Isover insulation density for ventilated facades. Izover stucco facade: all about insulation. General information about the plaster facade

The plaster facade of the Isover company is very popular among many professionals in the field of insulation. This insulation technology, where the Isover plaster facade is used, is used everywhere, and it has more than proven itself well.

A huge advantage is that the plaster facade of this company can be used for private buildings, and for huge industrial buildings or extensive water supply systems.

It is noteworthy that the manufacturer of this product began its work 350 years ago, and still its insulation technology remains the most preferred all over the world.

1 General information about the plaster facade

The stucco facade of the Isover company is even unique in a sense. If you look at it, the most serious problem of mineral wool, which is used as a facade insulation, is that the density of the material is low and it is soft, prone to deformation.

It turns out that there is little point in facing the facade with this insulation, because even with a normal touch it deforms quite strongly (by the standards of the requirements for facade insulation).

It was not easy for Isover to solve this problem, but it still worked out. At the exit, we have a plaster facade made on the basis of the same mineral wool, but now it can be used even without the need for external cladding, unlike.

The technical characteristics of this product are impressive, and you should familiarize yourself with them:

• The coefficient of thermal conductivity, which is so important for heaters, is not more than 0.038 W / (m * K), which is an excellent indicator;
• The potential period of accident-free operation exceeds the mark of twenty-five years;
• The linear dimensions of the insulation boards do not change in any way with possible temperature fluctuations, as well as with seasonal changes in humidity;
• Excellent vapor permeability;
• The material from which this product is made does not burn;
• The dimensions of the insulation boards are 60 × 120 centimeters, and their thickness is in the range from 50 to 200 millimeters. Ideal for .

As it can be replaced, the characteristics of this product are much better than those of the closest analogues.

2 Mounting process

The manufacturer's installation instructions for this material are as follows:

• Before making a sticker, the insulation boards are primed. For a primer, a thin layer of the same material is selected, with which the cladding will later be attached to the facade of the building;
• The surface with which the insulation board is fixed to the wall must be no less than forty percent of its area;
• Vertical seams in all cases should be offset relative to the bottom tile row in all subsequent rows.

2.1 ventilated front bottom

Izover VENTFASAD BOTTOM type "mono" is intended only for use as an inner layer of insulating material and only when laying two-layer insulating insulation.

These "mono" type insulation boards do not need much rigidity, since, in fact, they are only a filler for the cavity located under the outer layer, whose direct function is only to ensure maximum heat retention.

The specifications and description of this mono type product are as follows:

• The material belongs to the class and type of non-combustible products as;
• Due to the increased elasticity and elasticity in this material of the "mono" type, the appearance of air pockets is excluded;
• Dimensions of the product VENTIFACAD BOTTOM of the "mono" type are 610 × 1170 mm, and its thickness is 50-10-150 mm.

2.2 VENT FACADE TOP

Unlike the previous product, this insulation is represented by an outer layer for an exclusively two-layer insulation method. The properties of this material are as follows:

• Due to the relatively low coefficient of permeability for air masses and heat, this product guarantees effective and stable protection against heat leakage from the structure;
• According to factory standards, the material has the "NG" group, that is, it belongs to non-combustible materials. However, it is possible to order a product with a layer of special fiberglass. Then the product will belong to the group "G1".

• The degree of rigidity of the average parameters;
• Product dimensions are 610×1170 mm or 1200×1600 mm, with thickness ranges from 50 to 120 mm.

2.4 Instructions for insulation from the manufacturer (video)

The facade of the building is open to all winds and thunderstorms. He, like the roof, needs enhanced protection.
Isover has developed the VentFacade system, which includes two layers of insulation. Consider the outer layer of insulation - VentFacade Top.

Izover VentFacade Top - rigid plates that are made of fiberglass. Products can be produced without additional coating or with it (VentFacade Top/Ch - boards laminated with black fiberglass).
The use of a black coating makes it possible to exclude the installation of diffuse windproof membranes and allows the use of thermal insulation in light penetrating structures.

