The Green Place markets both radiant barrier and reflective insulation. We are a Canadian distributor for a major American supplier. The products we carry are heavily tested against many specifications to ensure their quality. They are all built around a metalized film approach. They are non-toxic, non-carcinogenic, easy to handle, and require no maintenance. Unlike many other products, they meet ASTM E84 and E2599 fire codes which gives them a Class 1 / Class A fire rating.
We stock three grades of radiant barrier, which vary slightly in properties and applications. All are available in 500 and 1000 foot rolls that are 4 feet in width. They are designed to meet ASTM C1313 specifications for sheet radiant barriers for building construction applications. Additionally, they have been tested to comply with other ASTM specifications:
flame spread: 0|
smoke development:as low as 5
overall rating: class a / class 1
|Resists||fungi3, corrosion4, cracking5, bleeding5, and delamination5|
Our best product is designed for industry. It can be used as building wrap, on top of the rafters, or inside the rafters. Finally, it can be used underneath radiant heat flooring. It is reinforced with a polyethylene weave that is similar in texture and appearance to tarpaulin material. Specifications:
|Weight||33.2 pounds per 1000 foot roll|
along length: 24.59 pounds|
along width: 21.49 pounds
For residential applications that require some strength, this grade may be preferred. It is reinforced with cross-laminated polyolefin.
|Weight||16.35 pounds per 1000 foot roll|
along length: 4.53 pounds|
along width: 4.48 pounds
Our least-expensive grade, this product is no less reflective than the above grades, but is somewhat more delicate. It is especially useful for residential retrofit and attic insulation. It is reinforced with polyester scrim. This is the only product that scored more than 5 in smoke development2.
|Weight||16.35 pounds per 1000 foot roll|
along length: 2.32 pounds|
along width: 1.50 pounds
Our reflective insulation comprises one or two layers of bubble film laminated between one or two layers of metalized film. In the case where only one layer of metalized film is used, white polyethylene is substituted. It provides similar properties to the radiant barrier products, with the additional advantage of providing conductive insulation. It will re-radiate only 5% of heat in which it comes in close physical contact with, compared to the approximate 90% re-radiation of ordinary building materials at the same temperature. It is an excellent reflector of all long-wave radiant heat that strikes it, reflecting up to 95%. Depending on installation technique, it can provide insulation values anywhere from R1.1 (compact subfloor installation) to R16.8 (between floor joists with air space).

Our reflective insulation is available in rolls 4, 5, and 6 feet wide, comprising 300 and 500 square feet of coverage. We can also provide 8 and 10 foot widths by special order. The thickness varies depending on the number of bubble layers. Each layer adds 1/8".

All thermal values are corrected for frame loss. "Exposed to interior" values include the thermal resistance of the interior air film: 1.32 up and 4.55 down. In the post-frame case, K-values are equal to U-values.
Post-frame walls were tested with an assembly consisting of corrugated metal exterior, 2" x 4" girts, insulation, a 4" x 6" to represent the support beam, and 1/2" wafer board as an interior wall covering.
|exposed to interior||4.50||0.222|
|exposed to interior||4.91||0.204|
All thermal values are corrected for frame loss. "Exposed to interior" values include thermal resistance of 1.70 for interior air film.
