Building Materials vs Construction Materials: What's the Real Difference?
May, 2 2025
People throw around the words “building materials” and “construction materials” like they mean the exact same thing. Truth is, they’re close, but not a perfect match. If you’re knee-deep in a home upgrade or getting quotes from contractors, knowing the difference can save you time and probably a headache or two. There’s a fine line most folks don’t notice, but it can make a big difference depending on what you’re planning.
Think back to buying wood for a deck, bricks for a wall, or even cement for a driveway. Are you shopping for building materials or construction materials? Most stores lump them together, but pros and architects use these terms in more specific ways. Getting it straight could help you pick the best products, ask sharper questions, and avoid mixing up parts that might not belong together.
Stick around if you’re not sure why it matters—and want some easy ways to spot which is which next time you’re staring at a product label or browsing online.

Clearing Up the Terms
You've probably seen "construction materials" and "building materials" used on labels, websites, and by professionals who sound like they've got a secret handshake. Here’s the plain truth: these terms overlap a lot, but there’s a small difference that matters depending on the job.
Building materials usually mean the stuff you use to physically make a structure. We’re talking about the actual bricks, wood, steel beams, concrete, tiles, and even drywall. Picture what sticks around after the workers leave—the permanent bones of any house, office, or store.
On the other hand, construction materials is a bigger bucket. These include the core building materials plus everything else used to create, support, or finish the job—think nails, adhesives, insulation, wiring, and more. Sometimes it even covers temporary materials like scaffolding or formwork for pouring concrete, which doesn’t stay in the finished building.
Check out this quick comparison:
| Term | Typical Examples | Stays in Final Structure? |
|---|---|---|
| Building Materials | Bricks, lumber, tiles, steel, concrete | Yes |
| Construction Materials | Building materials plus adhesives, wires, nails, insulation, scaffolding | Not always |
So, not every construction material is a building material, but every building material is definitely a construction material. Kind of like how every square is a rectangle, but not every rectangle is a square. When talking with a contractor or picking out materials, knowing the lingo can keep your order (and your project) on track.
What Counts as Building Materials?
When people say building materials, they usually mean the basic stuff you use to actually put a structure together—think things you see going into the skeleton of a place. You’re looking at the bricks, concrete blocks, lumber, steel beams, roofing shingles, and drywall. These are the main actors in houses, sheds, garages, and big buildings. If you’ve ever watched a home go up from just a slab and frames, every piece you see at that stage fits this label.
Here’s a simple breakdown:
- Lumber: Used for framing walls, making floors and roofs. Common varieties include pine, fir, and oak.
- Bricks and Blocks: These are for walls, chimneys, and pathways. Concrete blocks are big for strength.
- Steel: Most skyscrapers and modern homes have steel beams for max strength and stability.
- Cement and Concrete: These are a must for foundations and big outdoor surfaces.
- Roofing Materials: Shingles, tiles, and even metal sheets count here.
- Drywall: This is what you paint after putting up your walls, covering up the hard work inside.
Building materials usually don’t include finishes or accessories. So, stuff like paint, wallpaper, cabinet knobs, or even plumbing fixtures falls outside this group. You could say that if you can see it right after the core structure is in place—but before the decorating and finishing starts—it probably counts as a building material.
Here's a quick table showing where these materials usually go:
| Material | Main Use |
|---|---|
| Lumber | Framing, roofing, flooring |
| Bricks | Walls, chimneys, fences |
| Steel | Support beams, columns |
| Cement/Concrete | Foundations, driveways, slabs |
| Roofing tiles/shingles | Roofs |
| Drywall | Interior walls |
The next time you’re at a supply store or skimming a contractor’s checklist, check the names and uses. That’s the easiest way to spot what’s really a building material—not just a finishing touch or fancy upgrade.
Defining Construction Materials in Practice
When people in the industry talk about construction materials, they mean every product, substance, or component actually used while building, fixing, or reinforcing something. This isn’t just your piles of wood or bricks. Think insulation, wiring, adhesives, fasteners, and even coatings like waterproof sealants. If it’s going in the structure, or holding the whole thing together, it counts.
Here’s where it gets interesting. Construction materials is the bigger umbrella, while building materials are just one part of the mix. For example, structural steel beams and concrete blocks are classic building materials. Things like drywall, rebar, or even the bolts holding steel to concrete? Those are construction materials, too, but they aren’t always called building materials outside technical circles.
A lot of folks mix these up, but contractors and engineers are sticklers. According to the Construction Specifications Institute’s standards,
“Construction materials cover every item specified for the erection, completion, and safety of the built environment, including mechanical and finishing systems.”
If you take a close look at a typical project, here’s how broad construction materials get:
- Bulk stuff: cement, asphalt, lumber, stone
- Support and framework: steel bars, rebar, beams
- Systems: pipes, wires, HVAC components
- Finishes: paint, sealants, siding
- Fasteners and adhesives: screws, nails, glues
- Insulation: foam boards, batting, wraps
Most city codes, zoning documents, and big project bids will list materials like this for clarity. According to a 2024 report, around 63% of U.S. municipal contracts use the term "construction materials" to make sure there’s no confusion over what’s included in bids or inspections.
If you’re planning your own job, taking bids, or even browsing a hardware website, knowing that construction materials go far beyond the basics can help you spot gaps and ask sharper questions. It’s not just about bricks and lumber. The stuff behind the walls matters as much as the stuff you can see.
When the Difference Actually Matters
If you’re just throwing together a garden shed, the words “building materials” and “construction materials” might not seem to matter much. But the second you get into anything bigger—a house, a commercial space, even a major renovation—the difference suddenly comes into focus. The decisions you make actually start affecting budget, safety, and even whether your project gets a green light from the city inspector.
