Linocrom - pros, types, price and styling

Despite the massive distribution of metal-based roofing, bituminous materials are still relevant.

Bitumen - a rather old technology of roofing, however, during its existence, it managed to gain popularity and find its application. The most common material is linocrome.

Advanced manufacturing technology makes soft roof high quality and resistant to moisture. Linocrom is used both for the repair of old roofs and for the creation of new structures. Its durability and practicality depend on the number of layers.

There is a huge assortment of various modifications of roll roofing on the building materials market. Each type has its own purpose and excludes the possibility of using it in other conditions.

You need to pay attention to the labeling, the basis of the material and other important characteristics. Also, it is worth understanding the intricacies of installation in order to know how important and important this is. The durability of the roofing depends on the fulfillment of all the nuances.

Description and scope

Linocrom - bituminous material of roll type, which is used for roof repair. It is relevant for roofs with a slope level of no more than 10 degrees. The basis for laying linocrome must be firm and thoroughly cleaned. Also, this material acts as a waterproofing agent.

Available with various coatings:

1. Polyester.
2. Fiberglass.
3. Fiberglass.

From above, the material is covered with a special polymer coating.

Linocrom consists of five layers:

1. bottom layer consists of a film that melts easily when exposed to direct flame. It is this factor that determines the installation method.
2. Astringent bitumen-polymer substance covers the base on both sides. These layers help protect the material from decay.
3. The basis is glass woolt, polyester and fiberglass.
4. The top layer defines the brand of the product and its purpose. It also has a protective function and has a coarse-grained structure.

Application area:

1. Roofing.
2. Creation of foundations.
3. Floor protection from moisture.
4. As a waterproofing for swimming pools.
5. For wall insulation basements.
6. Protects from water metal pipelines.

Linocrom can be used in any climatic conditions.

Linocrom is produced by double-sided spraying of a binder on a fiberglass or polyester base. The binder is made from high quality bitumen and a special filler. A protective layer is applied to the surface, which is asbogal or slate. All technology is implemented in rolling mills.

Advantages and disadvantages

The main advantages of soft roofing are:

1. Long service life - 8-10 years old.
2. Waterproof.
3. Made from high quality and durable raw materials.
4. Low cost.
5. Improved heat resistance properties.
6. Ease of installation.
7. Can fit even at sub-zero temperatures.
8. Good noise insulation characteristics.

Linocrom is used for the restoration of roofs of any complexity. The main thing is that the surface is relatively flat. The material will protect the attic from moisture.

It can serve as an external base for an insulating cake. Due to its durable synthetic properties, roofing material does not break or break under mechanical stress and maintenance. To get a good result, it is imperative to follow the basic installation rules.

In addition to the advantages, linocrom also has its disadvantages:

1. At temperatures below -15 degrees, the material begins to crack and deform.
2. If you do not protect the coating from direct sunlight in any wayth, over the years, the service life is significantly reduced. The protective layer begins to melt and expose the binder.

Types and brands

Depending on the brand of linocrome, there are two main types:

1. Lining material.
2. Roofing material.

The two types are used in tandem when installing a new roof. In other situations, the option is chosen that is most suitable for certain conditions.

Linocrome brand is determined by the type of top protective coating.

Distinguish:

1. KS brand - the front and bottom sides of the linocrome are created from a special polymer film with coarse-grained dressing.
2. PS brand - for both sides a film with fine-grained dressing is used. It is used for the lower part of the roofing sheet or acts as a waterproofing agent in the creation of building structures.

