One of the biggest causes of heat-gain/loss in a home are the gaps and cracks around windows and doors. The U.S. Department of Energy reports that windows alone are responsible for up to 25% of a home’s heating bill.
In the days before central heat-and-air, energy efficient windows-and-doors, and high R-value insulation, homeowners had to think of other ways to control room temperatures than simply adjusting the thermostat. For many homesteaders living in old farm houses or making do with relatively old school accommodations (i.e. without expensive HVAC systems), adopting these old methods is a no-brainer.
One such low-tech, economic, and surprisingly effective solution for slowing the rate of heat-gain/loss in a house is with thermal curtains or drapes which can increase a window or door’s insulative value up to 7 times its existing rating. To improve the effectiveness of this method, Wrap Curtain Rods help draw the thermal material flush against the wall, minimizing gaps for air to leak through.
