Impact of the imperfection of thermal insulation on structural changes of thin-layer façade claddings in ETICS

Size effect of bonded area for bonded joints between ETICS with an acrylic thin-film plaster and sheet metal component

“…Results of tensile adhesion σadh (in MPa) and force F (in N), standard deviation sx (in MPa for σadh, in % for ε) and coefficient of variation vx (in %) when acting on different areas. 1 The average values are a summary of six measurements conducted for each tested combination.…”

“…In these times of energy crisis, more and more attention is being paid to the energy self-sufficiency of buildings and one of the ways to achieve this goal is to insulate them. In practice, this insulation is most often done with ETICS systems with 200 mm thick thermal insulation [1,2] And the anchoring of plumbing elements into these insulation systems is highly inappropriate due to the perforation of the system and possible water seepage. Previous research has already shown that glued joints are a very suitable alternative for fastening through the thermal insulation system to the substrate and shows its high load-bearing capacity which exceeds the load-bearing capacity of the plaster guaranteed by the manufacturer [3].…”

Research of Heat Tolerance and Moisture Conditions of New Worked-Out Face Structures with Complete Gap Spacings

“…An analysis of the results given in Table 4 shows that the insulation is significantly waterlogged in faces with closed gap spacings. This is a known weakness of extruded polystyrene foam [40,41]. The use of air channels in the protection fence scheme made it possible to avoid the waterlogging of the insulation, significantly reducing the accumulation of moisture.…”

Use of Bonded Joints for Fastening Sheet-Metal Components to Contemporary Facades Fitted with an External Thermal Insulation Composite System with Thin-Layer Acrylic Plaster

“…The first is the use of suspended facade systems, which consist of a load-bearing (usually aluminium) structure, mineral wool thermal insulation, a windproof diffusion-open membrane, a ventilated air gap and a facing cladding board [4,5]. The second option is external thermal insulation using a composite system that is in full contact with the original surface of the facade and consists of thermal insulation (most often expanded polystyrene or mineral wool, or other materials that are used less frequently) and reinforcing layers of cement screed with fibreglass mesh, coloured primer and coloured thin-layer plaster [6,7]. Both options include a thick layer of thermal insulation that can be sized as required to provide the desired energy savings.…”
