Roof Substrate Canary Considerations

Traditionally roof substrates are made of CDX plywood. However the glues used in manufacturing the CDX plywood gas off slowly and impact many canaries, despite being covered with underlayment above and insulation below. A safer product is corrugated metal decking material, 20g typically. This is available in custom cut lengths similar to standing seam metal panel roofing. Other alternatives to …

The Mechanicals

Much thought went into where to place the mechanicals and electrical so as to minimize their impact on the life of a canary. For this build, we decided on a completely separate utility building. This building will house the electrical panel, the telecommunications panel and devices, the radiant floor heat distribution panels and manifolds, hot water heater device and water filtration requirements. The building is approximately 10×12 and sits 8’ away from the house itself. Placing the mechanicals in a separate building maximizes the reduction of impact to canaries. But the services still must make it into the house even if the devices are situated outside of the house.
