Hålväggens

Hålväggens, often referred to as hollow-wall in English, is a type of construction commonly found in buildings. It refers to a wall system that is not solid throughout but rather consists of an inner and outer layer with an empty space, or cavity, between them. This cavity can be of varying depth and may be left empty or filled with insulating material.

The primary purpose of a hålväggens is to provide thermal insulation. The trapped air within the cavity acts as a barrier to heat transfer, helping to keep interiors warmer in winter and cooler in summer. This contributes to energy efficiency and reduced heating and cooling costs. In addition to insulation, the cavity can also help with soundproofing, further enhancing the comfort of a building's interior.

Hålväggens construction can be achieved using various materials, including bricks, concrete blocks, or timber framing for the inner and outer skins. The cavity can be sealed with damp-proof membranes to prevent moisture ingress from the outside, which is crucial for maintaining the structural integrity and insulation performance of the wall. This type of wall construction is prevalent in residential, commercial, and industrial buildings across many regions.
