Boric Acid (in diluted concentration – boric water) antiseptic.
Magnesium Sulphate – substance for fireproof impregnation of textiles, fertilizer, ruminant feed additive. The appropriate combination of these ingredients in cellulose thermal insulation causes increased resistance to fire, mould, fungi and also repels insects and small rodents. The additive is homogeneously distributed in the material and connected to the fibres due to a special technological treatment. It cannot be mechanically separated from the fibre by conventional means.

Yes, fibrous insulation made from fibres modified by repulping paper insulates very well. At the same thickness, its thermal insulation capabilities are comparable to e.g., polystyrene, mineral or glass wool.

Climatizer Plus – Cellulose-type thermal insulations are provided with additives directly in production that significantly slow down degradation by fire. When heated above a temperature of about 120 degrees, the additives cause sudden wetting and thus slow down the burning process, to the extent that a structure filled with Climatizer can withstand the onslaught of fire longer than a structure that is not insulated or insulated with, for example, self-extinguishing polystyrene or fiberglass-based insulation.

The second, but less well-known basic property of borate salt additives is protection against mould, fungi and small rodents. During the period of use of Climatizer in Canada since 1977 and in the Czech Republic since 1991, a reduced occurrence of these rodents in buildings insulated with the Climatizer has been demonstrated.

Climatizer is a fibrous substance consisting of cellulose fibres and other components obtained from paper. In addition, inorganic borate or magnesium salts are added, which are mainly of mineral origin, have very good stability and at the same time protect the fibre. Correctly stored rolls of paper were found even after 4000 years, a properly stored Climatizer has at least the same chances!

To understand the latest trends in the use of cellulose insulation in construction, it is always helpful to look back into the history of how it all began. In its simplest form, insulation was actually used for the first time during the first cave man, dressed in skin and rested on a piles of straw. Why? Simply, there was a need to insulate himself and he did it by the natural ways using animal and plant fibres. Many years have passed and this form of insulation is used in the 21st Century within modern buildings and structures.

The problem of water and moisture arising or flowing into the insulation layer must be looked from several points, which apply almost universally to all types of fibrous insulation without special impregnation and protection.

Climatizer plus is a loose fibre insulation that is applied by blowing with application machines. It is necessary to distinguish which structure on the construction site the material is applied to.

• Material with the lowest possible density is applied to horizontal surfaces
• On sloping surfaces when insulating between rafters and the like, the amount of material per 1m3 must be increased to approx. 40-60 kg
• Filling vertical walls is the most demanding. This must be used for each m3 of Climatizer plus.

This application is aimed at spraying cold roofs and structures on which condensate forms during the transition period of sudden temperature changes, which then runs off. This issue can be divided into two basic areas of spraying:

• Roof spraying under which an insulated suspended ceiling is installed
• Roof spraying where there is no soffit

Climatizer plus is thermal insulation based on fibre obtained from wood-based paper. The fibre is made from recycled newspaper and is the main primary commodity of the cellulose insulation. The application is quick, easy and efficient and uses a blowing machine for this process. This means that it reaches and adheres to all areas and provides a seamless layer within joints. Additional benefits:

• Excellent thermal insulation effects
• Capabilities of low diffusion resistance and high resistance to air flow through its cross-section (it allows moisture to be removed well while its layer is prevented from being cooled by flowing air)
• Less waste
• It balances perfectly temperature and humidity, if the construction layer allows it
• Ecologically friendly product since 1994.

Blowing primarily means less disruptions for customers. Single individual applies the insulation to the walls and ceilings – Another individual continues to load the application machine with fibre. Insulation of a typical home can be completed quickly and efficiently, many within one day depending on application.

Yes, the blow-in insulation can be used to subsequently insulate old houses. During the inspection, an assessment is made as to whether further measures are necessary. These measures include the ventilation of the attic or the insulation layer, if necessary, the choice of the insulation material Climastone (blown fibre insulation made of rock wool) for the areas surrounding the chimney body and areas of risk, hot air heating systems. The cellulose is suitable for areas up to 105°C and Climastone can come into contact with a temperature of up to 1,000°C.

The material can, but does not have to be covered. With the roof of a bungalow, where it is inflated onto the ceiling of the living quarters, the insulating material no longer has to be covered because it is not assumed that one would enter this space. Spaces that are entered from time to time or in which something is stowed away, the insulating material can be covered with a fabric and walkways can be installed. For spaces that are intended for immediate or future permanent use, we have a system of expanders. These are stands with the height of the insulation layer, which are placed on the original floor before the floor is covered with insulation. After laying the insulating material, walkable panels are installed on top of the expanders. When we fill the ceiling, the original floor remains unchanged.

Yes, this is where Cellulose is excellent, as it insulates very well and, in the summer, its accumulative abilities stand out. During a hot day it warms up very slowly and on a cooler night it releases the heat again. In this way, the attic stays cool for a much longer time. However, one must remember – to blow the insulation before the roof is finished. It is important to use the right layers, both on the underside towards the residential interior and also on the outside towards the roof. On the inside, they are gridded vapor barriers (e.g., Intello or DB +), on the outside, they are diffusion-open membranes intended for direct contact with the insulation or wood fibre boards with water impregnation. Ideally, the roof should have a ventilated composition.
