Full-sized Vacuum-sealed Insulating Glazing (VIG)Windows for Residential Applications
The current state-of-the-art of the vacuum insulation glazing (VIG) technology and assessed the technical feasibility,thermal and heat transfer assessments of various components for assembly and manufacturing of VIG windows have been revieved.The focus of this paper is to present how best VIG can be assembled in the whole window configuration that can provide minimum possible U-value without drastically affecting the vision area.Using detailed thermal and 2-dimensional heat transfer models,evaluated the relative impacts of various framing materials,size and dimensions for VIG and other assembly components to design VIG windows.The review of the current state of VIG technologies identified a number of potential options for window manufacturers and clearly identified minimum specifications that can achieve lower than 0.7 W/(m2 · K) windows.For example,thermal and 2D heat transfer analyses provided the required overlap of at least 55 mm,about 40 mm more than conventional,for framing components with the VIG to improve edge U-value.The industry partner working with the project team developed three test sample VIG windows incorporating the above study parameters.The measured thermal performance results confirmed that it is feasible to integrate VIG in the residential size windows that show excellent thermal performance This study confirms the commercial viability of VIG window manufacturing for the cost-sensitive housing and building markets in North America.
