Construction Materials Guide

Choosing the right construction materials affects nearly every part of a building.

Materials influence:

• Structural strength
• Energy efficiency
• Water resistance
• Fire performance
• Indoor air quality
• Maintenance
• Appearance
• Construction speed
• Project cost
• Expected service life

Homeowners and contractors now have more choices than traditional wood, steel, concrete, brick, and drywall. Modern projects may also use natural building materials, recycled products, low-VOC finishes, advanced insulation, flexible membranes, engineered wood, reclaimed materials, and other alternative construction materials.

However, there is no single material that is best for every building.

The correct choice depends on the project's:

• Location
• Climate
• Soil
• Building type
• Structural requirements
• Moisture exposure
• Fire requirements
• Budget
• Desired appearance
• Maintenance plan
• Expected service life

A low-cost material can become expensive when it requires frequent repair. A natural material may fail if it is installed in a wet location without adequate protection. An energy-efficient building material may underperform when gaps, air leakage, or poor flashing are present.

The most successful buildings use compatible materials as part of a complete system.

Water management is especially important. Water intrusion can damage concrete, reinforcing steel, mortar, insulation, wood framing, drywall, flooring, and interior finishes. Protecting these materials can help extend the building's useful life and reduce unnecessary replacement.

What Are Construction Materials?

Construction materials are the products and substances used to build, repair, finish, or protect a structure.

They may be used for:

• Foundations
• Structural frames
• Walls
• Roofs
• Floors
• Insulation
• Windows
• Doors
• Exterior finishes
• Interior finishes
• Waterproofing
• Mechanical systems
• Landscaping

Construction materials may be natural, manufactured, recycled, reclaimed, renewable, or combined into engineered products.

A complete building may contain hundreds of different materials, including fasteners, sealants, membranes, coatings, insulation, wiring, pipes, finishes, and structural components.

Most Used Building Materials

The most used building materials vary by region and building type, but several categories appear in projects around the world.

Concrete

Concrete is used for:

• Foundations
• Slabs
• Walls
• Columns
• Beams
• Bridges
• Parking structures
• Retaining walls
• Infrastructure

Concrete offers:

• High compressive strength
• Fire resistance
• Versatility
• Thermal mass
• Long service life when properly designed
• Compatibility with reinforcement

Concrete is porous, so drainage, crack control, joint treatment, curing, and waterproofing may be necessary.

Steel

Steel is used in:

• Structural frames
• Reinforcing bars
• Roofing
• Wall studs
• Fasteners
• Stairs
• Railings
• Exterior panels

Steel offers:

• High strength
• Predictable engineering properties
• Long spans
• Recyclability
• Prefabrication opportunities

Steel may corrode when exposed to moisture and certain chemicals. It also transfers heat easily, which can create thermal bridges.

Wood

Wood is used for:

• House framing
• Roof structures
• Flooring
• Cabinets
• Doors
• Cladding
• Furniture
• Interior finishes

Wood is relatively light and easy to work with. Responsibly managed timber can also be renewable.

Wood must be protected from:

• Moisture
• Termites
• Rot
• Fire
• Prolonged soil contact

Brick and Masonry

Brick and concrete masonry units may be used for:

• Exterior walls
• Interior partitions
• Structural walls
• Fire separations
• Landscaping
• Decorative features

Masonry can be durable, but mortar joints, flashing, drainage, and water exposure must be managed carefully.

Glass

Glass is used for:

• Interior partitions
• Skylights
• Decorative features

Modern high-performance glass may include insulated units, coatings, tinting, and laminated layers.

Large glass areas should be evaluated for heat gain, heat loss, glare, impact, and water leakage.

Gypsum Drywall

Drywall is commonly used for interior walls and ceilings.

It provides:

• Smooth finishes
• Fire-rated assemblies
• Easy installation
• Access for repairs
• Multiple finish options

Standard drywall is vulnerable to prolonged water exposure. Moisture-resistant products may be appropriate in certain areas, but they do not replace waterproofing.

Building Materials for Homes

The major building materials for homes generally fall into several systems.

Foundation Materials

Possible foundation materials include:

• Reinforced concrete
• Concrete masonry
• Stone
• Insulated concrete forms
• Precast concrete

The foundation must support the home while managing soil pressure, groundwater, drainage, vapor, and structural movement.

Framing Materials

Common framing options include:

• Dimensional lumber

Environmentally friendly building materials are selected with consideration for sourcing, manufacturing, transportation, durability, maintenance, and disposal.

Possible examples include:

• Reclaimed wood
• Responsibly sourced timber
• Recycled steel
• Recycled aluminum
• Reclaimed brick
• Recycled glass
• Cellulose insulation
• Cork
• Bamboo
• Hemp-based products
• Recycled-plastic products
• Efficient concrete mixtures
• Durable mineral finishes
• Salvaged fixtures

A material is not environmentally friendly only because it is natural or recycled.

