Comfortable, robust interiors for homes, schools, offices, and more

It is essential that the homes we live in, the schools where our children learn, and the workplaces we rely on are safe, comfortable and quiet spaces. Everyday use can affect the walls around us, so choosing durable internal wall insulation is important for long-term performance.

Our internal wall insulation solutions are designed to provide acoustic performance between rooms, helping to reduce sound transfer and create more peaceful, private interiors. As an added benefit, they also provide high thermal performance, supporting year-round comfort and energy efficiency.

Knauf Insulation products are silicone-treated with DriTherm® Technology, delivering water repellence and improved durability to help maintain performance over time. For extra peace of mind, our internal wall insulation has achieved FireMark certification for non-combustibility.
