Three Things Roof Insulation Must Do
1. Stop Cold
Winter temperatures turn metal, clay, plastic and tile roofing cold. The cold transfers through to the roof resulting in a higher heating bill.
Any roof that uses fiberglass insulation rather than Prodex Total will have moisture issues (typically hidden behind facing), Loss of R-value (consequence of the moisture) and heat gain U.S. Department of Energy: "The R-values of some insulations also depends on...moisture accumulation."
U.S. Department of Energy: "Reflective insulation incorporates radiant barriers -- typically highly reflective aluminum foils -- into insulation systems that can include a variety of backings, such as Kraft paper, plastic film, polyethylene bubbles, or cardboard, as well as thermal insulation materials."
The R-values of reflective insulation and mass insulation are based on the same fundamental equation: The ability to stop heat transfer. Measuring the R-value of reflective insulation vs. fiberglass.
2. Prevent Radiant Heat Transfer
Summer sun rays hitting the roof material radiates downward (inside). It can make it unbearably hot inside. Most roof materials magnify the heat of the summer.
Prodex Total reflects 97% of the radiant energy (primary source of heat flow) that strikes it. Each unit of radiant heat energy that is reflected away from your home or building in the summer, and each unit that is reflected back during the winter, means less operation of your heating and air conditioning system - Less wear and tear on your equipment - Less money you pay in utility costs. Fiberglass and spray foam insulation do not prevent radiant heat transfer.
3. Prevent Condensation - Roof Vapor Barrier
It can seem like a tropical rain forest under an unprotected metal, clay, tile or plastic roof. It's worse on those days where there is a greater contrast between temperatures at night vs. day. The morning sun hitting the cool roofing material can create a drip. When warm air comes in contact with the cool material, condensation occurs. A temperature difference between the outside and inside of your roofing material creates condensation - Similar to what happens when you have a cold can of beer outside on a hot day.
A vapor barrier (moisture barrier) refers to any material that prevents moisture from passing through the walls or roof of a building. This material can be plastic or better yet, Prodex Total Insulation - 0.2 inch (5mm) closed cell polyethylene foam covered on both sides with reinforced foil. Prodex Total Insulation (Vapor Barrier, Class 1. perm<0.1 ).
Prodex Insulation Prevents Rodents, Bugs and Birds from Nesting
Unlike fiberglass insulation, Prodex does not provide for the nesting of rodents, bugs and birds. Rodents, bugs and birds aren't able to digest the aluminum.
Prodex Total Deadens Sound of Rain and Hail
Most roofing material exaggerate the sound of rain and hail. Prodex has excellent sound deadening.
