Should reflective insulation face in or out?

Should reflective insulation face in or out?

If you’re wondering whether to put the foil side of foam insulation board shiny side in or out, consider whether you want to make the space inside warmer or cooler. If you want to make the space warmer, the foil should face inside so it can reflect radiant heat back into the room.

Which is better EPS or XPS?

XPS, at about R-5 per 25 mm, has only a slightly better thermal performance than EPS. However, EPS with the same level of density is less expensive. XPS is usually avoided in areas where materials with less density are needed or where the material, which is not produced below a certain density, is not applicable.

What type of insulation has a foil backer sheet?

PIR, polyiso, or ISO, is a thermoset plastic product typically produced as a foam and used as rigid thermal insulation panel – most often with aluminum foil facing.

What is DuroFoam insulation?

DuroFoam insulation is a closed cell and moisture resistant insulation with a thin film laminated to both sides of the product. It is easy to install and can be used in many applications; exterior sheathing, continuous insulation, basement floor, under slab insulation and cathedral ceilings.

What is the difference between pink and blue foam board?

Main Difference Between Pink And Blue Foam Boards The two products also have the same insulating power. However, blue foam boards are manufactured by Dow Chemical Co. whereas the pink foam boards are manufactured by Owens Corning company. The boards are marketed under different brand names.

Which side of insulation foam faces out?

Hi Kim, Regardless of whether fiberglass insulation is installed in a wall, attic, or crawlspace; the paper facing should always face toward the inside of the home. That’s because the paper contains a layer of asphalt adhesive which prevents water vapor from passing through it.

Is EPS foam closed cell?

Expanded Polystyrene Insulation, more commonly referred to as EPS, is a closed cell insulation that has been around since the 1950’s. EPS is made of 98% trapped air and only 2% plastic, making it an efficient insulator with a small amount of raw material.

Does EPS foam absorb water?

A: EPS is non-hygroscopic and does not readily absorb moisture from the atmosphere. Its closed-cell structure reduces the absorption and/or migration of moisture into the insulation material.

What is the R-value of foil board?

Attached to the face of studs, FOILBOARD® INSULATION PANEL eliminates thermal bridging through the frame and air infiltration. Without insulation a cavity brick wall has an ‘R’ value of 0.5. FOILBOARD® INSULATION PANEL in the cavity will achieve R1. 8 with STANDARD 10 and R2.

Does foam board insulation need a vapor barrier?

Foam insulation usually does not require a vapor barrier. For some foam insulation types, such as closed-cell spray foam and foam board insulation, the insulation itself stops the movement of most water vapor.

Is Durafoam a Vapour barrier?

Vapour Barrier. DuroFoam insulation used as the sole thermal insulation does not require a separate vapour barrier to control condensation within the assembly. thermal insulation in a building assembly the temperature of the inner surface of the low-permeance insulation will be close to the interior room temperature.

Is DuroFoam EPS?

DuroFoam insulation complies with the requirements of CAN ULC S701. 1, Standard for Thermal Insulation, Polystyrene, Boards and Pipe Covering, the National Standard of Canada for expanded polystyrene (EPS) insulation.

Does the reflective Facer increase the R-value of durofoam?

The reflective facer on DuroFoam insulation contains a thin layer of foil embedded within the film. The reflective facer does not increase the R-value of DuroFoam insulation (for additional information see Plasti-Fab PIB 253 – Facts About Thermal Resistance of Reflective Insulation).

How durable is durofoam insulation board?

The addition of the laminated film to the top and bottom surfaces of DuroFoam insulation board provides a more durable product that is less susceptible to damage. The reflective facer on DuroFoam insulation contains a thin layer of foil embedded within the film.

What is durafoam™?

Durafoam™ is our INDUSTRY-LEADING closed cell sponge rubber and plastic foam, and is available as an equivalent to any current or obsolete Rubatex, Ensolite or ANR stock – We ship all over the world. Available in conductive, non-conductive and fire-retardant versions, Durafoam contains co CFC’s or HCFC’s.

Is durafoam DK series closed cell rubber UL approved?
