from this video, 🙂 I’m gonna do this to attic by my self

    DrEnergySaver Cleveland. can i seal my attic like you did in this video with 3/4 inch foam board or 3/4 R-matte plus 3 R3.2 that is sold at home depot. if so, would i have to make a box in the raffters so that my attic fans and pull the heat out in the summer. i live in deep deep south texas were the days are 105 and the nights are in the mid 90. and winter time it doesnt get to cold, heck i went to the beech on christmas day. thank you -mike

    why would you want your attic to be warm in the winter and cool in the summer? Wouldn’t that mean you’re wasting energy by heating and cooling your attic. It seems it would be more effective to place it on the floor of the attic to keep those temperatures in the home instead of leaking from the home into the attic…….

    What about vent’s?

    no sense in asking anything here, they dont respond back.

    this is a good approach “if you want extra storage space or you have hvac equipment in your attic”. Why didn’t you understand this? oh because you don’t fucking listen.

    the soffit will be open venting air to the ridge vent.

    WHY would you want to heat and cool unused space?

  10. Jorge Flores April 25, 2013 at 11:05 pm #

    What he means is ,to thinking that the addict will be a additional floor in the house so insulated like a room.

    In theory, you’d loose less heat by just insulating the ceiling, which has less area. But with many houses, the leakage from ducts, light fixtures and hatches, plus problems with air and water infiltrating the ceiling insulation, make the losses through the ceiling greater than they would be by just insulating the whole attic. I’d rather just see the attic finished off and usable; that would get rid of all the pest, moisture, leakage and fire-risk issues with vented attics.

    What type of foam is that foam board? The highest R value per inch is polyisocyanurate board at 6, so 4 inches of that stuff is 24. But it doesn’t look like polyiso board, so it’s probably less. At any rate, Ohio uses the 2009 IECC which requires a minimum of insulation level for the ceiling of R38. You should add something to that to get it up to the code minimum, like another layer of whatever that stuff is.

    I don’t know how expensive this is but it looks like a lot! I know it would be an absolute nightmare to install. Spray foam is definitely an easier install and most likely more affective. Probably cheaper too. This looks like it would work well though. Ive been in the insulation business for ten years and I’ve never seen this before.

    Spray foam doesn’t have the radiant properties though, so heat will transfer to and from, but very slowly. The reflective surface bounces much of the heat energy back out, I believe.

    then you have to heat and AC your attic that your never in. not worth it!

  18. randy carreiro September 3, 2013 at 9:28 pm #

    you have to get some egress. and even though you can get it in the gables or roof .your limited.( iknow dormers ,etc.not going there), then your three stories up on a colonial . roof at least a 10 pitch. hope you dont need to get anyone challenged(for whatever reason ) its not reccomended..

    I’ve seen new colonials with finished space in the top half-story, but I imagine it’s only allowed for office, den or storage space in some places; I wouldn’t want a disabled person sleep at that level, but there are plenty of 3rd+ story apartments. In Europe, they seem to be more willing to make use of attic space and you almost never see the kind of explosive attic bonfires that are common in newer houses here. As I see it, the less void space, the better.
