The not seasonally adjusted prices for materials used in glass and glazing manufacturing were a mixed bag in February 2020, according to the latest Producer Price Index (PPI) from the U.S. Bureau of Labor Statistics (BLS).

In February, the monthly PPI for flat glass in the commodity category rose 0.4% from the previous month, and is up 0.8% from February 2019. According to the BLS, the commodity classification “organizes products and services by similarity or material composition, regardless of the industry classification of the producing establishment.

The February index for flat glass manufacturing in the industry classification was unchanged from January 2020. It’s down 0.4% on a year-over-year basis. The industry classification measures “changes in prices received for the industry’s output sold outside the industry (that is, its net output).”

Prices for fabricated structural metal products have increased 0.5% from last month’s PPI report. That index, in the commodity grouping, is down 1.7% from a year ago. The index for ornamental and architectural metal product manufacturing, in the industry category, increased a slight 0.1% from January 2020 to February 2020. It has experienced a 0.1% increase since February 2019.

The PPI for metal windows was unchanged from its January 2020 index. This is the third month of no change in price. However, it has grown 2.1% compared to the February 2019 report. The price for metal doors and frames also was unchanged from January 2020. The category is up 1.3% for the year.

The cost of builders’ hardware, including that used in glass and glazing, dropped 0.4% in February but saw a 1.9% increase compared to the February 2019 report.
