Knauf Loft Roll Manufacturing process

The production technology used in the design stage makes it easier than ever to handle. Although customers frequently comment on how soft the product is to the touch, we do advise wearing appropriate PPE when handling any form of loft roll as it could potentially cause irritation to the skin.

Typically, handling glass wool materials such as loft roll could potentially damage or scratch your skin. The product is now categorised as minimal itch because of new industrial production procedures that have emerged in recent years. It is recommended to always use caution while handling any mineral wool to avoid irritating yourself or others. Utilise a crawl board to move around securely in a loft and use caution when moving around.

Installing Knauf Earth Wool 100mm Loft Roll

Loft Roll is multi-purpose although it is primarily used in loft applications. Since Knauf 100mm Loft Roll comes in a roll form, it is easy to install and roll out. Be cautious not to obstruct any of the loft’s ventilation. After it has been rolled out, the product should always be shaken to recover the entire 100mm thickness.

Knauf 100mm Loft Roll is combi cut, making the product even more convenient. This suggests that the loft can be insulated by stacking the loft roll in two layers. At either 600mm or 400mm intervals from the joists, the first layer should be placed. The extra layer should be positioned at right angles to the joists. Knauf 100mm Loft Rolls are slightly perforated. It can be placed between two joists or uncut to maximise the full width of the roll.

How to store 100mm Knauf Loft Roll

Knauf 100mm Loft Roll should be stored in a dry area and preferably kept inside. If there is no other choice, keep the rolls off the ground and covered. Harsh weather conditions can cause a reduction in quality so it is important to store the loft rolls correctly when possible.

    The website was very clear so I knew exactly what to expect. Used another company (who I won’t name) and got something completely different. With your website you know exactly what you are getting so will use again on the next project. Cheers
