Attic Trusses
Calldene Attic Trusses (also known as “Room-in-the-Roof” trusses) are the smartest way to increase the habitable area of a property without expanding its footprint. By integrating a high-strength floor structure directly into the roof profile, these precision-engineered timber components allow you to transform a standard cold roof into a warm, functional living space—ideal for bedrooms, home offices, or playrooms.
Manufactured using MiTek Pamir design software, our trusses are custom-built to your exact project requirements, offering a seamless alternative to complex traditional steel or loose timber construction.
Key Features & Benefits:
- Up to 50% Faster Installation: delivered to site as pre-fabricated units, our trusses eliminate the need for complex on-site carpentry. A complete roof structure can often be craned into place and braced in a fraction of the time required for traditional “cut and pitch” roofs.
- Clear Span Flexibility: Engineered to span from wall plate to wall plate, attic trusses often eliminate the need for internal load-bearing walls. This grants you total freedom to design open-plan layouts on the floor below.
- Cost Efficiency: While the initial unit cost is higher than standard trusses, the overall project cost is significantly lower due to savings on steel beams, labour, and reduced construction time.
- Precision Engineering: Designed with industry-leading MiTek software, ensuring every joint and structural member meets rigorous stress-grade requirements.
- Sustainable Construction: Timber is a renewable resource, and our pre-fabrication process minimises on-site waste.
Ideal Applications:
