An excellent solution to insulating pitched roofs at ceiling level, this loft roll from Earthwool boasts several unique features that make it ideal for such applications. Suitable for a range of different pitched roofs, it is great on both new builds and renovations.
What is This Insulation Made From?
This insulation has been created using low-density glass mineral wool. This material has been utilised in insulation products for many decades, and with good reason – it is an outstandingly high performing substance, with excellent durability and a long lifespan.
What Thicknesses and Sizes are Available?
This roll is available in several different thicknesses ranging from 100mm to 200mm. While thermal conductivity doesn’t change with the roll thickness, thermal resistance does – it increases alongside the thickness. For example, 100mm rolls have a thermal resistance of 2.25 m2K/W, while 200mm rolls possess a thermal resistance of 4.50 m2K/W.
Is Knauf Earthwool 44 Resistant to Mould and Moisture?
This roll is highly resistant to damage posed by water vapour and mould. It is rot-proof as well as odourless, meaning that it can last for many years in your ceiling without the need for replacement due to wear or damage.
Is This Insulation Resistant to Fire?
This roll achieves an A1 fire rating. This is one of the highest achievable fire resistance accolades on the Euroclass Fire Ratings scale. The roll is non-combustible and is not only resistant to fire-induced damage, but its properties mean it will not aid any flames in spreading.
What level of thermal insulation does this board offer?
The loft insulation roll has a thermal conductivity of 0.044 W/mK – this means this product is capable of exceptional levels of insulation. The quilt is unfaced, meaning the thermal conductivity levels are consistent throughout the material.
Is Knauf Earthwool 44 Environmentally Friendly?
This roll benefits from a Green Guide Rating of A+ - this is due to the lack of certain environmentally damaging properties, as well as a cleaner production process than many other insulation types. For example, it contains no ozone-depleting substances (ODP).
Where Can This Insulation Be Used?
This insulation has been created specifically for the ceiling of your building, where its various features allow it to perform at its very strongest. Designed for cold pitched roofs in particular, it is a testament to the manufacturer's ability to create highly effective specialised insulation products.
