Welcome to the pioneering realm of Glulam, a harmonious fusion of nature and modern manufacturing techniques. Glulam, short for glued laminated timber, is crafted through a specialised manufacturing technique wherein multiple smaller layers of timber are bonded together to form a singular, robust component. This innovative process facilitates the creation of timber elements that may otherwise be challenging to obtain in solid timber, either due to their substantial size or unconventional shapes.

Your Vision, Our Capabilities

Masswood’s glulam capabilities are versatile to accommodate a broad spectrum of projects, ranging from individual glulam beams utilised as lintels and posts, to the structural framework, such as portal frames, for residential and commercial new-builds and expansions.

The Benefits Of Glulam

Elevating Sustainability and Efficiency in Construction

Boasting inherent advantages that surpass traditional steel and concrete solutions, Glulam offers a compelling combination of structural performance, environmental benefits, and aesthetic appeal, making it an attractive choice for sustainable, diverse and thoughtful construction projects.

Good for the planet

Timber is sourced from sustainably managed forests, which are renewable and regenerative. Trees absorb and store carbon dioxide as they grow. Using timber in construction locks up this carbon, helping to mitigate climate change by reducing atmospheric CO2 levels.

User Friendly

By combining lightweight handling, ease of modification, and dependable fastening, Glulam empowers builders to make precise adjustments and fittings during construction. This capability not only reduces logistical challenges but also accelerates the installation process.

Durable & Strong

Engineered to withstand diverse environmental conditions and loads, glulam members offer reliable performance over extended lifespans. Compared to solid timber, Glulam offers superior strength and stability, facilitating the construction of larger and more resilient structures.

Aesthetic Appeal

Glulam leverages the natural beauty of timber to create stunning, warm spaces. When incorporated into designs, it serves as a visually striking feature that exudes timeless elegance while seamlessly complimenting materials like steel, stone, and concrete, making it a preferred choice for designers who prioritise both aesthetics and environmental responsibility.

Fire Resilient

Glulam is highly resilient when exposed to fire due to its natural insulating qualities, which enable it to burn at a slow, predictable rate. Under intense heat, glulam chars gradually, forming a protective layer that safeguards the inner core. As a result, glulam maintains its integrity for a longer duration, even in high-temperature situations.

Design Versatility

The flexibility of Glulam allows for creative freedom in architectural design enabling the creation of unique and complex structures. From soaring arches to sweeping rooflines, glulam empowers architects and engineers to push the boundaries of sustainable design.
