Rigid Walls
Rigid walls are typically made from materials such as expanded polystyrene, mineral wool, or stone wool. These materials provide superior insulation, as the carbon dioxide cells packed in the material become a thermal barrier from the outside elements. The rigid walls are constructed of panels that attach directly to the building’s exterior, creating a continuous layer of insulation. The panels can also be used to improve a buildings appearance, as they can be finished with cladding or other external finishes.

Flexible Walls
Flexible walls are made from materials that expand and contract with the temperature changes, such as expanded polyurethane. Unlike the rigid walls, flexible walls are applied like a plaster and can fill the gaps in uneven surfaces to provide a uniform insulation. This method of insulation is cost effective and easy to install, making it ideal for large scale projects or regular maintenance. Additionally, the flexibility of the material allows it to be applied over almost any surface.

Vapor Permeable
Vapor Permeable external wall insulation is designed to provide both insulation and airtightness. It allows moisture to escape from within the structure but prevents it from entering, making it a great option for buildings in humid climates. It also helps increase the stability of the walls by reinforcing their strength and preventing water from entering. The material is breathable, so it can allow for the exchange of fresh air, keeping the building free from mold and other allergens.
