ruberoid

Ruberoid roofing material is considered to be reliable.Cheap and practical to use a material which is very popular for many years, and today has not lost its relevance.Due to the special composition of the material it has many positive qualities.

Properties

• tensile strength;
• resistance to various climatic influences;
• long service life;
• does not require special maintenance.

Roofing material made from a special special density roofing paper.At first he impregnated petroleum bitumen, after the top layer is covered with refractory bitumen with the admixture of different powders.Through this melting temperature of the outer layer of material of about 80 ° C.In this article you can see photos and video reviews of roofing material.

Types

roofing Roofing material is divided into two classes:

• roofing "upper" with a thickness of 4.5-5 mm;
• backing "low" with a thickness of 3-3.5 mm.

There are several kinds of roofing material.Its main difference is in the type of powder.

1. With one-sided coarse powder.It can be used as a waterproofing or laying on the upper and lower layers.
2. With coarse powder on both sides.As a general rule, powder is crushed stone.This form can only be used at the top of the roof.
3. With scaly powder of mica slate.It can be covered with a one or both sides.It is used for device the top layer of the roof.
4. With fine-grained powder.It can be processed as one or two sides.Apply a waterproofing material or lower the roof covering.
5. With dust powder.Also applicable for the bottom layer of the roof and as a waterproofing.

Specifications roofing

most common roofing material is a brand of the RCP-350.Technical characteristics allow its use as a backing layer or as a temporary roof covering.Its parameters are:

• weight - 24 kg;
• Tensile strength at yield, at least - 274 H;Water absorption
• for 24 hours, no more than - 2% by weight;
• temperature flexibility on a bar R = 25 mm, not more than - 5 ° C;
• Heat resistance, not less than - 80 ° C;
• cover type: upper - talc, bottom - talc;
• length - 15 m;
• Width - 1 m;

following table you will find the specifications of other types of roofing:

Using a different composition, manufacturers produce other varieties of roofing material:

1. Toll - consists of slate roofing paper impregnated substrate.
2. Rubemast - tougher type of material, which included a very viscous bitumen.
3. Steklobit - roofing material, manufactured from fiberglass.
4. euroruberoid - consists of a polyester or fiberglass.

Regardless of the type and grade of the material, its quality can be determined by weight.The greater the weight, the more bitumen composition.Accordingly, this roofing material is qualitative.

Roofing felt is widely used on large construction sites and in private households.Installation of the material does not require special knowledge or skills.Therefore, it is in great demand at the roof waterproofing, or the foundation of houses, barns and other outbuildings.Feedback from professional builders and private masters, roofing is the most practical roofing and waterproofing materials.

Benefits

1. low price;
2. availability (available at any hardware store);
3. ease of installation;
4. universality (some species are used as roofing and waterproofing material).

Disadvantages

relatively low strength.Some species, such as roofing felt, have a small lifetime.When waterproofing of underground facilities not protect against groundwater.

Considering all the pros and cons we can conclude that the roofing material is high-grade roofing material is still a lot of time.
