Thermal Blankets


Thermal Blankets


Research at Pennsylvania State, Rutgers and other universities has shown that the addition of thermal blankets to the greenhouse interior decreases heat losses because of radiation, convection and infiltration. Thermal blankets reduce air stratification and the amount of space to be heated. For this reason, they are more effective in large span houses and pulled from gutter to gutter rather than gutter to ridge. To be effective, blankets must be sealed tightly at the edges, as any openings allow formation of drafts that draw warm air just as a damper left open in a fireplace does. Annual fuel savings may range between 20-40% with an initial total installed cost of $.50-$2.00 per square foot.
