Building materials reference

Building Materials & Systems Encyclopedia

An educational reference to the materials, product formats and system components a building is made from — what each one is, what its behaviour depends on, what to ask about it and what documentation to request.

Every entry is written on one principle: suitability is a property of the complete assembly, not of the material on its own. It depends on the substrate, the exposure, the installation method, the manufacturer's documentation, local requirements and qualified professional review. Nothing here is a specification, a compliance determination or a recommendation.

How this differs from the Materials guides

Materials Library — this section

Reference entries about a specific material, product format or system component. Answers “what is this, and what does it depend on?”

Materials guides

Planning guides, room-by-room application guidance and neutral A-vs-B comparisons. Answers “how do I choose between these?”

Browse by family

Material families

Twelve categories, grouped into the three broad jobs materials do in a building.

Structure and base materials

What a building is built from and what other layers are fixed back to — concrete, masonry, timber and metals. · 54 entries

Envelope and protection

The layers that separate inside from outside and control heat, water, air and weather. · 50 entries

Interior surfaces and finishes

The materials people see, walk on and touch — floors, wall finishes, tile and stone, glass and glazing. · 46 entries

Browse by role

By the role a material plays

The same entries seen through what they do in an assembly. A material can appear under more than one role, because it genuinely plays more than one.

Browse by application

By part of a building

Where each material is commonly met. An orientation aid — never a statement that an entry suits a given building.

Selected entries

One from each family

A balanced starting point across the whole library — a sample, not a ranking.

Concrete & CementReady-mixed concreteConcrete batched at a plant and delivered wet by mixer truck, taking its shape from formwork and its surface from work done on site.Masonry & BlocksClay facing brickFired clay units chosen mainly for the look of the finished wall face, bedded in mortar and used where the brickwork itself is the visible external surface.Timber & WoodPlywoodPanel built from thin wood veneers bonded with the grain of each layer running across the last, which is where its stability and striped edge come from.MetalsStructural steelHot-rolled steel beams, columns and hollow sections used for primary structure, fabricated off site and connected on site by bolting or welding.InsulationMineral wool insulationFibrous insulation spun from melted rock and mineral feedstock, supplied as rolls, semi-rigid batts, rigid slabs and loose fill for walls, roofs, floors and partitions.RoofingNatural slate roofingNatural slate is a quarried metamorphic rock split into thin sheets and laid in courses, and this entry separates the stone itself from the manufactured boards that imitate its format.Exterior CladdingFibre cement claddingA cement, mineral filler and fibre board supplied as planks or flat sheets, normally hung on battens or rails over a ventilated cavity rather than fixed flat to the wall.Sealants & MembranesSilicone sealantA flexible cured-rubber jointing sealant associated with sanitaryware, glazing and wet junctions, water-tolerant but in most grades not paintable.Flooring MaterialsEngineered wood flooringA genuine hardwood wear layer bonded over a cross-bonded core, giving a real timber surface on a base that is dimensionally more settled than solid boards.Wall Finishes & LiningsPlasterboardA factory-made lining board with a gypsum core faced in paper, fixed to studs or bonded to masonry to form a flat internal surface ready for decoration.Tiles & StonePorcelain tileA fired clay tile pressed from a fine body at high temperature, generally far less absorbent than ordinary ceramic, and used on floors, walls and external surfaces.Glass & GlazingInsulated glass unitA factory-sealed assembly of panes, spacer and cavity in which the perimeter seal is the part that ages, and misting between panes signals unit replacement rather than repair.

Where to go next

This library explains what materials are. These sections help with choosing, planning and preparing.

What this library is not

  • It is not a marketplace, a supplier directory or a brand comparison. No product, manufacturer, supplier or installer is named, rated, ranked or recommended anywhere in it.
  • It is not a specification service or an engineering database. There are no calculations, no performance values, no classes, no grades and no specification tables.
  • It carries no prices, no cost comparisons, no service-life figures and no claims about energy, acoustic or fire performance.
  • It does not determine whether a material complies with any requirement, is structurally adequate, or is permitted in any jurisdiction. Those are matters for qualified professionals and the relevant authority.
  • It does not replace the manufacturer's own technical documentation for the specific product being proposed.
