This relationship between moisture and insulation, particularly with solid walls, is essential for the structural health and performance of the building.

−	Condensation occurs when warm air comes into contact with a surface that is cooler, causing the moisture in the air to condense into water. Interstitial condensation, on the other hand, happens when water vapour reaches a point that is 2-3 degrees cooler and condenses within the structure of the building. If insulation materials slow down the escape of moisture or are non-breathable, they can inhibit the ability of moisture to escape from the building fabric. This can lead to serious issues with interstitial condensation, dampness, mould, rot and structural damage.	+	One of the primary concerns when it comes to solid wall insulation – both in new build and refurbishment projects – is the risk of interstitial condensation.

−	Thermal performance is a critical consideration when selecting an external wall insulation system. The goal is to ensure that the temperature across the entirety of the insulation system remains higher than the dew point temperature of the water vapour. This means keeping the walls warm enough to prevent condensation. To achieve this, vapour control layers can be installed on the warm side of the insulation to slow the rate of vapour entering the wall. However, it is crucial to eliminate thermal bridging to avoid cold spots in the walls where condensation can gather. Additionally, a well-planned ventilation strategy and regular heating during colder weather are essential for maintaining warmer walls and preventing condensation.	+	Thermal performance is a critical consideration when selecting an external wall insulation system.

	With the right EWI insulation system in place, buildings with solid walls can act like a battery, absorbing, storing and releasing energy. It creates spaces with a high thermal storage mass, meaning overheating in summer is much slower to occur, and heat is retained internally during the colder months. We are passionate about raising awareness of the benefits of EWI and have developed a CPD titled: How external wall insulation improves energy efficiency and wellbeing – the proof.
