Glulam is glued laminated timber, also abbreviated as glulam, is a type of structural engineered wood timber product constituted by layers of dimensional lumber bonded together with durable, moisture-resistant structural adhesives. In US, the material made of wood providing the laminations is termed laminating stock.

By laminating a number of smaller pieces of glulam lumber, a single large, strong, structural member is manufactured from smaller pieces. These structural members are used as vertical columns, horizontal beams, and arches, header, girder, rafter, purlin and ridge beam in wood frame house.

Glulam optimizes the structural values of wood. Because of their composition, large glulam members can be manufactured from a variety of smaller trees harvested from second-growth forests and plantations.

Typical Glulam beam widths used in residential construction include: 3-1/8, 3-1/2, 5-1/8, 5-1/2, and 6-3/4 inches. For non-residential applications, where long spans, unusually heavy loads, or other circumstances control design, custom members are typically specified.

**What is Glulam Beam**

Glulam beam is engineered wood products manufactured by through the union of individual smaller pieces of lumber with special types of industrial adhesives usually Melamine or Polyurethane resin adhesives.

Glulam is a stress-rated engineered wood beam composed of wood laminations, or “lams”, that are bonded together with durable, moisture-resistant adhesives. The grain of the laminations runs parallel with the length of the member. Glulam is versatile, ranging from simple, straight beams to complex, curved members. Glulam beam uese as premium, architectural, industrial, or framing.

Its construction offers superior strength and stiffness over dimensional lumber. This type of beams is highly durable and moisture resistant, capable of generating large pieces and unique shapes.

What sizes Glulam beam comes in?Typically, sizes of Glulam beam is represented by their width and depth. Depth of Glulam beam are range from 7 1/4 inches (184mm) to 23 7/8 inches (606mm). Width of Glulam beam are range from 3-1/8″, 3-1/2″, 5-1/8″, 5-1/2″, 6-3/4 inches and 7 inches.

**Depth of Glulam beam**:- Glulam beam depth are typically are 7 1/4 inches (184mm), 9 inches, 9 1/4 inches (235mm), 9 1/2 inches (241mm), 11 1/4 inches (286mm), 11 7/8 inches (302mm), 14 inches (356mm), 16 inches (406mm), 18 inches (457mm), 18 3/4 inches (476mm), 20 inches (508mm) and 23 7/8 inches (606mm).

**Width of Glulam beam:-** typical stock beam widths used in residential construction include :- 3-1/8, 3-1/2, 5-1/8, 5-1/2, 6-3/4 inches and 7 inches. For non-residential applications, where long spans, unusually heavy loads, or other circumstances control design, custom members are typically specified.

**Glulam beam size calculator**

Glulam beam size calculator: To calculate the size of Glulam beam, convert the span length in feet to inches by multiplying with 12, divide the total span length in inches by 20 to get depth of Glulam beam. Width is 1/3 to 1/4 of the depth of Glulam beam.

Formula to calculate Depth of the Glulam beam = Span in inches/ 20. Width of the Glulam beam = Depth of beam/ 3. For example: if span is 20 feet, then depth of glulam beam = (20 × 12)/20 = 12″, rounding as 12″ and width = 12/3 = 4″, thus, you would need 5-1/2″ × 12″ size of glulam beam to span 20 feet.

**Glulam beam span calculator**

Glulam beam span calculator: To calculate the span length of Glulam beam, by using thumb rule, multiply the depth of beam in inches by 20 to get total span length in inches, divide the span length in inches by 12, resulting figure is span of glulam beam in feet.

**● How much topsoil do you need per square foot**

**● How much does a 2 cubic foot bag of mulch weigh**

**● How much does a cubic foot of gravel weigh**

**● How many bundles of shingles do i need for a 2000 square foot house**

Formula to calculate span length of glulam beam in feet = (Depth of beam in inches × 20)/ 12. For example: how far can you span 5-1/2″ × 16″ size of glulam beam, span of glulam beam = (16″ × 20) / 12 = 320/ 12 = 27 feet, thus, 5-1/2″ × 16″ size of glulam beam can allow to span 27 feet approx.

**Conclusions:-**

Typically, sizes of Glulam beam is represented by their width and depth. Depth of Glulam beam are range from 7 1/4 inches (184mm) to 23 7/8 inches (606mm). Width of Glulam beam are range from 3-1/8″, 3-1/2″, 5-1/8″, 5-1/2″, 6-3/4 inches and 7 inches.
