Technical Information

• FOAMULAR

250 XPS insulation is a non-

structural material and must be installed

on framing which is independently braced

and structurally adequate to meet required

construction and service loading conditions.

• FOAMULAR

250 XPS insulation can be

exposed to the exterior during normal

construction cycles. During that time

some fading of color may begin due to UV

exposure, and, if exposed for extended

periods of time, some degradation or

“dusting” of the polystyrene surface may

begin. It is best if the product is covered

within 60 days to minimize degradation.

Once covered, the deterioration stops, and

damage is limited to the thin top surface

layers of cells. Cells below are generally

unharmed and still useful insulation.

• FOAMULAR

250 XPS insulation has a

maximum service temperature of 165°F.

Install only as much FOAMULAR

XPS

insulation as can be covered in the same

day. For horizontal applications, always

turn the print side down so the black print

does not show to the sun which may at

times act as a solar collector, raising the

temperature of the foam under the print to

an unacceptable level.

• Do not cover FOAMULAR

XPS insulation

either stored (factory wrapped or

unwrapped), or partially installed, with dark

colored (non-white), or clear (non-opaque)

coverings and leave it exposed to the sun.

Examples of such coverings include but

are not limited to lter fabrics, membranes,

temporary tarps, clear polyethylene, etc.

If improperly covered, and exposed to

the right combination of sun, time and

temperature, FOAMULAR

XPS insulation

deformation damage may occur rapidly. See

Owens Corning publication “Heat Build Up

Due to Solar Exposure” (Pub. No. 10015704)

for more information.

• This product is combustible. A protective

barrier or thermal barrier is required to

separate this product from interior living

or conditioned spaces as specied in the

appropriate building code.

• All construction should be evaluated for

the necessity to provide vapor retarders.

See current ASHRAE Handbook of

Fundamentals.
