Installing Windows and Doors in Glulam Frames
Although glulam is most frequently seen in exposed applications such as vaulted ceilings, it also lends itself to many commonly concealed framing projects – for instance glulam floor beams can often be fully or partially hidden within their respective floor joist cavities.
Glulam, or laminated wood, is an engineered product comprised of lumber lams bonded together with resilient moisture-resistant adhesives to form an engineered wood composite material. Commonly made out of softwood species like Douglas-fir and spruce-pine-fir, glulam can come in various sizes with four distinct appearance categories such as premium, architectural, industrial or framing for final assembly.

Glulam, or glue laminated timber, is an innovative construction material that has vastly broadened what architecturally possible with wood. Structurally speaking, glulam components consist of multiple lumber laminations bonded together using moisture-resistant adhesives; their positions are determined based on stress-rated performance characteristics in order to absorb stress proportionately and prolong component lifespan – creating long span structures without incurring steel fabrication costs or time costs for fabrication processes.
Glulam is often utilized for decorative applications like vaulted ceilings and designs with open spaces, as well as its hidden role in residential and light commercial buildings’ floor beams and roof trusses. Available in four appearance grades – framing, industrial, architectural, and premium – glulam offers both strength and beauty for an array of design solutions.
When combined with additional insulation, glulam can provide energy-efficient thermal properties that prevent thermal bridging – leading to significant savings on heating and cooling bills as well as lessening foundational loads for buildings.
Glulam offers an environmentally-friendly and cost-effective option that stands apart from conventional steel or concrete construction methods. Furthermore, this natural alternative can be fabricated offsite to reduce build schedules and site working hours significantly while its lightweight composition reduces transportation costs as well as its impact on the environment. Furthermore, one crew can install it without the need for separate steelwork crews; providing project owners and contractors alike a more streamlined construction process and schedule.
Preparation of the Frame
Glulam production begins by fabricating lamellas (small sheets of wood) from various species that are then glued together into structural members, producing strong and stable members that boast significantly greater strength than steel. Furthermore, this material requires significantly less energy to produce than both concrete and steel production processes and its use of wood allows it to come from sustainably managed forests ensuring its source and source are responsible.
Engineering glulam into any structure offers architects and designers endless creative options. It is often specified for exposed applications like vaulted ceilings in homes, schools and office buildings; vaulted ceilings as well as designs with open areas like living rooms. Also glulam is often specified due to both its aesthetic qualities as well as strength. There are four appearance grades: framing, industrial, architectural and premium; this material comes complete with paints, stains and veneers for finishing applications.
Glulam’s lightweight nature makes it an attractive construction material, as it speeds up build schedules and minimizes its environmental impact. Furthermore, shallow foundations may allow shallower construction; additionally it can bear heavy loads without needing additional reinforcements.
Glulam’s versatility lies in its ability to be formed into various shapes and lengths, making it a suitable option for curved and sculptural applications. Furthermore, this material can be utilized both residentially and commercially – for instance as garage door headers in homes as well as concealed floor applications where beams may partially or fully hidden beneath floor joists.
For those seeking an even more eco-friendly option, glulam may be an ideal material choice. Constructed from durable woods such as spruce, fir and larch and recycled lumber – it also consumes considerably less energy in its manufacturing, distribution and treatment than concrete or steel structures – not to mention being manufactured using less energy overall! Glulam frames also boast significant acoustic performance benefits when coupled with porous acoustic paneling to give it optimal acoustic performance when coupled with porous panels!
Installation of the Windows and Doors
Glulam is an ideal material to create large open spaces that would otherwise be difficult to realize with traditional wood frames. Architects are increasingly turning to Glulam in homes, schools and office buildings alike for its stunning architectural possibilities.
APA EWS-trademarked (Engineered Wood System) glulam beams feature zero or very flat factory built-in cambers that make connecting them to other wood framing components – such as garage door headers – easier.
Gulam offers four appearance grades–framing, industrial, architectural and premium–which make it a top choice for exposed applications such as vaulted ceilings and designs with open spaces. But its versatile use also extends into hidden applications, including simple purlins and roof decking planks as well as purlins and ridge beams. Furthermore, its excellent thermal properties prevent thermal bridging, creating an efficient building envelope assembly when combined with additional insulation materials.
Final Inspection
Glulam is one of the most versatile engineered wood products on the market, combining strength and beauty. Easily formed into complex curved shapes to meet specific design requirements, as well as being sustainable building material (sourced from sustainably managed forests) which fits with today’s growing trend toward environmentally responsible building practices. Furthermore, its strength makes glulam an excellent choice for large-scale commercial projects as well as high performance homes.
Glulam differs from traditional sawn timber in that it consists of lamellas that are carefully chosen and assembled using water-resistant structural adhesive, eliminating knots and creating strong and stable structures. Kiln drying removes moisture which reduces shrinkage/warping risks as well as insect damage to make wood less vulnerable to insect attack; furthermore this process provides greater precision than sawn or built-up timber when designing/ fabricating large scale elements with glulam elements.
Due to its unique manufacturing process and weatherproof glue application, glulam is stronger and sturdier than traditional solid-sawn lumber and can easily be bent into curved shapes for specific design applications. Unlike steel beams, which cannot be formed into intricate curves like those found in bridges and other architectural structures. Furthermore, computerized machinery allows members of glulam panels to be cut to exact specifications; saving both time and money on on-site fabrication processes.
As such, glulam has become an excellent material choice for modern home designs with vaulted ceilings and open spaces, as it spans long distances using relatively light-weight members. Furthermore, its ability to span long distances with relative ease has led to it being utilized extensively across British Columbia, including one 44-metre pedestrian bridge crossing one of Burnaby’s main thoroughfares and an undulating pedestrian bridge in Princeton, British Columbia.
No matter its purpose – garage door headers, floor girders, roof trusses, purlins or cantilever beam systems – glulam is easy to specify, easy to work with and delivers performance unrivaled by other materials. Available in four appearance grades (framing, industrial, architectural and premium), it can be customized according to project aesthetic preferences and manufactured according to ANSI A190.1 standard requirements for production of structural glued-laminated timber products; additionally APA member manufacturers must comply with ANSI A190.1 requirements regarding production glued-laminated timber production while its Form S475 provides recommended preliminary design loads for both simple-span and cantilevered cantilevered beam systems.
