Roof Insulation - For Metal, Clay, Tile, Plastic, Shingled Flat and Pitched Roofs

3 Things Roofing 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 ).


How To Insulate A Roof - Install Instructions

It's a lot easier and less expensive to install a 5mm roll of Prodex than any other roofing material. Also see Metal roof insulation for metal buildings.



How To Insulate A Roof on a Metal Building

It's a lot easier and less expensive to install a 5mm roll of Prodex than a bulky 6 inch roll of fiberglass or spray foam. Pinching 6 inches fiberglass between the framing and sheeting is not easy. It's really tough having to use a wire mesh to hold fiberglass in place on an existing building. Spray foam is not DIY friendly.

Prodex Total can be installed before or after your metal sheeting. For fastest and easiest installation, install before applying your sheeting.

New Buildings: lnstall the insulation over your purlins and girts (sandwiching it between the sheeting and the purlins/girts). Existing Buildings: lnstall the insulation on the underside of your purlins and girts. For instructions: Installing insulation on roof of metal building

Dear Insulation4Less,
Prior to installation around noon in central Arizona the underside of the 12 foot high “R” panel roof measured 150 degrees F. using Infa Red sensor! Once your insulation was installed same test showed 100 degrees + or - 5 degrees. Before, work area temp was around 115 degrees (that's with a 7000 CFM swamp cooler going full blast}! After installation, same test showed temps in the mid nineties. Entirely satisfied with product!

Dear Insulation4Less,
I utilized your website to determine my needs & came up with my plan to insulate the roof of my 1000 sq ft steel shop. Using 1" X 2" furring strips and washered screws to get dead air space we used the prodex insulation and Super Metal Sealant to cover the entire inside roof. I can't believe how much warmer & quieter it is. A two person crew did all the work in 2 days. The highly reflective material actually makes it brighter inside. Quite a bargain over the $5000 wanted to spray on 2" of insulation.

Dear Insulation4Less,
I installed Prodex in my 40'x40'x14' Steel garage when I bought the building it came with the 4" thick 6' wide white vinyl that was hard to work with because of it's weight and bulkiness. The weather was rainy and it was just my wife and I installing the insulation and steel sheeting. Trying to find something easier to work with I found your product I ordered enough to line the entire garage it was grate to work with. When the garage door company cam to install the garage doors on January 02/2010 the temperature outside was 10 degrees and windy. After they had the door tracks fastened enough to hold the doors in place they light there portable gas salamander I was impressed with how quickly it warmed to 40 degrees and healed the heat after they turned it off.
