Are 16" o.c. eave chutes (a.k.a. baffles, Proper Vents) still made?

I'll be installing chutes, followed by 2-part foam at the perimeter. I'd rather get full-width chutes between the rafters rather than breaking the perforated 24" o.c. ones in half.

We bought a 1938 single story home. I plan on documenting the energy retrofits. (Maybe even create a blog?) We've already had a "Home Performance with ENERGY STAR" inspection done. First project is to remedy the ice damming. Would using layers of Thermax at the edge, then foaming that into place get a higher R-value above the top plate than only foam?

What are those thingies called, anyway? Here's a list of possible names: Propervent, ventilation chutes, ventilation channels, ventilation baffles, attic vent baffles, insulation baffles, rafter ventilation channels, vent baffles... You get the idea. I like to call them "ventilation baffles."

Many manufacturers make them. Here's a partial list:

ADO Products

Brentwood Industries




Insulation Solutions

Owens Corning

Perma R Products

Polar Industries
