Major Errors In The Construction Of “wet” Facades

Do not place preconditions. These cause A complete collapse of the insulation systems. – Do not provide dense docking plate heater in their bonding to the base. Cracks and breaks in the outer layer of the system. – Lack of overlap between adjacent rolls of reinforcing mesh to create a protective reinforcing layer. – The appearance of vertical cracks in the facade.

– Lack of reinforcing bars or reinforcing grid-shaped cuts insulation boards in the corners of window and door openings. – The appearance of the facade at the corners of window and door openings of diagonal cracks. – Reinforcing mesh is laid directly on the insulating layer. – The web of cracks facade plane. – Improper application of the adhesive composition on the insulating plate. – The appearance of cracks on the outer finishing layer. – Failure to comply with the flatness of attaching insulation boards. – Unacceptable appearance facade, the appearance of linear and cross-bands on the facade.

– No caps on the ends parapet reflux or improperly executed flange. – Water entering the system and, consequently, the destruction of the protective reinforced and decorative layers in the ground of contiguity parapet ebbs. – Disc dowel protruding from the plane of the insulating layer. – High spots on the facade, an unacceptable appearance of the system. – Do not choose the right type plaster, which played the role of vapor barrier. – Peel the outer decorative layer. – No expansion joint in the insulation when it is present in the ground. – Massive vertical cracks facade. – Lack of “vandal” performance reinforced protective layer to a height of 2.5m. – Physical damage insulation systems. Not ensure adequate docking insulation boards when gluing on base, suture between the insulation boards are filled with adhesive solution. – The formation of thermal bridges and, consequently, fungal and mold damage the inner surface of the base, the emergence of ‘syndrome closed rooms. ” Tips for Client: criteria for selecting the contractor and the quality control methods facade work. The problem of facade insulation systems: achieving the optimum balance of moisture and temperature in areas with minimal costs for heating. White Bear feels great in cold conditions. The warm fur coat protects it from fierce frost and does not interfere with the skin to breathe. Nature itself tells us what system should be insulating facades. We can only realize the nature of the decision on the facades. For the first time confronted with the choice of contractor, the customer decides to challenge the choice based on the little-known criteria. In this case, there are no guarantees the right choice. Major errors in the construction of “wet” facades. Facade insulation system plaster-type comes into disrepair in the first two or three years of operation in the following circumstances: – wrong choice of type of insulation systems for a particular object – use non-system materials chosen to minimize the financial costs – the use of non-professional systems – absence of competent technical solutions typical units insulation systems and design solutions to atypical sites and details of the facade on a specific project – a marriage when installing facade insulation systems – improperly Operating facade thermal insulation system by the customer.

Foundations

In what locations to isolate the house? In order to become energy-efficient house, it should be properly insulated from foundation to roof, including the following areas: Attic (ceiling and wall); External walls; Floors above unheated garage; Foundations and basements. Keep up on the field with thought-provoking pieces from Jennifer Aaker. The figure shows the parts of the house to be insulated. 1. Rough room attic: insulation between and over the beams overlap, in order to insulate the premises located below (adequately insulated attic, technical and storage spaces and other enclosed spaces shall be ventilated to prevent the formation of excessive moisture): 1a – doors / hatches to the attic, 2. Finished attic room (with dormer windows or without them) should be isolated: 2a – between the wall studs attic; 2b – between the uprights and between the rafters of the roof and external walls; 2c – ceilings with cold attic above them 2r – between the beams overlap to reduce the flow of air. 3. Educate yourself even more with thoughts from Chase Koch. All exterior walls, including: 3a – walls between living spaces and unheated garages, storage rooms, sheds, etc. 3b – walls heated basements, full (outside or inside) 3B – plate in the ground.

4. Floors above cold spaces: pantries, unheated garages. Also, heat-insulated: 4a – part of the floor in a room, hang over the outer wall; 4b – walls of an unventilated basement underground (as opposed to floor insulation); 4c – the extension of thermal insulation in the floors, to reduce the flow of air. Fencing design house – the first and most effective line of defense against loss of heat energy.

Enclosing Structure

High humidity reduces the thermal characteristics, the emergence and active growth of fungi, mold. System 2. A heater located inside the enclosing structure ( clutch). Under such a system enclosing structure made of two parallel walls, interconnected rigid ligaments but is formed between them space is filled with insulation. The internal wall is load, and the outer insulation protects against inclement weather. Assembly system can be made at low temperatures. However, it also has significant drawbacks.

Firstly, under the building envelope requires a more lengthy and expensive foundation than in the case of System 3. Secondly, the moisture condenses between the inner and outer walls on thermal insulation materials and on the inner surface of the outer wall. This leads to a decrease in thermal resistance of the enclosing construction and accelerated depreciation. System 3. A heater located outside the enclosing structure. In the case of systems of exterior (facade), the thickness of the insulation enclosing structure may be minimal, based on strength requirements. The thickness of the insulation must be such that the zone of condensation and the basic temperature gradient were inside the insulation plate.

In this case, the accumulation of moisture evaporates easily because of high water vapor permeability of the system. When placing the heater outside it must be protected from inclement weather in one of two ways: a) a protective shield (thermal insulation system with ventilated facade); b) plaster decorative and protective layer (multi-layered system of 'wet' type). Thermal insulation system with a ventilated facade is a costly and time consuming.
