Data analytics tool for peel resistance of tapes based on peel test curves and tape membrane tension tests

This publication is a web app source code developed for project TightEN: Durable adhesive airtight solutions for energy efficient building envelopes, funded by The Research COuncil of Norway, grant number: 294894. The project Durable Adhesive Airtight Solutions for Energy Efficient Building Envelopes (TightEN) addresses the need for ensuring a satisfactory long-term airtightness of adhesive solutions so that new and renovated buildings will remain energy efficient throughout their lifetime. Airtight building envelopes are essential for energy-efficient buildings, and as the requirements for airtightness have increased, adhesive solutions have become necessary to obtain and secure a high airtightness performance. To date, there is little knowledge on the durability of the adhesive products available, especially in Nordic climate. A deterioration of the airtightness system will lead to increased heat loss and thereby undermine energy efficiency over the years. This data analytics tool in the form of an easily accessible web app combines the results of several long testing campaigns in a concise and versatile form. Source codes are available and data are coded for necessary protection and anonimity of producers. Thus, the open science principle of as open as possible and as close as necessary is retained. Web app is based on the peel test and tension test results for tapes on different substrates and tape membranes respectively. Several methods, i.e. principal component analysis, linear regression, polynomial curve fitting, statistical analysis, as well as different visualization techniques were applied for data presentation.