Benefits of installing a suspended ventilation facade

• Helps to quickly remove moisture from the outer wall.
• Protects load-bearing walls from precipitation and temperature amplitude of the air.
• Provides a low level of heat transfer due to the dense structure, the absence of air "pockets" and a tight tongue-and-groove connection.
• Reduces the load on the wall of the building due to its low dead weight.

Application

Izover VentFacade Top slabs are used to provide windproof functions in the insulation complex and as a top coating of two-layer insulation in systems of suspended ventilation facades. Installation of insulation VentFacade Top is carried out with the help of fixing elements.
Another type of VentFacade Top slab is a laminated product called Izover VentFacade Top/Ch. It performs the functions of wind, hydro, thermal insulation. It is laid as the top layer in the ventilation facade system. Additionally, VentFacade-Top/Ch can be used to create a windproof layer in sandwich panels with a staged assembly.

Isover mineral wool is a product of one of the world's leading manufacturers of basalt slabs and other mineral wool insulation and glass fiber insulation materials. Heaters of this brand have established themselves as products that are distinguished by the optimal combination of price, quality and excellent performance.

Application area

Thermal insulation materials produced by the French company Saint-Gobain, in addition to excellent insulation functions, also have very significant noise-absorbing abilities, which significantly expands their scope.

Isover mineral wool slabs are widely used both in the field of industrial construction for the purpose of insulating interfloor ceilings and voids inside hollow walls, and for household thermal insulation of residential buildings and premises.

According to consumer feedback, Isover insulation materials in a practical aspect perform better than similar products manufactured by other competing manufacturers.

Mineral wool insulation brand Isover allow you to produce thermal insulation of any surface. The company produces products that make it possible to insulate both internal and external wall surfaces, insulate attic floors, pitched and straight roof ceilings.

Significant advantages of heat-insulating mineral wool boards of the French brand are their characteristics such as mechanical flexibility, resistance to deformation effects and tensile strength. This makes it possible to use them on structures of a complex geometric profile such as pipes, industrial equipment, structural elements of production lines, and others.

As noted above, Isover mineral wool also has very high technical soundproofing performance, successfully protecting industrial premises and rooms in apartment buildings from any external noise.

Varieties

This brand produces a very wide range of mineral wool insulation, which differ in their functional purpose. The company's products are divided into two categories. The first includes insulation intended for industrial use, and the second includes mineral wool boards for domestic use, including those that can be laid indoors.

Isover "Venti"

For ventilated facades, a brand of insulation called Isover "Venti" can be distinguished. It is a slab mineral wool insulation with very solid technical characteristics., significantly exceeding such indicators for ordinary mineral wool. Thus, the density of "Venti" is 88 kg / m3, and its compressive strength is 20 kPa with a perpendicular tension value of 4 kPa.

The thermal insulation coefficient of this material has an index of the order of 0.035 W / mk, and the degree of its vapor permeability is 0.3 mg / MPa. When immersed in water for a day, the degree of water absorption of this material does not exceed 1% of its total mass. It belongs to the fire resistance class NG.

"VentFacade Mono"

Belongs to the class of heat-insulating, sound-absorbing materials based on fiberglass, designed to create the main heat-insulating layer for single-layer thermal insulation. The device of ventilated facades in buildings based on this material is carried out without restrictions on their height.

The form of release of this brand are plates, convenient for installation. Their thickness is 50 and 100 mm with total sheet dimensions of 1190 mm × 1380 mm.

Plates "VentFacade Mono" have a low coefficient of thermal conductivity and a high degree of air permeability, that is, they are a "breathable" material. However, their high density makes it possible to avoid heat losses due to convective heat transfer.

This material is completely non-combustible, chemically neutral, does not decompose under the influence of biological factors, is resistant to fungus and mold, does not contain compounds harmful to humans. At the same time, this material, due to its high elasticity, does not shrink, retaining its original volume throughout the entire period of operation.

