Dobbelvegger

Dobbelvegger, which translates to double walls in English, refers to a construction technique where two parallel walls are built with a gap between them. This gap is typically filled with insulating material. This method is commonly employed in modern building practices to enhance thermal insulation and soundproofing properties of a structure. The air cavity within the double wall acts as a buffer, reducing heat transfer and the passage of sound waves.

The construction of double walls can vary. One common approach involves building two separate leaf walls, often of brick or block, with a specified space between them. This space can range from a few centimeters to much larger gaps depending on the desired insulation performance. Alternatively, a single structural wall can be built with an interior frame that is then clad with an additional layer, creating the double wall effect. The choice of insulation material is crucial and can include materials like mineral wool, polystyrene foam, or fiberglass.

The benefits of dobbelvegger include significantly improved energy efficiency, leading to lower heating and cooling costs. They also contribute to a more comfortable indoor environment by minimizing temperature fluctuations and reducing noise pollution from external sources. In some contexts, the cavity can also facilitate the installation of services like electrical wiring and plumbing, keeping them out of sight and protected. While the initial construction cost might be slightly higher than for single-wall constructions, the long-term advantages in terms of performance and comfort often outweigh this initial investment.
