Flat glass prices climbed .3 percent from August to September, according to the latest Producer Price Index Report issued by the U.S. Labor Department.

It’s welcome news for an industry that saw prices fall by the same amount in the prior period of July through August after rising just .1 percent the month before.

Economic recovery continues to come slowly to the construction industry, which saw its import prices increase by 1.6 percent over the past month. Construction prices had slipped .2 percent in the period between July and August. The climb, however slow, is still a 3.3 percent improvement from where industry numbers stood in September 2012.

The import price for construction machinery and equipment also enjoyed a bump, rising .2 percent after stagnating or slipping throughout the summer.

Other positive gains were obvious in the seasonally-adjusted prices of construction materials, which rose to their highest levels since spring.
