Experiments for specific heat [J/(kg K)], or heat capacity, were conducted using a heat flow meter on unconditioned and dried samples at 10 °C, 20 °C, 30 °C and 40 °C.

Experiments for thermal conductivity [W/(m K)] were conducted using a heat flow meter on unconditioned and dried samples at 15 °C and either 45 °C or 65 °C.

Initial-mass-normalized mass loss rate [1/s] was measured in the simultaneous thermal analyzer experiments at three heating rates: 3 K/min, 10 K/min, and 30 K/min and mass loss rate [g/s] in the cone calorimeter at three heat fluxes: 25 kW/m², 50 kW/m², and 75 kW/m².

Cone Calorimeter Test Notes:
This material shrivels under thermal exposure which reduces the exposed surface area during cone calorimeter tests. An edge frame was used to limit this behavior. A calcium silicate substrate was included beneath the samples.

Experiments for heat release per unit area [kW/m²] were conducted on samples conditioned at 20°C and 50% relative humidity using a cone calorimeter at three different heat fluxes: 25 kW/m², 50 kW/m², and 75 kW/m².

Carbon monoxide yield was measured during cone calorimeter experiments conducted at heat fluxes of 25 kW/m², 50 kW/m², and 75 kW/m².

Experiments for specific heat release rate [W/g], were conducted using a micro-scale combustion calorimeter at a heating rate of 30 K/min.

Effective heat of combustion [MJ/kg] is calculated from data collected in micro-scale combustion calorimeter experiments.

The temperature at onset of decomposition [T_onset] is a derived quantity computed from data collected in simultaneous thermal analyzer experiments.

Band averaged emissivity was calculated from reflectance measurements conducted with an integrating sphere and Fourier transform infrared spectrometer.
