The system has joints similar to traditional stucco. Example of Materials and Workmanship Guarantee and. Weber provides 10 year materials guarantee on all products, a joint materials and workmanship guarantee can also be arranged in conjunction with the installer. These proprietary systems are secured by a system of extruded aluminium rail systems fixed securely to the substrate with insulation material inserted within the void. The systems are classified as class 0 or ‘low risk’ as described in the national Building Regulations. It is breathable, lightweight, environmentally friendly, providing a tight thermal envelope and improved indoor air quality. A steel mesh is then through fixed to provide a more robust system. The aggregate may be any hard stone of an equal graded size to suit the particular application and creates a “lumpy texture” finish. Thornburg, Douglas W., and John R. Henry. Some cheaper variants might result in the loss opacity of surface brightness over a relatively short life span. The supporting wall surface should be continuous (not "open framing") and flat. High quality acrylics can provide a longer term durability, colour stability, and crack resistance compared to polymer cement finishes. To complete the system choose any finish from our contemporary or traditional ranges. Often, a standard EWI system may be all that is required. We”ll take a look at your project, test the substrate and give you our honest opinion. As demonstrated, our systems are highly versatile and can be used to create numerous external wall insulation systems for a range of properties and substrates.

Site Application Guide, full documentation outlining all stages in the installation of the relevant webertherm EWI system for use by installer, main contractors and clerk of works. A very wide selection of light colours are available. There are two main types of insulation board – mineral wool insulation and EPS. If you have any questions or would like assistance... Full specification service, to NBS standards, providing advice on the appropriate system to use, including all necessary components and render finishes. We are the industry experts in EWI and deliver premium products with proven, long-lasting solutions for external wall insulation, ventilated rainscreen and cavity drainage systems. Depending on a variety of site and project specific conditions, EIFS have the potential to save money in construction costs and contribute toward energy efficient operations and environmental responsibility when correctly designed and executed. The brick slips usually have a size of about 210-240 x 50-71 x 20 mm (length x height x width).[3]. ga('send', 'event', 'NAME_OF_FORM', 'submit'); EIFS became very popular in the mid- 1970s due to the oil embargo and the resultant surge in interest in insulating wall systems that conserve energy used for heating and cooling. Sheffield University Student Accommodation. There are so many different names and systems out there that it is easy to get confused. EIFS are in compliance with modern building codes that emphasize energy conservation through the use of CI (continuous insulation) and a continuous air barrier. The technical national consensus standard for the definition of an EIFS, as published by ASTM International does not include flashing or sealants as part of the EIFS. Adhesives and finishes that are cementless harden by the evaporation of water. The most common type of EIFS used today is the system that includes a drainage cavity, which allows any and all moisture to exit the wall. Research, conducted by the Oak Ridge National Laboratory and supported by the Department of Energy, has affirmed that EIFS are the "best performing cladding"[10] in relation to thermal and moisture control when compared to brick, stucco, and cementitious fiberboard siding.
