The seasonally unadjusted prices for materials used in glass and glazing manufacturing were positive in October and in year-over-year price changes, according to the latest Producer Price Index (PPI) from the U.S. Bureau of Labor Statistics (BLS).

In October, the monthly PPI for flat glass in the commodity category was up 2.6% and 9.8% from October 2020. 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 October index for flat glass manufacturing in the industry classification also increased 4.6% from September 2021 and rose 15.5% 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 were up from last month’s PPI report. That index, in the commodity grouping, is up 38.8% from a year ago and up 1.6% from September. The index for ornamental and architectural metal product manufacturing, in the industry category, increased a significant 18.4% from September and 54.2% from October 2020.

The PPI for metal windows increased 1.0% and climbed 15.0% compared to the October 2020 report. The price for metal doors and frames is also up, 1.2% from September and 24.4% for the year.

The cost of builders’ hardware, including glass and glazing, also slightly decreased from the September 2021 report with 5.5% and rising 17.1% over October 2020.
