In Mill Construction: Materials for Exterior Load-bearing and Non-load-bearing Walls
In mill construction, the choice of materials for exterior load-bearing and non-load-bearing walls plays a crucial role in ensuring the structural integrity and overall durability of a building. This article aims to provide a clear understanding of the materials used in mill construction and their benefits. Whether you are a homeowner, architect, or builder, this information will help you make informed decisions when it comes to constructing or renovating a mill building.
I. Exterior Load-bearing Walls: Materials and Benefits
Load-bearing walls are essential for providing structural stability and supporting the weight of the building. In mill construction, the following materials are commonly used for exterior load-bearing walls:
- Durable and fire-resistant material
- Provides excellent thermal insulation
- Requires minimal maintenance
- Offers a classic and timeless aesthetic appeal
- High strength and load-bearing capacity
- Fire-resistant and durable
- Low maintenance requirements
- Provides excellent sound insulation
- Structural Steel:
- Offers exceptional strength and flexibility
- Allows for large open spaces and flexible floor plans
- Resistant to fire, pests, and rot
- Eco-friendly, as it can be recycled
Exterior load-bearing walls made from stone or brick. Beams and columns of heavy timber with cast iron connectors used to cover joints. Floors of laminated, thick grooved or splined planks. Roofs made from laminated or thick splined planks were supported by timber arches and trusses or beams.
Which construction classification includes buildings with exterior load bearing walls composed entirely of wood?
Type V Construction
It is the only category of construction that allows combustible exterior walls as well as combustible structural members on the interior. Frames, walls, floors, and roofs are made entirely or partly out of wood.
What is the difference between mill construction and ordinary construction?
Ordinary construction uses floors, roof, and interior walls of balloon frame construction, while Mill construction uses heavy timber framing for internal construction. The heavy timbers and decking used in Mill construction are slow to catch fire.
What types of wood products are used to frame heavy timber buildings?
MASS TIMBER CONSTRUCTION uses large prefabricated wood members made from cross laminated timber (CLT) or structural composite lumber (e.g., laminated veneer lumber, laminated strand lumber, parallel strand lumber) for wall, floor and roof construction.
What are load-bearing walls made of?
Load-bearing walls are made out of resistant materials, such as stone, steel, concrete, or brick. These materials make it possible to bear large loads without any deformations. Load-bearing walls act to support the building.
What is the purpose of firecutting a heavy timber beam?
Beams used in Heavy Timber construction are sometimes firecut. This is done to: allow the beam to rotate out of the wall if it burns through.
