The latest Producer Price Index (PPI) from the U.S. Bureau of Labor Statistics (BLS) was released last week, with prices for materials used in door and window manufacturing mostly steady from March to April, but with small ups and downs on a year-over-year basis.

In April, the monthly PPI for flat glass in the commodity category clocked no significant change from March 2024, while dropping 2.2% on a year-over-year basis. According to BLS, the commodity classification “organizes products and services by similarity or material composition, regardless of the industry classification of the producing establishment.”

The index for flat glass manufacturing in the industry classification mirrored the flat glass commodity category, with no change from the previous month, while dropping 2.2% from 2023. The industry classification measures “changes in prices received for the industry’s output sold outside the industry (that is, its net output).”

The PPI for metal windows remained steady from March to April, while dipping just 0.5% from the April 2023 report. Prices for metal doors and frames also flatlined from March to April, but showed an improvement of 1% since last year. Prices for wood window units showed no change from the previous month but were up 3.2% on a year-over-year basis. Prices for wood doors for interior and exterior applications reflected a small increase in April 2024, up 0.8% from March. That carried over to an increase of 2.5% from April 2023 pricing.

The price for thermoplastic resins and plastic materials inched higher—by 0.9%—over March 2024, but saw a drop of 5.3% from April of last year. Prices for fiberglass plastic products showed no change from the previous month but had an increase of 2.2% over the previous April.

The cost of builders’ hardware, which includes hardware used in doors and windows, rounded out the no-change party from March to April, and even dropped by 0.9% from April 2023.
