MATERIALS AND SHADECARD

Textile materials
The material used is essential for correct function of the outlets that meets requirements of technical regulations and provides sufficiently long service life. (For further details see the article published in the VVI journal. (Here in PDF)). Our products are manufactured only of synthetic materials and their basic overview can be found in the following table:


The company Prihoda s.r.o. focuses on the quality of the materials used. In all cases these are special fabrics that passed a long development phase in order to achieve as high utility value for customers as possible. The PMI/NMI fabrics provide all the below listed benefits already in the standard design (without any extra charge).


Fabric - Prihoda PMI	Fabric- other producers
(Endless fibres)	(Staple fibres)
.: High strength Our basic PMS/NMS/PMI/NMI fabrics show highest strength. In the texture it is 2100 N/10mm, and 1100 N/10mm in the woof. Thanks to these parameters, their rupture is practically out of the question.
.: High fire resistance The PMI/NMI fabrics are certified according to EN 13501-1 with an excellent result. They achieve classification in B-s1,d0 class which means non-spread of fire, minimum development of smoke and no dropping of melted material. The NHE fabrics even conform to the A class requirements.
.: Negligible outlet of particles Due to using endless fibres, all our fabrics can be used in the so-called clean rooms up to the class 10000. Laboratory tests demonstrated almost zero outlet of particles from materials in operation.
.: Antibacterial effect Special treatment guarantees killing of bacteria that are settled in the fabric. This effect does not vanish even after multiple washing. After ten washing cycles it still conforms to the requirements of relevant standard which means almost a lifetime effect, considering low frequency of washing (see the next point).
.: Easy to maintain Our fabrics made of endless fibres are very practical and do not allow settlement of impurities from the passing air. This air is distributed through the holes, and the textile diffusers remain inside almost clean (in usual environment). They do not require additional maintenance than outer dusting. Washing usually comes only due to sanitary or esthetical reasons.
.: Permanency of look Thanks to endless fibres, the look of the fabric does not change even after many washing cycles, unlike materials made of staple fibres. Fabrics made of staple fibres that are intensely contaminated with the amount of settled dust get grey, and more and more fibres come out of the surface. Our PMI/NMI/PMS/NMS's are not devalued by washing in any manner whatsoever.

How choose a suitable fabric?
When selecting material, bear the following information on mind:
1/ Fire resistance. Our fabrics show 3 levels of fire resistance.

Highest fire resistance (identified with “E” as "excellent" in the specification) means fully inflammable material. In this class, considering the price, we only use fabrics of fibreglasses with polyurethane coating. However, these exist only impermeable and are less strong and more fragile than polyester fabrics of medium weight.	Increased fire resistance (identified with “I” in the specification) means excellent non-flammability and very low smoke development. These materials conform to the requirements for use in an absolute majority of spaces.	Raw polyesters or foils (identified with “S” as "standard" in the specification or “F” as “foil”) are very little resistant. They can be used in an environment where no fire resistance is required.
2/ Strength and cleanability. Fabrics are divided in 3 categories by weight.

Light (marked “L”). These fabrics weigh between 75 and 100 g/m2. Diffusers made of these materials can be well inflated with only 20 Pa of static pressure. On the other hand, they have lower strength and especially resistance to rupture. Except NLF they can be washed in a washing machine.	Medium (marked “M” ). These fabrics weigh between 290 a 330 g/m2. These show highest strong-hold values and resistance to rupture. Minimum overpressure for inflation is 50 Pa. They can be washed in a washing machine.	Heavy (marked “H”). These are fabrics coated with a PVC or polyurethane layer, and therefore can only be impermeable. They cannot be washed in a washing machine but can be cleaned with a stream of water. This makes them convenient for mostly contaminated environment.
3/ Permeability

Only in permeable materials condensation of water on the surface of diffusers is eliminated during cooling below the dew point of the environment.
