When it comes to insulating the house, fiberglass tends to be the common form of insulation. However, after comparing fiberglass and spray foam insulation, it’s shocking how fiberglass tends to be the lesser of the two. Although it has deemed reliable over the years, there are way more benefits to insulating your home with spray foam. One of those benefits includes regulating the temperature of your house.

Most flat roofs are not perfectly sloped, causing water to puddle in some areas, in particular around the drains and scuppers. Many roof coatings are not rated or warranted for "ponding water", and thus might fail pre-maturely if exposed to standing water over long periods of time. Serious consideration should be given to the performance and limitations of the coating being selected. Some manufacturers will warranty their coatings including ponding water. Typically, manufacturers for acrylic roof coatings do not include warranties for ponding water, while some polyurethane and silicone roof coatings manufacturers will.
The insulation at eaves level will leave your loft area comfortable for use and free from condensation. By installing the insulation at rafter level, it keeps the loft void warmer and prevents condensation build-up, which can otherwise occur when increasing insulation at ceiling level. The warmer, drier, cleaner roof space eliminates the risk of pipes and tanks freezing. http://m.youtube.com/e/ggLAUsiuI_o
Although spray polyurethane foam has many advantages over other types of insulation, spray foam installation isn’t foolproof. Some builders have reported problems with sloppy foam insulation. For example, some installers have been known to begin spraying before the chemical components are up to temperature, which can affect component mixing and foam performance. When components are poorly mixed, or mixed in the wrong ratio or at the wrong temperature, cured foam has been known to shrink away from rafters or studs, leaving cracks. Some installers rush through their spraying, resulting in voids.
DID YOU KNOW? Spray FOam insulation out-performs conventional insulation materials because they (conventional insulation materials) trap still-dry air and if that air moves or becomes wet, the thermal resistance can drop by 50%. Spray Foam protects against air infiltration, which can increase energy costs in buildings by 10 to 40%. Eliminate these drafts and live in a more energy-efficient, comfortable and healthier building by choosing spray foam insulation. https://www.youtube.com/watch?v=ggLAUsiuI_o&feature=youtube_gdata
Most closed-cell spray foam is now formed using hydrofluorocarbon (HFC) blowing agents that have high global warming potential, partially or completely offsetting the climate benefits of the energy savings they can offer. In the United States, HFCs are scheduled to be phased out by January, 2021. A few spray foam suppliers have started supplying spray foam blown with hydrofluoroolefin (HFO) blowing agents without this problem as of early 2017.
how much does it cost for spray foam insulation
Here's a simpler, less expensive alternative: Cut some 2-inch-thick rigid-foam insulation and glue it to the subfloor between the joists or support it with nails driven partway into the joists. Then fill any gaps between the edges of the foam boards and the joists using the canned spray foam sold at home centers or hardware stores. An even easier option is to nail the foam panels against the bottom edge of the joists and seal the joints with canned foam, but you'll lose some headroom and access to any pipes and wires between the joists. As with spray-foam kits, protect yourself and the floor from the dripping globs of canned foam. A full face shield, gloves, and a hat would be a good start.

This is a one coat system for your RV. The result is customers saving labor costs and material costs since many of the other systems on the market require multiple coats and provide no warranty. Stop recoating you RV after just three years with elastomerics and acrylics and get the product with the industry's leading warranty. Over a 26 year history of proven success in the marketplace. Regarding dry times; it normally takes about two days above 50 degrees for the material to develop a skin and then 7 days for a full cure. Should the temp drop below 50 you would need to add that time to the overall cure. So for example if it drops below 50 degrees over the next 15 hours add 15 hours to the overall timeframe. The higher your daytime temperature gets the quicker the material will dry. If you get an unexpected shower no need to worry. Also in the event of that unexpected shower the product is already waterproofed. In fact that ponding rain water will even start curing underwater! Easily applied with a squeegee and a roller a 24 ft unit should take you approx two hours to apply. Note that once you mix the catalyst you have approximately a 3-4 hour pot life depending on your daytime temperatures. The higher the temperature the less pot life you have. During your initial cleaning of your RV you may wish to consider adding 2 cups of bleach to kill any surface mold/mildew along with a standard detergent such as dawn dish washing detergent or Simple Green. You will want to be sure that any oils or fats are removed as they will cause the existing epdm roof to swell. That swelling most of the time will go down but in some cases it will not and that is not covered under warranty. Applying one coat of the proflex primer will alleviate that issue.
