The goal with every building is to provide protection from the environment. That is the same objective whether it is a home, a shed, or a massive public or commercial property. At the same time though, the buildings need to be comfortable for various activities. An important thing you need to consider here is permeable or impermeable facades. We want to have a closer look, then if you need advice from an architect in London, you can speak to us.

Traditional materials

Ultimately, the goal was impermeability to prevent external elements from getting into the property. However, a number of traditional building materials are porous and permeable to some extent. This includes timber and brick. As a result, they can allow some level of water and air to enter the property. In the worst cases it could lead to issues like moisture infiltration and mould.

A solution here was to use plaster to provide an impermeable layer for interiors. Designs would also create an initial balance, ensuring the conditions inside the property would be correct even with permeable building materials.

Newer options

Today there are more impermeable materials for facades. Using them, the goal is to provide effective separation between the internal spaces and the external elements. They can ensure that no external moisture or air can enter the property through them. They can even block heat and cold, keeping the interior temperatures consistent.

There are some concerns here though. It can be far more complex than you first thought. Talking to a reliable architect in London is a great idea.

For one thing, using impermeable materials can mean there is more demand for mechanical systems to control temperatures, moisture levels, and air quality inside the property. It can be costly to install and maintain them.

A major concern is adding impermeable materials to older structures. While it offers the benefits of improving air tightness and heat retention, it can actually lock moisture in the walls. That can lead to serious structural problems.

A balance

What we actually need here is to achieve a balance, ensuring you account for the complex interplay between materials. This can involve combining permeable and impermeable options. A good idea is to have a hybrid of natural and mechanical systems, especially for airflow.

At the end of the day, the goal should be as always to ensure that interior spaces are comfortable for inhabitants. It is even more important with the impacts of climate change. In addition, you should look at sustainability.
