Climate & Humidity Control Within Heritage Sites

Heritage sites are an important part of our history. They’re places where we can learn, and they’re also spaces we can enjoy and admire. We have to manage and take care of historical buildings to prevent damage and protect any artefacts, relics, records, artwork, books, and objects they home. Climate and humidity control are a major part of the preservation, because we need to maintain specific environmental conditions to prevent moisture damage.

Stately Homes, Castles & Churches

Europe’s rich history means that lots of places are strewn with stately homes, castles, churches, cathedrals, and monuments. Many historical buildings and structures carry cultural significance and are ‘listed’ to keep them as authentic and maintain their integrity and fascination.

The build structure of many heritage sites have stood the test of time of 100s and 1000s of years so far, but they are under threat from the climate and climate change. Changes in humidity and temperature can cause materials to deteriorate noticeably faster. The added risk of more rainfall, stormier weather, and floods also put building preservation under pressure. Each of these elemental instances can raise the  moisture level in the fabric of these structures which can affect their rigidity.

Why are Heritage Buildings Susceptible to Moisture Damage?

Anything built with “breathable” materials like stone, soft brick, lime-based mortars, and lets moisture more easily. Masonry and timber make up the key structural elements of most heritage-listed buildings across Europe. They suffer more from water damage than modern structures with damp-proof courses or damp-proof membranes.

Unregulated humidity can cause mortar to crack and ‘spalling’ in stone and brickwork, while wall rot and the staining of interior finishes appears as water finds its way inside.

As timber breathes, it takes on some of the moisture in the atmosphere and releases it as the air begins to dry out. Over time, this process can cause wood to expand, contract, warp and split, damaging vital parts of a structure, such as joists, beams and floorboards.

Older buildings contain structural and decorative elements that are made from hygroscopic materials that readily attract or absorb water. If left too long, dried too soon, or without due care, structures and items can suffer warping, splitting, rotting, mould growth, crumbling, and other irreversible cosmetic and structural damage.

What Causes Humidity Levels to Fluctuate?

  • The outdoor environment
  • Heating
  • Visitors
  • The building itself

How a Dehumidifier Can Help

By circulating humid air throughout a space, dehumidifiers can physically remove moisture from the air. Used in combination with heating, this ensures a comfortable environment for people inside a church while protecting the building's historic significance.

With the need to restrict moisture levels on these historic sites crucial to their preservation, the growing pressures presented by climate change make systems that control humidity on-site more crucial than ever to avoid costly restoration works or irreparable damage.

Preserve and protect your castles and wider heritage sites from the threat of humidity with the best possible solution. Speak to us today about our selection of stationary dehumidifiers.

Dehumidifiers are available in a range of sizes, for different sizes spaces. There are also a number of different types available, from portable dehumidifiers to wall-mounted fixed dehumidifiers. Compressor dehumidifiers offer a simple, efficient and cost effective solution in spaces above around 5 degrees celcius. In unheated, cold spaces, desiccant dehumidifiers offer the best solution - as they are able to extract moisture in much lower temperatures than compressor dehumidifiers.

We have suitable dehumidifiers available in a range of sizes - so no matter the size of your garage or storage facility, we have the solution ready for you.
