Attic Radiant Barrier Cold Climate

The problem quite honestly is that there is not that much radiant heat loss to begin with.

Attic radiant barrier cold climate.

In mixed and cold climates the living space can be the source of radiant heat compared to the attic. What about installing a radiant barrier in cold climates. Radiant barriers in mixed and cold climates. Mixed cold climates with no ducts or storage in the attic.

For an attic space our recommended installation method for radiant barriers is stapled to the underside of the roof rafters. The flat end walls in an a frame attic. This type of installation is easier than the conventional staple up method but it also has some precautions. The living space is typically kept around 70 o f while the attic temperature is lower possibly between 0 o f and 40 o f.

Roof deck air gap created manually with spacers radiant barrier foil insulation traditional insulation and lastly the sheet rock drywall layer. Typically your layers will go as follows from the roof down. But here something most people are not aware of that radiant barrier helps by making your. Another example would be someone who is in the midwest and they are planning to lay the foil over their attic floor but they use their attic for storage.

This being the case a radiant barrier is most effective when placed closest to the outside of the assembly in question. Reduced temperature of insulation results in less heat transfer into the conditioned space of the home source. Most recommendations for cold climates are to install the radiant barrier directly over the insulation. For really low pitched attics with items in the attic space.

Throughout the balance of this digest the terms attic and roof will and can be used interchangeably. For example if you live in a cold climate but you have an hvac unit in your attic a hybrid method of laying the foil down and stapling it up is probably your best method. In cold climates the preferred installation method is laying radiant barrier foil over the insulation on the attic floor to keep heat in during the cold months and to help block heat in hotter months. We currently live in wyoming where winter temps often get below 0 degrees.

If you choose to install over the attic floor keep in mind that condensation may form under a perforated radiant barrier based on sudden extreme temperature differences between the air below the barrier and above the barrier typically found in colder climates in the. However using the same theory applied to warm climates and reversing it. It makes sense that this would maximize the the potential to keep heat in during the winter and then keep out some of the heat in the living areas during the summer. In cold climates the primary purpose of attic or roof ventilation is to maintain a cold roof temperature to control ice dams created by melting snow and to vent moisture that moves from the conditioned space to the attic ventilation acts to bypass the vapour barrier created by most roof.