"VentFacade Bottom"

The next type of Isover products are heat-insulating elements "VentFacade Bottom". They are intended for use as an inner layer of insulation and are used only for laying a two-layer insulating insulating material. The basis of such plates is fiberglass. Due to their production from natural ingredients such as sand, soda and limestone, the content of synthetic binders in them is minimal.

These plates are of the "mono" type, and they do not require high rigidity and density, because they inherently serve to fill the cavity under the outer layer, which, in fact, performs the function of keeping warm. This non-combustible insulation material is characterized by increased elasticity and elasticity, so that air pockets do not appear in its volume.

These slabs can be used as a single-layer thermal insulation included in the facade ventilated systems with an air gap on balconies and loggias and on external frame walls. The material fits snugly to the base and can be attached to it with one dowel.

In order for the structures of ventilated facades and the building as a whole to meet modern thermal protection standards, it is necessary to use heat-insulating materials that ensure high thermal efficiency of the structure and fire safety of the system.

Mineral wool ISOVER Vent Facade meets the requirements.

Single layer insulation: used for small design thicknesses of thermal insulation, especially for the reconstruction and repair of facades.

For this application is used:

• ISOVER Vent Facade Mono
• ISOVER Vent Facade Optima

The use of these materials provides maximum thermal protection of the building due to the low coefficient of thermal conductivity.

Double layer insulation: most common in new construction, consists of two layers of thermal insulation: internal and external.

• The inner layer is the main thermal insulation layer. Mineral wool ISOVER Vent Facade Bottom/ISOVER Vent Facade Bottom Light/ISOVER Vent Facade Optima provides a tight fit to the insulated structure due to its resilience and elasticity.
• The outer layer acts as a windscreen. Optimal dimensions of the material ISOVER Vent Facade Top make it possible to overlap the joints of the plates of the inner layer, which ensures the absence of "cold bridges".

The combined use of ISOVER Vent Facade Top and ISOVER Vent Facade Bottom is distinguished by high thermal performance, unlike other insulation options for NVF.

Composition and properties of insulation Izover VentFacade-Top

VentFacade Top are dense, rigid mats made of fiberglass. Mats can be used both with and without an additional layer, because. the material is laminated with dark glass.

Due to the black layer of fiberglass, Izover VentFacade Top insulation can be successfully used when installed in translucent structures, without installing windproof and diffuse membranes.

An additional convenient function of the VentFacade-Top insulation is that it can be used in sandwich panels as a layer that protects against wind. The functions of this material include heat, hydro, wind insulation.

Insulation mats Izover VentFacade-Top are mounted from above in a two-layer facade system. Then they will not only keep the heat inside, but also ensure the stability of the building to adverse environmental factors: wind, precipitation, dust, dirt, fog, smog.

• Foundation (bearing wall): concrete, foam concrete, brick, other building blocks.
• The substructure is the supporting element of the ventilated façade system.
• The heat-insulating layer consists of two layers, which are mounted with overlapping joints: ISOVER VentFacade Top and ISOVER VentFacade Bottom.
• Dish-shaped dowel as a fastener for insulation mats.
• Vent hole. Its value is set according to the design of the building and the purpose of the premises.
• Cladding panel. These are materials that protect the structure from the outside from environmental influences. They give an attractive appearance to the building.

It is important during installation to monitor the thickness of the insulation. It should be the same throughout the treated area. This will make the thermal resistance of the enclosing structural elements the most efficient and reliable.

To avoid unwanted distortions and violations of the installation of heat-insulating mats, you should contact professional builders and exercise control. The choice of fasteners also affects the quality of installation. Do not save and buy low-quality dowels.

Installation of Izover VentFacade mats is carried out close to each other so that there are no even minimal voids between the plates. If this fails, then empty seams must be filled with the same material. A gap smaller than 2 mm can be left empty without affecting the thermal insulation. Insulating corners by bending heat-insulating mats is prohibited. The corners should be insulated with dressing of each layer, maintaining the geometry of the facade. You can calculate the consumption of hardware based on the rule that 2-3 dish-shaped dowels go to the bottom layer of mats, 4-5 pieces to the top.
