Lightweight membrane structures or tensile structures have become an excellent option when covering spaces, and their application in projects in different sectors has become increasingly recurring.
But the lightweight structures of Membrana are unfortunately also not exempt from piracy, since it is increasingly common to find doormen who lie to their clients and affirm that they are also experts in the manufacture and installation of tensile structures, when this is not the case.
This lack of professionalism has led some to view membrane lightweight structures or shade cloth covers as unsafe.
In the last construction fairs in which we have had a presence, we were surprised to meet more than one attendee who said they had a bad experience with a light membrane structure, as it easily collapsed on a windy day.
In order for a client to be sure that they are hiring a professional textile architecture firm, the following points must be taken into account:
1. Years of experience.
The first membrane lightweight structures was installed in Mexico more than 20 years ago, but these boomed just a few years ago. Companies with 10 to 15 years of experience in the market are the most reliable, having worked on the development of tensile structures before they became popular.
2. Your knowledge of materials for membrane lightweight structures.
Nothing distinguishes an expert from a hobbyist more than his knowledge of materials for making membrane lightweight structures. And it is that although there are national materials, there are many imported materials for the production of tensile structures or lonaria. These are the most common brands: Verseidag, Dickson, La Marina, Mehler, Serge Ferrari, Sioen, among others.
If the textile architecture firm is unfamiliar or does not use any of these brands, it will most likely deliver poor quality and poor quality Membrane lightweight structures.
There are some other materials such as Lac650, Sunbrella, Fortoflex, Oplex, Limor, Stamisol, Plastik Planen among others whose use is common in flat awnings of minimum dimensions and its use is not recommended for membrane lightweight structures or tensile structures. If the company with whom you are quoting a membrane lightweight structures project offers them to you, it is because it definitely does not dominate the subject.
There are other materials such as Comercial 95 mesh shade from Distribuidora Orli or its peers from Limor industries with which textile architecture projects can be carried out on a smaller scale, likewise materials such as textilene, stamisol and some other materials classified as mesh can be used in roofing for attractive shaped facades
3. Your knowledge of wind tunnel studies.
Membrane lightweight structures or lonarias are structures with very peculiar geometric shapes, which is why most of the national and international regulations in the wind design appendices require a wind tunnel study to find the pressures at which they will be. subdued structure
At Hyparch we offer our clients a virtual simulation in a wind tunnel in order to detect when a structure can be sensitive to dynamic effects and thus avoid possible structure collapses.
4. The price of the membrane lightweight structures.
With tensile structures, as well as with other products or services, cheap is expensive. If the project you quote with an office is disproportionately cheaper than others or similar projects on the market, you have to be careful
These points are the most important to review when hiring a textile architecture office, however, it is also recommended to ask the office of your project portfolio to see the works they have done for other clients.
