Ventfasad own hands: how to protect and transform the house

Ventfasad - a system that is increasingly used for decoration and additional thermal insulation of the house. Consider its features and variations, as well as details of mounting on the participants' experience FORUMHOUSE

Depending on what material is constructed or built the house, sooner or later, every owner has to think about the facade decoration. Ventilated facade is now a very popular system, which protects the walls from outside influences, and increases the energy efficiency of homes and radically change its appearance. Ventfasada device options are many, but they are all derivative of the underlying technology, worthy of detailed consideration.

Ventilated facade - system device

Ventilated facade - a versatile multi-layer insulation system walling mandatory ventilation gap of 30-50 mm for the unimpeded air flow in the direction down up. Due to the ventilation gap from the wall of the "pie" removes water vapor formed in each dwelling house. In other words, Ventfasad not only protects the wall from the aggressive environment, but also provides an optimal moisture conditions, threading service life of the structure.

ventilated facade system usually consists of the following layers:

• subsystem;
• teloizolyatsiya;
• gidrovetrozaschitnaya membrane;
• ventilation gap;
• decorative facing screen.

As the insulation commonly used in ventfasada plate stone woolBecause this material combines with minimum thermal conductivity of hydrophobic, non-flammability and lack of shrinkage. Passing through the fiber pairs falls on the outer surface of the plates in the form of condensate and erode - isolation is maintained in the dry state and does not lose heat-qualities. It attracts and easy installation - vraspor without additional fixation by mechanical or adhesive means. ventfasada system includes a membrane that covers the insulation against wind and moisture, but it confuses many of its flammability.

Insulate a house from concrete blocks of ventfasada technology insulation (in two layers, 50 plus 100 mm), and a ground ventzazor siding. Confuses gidrovetrozaschity organization - at least the top layer of insulation and 90 kg / m³ density but I doubt its hydrophobic properties. Combustible film is put do not want to, and non-flammable bite at an issue price at the facade of an area of ​​about 300 m². Why not to mix in technology from the wet facade, covering the mineral wool diluted to the consistency of liquid plaster / thin layer of solution (roll)? Smartkalk with this plaster cake and 3-4 mm for all solutions, even DSP gives ventzazore dew point. From the wind in addition, IMHO, protection, water - too. Cracks, even if they are under ventfasada invisible. Are there any pitfalls? How to live a solution ventfasada? What is mistaken?

You can do without a plaster layer.

insulation manufacturers are allowed not to install membrane over insulation on ventfasada. And we agree designers. And customers who are able to listen to the arguments.

• At low objects thrust into ventzazore minimum, so the fiber blow-heater will not.
• This thrust is sufficient to remove the moisture from the insulation. In normally made facade screen closes the water flow. It just should not be. And almost always moisture condensation.
• Solid facade screen, in addition to porcelain on capping, he is a good wind protection. And restrains direct air pressure on the side of the building.

This is what we always write the designers with a request to renegotiate the facade of the pie by removing gidrovetrozaschitnuyu membrane. And they do it.

If the circuit is permeable to all sorts of "neighbors", without protection can cause problems.

Without the film I very spoiled bird heater, so I had to install. And the difference is not noticed.

When the membrane is critical flammability and Ventfasad closed circuit (soffits, grating / grid), then in a private home can do without protection, though this layer is present in a typical form factor.

Ventfasada demand both in the decoration of public buildings, including multi-storey and private buildings up to three floors. This is due to variability, since the functional characteristics of the system and dependent on the layout and visual variety makes it possible to fit in any design. Restriction may be state grounds - when talking about the reconstruction of the house with a solid "experience" and dilapidated walls, facade system must be lightweight. This is not a reason to abandon ventfasada in principle, but will most accurately calculate all load and pick the appropriate subsystem hardware and lining.

Variety of subsystems for ventilated facade

The subsystem is a support frame, preferably of vertical guides (profiles), which is mounted facing. Also subsystem includes nodes framing of door and window openings and corner elements. When laying a two-layer insulation subsystem assembled also kontrobreshetkoy. Subsystems are metal and wood, at least - combined.

Metal subsystem resistant to the environment - of aluminum, stainless or galvanized steel; Profiles are mounted as close to the walls and at a distance, by means of brackets. In the first case the spacing between the guide plates is adjusted for the width of the heater (60 cm), which are stacked therebetween vraspor without further mechanical fixing. The second - the distance between the guides depends on the type of lining (weight, dimensions). Subsystems of aluminum and stainless steel is more expensive, but more durable than the budget option of galvanizing. Metal subsystem required on high-rise buildings, and in cases where, as the lining of a private house planned granite.

