Should I Really Care About My Home and Garden

Should I Really Care About My Home and Garden

Providing some good home and garden furniture for it

If you ask anyone that enjoys his life about the
two things he cares about the most, you would probably find a unique
answer: car and home; the car because it is what you use to move from a
place to another so you want it to be nice looking and comfortable; and
the house because it is where you spend the most of your time so you
want it to be relaxing.

Why is an SHGC important?

The SHGC is the fraction of incident solar radiation admitted through a window, both directly transmitted and absorbed and subsequently released inward. SHGC is expressed as a number between 0 and 1. The lower a window's solar heat gain coefficient, the less solar heat it transmits. The nationally recognized rating method by the National Fenestration Rating Council (NFRC) is for the whole window, including the effects of the frame. Alternately, the center-of-glass SHGC is sometimes referenced, which describes the effect of the glazing alone. Whole window SHGC is lower than glass-only SHGC, and is generally below 0.8.

Why is an SHGC important?

Solar heat gain can provide free heat in the winter but can also lead to overheating in the summer. How to best balance solar heat gain with an appropriate SHGC depends upon the climate, orientation, shading conditions and other factors. ENERGY STARprovides simplified guidance on recommended SHGC values for your climate; additionally, the Window Selection Tool compares average simulated energy costs for your location based on various window types.

What about R-Value?

Roughly speaking in the context of building and construction, the R-value is a measure of how well a two-dimensional barrier, such as a layer of insulation, a window or a complete wall or ceiling, resists the conductive flow of heat.
