Comparison of the properties of protection against snow, lightning, rain

Today, it is rarely used for roofing slate. Sales have more modern materials, which have a significant advantage to the slate. Metal and ondulin now use more and more often. But which of these two materials is better for the roof at home? Consider this article the advantages Ondulina front with metal.

It is these two roofing material is the most popular to date. Compare the features, benefits Ondulina front with metal.

metal

Roof covering made of galvanized steel. Ready type of material has a corrugated shape. Top protective coating is applied. However, this coating is easy to damage during transportation or installation. On damaged sections of the corrosion will eventually.

cost of sq. m. lists from 200 - 450 rubles. Lifetime (operating) up to 25 years. The material is lightweight and easy to work with. Resistant to corrosion and fire. Eco-friendly material. Snow from the roof is easily rolled without stopping.

Material poorly transmits the radio signal. Therefore, there will be problems with communication.

Furthermore, the material is very noisy. To avoid this, you need to do additional insulation and soundproofing. It has condensed the property. If you choose metal roofing, it is best to choose a thicker and more zinc content.

ondulin

Ondulina light weight allows the roof without dismantling the old coating:

No need to buy more additional pumping elements. Everything is complete with material. Ondulin not contain asbestos or other harmful substances. High ecological soundproofing. In order to have a more solid roof, you need to put a thick layer of material.

The material is made from cellulose, special additives and bitumen. Bitumen extends deep cleaning.

Unlike metal, Ondulin not prevent the penetration of radio waves. Communication will be much better.

Lightning do not like ondulin. Sheets of material do not accumulate static electricity and the roof does not require additional protection (lightning conductor). Roof Ondulina save money on the purchase and installation of the grounding system. In addition, the roof of Ondulin give peace and comfort during times of rain.

Average sheet thickness of 3 mm. Compacted material, impregnated with bitumen has high strength and can withstand considerable loads (for sq.m. - 960 kg.). It's as packed snow on the roof height of 3.5 meters. Metal can not boast of such durability. Per square meter of 250 kg.

The material will last for more than 45 years. Ondulin resistant to aggressive media, precipitation does not corrode. One minus Ondulina - the loss of color in the sun (1-3 tones). Therefore it is better not to choose bright colors.
