Hi,
I'm going to be cutting in a new window for a room I'm renovating. From what I can gather, my intended method is not the 'standard way' you would do this job, but still an acceptable way to do it. Let me explain;
The wall is cavity wall, block construction. I intend to cut the outer wall slightly smaller than the size of the window (UPVC frame) so that the window will butt up against the inner side of the outer blockwork. (The inner wall will obviously be cut large enough for the window to slot into.) My reason for this is that every other window in the house is installed thia way, meaning there is a 100mm recess on the outside for each window. If I were to fix the window to the outer block work as I believe it would normally be done, the recess would only be approx 50mm. Plus the cill would look different too.
Anyway, my question is what Lintels should I be using for this job. The existing Windows all have an Angle iron beam (L shape) both on the inner and outer walls. As far as whats above the new window, by the time its cut out, there'll be about one course of Block work, then its the roof (so trusses sitting on top).
Should I look to use Steel Angle Iron or is it better to use a concrete lintel? I notice the Steel Angle Iron doesn't seem that commonly available as Concrete or Catnic type lintels and wondered if there was a reason for this.
Thanks in advance.
