How do you INSULATE above a Trane Concealed Heater?

Wisconsin sure is COLD🥶 Have Trane’s “unobtrusive & revolutionary” Heat Convectors in my 1933 home and they work great! The large front window in the living room has a handsome 18” deep wooden window sill with a Trane heat cabinet hidden beneath. Other rooms have Trane’s Concealed Heaters in the wall.

For over 20 years, there has been a perennial ice dam problem along the front north-facing roof line. The ice thaws by March and lands on the driveway. It can be a solid ice slab 6’ X 3’ X 1’ !

In January I am finally having some weatherizing work done focused on the north-facing roof line to prevent the ice damming. Uninsulated knee wall closets will get closed cell spray foam insulation to create a thermal barrier (hot/cold) air barrier.

The north facing bedroom above the attached garage has a Trane’s Concealed Heater unit directly beneath a window.
The contractor asked if the Trane unit could have insulation put above the vent grill. The heat is escaping out to the edge of the roof.

Issue : The bid states “We will attempt to gain access to the area below the dormer with the boiler register. If possible, we will insulate the sloped area; this will be determined on-site by the production crew.”

Question: Can they put insulation above the vent grill?

Hope you will share your knowledge and wisdom! Thanks so much!

    I tried to picture what you're describing and couldn't. Could you include a photo or drawing of where you're trying to prevent the heat from going?

    You just want to insulate outside the cabinet, right? It should be able to use pretty much anything, the outside of the box at worst will get to steam temp of about 210 f.
