Modular energy saving covering

An energy saving modular covering comprising:

• a plurality of covering modules each formed of flexible material and having an insulating central body portion surrounded by an outwardly extending first flange;
• a second flange formed on each of said covering modules extending from said central body portions beyond said first flange;
• and
• fastener means attached to at least one of said first flange and said second flange on each of said covering modules whereby said fastener means of adjacent ones of said covering modules cooperate to releasably couple said modules together to form the modular covering and said second flanges of each of said covering modules overlie said first flanges of each of said adjacent ones of said covering modules to form infiltration barriers militating against the transmission of heat energy and water vapor from one side of the modular covering to the other side.

An energy saving covering module, adapted to be detachably connected to a plurality of like modules, comprising:

• a central body portion having a pair of spaced apart walls attached together about peripheral edges defining an interior space therebetween;
• an insulating material positioned in said interior space;
• a first flange extending from said peripheral edges of said central body portion;
• a second flange extending from one of said peripheral edges of said central body portion and outer peripheral edges of said first flange;
• and
• fastener means attached to at least one of said first flange and said second flange whereby said fastener means are adapted to cooperate with fastener means attached to adjacent ones of said covering modules to form a modular covering sheet with said second flanges overlying said first flanges of adjacent ones of said covering modules forming an infiltration barrier to the transmission of heat energy and water vapor from one side of the modular covering to the other side of the modular covering.
