Material

As a company PŘÍHODA s.r.o. places tremendous importance on the quality of the materials used. In every case we use specially developed materials that have been subjected to extensive development testing in order to achieve maximum performance benefits for our customers. The Prihoda Premium (PMI/NMI) fabrics provide all the benefits listed below as part of our standard design (at no additional cost)

List of most important benefits of our fabrics

High rigidity and strength

Our basic Classic, Premium and Recycled (PMS/PMSre/NMS/NMSre/PMI//NMI) fabrics demonstrate optimum rigidity of 1800 N/10mm in the texture and 1000 N/10mm in the weave. These parameters make tearing of the material in normal use almost impossible.

High fire resistence

The PMI/NMI/PMS/NMS  fabrics are certified to European standard EN 13501-1 with excellent results. In this test our fabrics achieve B-s1,d0 classification, which means prevention of spread of fire, minimum smoke production and no burning drops. Glass (NHE) fabrics in fact meet class A requirements. Classic, Premium and Recycled (PMI/NMI/PMS/PMSre) fabrics are also certified to US norm UL 723.

Negligible fibre shedding

Due to the use of endless fibres, most of our fabrics can be used in cleanrooms. Independent laboratory tests demonstratethat there is practically no particle shedding from our material during operation.

Antistatic effect

Woven carbon fibre in Premium (PMI/NMI) and Durable (NMR) materials removes any build up of electric charge from the surface of the fabric.

Antibacterial effect

We utilise a special treatment which guarantees that no bacteria can survive if settled on to our fabric Premium (PMI/NMI) and Durable (NMR). This treatment remains effective after multiple washing. Tests for the European standards found that after TEN washes there was no reduction in the efficacy of the treatment.  This allows us to offer a 10 year warranty on the basis of our minimal maintenance requirements (see the following point).

Easy to maintain

Our fabrics which are manufactured using endless fibres are very effective and mimimalize settlement of impurities from the supply air. This supply air is distributed through the diffuser perforations, and the Fabric Ducts remain relatively clean inside (in a normal environment). They do not require any other maintenance than outer dusting. Washing is normally only required for either hygiene or aesthetic reasons.

Stable Appearance

Thanks to our endless fibre technology, the appearance of the fabric does not change over time, or with multiple washing cycles, unlike materials made of basic fibres. Our Premium, Classic a Recycled (PMI/NMI/PMS/NMS/PMSre/NMSre) materials remain aesthetic after many maintenance cycles.

Selection of the most suitable material

1) Classic (PMS, NMS) or Premium (PMI, NMI)

Fabric Premium is unlike Classic in addition antibacterial and antistatic. Through these properties they are predetermined to use in the environment with the highest hygienic requirements or where it is necessary to prevent arising electric voltage between textile diffuser and earthing. Although the both categories reach usually the rank for the same class according to the flammability, fabric Premium are besides equipped with the special modification for minimization of combustion and fumes.

2) Air-permeable (PMS, PMI, PLS) or non air-permeable (NMS, NMI, NLS, NMR)

The only reason for usage of the air-permeable materials is need to prevent the water condensation on the surface of the diffusers. When in cooling with the temperatures under the dew point the non air-permeable material will behave like steel ducting and it is necessary to use air-permeable fabric, alternatively double or insulated ducting.

3) Light materials (PLS, NLS)

Their lower price is balanced with shorter warranty and life-time. Compared to other fabrics, these light materials are easy to wear out by washing and they will not last more than 50 washing cycles. Thanks to extreme low weight they are pleasant to touch in manipulation.

4) Foils and coated fabric  - Foil (NLF), Plastic (NMF), Glass (NHE), Translucent (NMT)

They can´t be washed in the washing machine, but on the other hand it is possible to clean them with the water flow and with wiping. Foils are the most convenient material with regard to price.

5) Recycled materials (PMSre, NMSre)

They are made of fibers gained through recycling of PET bottles and their usage will contribute to the protection of the environment. Every square meter of this fabric saves 13 PET bottles from the waste dump. Recycled materials aretechnically equal to category Classic.

6) What colour do you want?

Most of our materials are available from stock in the range of 9 colours detailed below (shades may vary). None standard (special) colours are available, but require longer delivery timescales.
