Mészkvel

Mészkvel is a traditional Hungarian architectural term referring to the cavity between a wall and the exterior facade. It is a space located outside the building envelope, often above windows and doors, which has been used in Hungarian construction for centuries to improve building insulation and facilitate exterior maintenance.

This cavity typically ranges in width from 0.5 to 1 meter, and is usually accessed from the exterior via a small opening or hatch. The mészkvel has several functions in Hungarian architecture. Firstly, it provides a space for insulating materials such as glass wool or mineral wool to be installed, improving the building's thermal performance and reducing heat loss.

Secondly, the mészkvel allows for the installation of exterior fixtures such as gutters, rainwater outlets, and ventilation systems. Its design also facilitates regular maintenance and repair of exterior features, including window frames and siding.

Mészkvel's have been widely adopted in Hungarian residential and commercial construction, particularly in the 19th and early 20th centuries. In many parts of the country, particularly in rural areas, this type of cavity wall construction is still seen in older buildings.

It's worth noting that the mészkvel has also been incorporated into modern Hungarian building codes, with some designing it to be part of external wall insulation systems. However, its primary use remains a space for insulation and for facilitating the regular maintenance of exterior features. In summary, the term'mészkvel' refers to the key element of Hungarian cavity wall construction and insulation strategy.
