Drawing upon commerce content of Phillip Norman Attic Access, and more. For provocative advocacy of policy on residential weatherization, please find parallel discussion at blog energyconservationhowto. At the blog, choose Label: Attic Access.

This is imagined as a commerce enterprise serving all worthy products and installation services, of insulated and gasketed service doors in residential construction. The insulation in such doors will be constrained by practicality to as little as R5 in US measure, looking at just the foam insulation panel in a door, with wood elements that cause poorer overall R-value. This is the typical standard for an excellent exterior door, Energy Star rated. The standard is U-factor less than 0.30, R greater than 3.3, for the average heat conducted through door faces. An R5 extruded polystyrene insulation panel is one inch thick. Worthy insulated doors with U less than 0.3 will be about 1 1/4" minimum thickness. Practical doors will rarely be more than two inches thickness. Service doors include drop-down attic ladders, a door to a closet outside home heated spaces, attic and crawl space removable hatches, and more. 

Products which will be honored at this web site include attic ladders by Fakro, Calvert, SSC MidMade ,and Rainbow. Visitors will include smarter builders and do-it-yourself homeowners. Visitors will be referred from all sales outlets including big-box and neighborhood hardware stores. The goal will be public service, with fair compensation to contributors, from benefiting manufacturers. Everything will work out, over time. No one will profit from a hoarding of content.
