Question

What is ‘Glulam’ and are the laminations normally vertical or horizontal?

Answer 1

GLULAM

It is a structural material manufactured by the union of individual wood segments.

When glued with industrial adhesives like melamine or polyurethane resin adhesives then this type of wood is highly durable and moisture resistant, capable of generating large pieces and unique shapes.

It is suitable for use on beams, pillars, ceilings, stairs, panels, cladding etc.

In Glulam the connections between different elements can be made with steel connectors.

Advantage of Glulam are-

(i) Unique dimensions

It has high load capacity and low weight, Glulam covers large areas with small components. It can cover sections of up to 100 meters without intermediate support.

(ii) Resistance

It can resist various chemicals and also resists transformations caused by moisture, such as deformations or torsions.

(iii)Flexibility:

The curved, arched and folded shapes are reproduced quite easily. Pieces don't necessarily need to follow the geometry of the tree trunk.

(iv)High fire resistance:

The structures made of glued laminated wood are safer than unprotected steel in fire. It is because a carbonized layer forms around the Glulam's core, decreasing oxygen consumption and retarding combustion.

.

Projects in which Glulam are used-

It is used for any type of construction from residential projects to industrial buildings.

It can even applied to buildings located in areas with specific climatic demands provided that a moisture protection treatment must be applied.

Laminations in Glulam-

Yes,the laminations in Glulam are normally vertical or horizontal.

Horizontal laminations are used for furniture and laminates are placed one after another horizontally.

Vertical lamination are more stable and normally opted for Glulam construction.

Both horizontal and vertical laminations are widely used for Glulam.
