About this product
BITEC SPM-4H is a hot asphalt applied, mineral surfaced, modified bitumen waterproofing membrane composed of carefully selected asphalts (bitumen) having superior modifying characteristics, blended with high quality styrene-butadiene-styrene rubber. The SPM-4H is reinforced with Spunbond Polyester fabric. Features: Impermeable to water Low temp flexibility Puncture resistant Thermally stable Resistant to acids And most bases Excellent adhesion Excellent workability Longevity Spunbond Polyester support, used as a reinforcement in APS4T has isotropic mechanical properties giving the composite membrane similar mechanical characteristics in all angular directions in relation to the membrane surface. Spunbond Polyester fabric will impart the following properties to the composite membrane: High flexibility Tear strength Puncture resistance Mechanical strength Fatigue resistance High elongation Deterioration resistance Dimensional stability SPM-4H incorporates a smooth and even application of fine sand to prevent blocking of rolls And to provide a smooth, acceptable application surface. It can be applied by using hot asphalt, torching or any BITEC APPROVED ELASTOMERIC COLD PROCESS ADHESIVE. After installation of the roofing membrane is complete, the surface may be coated with a BITEC APPROVED ROOF COATING to increase overall reflectivity of the system and/or fire rating. BITEC recommends that a period of at least 45 days elapse before roof coatings are applied. This will effectively allow the membrane To "cure" and accept the roof coating.
