The dimensional tolerances for glulam are regulated by en 14080.
Glulam roof section.
Glue laminated beams glulam general.
The tables include values for section properties and capacities and allowable loads for simple span and cantilevered beams.
The glulam production process uses adhesive that complies with ss en 301 both for the finger jointing of individual laminates and to bond the laminates.
Glulam specification guide the following is a guide for preparing specifications for structural glued laminated timber used for bending members such as purlins.
Glued laminated timber is a versatile engineered wood that is frequently specified for its strength beauty and reliability.
Glulam allows a high degree of prefabrication and long structural spans where necessary but is equally effective for shorter spans.
Covered ceilings and roof beams.
While the details in this technical note address serviceability concerns associated with glulam connection detailing.
Glulam roof beams if the proposed design of your roof is not achievable using a conventional truss design then sydenhams can incorporate glulam laminated beams to provide support intermediately or as a design statement the beams can be left exposed to provide maximum impact.
Its thermal properties help prevent cold bridging.
The reference moisture content is 12.
Glulam connection details.
Table specifications are provided with each table indicating conditions and assumptions used to calculate the loads.
Glulam beams laid on their flat and used as floor or roof panels are known as glt panels see glue laminated timber panels.
A glue laminated timber is an engineered wood product meaning it is made from wood but is machined and assembled to precise specifications to create a predictable dimensionally stable building material.
Tolerances and the natural shrinking and swelling behaviour or timber may result in dimensional deviation of the cross section.
When using it outdoors glulam should be protected under a roof like other load bearing timber.
Other common engineered wood products include plywood oriented strandboard osb and laminated veneer lumber lvl.
Reviewing the examples with these principles in mind will enable the designer to more easily detail proper connections.
Discussed in the preceding section.
These tables are provided as a guideline.
Glulam can generally be used for the interior and the exterior.