Wooden subsystem - of the timber, for protection from the environment the wood is impregnated by specialized formulations (retardants, biosecurity, or one impregnation with a combined action). The guides are mounted flush with the wall. Wood affordable and sturdy enough, so the bulk of ventfasadov at private homes is going to such a subsystem. Subject to the technology installation excess moisture is removed through timely ventzazor and within the system there are no conditions for the development of rot or mildew. And from direct exposure to rain frame protects the lining.

frameless Ventfasad

As not every curtain facade is ventilated, and not everyone ventilated facade - curtain, there is a kind of frameless. It's about a brick-ventilated facade - the house from any non-flammable wall material insulation and insulated obkladyvayut facing brick through the ventilation gap, latching flexible links or metal brackets. Brick Ventfasad erected in two ways:

• during the construction phase of the box - by pouring the foundation made in view of the multilayer wall thickness;
• operated around the house - if there is no opportunity to build brick screen on the foundation under it is cast further, rarely rely on metal subsystem.

Variations in the wall of the pie more.

Approaching the process thoroughly, I would recommend to consider several options for facade solutions for the case of the outer cover layer:

• ceramic block 440-500 mm, 30-40 mm air gap, facing brick 85-120 mm;
• brick 380 mm, insulation (mineral wool or foamed glass), an air gap of 30-40 mm and 85-120 mm ceramic bricks;
• GDI (silicate blocks) 375-400 mm, the air gap of 30-40 mm, face brick 85-120 mm.

The particular solutions determined by the complexity of the facade and the requirements to the materials (ceramics, GSB, relative to the insulation and m. P.).

Facing a ventilated facade

As a ventilated facade cladding on can be practically any material can be restricted only low bearing capacity ground. In this case, allowed only light materials. Ventfsad usually veneer:

• siding - vinyl, acrylic, metal, fiber cement, ground panels of these groups;
• plates - preferably SIR and DSPs with pointing decorative elements under timbered or with further flexible cladding the facade tile or brick flexible;
• tiles - most concreteWith integrated fixing elements for fixing on the subsystem;
• granite - on the subsystem and clamps;
• wood - paneling, plankenom, thermo, and cut Unedged board, Imitation lumber and others.

Concrete paving, which imitates the texture of natural stone or brick, facade allows transform from any of the wall material. And thanks to the ventilation gap it can be used even by the vapor-permeable protective structures, as moisture will be eroding, but not close to the wall.

Six months ago, I insulate your house and stoned concrete tiles under rock, on the corners of the texture of crushed stone. Efflorescence no, it does not rattle, do not fall off. Wooden lathing.

ventfasada Mount Technology

Ventilated facade mounted in several stages.

Training - is removed from the walls and hinged decorative elements, the substrate must be clean, smooth (as far as possible to bring the plane subsystem) without loose fragments. Wooden walls necessarily treated with antiseptic, stone, Primers, deep penetration with water-repellent properties.

Installation of the subsystem. subsystem parameters depend on the type of insulation and the number of layers; Guides are mounted on screws, dowels, nails, brackets, or other fasteners, based on the characteristics of a base. All wooden elements subsystem necessarily treated ognebiozaschitoy. If necessary, top stuffed kontrobreshetka subsystem.

Warming. When laying vraspor rockwool between the guide does not require additional fixing at mounting directly on a wall attached mechanically to the plastic dowels "fungi". Regardless of the type of wall material, under no insulation membranes and films do not fit.

Gidrovetrozaschita. Stone wool of density 90 kg / m³ needs no protective membrane, a loose thermal insulation it is recommended to close against water and wind. If the screen is permeable facing (granite, wood, slot method), close any insulation, regardless of density.

Facing. Fixation on the subsystem is carried out according to manufacturer's instructions, usually fixing screws with backlash in the pot, but it is possible and an outdoor fixture followed by plaster and shaded hats.

Bruce I cut myself out of the board 50 mm Hand circular saw with a start 70 mm disc impregnated with the first beams - vertical corner. Further, it is pressed against the clamps next through a spacer (a piece of the same lumber length 590 mm), clamp the arm is long, 2 - 3 pieces on the wall 5 m high. Then zasverlivayus punch through timber in the HEC, trying to get between the top unit and the horizontal seam. Only the fastening element, which I was able to pick up the timber for mounting on HEC - metal frame anchor (120 mm approx). Everything else or does not hold, or prohibitively expensive.

Preparedness first row lays batten insulation, fix a light polypropylene tape, a stapler (bay bought 3,000 m), in order not blown away - I work alone. The next series up at major yellow screws, drill bit made of different diameters, so that through the outer timber screw passing freely. I repeat all the operations. Then vetrovlagozaschitnaya membrane vertical lathing of boards 30 mm increments, installation convenient for OSB.

On the OSB will be flexible exterior tiles, imitating brick - Ventfasad dynamic foundation, and this elastic material capable of withstanding deformation without some damage to tightness and appearance species. Such examples are already on our website.

Ventilated facade - one of the most popular thermal insulation systems, valued for versatility, decorative and the ability to self-fulfillment.

If you do not want to deal with an additional facade work, but the priority of energy efficiency - it is worth considering as a wall material TEPLOBLOK, they can do on their own and. Another interesting technology for the brave and skillful - home-made concrete blocks TISE. In the video - a Victorian home of the CIP with ventilated facade.
