Foam. Let's start with the foam side of the equation first. An open-cell foam (about 0.5-pound density) is the most cost-effective way to insulate, but any opening over 1/16 could cause the foam to expand out onto the roof. It would be better to use a closed-cell (2-pound density) foam because it doesn't expand as much as open-cell and is more. Step 3. Measure the roof area and cut your rigid foam boards to fit by scoring it with a razor knife and snapping the board at the incisions. Most foam board comes in 8 feet x 4 feet sheets, although different sizes are available (8 feet x 2 feet is common). There are typically 10 to a pack. Advertisement You have two questions: 1) Does insulation (1/4″ foil/foam) under a metal roof do any good? and 2) Does foil without an airspace on one side have any value? Answers - 1) Putting insulation at the roof line will ONLY help if the roof is a cathedral type ceiling Leave Gaps between Panels. A roof must be able to breathe. When there are gaps, or channels, between the pieces of insulation, you allow the air to flow between each one. The gaps do not have to be more than 1/8 inch, but they are important to the health of the roof, the insulation, and the house as a whole Traditionally, we've insulated the roof panel to try and keep the temperature on the panel FROM reaching the dew point. We'll add a vapor barrier so the moist air does not flow up through the insulation and condense on the roof. But a preinstalled membrane may be even more effective at removing condensation. The Problem With Using.

1. Select rigid foam insulation boards that are at least 1/2 inch less in thickness than the rafter space is deep if you plan to finish the attic as living space. This allows a 1/2-inch gap at.

You'll wind up paying more and in some cases you'll need to special-order it, but high-density insulation delivers up to 35 percent more insulating value per inch. You can also pack 5-1/2 inch thick insulation into a 3-1/2 inch thick wall to increase its R-value, but the compressed R-19 batt will only yield an R-value of about 17, and it. Continuous rigid insulation is a construction solution that provides a thermally efficient building enclosure. Rigid insulation sheathing is made of a rigid plastic foam that is typically sold in 4x8- or 4x10-foot boards. The boards are available in several thicknesses and R-values; 1-inch and 2-inch thicknesses are common How much overhang do you need on a metal roof? 3: The panels at the eave side of the roof should overhang into the gutters 1 to 1-1/2 inches. If installing metal on a non gutter application you can overhang the panel up to 3 inches. How far should metal roof overhang gutters? 1/2 inches. Do metal roofs require larger gutters Step 6. Install 1 by 3 furring strips over the insulation panels on top of each stud. The furring strips should run vertically from floor to ceiling, or from eaves to rafters, if you are installing them on a sloped ceiling. Use 2-1/2 inch deck screws to drive the furring strips into the foam and the wood framing beyond Measure the area between your spars and drop one piece of ¾ inch foam board and one piece of 1″ inch foam board in these openings. Note: Do not glue the insulation in place. Some glues will deteriorate the insulation and if you ever need to make a repair, you'll find that easier if the foam isn't glued in place

Foam board insulation is easy to use and is a great DIY way to add some insulation. It comes in standard-size 4×8 sheets, and smaller sizes, in many different thicknesses from 1/4 inch to 2 inches. Some types of thicker foam board insulation are available, but they may need to be special ordered of rigid insulation, wood or metal edge trims, perforated metal vents at eaves and ridge, and a new layer of sheathing held off the insulation by 2x4s (see illustra-tion, page 3). The 11/2-inch air channel created by the 2x4s provides sufficient ventilation above the insulation to main-tain a cold roof surface and prevent ice damming Rigid Board Solutions. Polyisocyanurate insulation is a continuous insulation solution for metal building systems. If left exposed (or covered with a liner panel thinner than 22 gage), it is required that the product have a class A fire rating. Advantages: continuous insulation, reduces thermal bridging, durable facings are available, and meets most building codes For example, roof pitch value of 1:12 means the roof rises 1 inch for every 12 inches of roof's length. Multiply the result with the length and height of the building, and you get the total size of insulation you must install. Read also: Types of Metal Roofing - Metal Roof Cos
