Grappling with a little project and having a headache with a window.....
I am putting a little window (building regs fire escape size 600mm wide x 750mm tall) in the gable end of a single storey loft conversion - the room is tiny, 1.7m wide with vertical walls just 1.2m running into skeelings that apex at just 2m high. Consequently the available space to fit the window is pretty tight and I am working in a fairly small triangle....
The problem I have is that the gable wall is a cavity and the exterior is rendered - I need to try and fit all the lintels etc from inside to avoid damaging the render and exterior finish..... so I eventually end up cutting out an exact window sized hole in the exterior finish / outer leaf, into which I slot the window, with everything on the inside / inner leaf already completed.
I will be fitting a lintel to the inner leaf anyway and could use some recommendations for the thinnest / easiest lintel to use here. I basically have to get the lintel as high up the triangle formed in the gable (i.e. as far from the floor) as possible so the bottom of the window is well above the 800mm level from the floor. I was thinking of using something like an IG L10. With the recommended 150mm bearing either end of the lintel, plus the 600mm width of the window, you can see how I have very little room for manoeuvre.....
That got me to thinking how I was going to get a lintel fitted in the outer leaf.... and then I thought maybe I actually wouldn't need one....
The outer leaf of the gable isn't supporting the roof structure and there is only about 1m of blockwork above the 600mm window opening, so I am wondering if the (wooden) window itself would be sufficient to act as a lintel in this case..... What do you think?
