125mm Knauf Dritherm 37 holds great thermal qualities and will keep heat inside the property. In addition, this will reduce energy bills up to 30%. This means cooler summers and hotter winters within an energy efficient property because of the level of internal climate.
Knauf Dritherm 37 has a great fire rating and is non-combustible. As a result, it gives no contribution to the spread of fire. The Dritherm slab will not ignite due to flame exposure.
Glass and Rock Mineral Wool are easier to install correctly than other insulants such as rigid boards. This is because they adapt to any slight imperfections in the substrate and knit together. This eliminates any air gaps. Evidence shows the absence of air gaps is crucial to achieving real performance in the relevant application.
