This application is related to U.S. Patent Application Nlllllber~ 10/076,211 by Trpkovslci filed Febniary 12, 2002.
The entire disclosure of tile above mentioned patent applications is hereby incorporated by reference.
Field of the Invention Tlle present invention relates generally to protective masking material that can be applied to insulating glass units, monolithic panes, and other workpieces.
More particularly, the present invention relates t0 advalltageoLiS C011~1gllrat1011S Of lnasklng material which may be easily removed from a worlcpiece.
)3aCICgTOlllld Of the IllVellt1011 I11 11105t 111diiStrlahzed C01111tr1e5, W111d0WS t011Ch people's lives everyday. Wherever people work and live there are windows. Windows allow the occupants of a building to view the outside world while allowing sun light to enter the interior of the building. Sunlight is a natural antidepressant and helps the human body produce vitamin D. Thus, a certain amount of sunshine is essential to mental and physical well being.
In extreme climates significant energy play be lost through windows during the winter when a building is being heated, and/or during the slunmer when a building is being cooled.
With the rising cost of energy, efforts have been made to provide homes and other buildings N'lth 111SLIlat1011 that will nl0re eff Clelltly pl'evellt tile transfer of heat between the inside and the outside oi~ a building. Insulating glass units have been developed to reduce the a111ount of heat transfer thrOllgll W111dOWS.
There are basically three types of insulating glass units commercially available today.
These three types are often refeled to as single glazing, double glazing, and triple glazing.
Double glazed insulating glass units are the 2110st common. These msulatlng glass units include a space sealed between two paales of glass. This sealed space provides insulation, the IllSll~~ltlilg e('leCt may be enhanced by filling the space with an insulatlVe gas 5llch aS argon, Or lcryptol-I. Compared with a single pane, a double glazed insulating glass unit can cut heat loss tluough a window nearly in half.
Because of the dramatic energy savings which can be achieved with insulating glass units, building codes in many jurisdictions have been revised to require the installation of insulating glass units. The relative energy performance of these insulating glass units is clearly an impol"tant factor to be considered when windows are purchased by a consumer.
The federal govenunent of the United States of America has developed an Energy Star designation which may be used to identify windows which meet certain energy performance criteria. In another attempt to help consumers make inforned decisions regarding window purchases, the National Fenestration Rating Council (NFRC) has,recently instituted new labeling requirements for windows. The NFRC requirements include both a permanent marking and a temporary label. The NFRC label includes ratings for U-factor, Solar Heat Gain C.oeflicient (SHGC), Visible Transmittance (VT), and air leakage (AL).
These ratings must be provided for both residential and non-residential applications. All of these ratings typically vary from one window to the next. The labeling of windows may also include additional infornation such as a model number, the window style, the window dimensions, and a date code. This information also typically varies from one window to the next. The labeling requirements described above present a challenge to window manufacturers since a great deal of information is required, and since this information frequently varies from one window to the next.
Human beings have a relatively narrow temperature range in which they are comfortable. Unfortunately, infrared (IR) energy from the sun entering a room through a window can quickly raise the temper ature to an uncomfortable level. Many windows include low emissivity coatings that have been developed to prevent heat spilces within a room by reflecting a large portion of incident infra red energy. Recently, self cleaning coatings have also been developed for use on window glass. These coatings may eliminate the need to clean the glass of an insulating glass unit.
Because the glass of an insulating glass unit typically includes special coatings, temporary labels that are applied to the glass are typically manufactured using special paper and special inlcs so that the coatings on the glass will not be damaged. The coatings on an insulating glass unit may also be damaged during transportation to a building site, or during the building process. The building process typically involves the efforts of a variety of crafts people. such as carp-enters, masons, and painters. During the building process the coatings on an insulating glass unit can be scratched or covered with paint.
Summary of the Invention The present invention relates generally to protective masking material that can be applied t0 111S111atlllg glaSS L1111tS, monolithic panes, and other worlcpieces. More pal-ticularly, the present invention relates to advantageous conflgllrations of masking material which may be easily removed from a workpiece. An assembly in accordance with an exemplary embodiment of the present invention comprises a pane having a face and a protective covering overlaying the face of the pane.
