Živjo!

Prosim ne se mi smejati,ampak nujno rabim razlago razlike med polyestrom in PVC (kot material za streho)

Hvala!

Khm, ne bomo se smejali, ma to še ne pomeni, da razumemo vprašanje.

Jaz bi na pamet rekla, da ni za streho noben od dveh materialov uporaben, res pa je tudi, da nisi povedala, za kakšno streho.

PVC je polivinil klorid

streha oz. material za tende, šotore…

PVC ni odporen na svetlobo in menim, da ni primeren za tende, šotore itd.

Primerjava ostali materiali:
Ultraviolet light is invisible and is always present during the daytime. It causes fabrics, such as nylon, polyester and polyethylene, to degrade and breakdown over time. Oddly enough, those are the very materials best suited to making tents. A tent, screen house or canopy made from any of those materials is subject to ultraviolet damage. Polyester lasts longer than nylon in resisting damage and dark colors fare better than light colors. A nylon tent left up continuously for about 3 months will be completely destroyed by ultraviolet light. A polyester tent fly would last about 5 months before it succumbs. Polyethylene has about the same UV characteristics as polyester. The material looks thinner, dryer and fades as the damage progresses. Finally, the material will shred and fall apart. The only exceptions would be canvas tents which are more durable and much longer lasting. A canvas tent can be used year after year with little or no ultraviolet damage.
