Custom details?

This week's item is a quick forum post rather than a news story, and it doesn't carry much for someone planning upgrades on their own house. A homeowner working with a designer asked a building-advice site whether it could produce custom drawings for two parts of a new home: an unvented roof (a roof assembly built without the usual attic venting, insulated instead at the roofline) and a window installation detail, for a house built with AAC block, a lightweight insulating concrete material sometimes used in place of standard framing.

There's no answer or guidance included, no product recommendation, no rebate or program news, and no broader finding about how unvented roofs or AAC construction perform. It's simply a homeowner or their designer asking a community of building professionals for help with construction drawings for a specific new-build project.

If you're renovating or building and considering an unvented roof assembly, the general idea is that insulation sits against the roof deck rather than at the attic floor, which changes how the roof needs to be sealed and vented, or not vented, at the edges. Window details matter for the same reason: how the window meets the wall affects water and air control. Anyone using AAC block or planning an unvented roof on their own home would want site-specific drawings from a designer or engineer familiar with that combination, since the assembly is less common than standard wood-frame construction.