Important questions include:

• How was it sourced?
• How much processing was required?
• How far was it transported?
• How long will it last?
• Can it be repaired?
• What maintenance does it require?
• Can it be reused or recycled?

The most environmentally friendly building materials are usually those that safely meet the project's requirements while creating the lowest reasonable life-cycle impact.

Natural Building Materials

Natural building materials come primarily from resources found in nature.

Examples include:

• Timber
• Stone
• Earth
• Clay
• Straw
• Bamboo
• Cork
• Hemp
• Lime
• Sand
• Thatch
• Natural fibers

Natural materials may provide distinctive textures, renewable sourcing, thermal mass, insulation, or local availability.

However, they may require special protection from:

• Rain
• Groundwater
• Humidity
• Fire
• Insects
• Mold
• Structural movement

Natural does not automatically mean nontoxic, durable, or appropriate for every application.

Renewable Building Materials

Renewable building materials come from resources that can regenerate within a reasonable period when managed responsibly.

Examples may include:

• Timber
• Bamboo
• Cork
• Hemp
• Straw
• Agricultural fibers
• Wool
• Plant-based products

The sustainability of a renewable product also depends on:

• Farming or forestry practices
• Manufacturing
• Adhesives
• Finishes
• Transportation
• Service life
• Disposal

A renewable product that must be replaced frequently may use more resources over time than a durable material with a longer service life.

Alternative Building Materials

Alternative building materials are products or systems used instead of, or alongside, common conventional materials.

Examples include:

• Rammed earth
• Adobe
• Compressed earth blocks
• Straw-bale walls
• Hemp-lime
• Earthbag construction
• Cordwood
• Recycled-plastic lumber
• Shipping-container systems
• Mycelium panels
• Structural insulated panels
• Insulated concrete forms
• Recycled composite panels
• 3D-printed materials

Alternative building materials for homes can provide useful options, but local approval, engineering, moisture resistance, fire performance, and labor availability should be investigated before construction begins.

Alternative House Building Materials

Alternative house building materials may be used for walls, insulation, framing, roofing, flooring, or finishes.

Examples include:

• Straw bales for insulated walls
• Hemp-lime for wall infill
• Rammed earth for thermal-mass walls
• Bamboo for flooring and panels
• Reclaimed timber for framing or finishes
• Cork for insulation and flooring
• Recycled plastic for decking
• Earth blocks for selected wall systems

Many alternative systems still rely on conventional concrete foundations and structural connections.

Energy-Efficient Building Materials

Energy-efficient building materials help reduce heating, cooling, or lighting demand.

Examples include:

• High-performance insulation
• Structural insulated panels
• Insulated concrete forms
• High-performance windows
• Exterior continuous insulation
• Air-barrier membranes
• Reflective roofing
• Insulated doors
• Thermal-break products
• Phase-change materials

The most energy-efficient building materials will not perform as intended without correct installation.

Energy performance depends on:

• Insulation continuity
• Air sealing
• Window placement
• Thermal bridges
• Moisture control
• Building orientation
• Shading
• Climate

Insulation Materials

Common insulation products include:

• Cellulose
• Fiberglass
• Mineral wool
• Foam boards
• Spray foam
• Cork
• Wood fiber
• Hemp fiber
• Recycled denim

Each has different characteristics for:

• Thermal resistance
• Fire
• Moisture
• Air control
• Cost
• Installation
• Environmental impact

Energy-Efficient Construction Materials

Energy-efficient construction materials should be coordinated into a complete building envelope.

A successful envelope controls:

• Heat
• Air
• Rain
• Groundwater
• Water vapor
• Sunlight

A high-performance window placed in a poorly insulated wall may not produce the expected energy savings.

Cost-Effective Building Materials

Cost-effective building materials provide dependable performance at a reasonable total cost.

The lowest purchase price does not always produce the lowest project cost.

Total cost may include:

• Purchase

A discounted material that is incorrect for the application may cost more to remove and replace.

Technical construction products should not be selected on price alone.

Non-Toxic and Healthy Building Materials

Healthy building materials are selected to support safer indoor environments.

Possible concerns include:

• Volatile organic compounds
• Formaldehyde
• Solvents
• Plasticizers
• Dust
• Fibers
• Heavy metals
• Mold
• Moisture
• Cleaning chemicals

Possible lower-emission options may include:

• Low-VOC paint
• Mineral-based finishes
• Solid wood with appropriate coatings
• Clearly documented insulation
• Low-emission adhesives
• Cork
• Clay plaster
• Lime plaster
• Certain tile and stone products

The term "non-toxic building materials" can be misleading because exposure depends on the substance, amount, installation, ventilation, and use.

Customers should request specific product documentation instead of relying only on broad claims.

