| 01 | | THE FAILURE MODE |
| |
| The market that sells windows does not reach that stock. Windows are replaced when a house is built, sold or remodelled, which is a transaction cycle rather than a performance cycle. JELD-WEN told investors in August that it continues to expect the North American windows and doors market to decline by low to mid single digits in 2026 [3]. |
| The two remedies differ by an order of magnitude in cost. DOE describes storm window installation as one of the most cost-effective solutions for upgrading energy inefficient existing windows, costing a fraction of replacement windows, and states that installing a low-e storm window over a single pane window can lower a utility bill as much as replacing that window with a new energy code-level unit [2]. |
| What that is worth in dollars stays modest. DOE puts the saving at 10 to 30 percent of heating and cooling costs, or $100 to $300 a year against a $1,000 annual heating and cooling bill [2]. The measure scales with the bill, so it does least where energy is cheapest. |

| 02 | | YOUR END / THEIR END |
| |
YOUR END HOUSEHOLD The household response here is the storm window rather than the replacement window. DOE's own figures give the return: 10 to 30 percent off heating and cooling cost, $100 to $300 a year on a $1,000 bill, with exterior units fitting standard double-hung openings and taking 20 to 30 minutes each to install [2]. The low-e premium over a plain storm panel is about 10 percent and is cost-effective across every climate zone [1]. The cost is published as a ratio rather than a ticket, which is itself the limitation: DOE prices the measure against replacement windows, not in dollars per opening, so the quote is local. It is also an addition rather than a repair. The storm panel sits over the existing assembly and does nothing about a failed frame or sash, outward-swinging windows require interior panels instead of exterior ones [2], and the saving applies to the heating and cooling share of the bill rather than the whole of it.

THEIR END COMPANY-REPORTED JELD-WEN Holding (NYSE: JELD) manufactures and distributes interior and exterior doors and windows into the new construction and repair and remodelling markets [3]. North America net revenues were $528.5 million in the quarter ended 27 June 2026, down 4.9 percent year over year, driven by a 5 percent decline in volume and mix on weakened market demand, while North America adjusted EBITDA rose 17.1 percent to $40.7 million [3]. The first quarter had been weaker still, with consolidated net revenues of $722.1 million, down 6.9 percent on a 10 percent decline in volume and mix [4]. The counterweight is where the improvement came from. Segment profit rose on productivity and cost while volumes fell, and the company reported a net loss from continuing operations of $31.5 million for the quarter [3]. Ninety million underperforming openings are not a demand signal for this business; housing turnover is. POSITION / CAPACITY / RISK |

| 03 | | THE FILING |
| |
| JELD-WEN's second-quarter release, furnished on 3 August 2026, raised the low end of full-year 2026 revenue guidance to a range of $3.1 billion to $3.2 billion from $3.05 billion to $3.2 billion, and narrowed the expected core revenue decline to 2 to 5 percent from 3 to 6 percent [3]. The guidance moved on service and cost rather than on units. |
| |
| 04 | | THE TWO DECISIONS |
| |
| The household decision is a measure DOE prices as a fraction of replacement cost and values at $100 to $300 a year, which makes it one of the few efficiency purchases that pays back inside a normal ownership period and one of the smallest in absolute dollars. The exposure decision is a window manufacturer whose volumes are set by housing turnover and whose recent profit improvement came from cost rather than demand. The premise weakens materially if replacement window prices fall far enough to close the gap DOE describes, or if the single-pane share of the housing stock turns over fast enough that the 90 million figure stops describing the installed base. |

Reports Pacific Northwest National Laboratory findings: low-e storm windows can reduce heating and cooling costs by as much as 25% over a home's original single-pane or poor performing double-pane windows; the low-e coating can improve overall energy savings by 10-15% over standard storm windows without the coating; low-e storm windows cost about 10% more than standard storm windows, an additional expense confirmed cost-effective in all climate zones and with all types of windows; PNNL estimates more than 90 million U.S. homes with single-pane or poor performing double-pane windows would significantly benefit from the addition of low-e storm windows.

Storm window installation is one of the most cost-effective solutions for upgrading energy inefficient existing windows and costs a fraction of replacement windows; installing a low-emissivity storm window over a single pane window can lower a utility bill as much as replacing the window with a new energy code-level window; on average low-e storm windows can save 10%-30% in heating and cooling costs, equating to $100-$300 in annual savings assuming a $1,000 annual heating and cooling bill; installation takes 20-30 minutes per window; exterior storm windows fit all standard double-hung windows, while outward-swinging windows require interior storm windows.
