Heading into the back half of 2026, second-quarter company updates still describe a building products market that is holding together rather than breaking out. Freddie Mac put the 30-year fixed mortgage at 6.76% as of September 10, 2026, a clear step up from the readings near 6.00% earlier in the year. That higher rate is keeping pressure on housing affordability and household confidence, especially for new construction and larger remodel work.
Across the second-quarter outlooks from West Fraser, Weyerhaeuser, James Hardie, Trex, Boise Cascade, UFP Industries, Interfor, Louisiana-Pacific, Builders FirstSource, and others, the message is familiar but more specific than it was in the spring: few companies are counting on a second-half rebound. The operating plan remains margin protection, production that follows actual demand, and selective gains in the categories that are still working.
Housing remains the core driver for lumber, oriented strand board, engineered wood, siding, decking, and much of the sector. West Fraser notes U.S. housing starts at a seasonally adjusted annualized rate of 1.43 million units in June 2026, with permits at 1.37 million units. Company guidance continues to point to weaker near-term residential activity. Builders FirstSource now assumes single-family starts down mid- to high-single digits in its geographies, multifamily starts down mid-single digits, and repair and remodel down 1%. Boise Cascade describes an uneven and competitive second quarter, with affordability constraints, low consumer sentiment, volatile Treasury yields and mortgage rates, and persistent inflation weighing on construction. Builders are still using incentives while staying disciplined on starts and spec inventory. Long-term drivers remain intact—generational tailwinds, an undersupplied housing market, high homeowner equity, and an aging U.S. housing stock—but near-term demand is still being paced by affordability and confidence, with the 6.76% mortgage rate reinforcing that caution.
Lumber and panels continue to reflect supply discipline more than demand growth. West Fraser reiterated SPF and SYP shipment targets of 2.4 to 2.7 billion board feet for 2026, supported by 2025 sawmill closures, reliability and capital improvement gains, and the ramp-up of the modernized Henderson mill. Demand for lumber is expected to remain stable rather than increase meaningfully, reflecting ongoing housing affordability challenges. Interfor says North American lumber markets remain volatile as the economy adjusts to monetary policy, tariffs, oil-price swings, and geopolitical uncertainty. Benchmark prices continued to firm into early third quarter, with July monthly averages up versus the second-quarter average: SYP Composite up $17 per thousand board feet, or 4%; KD H-F Stud 2x4 9’ up $63, or 12%; Western SPF Composite up $43, or 9%; and Eastern SPF Composite up $57, or 10%. Interfor remains positioned with about 65% of lumber produced and sold in the U.S. and only about 20% of production exported from Canada to the U.S. Canfor expects North American lumber markets to stay solid early in the third quarter on lean inventories and transportation constraints, particularly in the U.S. South, before moderating later in the quarter on affordability and macroeconomic uncertainty. GreenFirst Forest Products and Western Forest Products both point to housing affordability as the main near-term constraint, with reduced supply helping support price stability even as demand stays subdued. Conifex Timber takes a similar view of the near term, while still arguing that the long-term fundamentals for lumber remain constructive. Boise Cascade continues to describe commodity pricing as dynamic and says it will monitor end-market signals and align production and inventory accordingly. Rayonier expects lumber shipments of about 1.1 billion board feet for the 11 months of contribution in 2026, including 320 to 330 million board feet in the third quarter, and said it has been encouraged by the improvement in lumber prices from tighter supply/demand and transportation constraints, with July month-end realizations modestly higher than the second-quarter average.
Oriented strand board remains closely tied to housing and repair activity and is still the softer panel story. West Fraser is reiterating somewhat softer North American OSB demand in 2026 and shipment targets of 5.9 to 6.3 billion square feet (3/8-inch basis), after completing the High Level, Alberta OSB mill curtailment in the second quarter. Louisiana-Pacific is guiding to a third-quarter OSB Adjusted EBITDA loss of $45 million and a full-year OSB Adjusted EBITDA loss of $120 million, assuming Random Lengths OSB prices remain unchanged from July 31, 2026 levels. Weyerhaeuser is a bit more constructive on near-term volumes, expecting slightly higher OSB sales in the third quarter with comparable fiber costs and higher unit manufacturing costs, and slightly higher sales volumes for most engineered wood products alongside slightly higher realizations and raw material costs. Broader panel and engineered wood comments remain cautious near-term, with longer-term support still coming from aging housing stock and potential mass timber growth.
