Samples of silica aerogel were acquired from LBL.gov lab. ![]() This pilot study, presented in this paper, is an attempt to test the feasibility of using aerogel for this application. The use of silica aerogel in fireplace glass doors was not reported in the literature. In recent years, some commercial application of silica aerogel in fenestration insulation is being examined. Characterization of silica aerogel and its material properties were thoroughly studied over the past couple decades. The use of silica aerogel as an insulation material has been demonstrated in numerous studies and are sample of these studies. Aerogel is classified as a mesoporous porous material since its pore size ranges between 2 to 50 nanometers. The following properties listed in Table 1, indicates how rigid silica aerogel hold records properties compared to most know thermal insulation materials.Īn aerogel is an open-cell solid foam that is porous and composed of a network of nano-sized pores. Rigid silica aerogel SiO2 in its primitive formulation is one of the lowest conducting solids known in industry. The current work being presented in this paper demonstrates a pilot experimental investigation of using rigid silica aerogel as a transparent thermal insulation to fireplace glass doors. The manufacturers responded to these new requirements by adding permanent barriers and standalone barriers to enhance safety. In 2012, American National Standard Association (ANSI) along with Canadian Standard Association (CSA) approved a new safety standard requiring maximum fireplace glass temperature not to exceed 172 F (77.78 oC). ![]() The industry mainly uses tempered soda-lime commercial glass on medium range hearth appliances and high-end ceramic glass on premium products. The hearth industry produces gas-fired hearth appliances that utilizes glass doors to allow radiative heat transfer while keeping combustion products completely sealed from the chance to leak into the heated room. Hearth industry in the USA is facing lots of litigation due to child first and second-degree burns from broiling glass fireplace doors. Higher degree burns from hot fireplace glass has been a recently increasing safety hazard, more frequently with children touching the hot glass of fireplaces and stoves. Keywordsaerogel insulation hearth appliances child safety heat transfer gas-fired fireplaces and stoves (key words) The preliminary outcome presents some challenges related to high aerogel hygroscopy while presenting a potential for enhancing the safety of hearth appliances when it comes to be touched by children during operation. This paper presents the results of this pilot study in the form of temperature measurements across the exterior surface of hearth appliance that is gas-fired. The process to investigate this study is purely experimental. The aerogel provides a high temperature effective insulation material to lower the temperature of outside surfaces of hearth appliances (fireplaces and stoves).
