The first chart shows that fixed costs remain $50,000 at all production levels from 100 units to 1,000 units. The second chart shows that the fixed cost per unit decreases as production increases. Hence, when 100 units are manufactured, the fixed cost per unit is $500 ($50,000 100).
Plastic Roofing Cements. What is âPlastic Roofing Cementâ? Plastic Roofing Cement is composed of asphalt, fiber, solvent vehicle and sometimes rubber polymer as well as. water displacement additives.
They are often confused with roof cement. To get the terminology right, coatings have the consistency of thick paint and are typically spread over the entire roof with a heavy-napped roller. Roof cement is a dense paste typically spread with a trowel that's used to spot-seal leaks. Legitimate asphalt coatings are used mainly as an overall sealer on low-slope roll roofing -- the kind of roof you might have on a shed. The coatings don't look right or work well over shingles or roofs with a steep slope.
