	The second issue with including windows, doors, and other forms of fenestration is that simply including these products decreases the efficiency of the insulation in a home. By putting in a window of a door and removing part of the insulation in the wall of a home, the effective [[R-value]] of that wall is reduced. This leads to a reduced ability to resist the flow of heat within a home. To avoid this it is vital to ensure that quality insulation is used and installed properly.

	Guidelines for how a home must include windows and doors varies across Canada. For colder regions, the necessary factors for a window or door to be considered ''energy efficient'' are more strict. In ~~colder~~, ~~more~~ northern regions windows can only have a maximum [[U-value]] of <m>1.20 W/m^2K</m> whereas warmer regions can have a u-value of up to <m>1.80 W/m^2K</m> and still be considered energy efficient.<ref>National Resources Canada.

Available: http://www.nrcan.gc.ca/sites/www.nrcan.gc.ca/files/energy/pdf/energystar/Fenestration-Spec-E-Residential-October-2010.pdf</ref> Generally speaking a ''lower'' U-value indicates a higher level of insulating power.

	The inclusion of openings in the building envelope is necessary for people to live comfortably inside a building (or even get in and out of them in the first place). Openings such as windows allow natural light into the home and can promote [[passive solar heating and cooling]], as well as providing natural points of ventilation ~~and~~ air circulation and fire exits. Doors are also vital to a buildings design to provide a point of entry and exit to the building. Skylights provide similar benefits as windows, however they generally do not open. ~~Including~~ energy~~-efficient openings into a home~~:<ref name="NRCAN2">National Resources Canada.

* '''Increase comfort''' by reducing drafts and making a house feel warmer during the cold season.
* '''Improve indoor air quality''' by reducing condensation, preventing mold growth. As well, a tighter seal into the home prevents external contaminants from entering the home.
* '''Saving money''' by minimizing air leakage, improving the performance of [[furnace]]s and [[HVAC|air conditioners]], and improving the thermal performance of windows.
* '''Control condensation''' due to the fact that energy-efficient windows stay warmer on interior surfaces, allowing for a higher level of relative humidity without condensation. This in turn allows windows to last longer, decreasing the need to replace them as frequently.

==Issues due to Fenestration==
All fenestration products experience a degree of [[heat]] loss due to:<ref> National Resources Canada. (March 28, 2015). ''Fenestration Technology'' (Online). Available: http://www.nrcan.gc.ca/energy/products/categories/fenestration/14432</ref>

* [[Radiation]]: heat energy is absorbed by the material of the door or window and radiates toward the cooler side.
* [[Conduction]]: heat energy moves through the solid materials that make up the frame or other parts of the window, door, or skylight.
* [[Convection]]: heat energy is transferred to the air between parts of the window or door.
* [[air infiltration|Air leakage]]: heat energy is transferred to air moving through seals or gaps in the door or window
