Box sash on ICF with Stone cill

[willbish]

Ive been playing around with a few design details for the windows.

 

What are your impressions of the following?

First pic, section through the middle of the window

Second pic, section at end, with 18mm ply three sided box,

 

 

Id like to keep the cill away from the concrete (warm) core if possible

The cill providers I've contacted seem happy for me to fix up through the cill into the window frame.

 

Undecided whether to have the cills as wide as the window or extend wider.

Wider is more traditional and commonplace, but I think shaping the EPS to accept the cill could be difficult

Shaping the eps will be simple, after playing with mine for a week you can chop it, cut it, screw it glue it, and if you cock it up just stick the cock up bit back in. 

Why don’t you come over and play with mine for an hour to get a feel for it. 

 

Now thats an an offer you don’t get every day.