Other varieties:

1. Linocrom EKP Is a bitumen roll material, which is laid by means of fusion. The basis of the material is polyester. The protective layer consists of high quality bitumen, which protects the material from the influence of ultraviolet rays. It is an elastic and very flexible flooring. Can be installed as a top layer of a roof. Withstands loads and has a long service life.
2. Linocrom EPP - a waterproofing material based on a polyester fabric. Bitumen with additional additives acts as a binder. A polymer film is fixed on top. Suitable for waterproofing building structures and the bottom of roof decks.
3. Linocrom TKP - a material for roofing purposes, which is light weight and high strength. This is achieved thanks to the basis, consisting of fiberglass. Shows good results when stretched and broken. The upper protective layer consists of mineral dressing. It is used as a top layer of roofing and waterproofing of building structures.
4. Linokrom CCI - roofing material based on bituminous fiberglass. It has high strength and is very difficult to break. Good heat-resistant qualities. When exposed to high temperatures, it does not deform and does not change its performance.
5. Linokrom HKP - roof covering, which is used for the construction of the top layer. It is made of fiberglass and impregnated with coarse-grained dressing. Withstands severe climatic loads and is the best representative of this group.
6. Linocrom HPP - bituminous roofing material with a fiberglass base. It is used for the lower layer of the roof and as a waterproofing pipe, and in the construction of interfloor floors. It has the lowest price, however, it is somewhat heavier than similar counterparts.

Characteristics and cost

Linocrom is supplied in rolls 10 and 15 meters long and 1 meter wide. The material is able to withstand a temperature range of up to 80 degrees.

It is better to store rolls away from heating devices without direct sunlight, observing an upright position.

Properties:

1. Breaking strength - 60-80 kgf.
2. Absolute water absorption.
3. Brittleness of the material rises at temperatures from 15 to 40 degrees.
4. Can withstand temperature stress at 80-100 degrees for two hours.
5. Service life depends on markings, method and operating conditions: the upper roofing material serves no more than 10 years, the lower one - about 20.
6. Weight 1 sq.m approx.3.6 - 4.6 kg.

Material prices vary from 60 to 150 rubles per roll. The most expensive is the EPP coating, which is based on polyester. The cheapest is the TPP linocrome with a fiberglass base. The cost depends on the protective layer, the thickness of the material and the base used.

Styling

Before laying the roofing, it is necessary to carry out a number of preparatory work:

1. Topical application of soft roofing, will be in case the roof has an insignificant angle of inclination.
2. For better fusion, the roof surface is thoroughly cleaned of dirt, foreign objects and leaves.
3. The base is treated with a bituminous primer, which bridges small cracks, seams and fractures. It is a viscous primer that, when it gets into voids, binds dust and provides better adhesion. Apply the primer with a roller or brush.

Required tools:

• linocrome;
• gas-burner;
• a tool for unwinding a roll - a hook;

Step by step guide:

1. Step one. In order to properly lay the material, use a gas burner. It helps to effectively warm up the base and the canvas itself. Before heating, the canvas is aligned along the length of the roof perpendicular to the parapet or cornice. Correct alignment helps determine the exact seam line. After adjustment, the roll is rolled again, which must be done with extreme caution. Note that an offset of 1 cm at the very beginning will translate into 10 cm at the end of the fusion. Before installing the roof, the surface is thoroughly warmed up to avoid the possibility of air gaps.
2. Step two. The beginning of the bale is heated and rolled. The fusion of the material occurs according to the principle of unwinding, moving backwards. After heating, the linocrome is pressed against the roof and the joints are heated to create the necessary tightness. The overlap is done at 8-10 cm.
3. Step three. All rolls must be guided continuously to avoid further leakage problems.

Advice

1. For linokrom to maximize its performance, it should only be used on a hard surface.
2. As a roofing material no need to buy a polyester-based linocrome. Due to the low elasticity and possible oxidation of bitumen, the roof can collapse in a short time.
3. In order to save, it is better to combine grades of TPP and HKP, as a result, the strength of the roof will be increased.
4. When laying two layers of material, it is impossible for the seams to match.
5. Protruding reliefs pasted over by hand.
6. Do not step on only molten material.
7. In the case of the old roof, before fusing the linocrome, it is necessary to restore the previous coating.