Repair and remodel is no longer being described as a clear offset. Several companies now expect the segment to be flat to down. Builders FirstSource projects repair and remodel down 1%. SiteOne Landscapeestimates repair and upgrade down mid-single digits. Fortune Brands continues to assume U.S. repair and remodel down low single digits. Owens Corning similarly expects discretionary remodeling activity to remain under some pressure. Boise Cascade still points to an aging housing stock and elevated homeowner equity as support for the longer-term case, while others say higher borrowing costs and weaker confidence are weighing on near-term project decisions. James Hardie expects organic growth in Siding & Trim from repair and remodel expansion.
Specialty and value-added categories remain the more constructive part of the mix. Trex raised and then reaffirmed full-year 2026 revenue guidance of $1.215 billion to $1.250 billion and adjusted EBITDA of $335 million to $350 million, with third-quarter revenue guided at $305 million to $320 million. Management pointed to disciplined execution, strengthening consumer demand in its category, and the ramp-up of decking production at its Arkansas facility. UFP Industries left its full-year outlook unchanged at the lower end of flat to slightly down unit demand, but continues to expect share gains and momentum in Deckorators’ Surestone business from initial stocking orders, upgraded manufacturing capacity, and expanded distribution. James Hardie raised full-year planning assumptions for Deck, Rail & Accessories to $1.210 billion to $1.240 billion in net sales and $339 million to $357 million in adjusted EBITDA, citing above-market performance and sell-through strength as production aligns with demand.
Siding, trim, and exteriors remain mixed. Broader exteriors still face pressure from softer new construction, while repair and remodel and mix provide some offset. Louisiana-Pacific is guiding third-quarter siding net sales of $460 million to $470 million, up about 5% year over year, and full-year siding net sales of $1.65 billion to $1.67 billion, down about 1%. James Hardie raised full-year Siding & Trim net sales assumptions to $3.226 billion to $3.314 billion, pointing to normalized channel inventories, a fading destock comparison, previously noted repair and remodel expansion, improved mix, and commercial synergies.
Distribution and retail continue to emphasize control over expansion. Home Depot reaffirmed total sales growth of approximately 2.5% to 4.5%, comparable sales of flat to up 2.0%, and about 15 new stores. Lowe’stightened its outlook to total sales of $92.0 billion and comparable sales expected to be flat, with capital expenditures still up to $2.5 billion. Builders FirstSource lowered full-year net sales guidance to $14.0 billion to $14.8 billion, assuming weaker starts and repair and remodel down 1%, with acquisitions adding about 1% to sales and capital expenditures of $175 million to $225 million. BlueLinx expects third-quarter specialty product gross margins of 18.0% to 19.0% and structural margins of 8.5% to 9.5%, with average daily sales volumes higher than the third quarter of 2025 and slightly improved sequentially from the second quarter. Boise Cascade is guiding third-quarter total company Adjusted EBITDA of about $82 million to $114 million and continues to stress inventory and production alignment with end-market signals.
Broader building products still echo the same disciplined theme. Simpson Manufacturing updated consolidated operating margin guidance to 19.7% to 20.5% for 2026, including a projected land-sale gain. Carlisle now expects mid-single-digit revenue growth with adjusted EBITDA margins flat. Patrick Industries is taking a prudent view of the balance of the year, emphasizing cost structure, customer closeness, organic initiatives, and M&A rather than a near-term market rebound.
Timber and real estate remain comparatively steady. Rayonier expects Southern harvest volumes of 12.2 to 12.5 million tons for the year, including 3.1 to 3.3 million tons in the third quarter, with sawtimber and pulpwood prices relatively stable versus the second quarter. Northwest harvest volumes are targeted at 2.0 to 2.2 million tons for the year and about 600,000 tons in the third quarter, with modestly higher third-quarter sawtimber prices and full-year Northwest log pricing above standalone prior-year levels. Full-year Real Estate Adjusted EBITDA is still expected at $180 million to $200 million. Weyerhaeuser expects third-quarter timberlands results slightly higher than the second quarter, with moderately higher West harvest volumes and higher South harvest volumes. Full-year Strategic Land Solutions Adjusted EBITDA was raised to about $450 million, though third-quarter real estate results are expected to be lower than the second quarter because of timing and mix.
Key factors to monitor into the second half: mortgage-rate stability around the current 6.76% level, oil and transportation costs, tariff and duty developments, labor and logistics constraints, and whether repair and remodel holds up better than current company assumptions. Price support in lumber has improved in places because supply is tighter, not because housing demand has clearly turned.
In summary for 2026 after the second quarter: most guidance now assumes softer housing and mixed repair activity, with only selective strength in specialties such as decking and parts of siding. Supply rationalization and cost control remain the main supports under the market. Long-term housing and wood-products fundamentals are still intact, but the near-term story is discipline, not acceleration.
