With the manufactured laminated end product being then mechanically fastened on site there are no issues around extreme heat or cold in the installation process. Being flexible it in fact acts as a shock absorber, compared to most hard fix cements and many epoxies, some of which tend to go brittle under extreme cold conditions. EcoSmart Stone is factory laminated under uniform temperature conditions with flexible polyurethane adhesives which perform under all weather conditions and do not breakdown with constant stress. This eliminates man made mixing errors in conventional mortar mixing. Factory mixed acrylic mortars have since been developed to maintain a more flexible bed for cladding stone. Addition of lime to the mixes aids flexibility but slows the curing, especially in cold conditions. Many mortars also do not have the flexibility to handle stresses of heat and cold expansion. This can be compromised by man-made inaccurate mortar material measurements and/or weather conditions, too hot, too cold or frost. Many stone claddings are applied on site by mortar methods. Waterproof seal all the lining boards after jointing and filling.Īpply the stone cladding with approved adhesive or mortars.ĭelamination is always a question asked of many fixing procedures. Thirdly, EcoSmart Stone utilises up 60% less natural stone resources compared to most other cladding stone.Īssuming a new stud wall building let’s look at the processes involved in most other cladding stone installations…įit battens to allow a cavity to comply with NZ or BCA standards.Ĭover the walls with lining material (fibre cement sheet or other)įill all the joints with mesh and approved filler material. Secondly, most of these methods become a heat and cold sink, allowing heat and cold transfer through to the wall studs. All those extra materials and labour costs money. With EcoSmart Stone the walls are finished and insulated direct over studs, in just one single application, not four, five or six. EcoSmart Stone in many situations can be installed in little more time than just the lining is fixed and prepared, let alone the stone application in other cladding systems. These installations are usually wet fix methods too, which means wet mortar mess. In some cases the stone cladding may be inexpensive, but when all the components and labour are added it becomes expensive. Exclusive of any wall insulation required it adds considerable materials and labour to the stone cladding process. Most other stone claddings require a separate wall fabric to fix the stone to, either fibre cement sheeting or lathe and plaster as in the US/Canada. Assuming even without possible risks of cracking, the ongoing maintenance costs can far exceed the initial cost advantages of EIFS over EcoSmart Stone. Whilst less expensive than EcoSmart Stone the EIFS systems invariably require ongoing painting and maintenance throughout the life of the building. These systems have since been improved with a regulatry drainage cavity. See results of direct fix leaking home syndrome NZ click here. Ventilation of EIFS by way of a cavity is extremely important in these systems as proven by the extensive damage caused by early direct fix methods used in New Zealand. Proper reparation of any monolithic finish almost always requires rectification of the complete wall in order to achieve the seamless finish without noticeable ‘patches’. In the event of movement in an EcoSmart Stone installation, being modular pieces, each joint acts as a movement control joint without affecting the integrity of the finished wall. With this movement something has to give, and as a continuous wall it means potential cracking in the substrate. A continuous wall (monolithic) finish that stands the test of time is always a difficult ask when building structures constantly move with the expansion pressures of heat, cold and moisture.
