Eagle Shield Insulation
Cold climates
In cold conditions, the main aim is to reduce heat flow out of the building. The components of the building envelope - windows, doors, roofs, walls, and air infiltration barriers are all important sources of heat loss; in an otherwise well insulated home, windows will then become an important source of heat transfer. The resistance to conducted heat loss for standard glazing corresponds to an R-value of about 0.17W/m2/Ko (compared to 2-4W/m2/Ko for glasswool batts). Losses can be reduced by good weatherisation, bulk insulation, and minimising the amount of non-insulative (particularly non-solar facing) glazing. Indoor thermal radiation can also be a disadvantage with spectrally selective (low-e, low-emissivity) glazing. Some insulated glazing systems can double to triple R values.
Eagle Shield Radiant Barrier - Floors
Radiant barriers are also quite effective in floor systems above unheated basements and crawl spaces. The radiant barrier may be either stapled below the floor joists, creating a single reflective air space, or between the joists, followed by some type of sheathing. Radiant barrier works extremely well in this application for two reasons.[9] First, a radiant barrier that is not perforated for breathability acts as an excellent vapor barrier. This means that ground moisture will not be able to pass through the radiant barrier and enter the living space. Secondly, the floor is the only part of the building where the heat flow is always down, unlike a roof where the heat would be coming down during the summer and rising to escape in the winter.[13] When the heat flow is down, 93% of the heat is radiant heat, which is exactly what the radiant barrier is designed to block.(Garrett Harwood article)
Eagle Shield Franchise Group terms and definitions:
Adhesive
A substance used to bond materials by surface attachment.
Cellular Polyurethane
Insulation composed principally of the catalyzed reaction product of polyisocyanate and polyol compounds, processed usually with fluorocarbon or hydrocarbon gas to form a rigid foam having a predominately closed-cell structure.
Eagle Shield Industries
Knee Walls
Walls of varying length. Used to provide additional support to roof rafters with a wide span or to finish off an attic. An example of these are the short walls usually found in the top floor/attic of a cape cod style home. Garrett Harwood
Heel
The outside radius of an elbow.