Low-VOC Building Materials

Low-VOC building materials may include:

• Paint
• Coatings
• Adhesives
• Sealants
• Flooring
• Cabinets
• Composite wood
• Insulation

Low-VOC does not necessarily mean zero emissions. The complete installed system should be evaluated, including primers, adhesives, cleaners, and maintenance products.

Organic and Biodegradable Building Materials

Organic building materials may include products derived from plants or animals, such as:

• Timber
• Bamboo
• Cork
• Straw
• Hemp
• Wool
• Natural fibers

Biodegradable building materials can break down through natural processes under suitable conditions.

Potential examples include:

• Untreated wood
• Straw
• Hemp fiber
• Cork
• Natural-fiber products
• Mycelium-based materials

Biodegradability can be beneficial at the end of a product's life, but it can also create durability concerns during use.

A building material should not biodegrade while it is still protecting or supporting the structure.

Moisture protection, fire performance, insects, and service life remain important.

Recyclable Construction Materials

Recyclable construction materials may be processed after use and turned into new products.

Examples include:

• Steel
• Aluminum
• Copper
• Glass
• Concrete
• Brick
• Asphalt
• Gypsum
• Selected plastics
• Certain insulation products

Actual recyclability depends on:

• Local recycling facilities
• Material contamination
• Product coatings
• Fasteners
• Adhesives
• Ability to separate materials
• Market demand

A material may be recyclable in theory but difficult to recover when it is permanently bonded to other materials.

Designing buildings for disassembly can improve future recycling.

Carbon-Neutral Building Materials

The term carbon-neutral building materials is used for products that claim to balance or eliminate certain greenhouse-gas emissions associated with production or use.

These claims should be examined carefully.

Ask:

• Which life-cycle stages are included?
• Are transportation and installation included?
• Are offsets being used?
• Is the claim independently verified?
• Does it apply to the complete product?
• How long will the product last?
• What happens at the end of its life?

Very few materials have no associated emissions.

A more useful approach may be to compare documented life-cycle impacts while also considering durability, performance, and replacement.

Flexible Building Materials

Flexible building materials can bend, move, stretch, or accommodate changes without immediate failure.

Examples may include:

• Waterproofing membranes
• Sealants
• Expansion-joint systems
• Flexible insulation
• Resilient flooring
• Rubber products
• Certain composite panels
• Flexible flashing

These materials may be useful at:

• Building joints
• Roof transitions
• Wall penetrations
• Movement locations
• Curved surfaces
• Irregular details

Flexibility does not mean unlimited movement. Every product has limits for temperature, stretching, compression, UV exposure, and chemical resistance.

Unique Building Materials and Innovation

Innovation in building materials continues to create new options for energy performance, waste reduction, strength, and design flexibility.

Unique building materials may include:

• Transparent wood products
• Mycelium panels
• Aerogel insulation
• Phase-change materials
• Self-healing concrete concepts
• Recycled-plastic blocks
• Carbon-storing products
• Bio-based composites
• 3D-printed cementitious materials
• Advanced mass timber
• Flexible solar materials
• Recycled-fiber panels

Innovative products should be evaluated for:

• Building-code approval
• Structural performance
• Fire testing
• Moisture resistance
• UV resistance
• Durability
• Repairability
• Installer availability
• Replacement availability
• Warranty
• Environmental documentation

New does not automatically mean better. A proven material with a long service life may be a more appropriate choice.

Most Durable Building Materials

The most durable building materials depend on the exposure and application.

Materials known for potentially long service lives include:

• Stone
• Properly designed concrete
• Brick
• Structural steel
• Copper
• Slate
• Clay tile
• Certain metal roofing
• Properly protected timber

Durability depends on more than the raw material.

It is affected by:

• Design
• Installation
• Moisture
• Chemicals
• Temperature
• Freeze-thaw cycles
• Sunlight
• Maintenance
• Structural movement

Concrete may last for many decades, but poor drainage and reinforcing-steel corrosion can shorten its service life. Wood may last for generations when kept dry but deteriorate quickly under constant moisture.

Waterproofing Construction Materials

Water damage can affect both conventional and alternative building materials.

Water may enter through:

• Roof leaks
• Foundation walls
• Concrete slabs
• Cracks
• Construction joints
• Windows
• Doors
• Balconies
• Plumbing
• Poor drainage

Moisture may damage:

• Concrete
• Reinforcing steel
• Mortar
• Wood
• Insulation
• Drywall
• Flooring
• Paint
• Equipment
• Interior finishes

Waterproofing should be treated as part of the building system rather than a decorative coating added at the end.

Concrete Waterproofing

Concrete contains capillary pores and may develop cracks, joints, or installation defects.

A complete water-management plan may include:

• Site grading
• Foundation drainage
• Vapor barriers
• Waterstops
• Crack treatment
• Joint sealants
• Exterior membranes
• Integral waterproofing
• Surface-applied products
• Roof drainage
• Maintenance
