Exterior Insulation& Finish System (EIFS)
EIFS is an Acronym that stands for exterior insulation and finish system. It is a non-load bearing, composite cladding system that consists of a weather resistant barrier (Air and/or vapour barrier); An insulation board attached either adhesively, mechanically, or both, to the substrate an integrally reinforced base coat; and a textured protective finish coat
Characteristics and benefits
◉ Energy Efficiency
High
R-Value
The popularity of EIFS comes from its insulating qualities to reduce thermal loads on the exterior building wall and the light weight, low cost, and the ability of the system to be sculpted into shapes and patterns to achieve different aesthetic effects. The thermal performance of the exterior insulation is based on the thickness of the insulation selected.
Drain
The EPS expanded polystyrene rigid panel is the insulation component of the wall systems. The panel possesses the advantage of being geometrically designed at the back with 10mm channels to permit drainage. This innovative design allows for better moisture management without compromising the insulation value of the panel.
No thermal bridges
Insulation fastened to the exterior of the building is much more effective than the same amount located within the stud cavity (batt insulation). By wrapping the building in a seamless ‘blanket’ of insulation, the EIFS bridges the studs of the open wall construction and significantly reduces the amount of energy (cooling or heating) that is allowed to escape. Additionally, at NextGen we incorporate the use of adhesive to fasten the insulation to the assembly. By eliminating the use of mechanical fasteners, you prevent perforations of the system; a potential cause of energy loss. As a result, the building becomes more energy efficient with lower operating costs.
Continuous Membrane
The weather resistant barrier applied directly over the sheathing/substrate is a key element in enhancing the energy efficiency of the insulation. This secondary barrier may be vapour permeable (breathable) or it may be a vapour retarder (non-breathable) depending upon wall performance requirements. Moreover, a self-adhering waterproof tape is used to seal window and door openings, over expansion joints and where dissimilar substrates meet. All these elements seal the envelope and thus prevent air infiltrations.
Shapes & Mouldings
The EPS insulation board used in EIFS can be grooved, moulded, and shaped into a near endless variety of designs. Cornice details, battens, quoins, and window trims can all be manufactured out of EPS insulation and incorporated directly into an EIFS assembly. The dramatically increases the building’s aesthetic value while reducing costs, installation time, and the total weight of the façade.
Colours
Finish coats are available in an unlimited range of colours and in a wide variety of textures. Aside from 300 standard colours, custom matching is also available. This allows building owners to choose specific corporate colours, in unique one-of-a-kind colours for their projects. The design possibilities are endless.
Textures
Our finishes are characterized by the richness of textures we offer. Whether you are looking for a contemporary or classic look, these textures will meet all your design and style ambitions.
Joints & Caulking
Joint sealants are used to seal joints and openings (gaps) between two or more substrates, and are a critical component for building design and construction. The main purpose of sealants is to prevent air, water, and other environmental elements from entering or exiting a structure while permitting limited movement of the substrates.
