[Elecraft] Msg 4: Re heat in the Attic

[Edward]

Similar problem with a boarded attic too hot in summer, too cold in winter.   Fix:  (1) remove any lining to expose underside of the roof tiles   (2) Spray 125mm (4")  of polyurethane expanding foam over the tiles.  This (a) locks the tiles & prevents any roof movement (b) keeps out any dust (c) warm in winter  (d)  cool in summer  (e) reduces your heating costs.   It is a recognised building treatment & several companies will quote for the work.  Best done in summer as fumes can persist for a week or two.

Final thought:  if you can put in a velux double skin opening window in the roof with a 180 deg. opening –– preferably near a chimney stack.  You can then get at and mount antenna from a pair of steps through the window.  You need to install the window before you get the spray.
