[MassHistPres] Brick nogging

[Anne Forbes]

One aspect of the insulation function of brick nogging, if it fills the wall cavity reasonably tightly, would be for a wind stop.  Which was of course also what the later back-plastering performed very well.  Not to mention all those wadded up bits of newspaper we sometimes find stuffed between sheathing boards.

  In later 19th century houses one sometimes finds "back plastering" where there is a layer of lath and plaster inside exterior walls (especially north side).  This practice appears to be designed to create a double air space for insulation purposes.  I'm guessing that it started after cut nails and sawn lath decreased the price of plastering and that it was a logical improvement over brick nogging.

  James Garvin's Building History of Northern New England has a good photograph and brief discussion of brick nogging on p. 53.  When a north wall of my house (c 1725) was opened for a sill repair we discovered nogging of bricks (whole and broken) and clay.  In addition to the reasons already raised (insulation, fire retarding) I have wondered if the practice might have been simply a vestige of English building practice.  It seems more deliberate than simply a means to dispose of construction refuse.
