Cellulose Paper Insulation – What is it?
UNIVERCELL+ is thermal and acoustic insulation made of loose, free cellulose fibres obtained from recycled and shredded paper. It can be loosely applied, wet projected on vertical walls or can be blown in cavities with pneumatic blowing machines.
UNIVERCELL+ is used in new construction or renovation of:
• Loft roof spaces
• Infill insulation for walls, floors and ceilings.
Suitable for residential buildings, offices or public buildings, as well as industrial and commercial buildings with low or medium humidity.
Store on a flat surface, keep dry and protected from UV rays. Pallets may not be placed on to each other during storage.
Installation of Univercell+ Paper Insulation
UNIVERCELL+ is applied using a pneumatic device designed for cellulose insulation, equipped for carding and regulation of the air and material flow. The application of cellulose insulation is carried out in accordance with the recommendations:
• Insulation of loft spaces
• Insulation of vertical cavity walls
It is not allowed to bring cellulose wadding into contact with heat-emitting elements such as chimneys, recessed spotlights, extractor hoods, electric coils, transformers, motors and all other electrical appliances.
Always consult the local regulations and installation guidelines of the manufacturer.
Insulation of loft spaces by BLOWING
• UNIVERCELL+ is blown onto the floor or between the framework of the ceiling.
• Insulation of vertical walls by BLOWING
• UNIVERCELL+ is injected under high pressure into a closed vertical cavity wall.
• The device settings are adjusted to achieve a density of 50 to 60 kg/m³.
• The thermal resistance is determined based on the thickness and the density.
Insulation of vertical walls by WET PROJECTION
• UNIVERCELL+ is applied under pressure combined with a small amount of water, on an open vertical wall.
• The device settings must be adjusted to limit the amount of water mist to be used and to achieve a density between 40 to 50 kg/m³ when the insulation is dry.
• The thermal resistance is determined based on the thickness and the density.
FAQs
Frequently Asked Questions (FAQs) about UNIVERCELL+ Insulation
What is UNIVERCELL+?
UNIVERCELL+ is a thermal and acoustic insulation product made from loose, recycled cellulose fibres, primarily from recycled newspaper. It is designed for use in new builds and renovations, helping improve energy efficiency and acoustic performance in buildings.
Where can UNIVERCELL+ insulation be used?
UNIVERCELL+ can be applied in:
• Loft roof spaces
• Cavity walls (between timbers)
• Floors and ceilings
Suitable for residential, commercial and industrial buildings with low to medium humidity.
How is UNIVERCELL+ installed?
It is applied using a pneumatic blowing machine, which controls both the material flow and air distribution for even insulation coverage. It can also be installed as loosefill in horizontal applications.
What are the key components of UNIVERCELL+?
The product consists of:
• 89 % selected recycled paper
• 4 % boric acid
• 7 % magnesium sulfate
(± tolerances)
How does UNIVERCELL+ perform thermally?
UNIVERCELL+ offers thermal conductivity values between 0.039 and 0.042 W/m·K, depending on how it is blown and its final installed density.
Can UNIVERCELL+ resist mould and moisture?
Yes. It has zero biological resistance (mould growth) and a low water vapour diffusion resistance coefficient (µ = 2).
Is UNIVERCELL+ safe to use near heat sources?
No. UNIVERCELL+ should not be installed in contact with heat-emitting elements such as chimneys, recessed lighting, electric coils or other appliances.
What fire classification does UNIVERCELL+ have?
The material has a reaction to fire classification of E according to EN 13501-1, making it suitable for standard building insulation applications.
How should UNIVERCELL+ be stored?
Store the product on a flat dry surface protected from UV exposure. Avoid stacking pallets one on top of another during storage.
How much UNIVERCELL+ do I need?
Coverage depends on the required insulation thickness and density. The datasheet provides recommended minimum thicknesses and bags per 100 m², based on different installed densities. As an indication at 100mm you can expect to achieve the following
Dry blown – open horizontal (lofts)
Density: 23 to 35 kg/m³
Coverage: 5.43 to 3.57 m² per bag
Wet projection – vertical walls
Density: 40 to 50 kg/m³
Coverage: 3.13 to 2.50 m² per bag
Dry blown – closed vertical walls (dense pack)
Density: 50 to 60 kg/m³
Coverage: 2.50 to 2.08 m² per bag
