Installed Bldg Prods — Business Overview
What does IBP do?
Installed Building Products (IBP) is primarily a contractor that installs insulation and other building products for homebuilders and commercial construction firms across the United States. Founded in Columbus, Ohio in 1977, IBP has grown through more than 200 acquisitions into one of the largest insulation installers in the country, operating roughly 250 branch locations across all 48 continental states and the District of Columbia. The company employs approximately 10,400 people.
IBP operates across three segments:
| Segment | What it does | Share of net revenue (2025) |
|---|---|---|
| Installation | Installs insulation and other building products (garage doors, rain gutters, shower doors, window blinds, fireproofing, etc.) at job sites | ~93% |
| Distribution | Wholesales insulation and gutter supplies to independent contractors through regional distribution centers | ~5% |
| Manufacturing | Produces cellulose insulation and specialty industrial fibers at two plants in Ohio and North Carolina | ~2% |
Within the Installation segment, insulation alone made up 58% of IBP's $3.0 billion in net revenue for 2025. Other notable product lines include shower doors/closet shelving/mirrors (7%), garage doors (6%), waterproofing (5%), rain gutters (4%), fire-stopping/fireproofing (4%), and window blinds (3%).
How does IBP make money?
IBP's core revenue model is service-based: it charges builders and contractors for physically installing products at construction sites. Rather than manufacturing or retailing products, IBP buys materials directly from manufacturers and provides the labor, scheduling, logistics, and quality inspection needed to complete each installation phase. Most installers are paid per completed job, which keeps labor costs variable with revenue.
A key structural advantage in this model is that IBP cuts out the middleman. In a typical building products supply chain, materials flow from manufacturer to distributor to retailer before reaching an installer. IBP buys directly from manufacturers, which reduces its cost basis and gives it better pricing leverage — an advantage smaller local competitors cannot easily replicate. Its top three suppliers combined accounted for about 35% of all material purchases in 2025.
What market does IBP operate in?
IBP's fortunes are closely tied to the U.S. residential new construction market, which is currently under pressure. Housing starts fell to 1.36 million in 2025 (down from 1.61 million in 2021), with single-family starts declining 6.9% year-over-year. Fannie Mae projects a further 3.7% decline to approximately 1.31 million starts in 2026, driven by elevated mortgage rates and affordability concerns. IBP's largest customers are publicly traded homebuilders, and approximately 17% of its installation revenue comes from commercial construction — a segment that provides some diversification and tends to offer more revenue visibility due to longer project timelines.
Secular tailwinds around energy efficiency support long-term demand for insulation. The U.S. Department of Energy estimates that over half of energy use in the average American home goes to heating and cooling, largely because of inadequate insulation. Tightening building codes and energy efficiency standards push new construction toward better-insulated buildings, which structurally supports IBP's primary product line over time.
Who are IBP's main competitors?
The building products installation industry is highly fragmented, and IBP's national scale is its primary competitive edge. The company claims the number one or two market position for new single-family insulation installation in more than half of its operating markets. Competitors include one other large national installer, several large regional contractors, and a very large number of small local operators. The non-insulation product markets IBP serves are described as even more fragmented than the insulation market.
IBP's claimed competitive advantages center on scale, local relationships, and a diversified product mix. Buying directly from the four major fiberglass insulation manufacturers — Owens Corning, Knauf Insulation, CertainTeed, and Johns Manville — across more than two decades of relationships gives IBP preferred pricing terms that smaller competitors struggle to match. Its top 10 customers represent only about 14% of net revenue, and even its single largest customer (roughly 4% of revenue) is served independently by 96 different IBP branches, suggesting the business is not dangerously concentrated with any one buyer.
Where does IBP operate?
IBP operates exclusively within the continental United States, with no international exposure. Its approximately 250 branch locations span all 48 continental states and the District of Columbia, giving it genuine national coverage rather than regional concentration. Distribution operations serve the Midwest, Mountain West, Northeast, and Mid-Atlantic regions specifically. Manufacturing facilities are located in Bucyrus, Ohio and Ronda, North Carolina.
There is no meaningful geopolitical risk from international operations, but the business does have some domestic regional seasonality. Branches in states with harsh winters experience slower activity in the first quarter of each calendar year. The company generates higher revenue in the second half of the year as builders complete homes that went under contract during the spring selling season.
