Conference and Exhibition | May 29-31

Groke Door is going to be at the Dwell on Design Show in LA. Come and check out our modern entry doors at our booth #2235.  
A three-day exhibition and conference, comprised of one trade day and two consumer days, at the Los Angeles Convention Center featuring world-class speakers, product demonstrations, continuing education classes for design professionals, and seminars for design-seeking consumers. Each year, Dwell editors carefully craft a program that invites you to “step into the pages of Dwell” and experience modern design.

You hear the terms U-Factor and R-Value a lot but do you really know what it means? Both are measures of energy performance but are reached in very different ways.  Most of us know that the higher the R-Value the better the insulation and therefore the better the energy savings for our homes.  We also understand that if the R-Value is high then the U-Value or U-Factor is low.  In order to understand how these ratings can help us make wish decisions about investing in energy savings we must clearly understand what the ratings mean.

R-Value is a measure of resistance to heat flow.  Generally, R-Value is given for a certain thickness of specific material, such as fiberglass wall insulation.  The R-Value of a structure can be estimated by simply adding up the R-Value of each material that makes up the layers in the wall (exterior sheathing, insulation, interior drywall, etc.).
