Glulam brace with plates used for connections Glulam frame of a roof structure. Glued laminated timber, commonly referred to as glulam, is a type of structural engineered wood product constituted by layers of dimensional lumber bonded together with durable, moisture-resistant structural adhesives so that all of the grain runs parallel to the longitudinal axis.
Cement bonded wood fiber materials can be classified as low density, medium density and high density. The density of the material will determine to a large extent, the various properties of the end product. Other factors determining the overall performance of a cement bonded wood fiber material are: Wood particle type; Wood particle gradation
Wood glue is an adhesive used to tightly bond pieces of wood together. Many substances have been used as glues. Many substances have been used as glues. Traditionally animal proteins like casein from milk or collagen from animal hides and bones were boiled down to make early glues.
Engineered wood products are used in a variety of applications, from home construction to commercial buildings to industrial products. [3] The products can be used for joists and beams that replace steel in many building projects. [4] The term mass timber describes a group of building materials that can replace concrete assemblies.

In this way the log is peeled into sheets of veneer, which are then cut to the desired oversize dimensions, to allow it to shrink (depending on wood species) when dried. The sheets are then patched, graded, glued together and then baked in a press at a temperature of at least 140 °C (284 °F), and at a pressure of up to 1.9 MPa (280 psi) (but ...
Lath and plaster is a building process used to finish mainly interior dividing walls and ceilings. It consists of narrow strips of wood which are nailed horizontally across the wall studs or ceiling joists and then coated in plaster. The technique derives from an earlier, more primitive process called wattle and daub. [1]

A cement board is a combination of cement and reinforcing fibers formed into sheets, of varying thickness that are typically used as a tile backing board. [1] Cement board can be nailed or screwed to wood or steel studs to create a substrate for vertical tile and attached horizontally to plywood for tile floors, kitchen counters and backsplashes.
