Comparison of accelerated climate ageing methods of polymer building materials by attenuated total reflectance Fourier transform infrared radiation spectroscopy

Abstract

The degradation of the polymer building materials polypropylene (PP) and high density polyethylene (HDPE) intended for application as water barriers/repellants around building foundation walls have been studied. The PP and HDPE samples have been subjected to various accelerated climate ageing methods for comparison, including exposure to ultraviolet and infrared radiation, heated air, water spray and freezing. The climate ageing processes have been qualitatively and quantitatively investigated by attenuated total reflectance (ATR) Fourier transform infrared (FTIR) radiation spectroscopy.

Vacuum insulation panels for building applications: A review and beyond

“…These climate factors may be divided into ultraviolet, visible and near infrared solar radiation, ambient infrared heat radiation, temperature changes or freezing/thawing cycles, water (e.g. moisture, relative air humidity, rain and wind-driven rain), wind, erosion, pollutions, micro-organisms, oxygen and time determining the effect for all the previous mentioned factors to work [57]. The ageing factors on polymer degradation for VIP envelopes are expressed by Thorsell [58], divided in four main groups: The chemical environment, thermal shocks, ultraviolet light and high energy radiation.…”

Solar radiation glazing factors for window panes, glass structures and electrochromic windows in buildings—Measurement and calculation

“…ultraviolet (UV) radiation (see e.g. our earlier work in , Jelle and Nilsen 2011, Jelle et al 2012c, Jelle 2012. A substantial part of the UV radiation is blocked by the glass itself, but nevertheless a significant amount of UV radiation passes through the glass and into the buildings.…”

Robustness classification of materials, assemblies and buildings

“…Based on these statistics regarding the impact of water alone, it is evident that evaluations of a building's robustness to different climate factors are of great importance. Table 2 shows an overview of different climate factors (based on Jelle et al 2008, Jelle 2012a), which we use to evaluate the robustness of buildings and their components to climate conditions. The information in Table 2 is also the basis for the climate index we developed for the robustness framework, which is described later in this report.…”
