Air Tightness & Building Membranes
Building membranes have various purposes in modern construction such as preventing condensation and dampness. Generally, this term describes thin layers of waterproofing, breathable materials that are a couple millimetres in thickness. There are two main types of building membranes – sheet-based or liquid applied.
Here at Intelligent Membranes, we specialise in the highest quality liquid applied membranes. Our range features air tightness, vapour control, waterproofing and weatherproofing products that can protect your building inside and out. All of our products are brush or spray applied for your convenience and can be used on either the walls, floors or roof of your building.
