coldbuilding

Coldbuilding is a construction technique that involves building walls using insulated panels or blocks while the structure is unheated. This method contrasts with traditional construction methods, where walls are typically built with a skeleton framework and then insulated. Coldbuilding involves assembling the walls with the insulation already incorporated to reduce heat loss.

The process begins with the installation of foundation elements, such as footings and walls. Insulated panels or blocks, often made of materials like polyurethane foam or expanded polystyrene, are then stacked to form the wall structure. Building services, such as plumbing and electrical systems, can be integrated into the insulated panels.

Proponents of coldbuilding argue that it offers a number of benefits, including improved thermal efficiency, reduced material waste, and faster construction times. Research has also demonstrated that coldbuilding walls can provide better soundproofing.

However, coldbuilding requires specialized skills and equipment, which may inhibit its adoption among general contractors. Coldbuilding elements must also be carefully selected and installed to ensure compatibility with the chosen building envelope system. Additionally, specialized fasteners and fixings are used to secure the coldbuilding elements together. Closed cell foam is sometimes used as an adhesive to minimize water intrusion. As a result, coldbuilding is typically used in more specific regional applications and it is less common compared to other building techniques.
