It saves your time lapse photos in-app (rather than to your camera roll) for you to export to the location of your choice: your photo library (as individual photos), the Glimpse Cloud, or SyncDocs. The latter two store your photos as movies/glimpses; they are free but do require you to have an account.
Insulation works by reducing the transfer of heat by means of a barrier. Unfortunately in most cases the better the insulation the more it costs, so like most things a balancing act is required. To understand insulation you need to know what thermal conductivity, R values and U values are. Thermal conductivity is the measure of how easily heat flows through a specific type of material, regardless of the thickness of the material. The lower the thermal conductivity of a material, the better the thermal performance (i.e. the slower heat will move across a material). See below for some example materials and there conductivity values.
In physics, thermal conductivity (often denoted k, Î», or Îº) is the property of a material to conduct heat. It is evaluated primarily in terms of Fourier's Law for heat conduction.n SI units, thermal conductivity is measured in watts per meter kelvin (W /(m Â· K)). The dimension of thermal conductivity is M 1 L 1 T â3 Î¸ â1. These variables are (M)mass, (L)length, (T)time, and (Î¸)temperature. In Imperial units, thermal conductivity is measured in BTU /(hr Â· ft â Â°F).
