TRUEGREEN HEMP INSULINER
The absolute best in Winter heating and Summer cooling savings
-Hemp/ Cotton blend. Sustainably produced in Northern China without the use of chemicals/ herbicide/ pesticides/ or universally standard milling & processing treatments. (Companion planted, lightened with hydrogen peroxide and softened with mineral/water based softener).
-Hand crafted in partnership by real people in a socially responsible manner including minimum working age of 18, with access to infirmary, daycare, housing, fair wages, Karaoke, and break/nap time!
-Earthshade Hemp Insuliner™ has an average calculated “R” value of 4.5 depending on face fabric and mounting attributes. When compared to Petroleum based (polyester) single honeycomb shade of R3.65, Double honeycomb: R4.3, and triple honeycomb: R 4.8, Earthshade Hemp Insuliner™ shades are the only environmentally secure, energy saving option with real aesthetic charm. (Tests performed in-house on double glazed economy window with an average base R value of 1.5)
HEAT LOSS EXPLAINED: A window system attempts to minimize 3 forces that together equal higher heating and or cooling costs.
-Conduction, or transfer of energy through materials. A materials “R” value attempts to describe a measurement of this transfer. The higher the “R” value, the slower the rate of transfer. Most double glazed gas filled window systems boast a whopping R 1-3! while an average insulated 2 x 4 constructed wall will measure an average R 13 (2 x 6: R 19)!
-Convection, or the transfer of energy due to density of the air; I.e. heat rises and cool air sinks. This is of particular concern when considering the most efficient fit of a window shade. Once a shade is mounted, an air space is created between the shade and the glass. The heat will transfer faster through the glass because of the “heat sink effect” leaving the air cooler or more dense. Higher density or cooler air is heavier than lower density or warmer air and therefore has a tendency to drop towards the window sill instead of crawling around the sides of the shade making tracks, velcro, or side rails an unnecessary additional cost to the owner and the environment.
-Pressure refers to the efficiency of the window systems ability to resist the wind. This is where the proper fit as well as the following points will have a remarkable effect on the TOTAL SAVINGS OF THE TOTAL WINDOW SYSTEM;
-Window type: single, double, or triple glazing, and type of space between (Argon) or coating applied to glass (low “E”).
-Efficiency of manufactured seals and or weather stripping (the “breeze” effect).
-Amount of insulation in the wall cavity around the installed window including proper sealing or caulking.
-Type and installation style of interior window trim (may dictate shade mounting parameters to a degree).
TRACKS OR NO TRACKS? -Some manufacturer's supply side tracks in forms ranging from simple velcro to actual PVC or aluminum side track systems to “seal” the side of the window shade to the window. EXTENSIVE TESTING HAS SHOWN THIS PRACTICE IS OF LITTLE GAIN ultimately resulting in the overuse of raw material and premium pricing.