In some implantations, the protective covel-ing includes a free portion which overlays the face of the pane and is easily lifted away from the face of the pane. In some advantageous implementations of the present 111Ve11t1011, the free portion of the protective covering is dimensioned so as to be easily pinched between the thumb and index finger of a human hand.
Some implementations of the present invention include a pull tab comprising a pol-tion of a strip which extends beyond an outer perimeter of the protective covering. In some cases, the pull tab extends between the outer perimeter of the protective covering and an inner border of a frame.

Field of the Invention Tlle present invention relates generally to protective masking material that can be applied to insulating glass units, monolithic panes, and other workpieces.
More particularly, the present invention relates t0 advalltageoLiS C011~1gllrat1011S Of lnasklng material which may be easily removed from a worlcpiece.
)3aCICgTOlllld Of the IllVellt1011 I11 11105t 111diiStrlahzed C01111tr1e5, W111d0WS t011Ch people's lives everyday. Wherever people work and live there are windows. Windows allow the occupants of a building to view the outside world while allowing sun light to enter the interior of the building. Sunlight is a natural antidepressant and helps the human body produce vitamin D. Thus, a certain amount of sunshine is essential to mental and physical well being.
In extreme climates significant energy play be lost through windows during the winter when a building is being heated, and/or during the slunmer when a building is being cooled.
With the rising cost of energy, efforts have been made to provide homes and other buildings N'lth 111SLIlat1011 that will nl0re eff Clelltly pl'evellt tile transfer of heat between the inside and the outside oi~ a building. Insulating glass units have been developed to reduce the a111ount of heat transfer thrOllgll W111dOWS.
There are basically three types of insulating glass units commercially available today.
These three types are often refeled to as single glazing, double glazing, and triple glazing.
Double glazed insulating glass units are the 2110st common. These msulatlng glass units include a space sealed between two paales of glass. This sealed space provides insulation, the IllSll~~ltlilg e('leCt may be enhanced by filling the space with an insulatlVe gas 5llch aS argon, Or lcryptol-I. Compared with a single pane, a double glazed insulating glass unit can cut heat loss tluough a window nearly in half.
Because of the dramatic energy savings which can be achieved with insulating glass units, building codes in many jurisdictions have been revised to require the installation of insulating glass units. The relative energy performance of these insulating glass units is clearly an impol"tant factor to be considered when windows are purchased by a consumer.
The federal govenunent of the United States of America has developed an Energy Star designation which may be used to identify windows which meet certain energy performance criteria. In another attempt to help consumers make inforned decisions regarding window purchases, the National Fenestration Rating Council (NFRC) has,recently instituted new labeling requirements for windows. The NFRC requirements include both a permanent marking and a temporary label. The NFRC label includes ratings for U-factor, Solar Heat Gain C.oeflicient (SHGC), Visible Transmittance (VT), and air leakage (AL).
These ratings must be provided for both residential and non-residential applications. All of these ratings typically vary from one window to the next. The labeling of windows may also include additional infornation such as a model number, the window style, the window dimensions, and a date code. This information also typically varies from one window to the next. The labeling requirements described above present a challenge to window manufacturers since a great deal of information is required, and since this information frequently varies from one window to the next.
Human beings have a relatively narrow temperature range in which they are comfortable. Unfortunately, infrared (IR) energy from the sun entering a room through a window can quickly raise the temper ature to an uncomfortable level. Many windows include low emissivity coatings that have been developed to prevent heat spilces within a room by reflecting a large portion of incident infra red energy. Recently, self cleaning coatings have also been developed for use on window glass. These coatings may eliminate the need to clean the glass of an insulating glass unit.
Because the glass of an insulating glass unit typically includes special coatings, temporary labels that are applied to the glass are typically manufactured using special paper and special inlcs so that the coatings on the glass will not be damaged. The coatings on an insulating glass unit may also be damaged during transportation to a building site, or during the building process. The building process typically involves the efforts of a variety of crafts people. such as carp-enters, masons, and painters. During the building process the coatings on an insulating glass unit can be scratched or covered with paint.
Summary of the Invention The present invention relates generally to protective masking material that can be applied t0 111S111atlllg glaSS L1111tS, monolithic panes, and other worlcpieces.