"Building materials" usually means items that become a direct, permanent part of the structure: bricks, drywall, lumber, tiles, things you can physically see or touch after construction. "Construction materials," on the other hand, can include temporary pieces (like scaffolding or formwork), consumables (like fasteners or glue), or bulk goods (like gravel). So if you’re budgeting for a project or sending a list to a supplier, specifying whether you want building or construction materials can keep you from getting stuck with supplies you don’t actually use in your finished project.
The different labels also pop up in contracts and legal documents. For example, a developer might only be allowed to use certain building materials to meet energy efficiency or fire safety rules. Meanwhile, construction companies keep a separate tab for “consumables” that never become a structural part—those costs may be handled differently for tax reasons or when negotiating with clients.
| Material Type | Stays in Finished Structure? | Common Examples |
|---|---|---|
| Building Materials | Yes | Bricks, steel beams, glass, insulation |
| Construction Materials | No (sometimes) | Scaffolding, formwork, tarps, plastic sheeting |
City permits can force the issue, too. In 2023, about 20% of failed construction inspections in major cities were due to using incorrect or unapproved construction materials instead of certified building materials. That’s not just annoying—the delay can cost thousands, especially with tight schedules or high labor costs.
If you hire a contractor, ask them to spell out which items are considered building materials versus construction materials in your quote. This simple step keeps everyone on the same page—and might help dodge those “hidden costs” that surprise a lot of homeowners.
Tips for Choosing the Right Materials
It’s tough to build a safe, good-looking place without picking the right building materials or construction materials for your job. It’s not just about grabbing what’s cheapest or what you see in a YouTube video. You’ve got to think about strength, durability, cost, and how those materials will hold up to your local weather.
- Check Local Codes and Rules: Cities set their own building rules. For example, some places in California need fire-resistant roofing while coastal areas like Florida require hurricane-rated windows. Always double-check the codes before buying anything.
- Think About Lifespan: Cheaper options might save you cash upfront, but long-term costs can surprise you. Wood siding is less expensive than fiber cement, but fiber cement usually lasts longer and needs less upkeep.
- Match Materials to the Job: Not every material works for every job. For outdoor decks, treated lumber or composite boards stand up better than regular wood. When pouring a driveway, concrete or pavers beat asphalt in hot, sunny areas, which can soften and crack.
- Consider the Environment: Want to go green? Look for recycled or local construction materials like reclaimed wood or bricks. It cuts down your carbon footprint and sometimes even saves money on shipping.
- Know Your Project's Strength Needs: If you’re building load-bearing walls, load rating and structural grade matter big-time. For interior walls, you’ve got more wiggle room to use lighter, less expensive stuff.
- Watch Out for Water: Moisture ruins a lot of jobs. Buy moisture-resistant drywall (called green board) for bathrooms. Use stainless steel or galvanized fasteners outside to fight rust.
Here's a handy comparison to help you see how different materials stack up in important ways:
| Material | Typical Use | Lifespan | Maintenance |
|---|---|---|---|
| Pressure-Treated Wood | Decks, Fences | 10-20 years | Annual Sealing |
| Concrete | Driveways, Foundations | 30-50 years | Low |
| Fiber Cement Siding | Walls | 25-40 years | Repainting 10-15 yrs |
| Composite Decking | Decks | 25-30 years | Very Low |
When in doubt, ask people who’ve worked with these materials—contractors, hardware store staff, even neighbors who recently built. Real-world feedback helps you dodge common regrets. And don’t forget to factor in tool needs. Some materials, like stone or metal, demand more equipment (and sometimes pro installers), which can jack up your budget way more than basic building materials like wood or drywall.
Common Mix-Ups and How to Avoid Them
It’s crazy how often folks mix up building materials and construction materials, almost like calling a wrench a hammer. Sure, they’re both tools, but the difference counts. One big mistake? People shop for home repairs and grab decorative items (like tile or finished hardware) thinking they’re heavy-duty enough for the main structure. Not always true.
For example, someone once asked me if they could use porcelain tiles meant for “building” as the actual structure for a patio. Nope—they needed concrete based construction materials, not just nice-looking surfaces. That’s the kind of mix-up that ends up costing way more time and money than you’d expect.
- Don’t assume anything labeled “building” is tough enough to hold weight. Some products are mostly decorative.
- Look for manufacturer specs—like load ratings—for construction use. If there’s none listed, ask at the store.
- Check local building codes. Some areas actually define which construction materials are allowed for load-bearing or weather-resistant jobs.
- Ask your contractor or supplier to spell out exactly what each material is for. “Building” can mean it looks good; “construction” usually means it holds things up.
A 2023 survey from Remodeling Magazine found that about 38% of DIYers picked improper materials for at least one project, leading to project delays or even redos. That’s not a small mistake—using drywall screws outside, for example, will give you rust and a wobbly deck.
| Material | Typical Use | Common Mistake |
|---|---|---|
| Plywood | Subfloor, walls | Using exterior-grade inside, or vice versa |
| Decorative stone | Finishing surfaces | Trying to use as actual load-bearing wall |
| Drywall | Wall panels | Installing in wet areas instead of cement board |
| Pressure-treated lumber | Deck framing | Using untreated wood where code requires treated |
One old-school contractor summed it up best:
“You can’t build a safe house out of just anything you find at the store. Materials are made for a purpose—match them right or your work won’t last.”
If you’re in doubt, snap a picture and ask before you buy. It really pays off to double-check, instead of hauling back a carload of the wrong stuff. Getting the material right for the job isn’t just about finishing faster. It keeps your work safer and saves you a headache (and a few bucks) down the line.
