    Hello all,

    planning to remove brickwork and install a 530 x 910 window in my place. Have annexed part of our bedroom for an ensuite in our new place. The with of the widow ( think those were the measurements ) equate to an opening 4 bricks poss 5 wide by however many below. Will install a concrete lintel on either skin but what I want to know is should anything else go in the cavity above the head on the casement?

    Place is 50 years old with brick exterior and blocks on the inner skin and the windows are sat on the external brickwork with cills

    Why would you install a concrete lintel in the outer skin if it's brick?

    I'm willing to be guided though Freddy....... :)

    CG50/100 catnic lintel and incorporate a cavity tray with perp vents, the sides can be closed off with cavity closers (if you can get them to fit), if not then stuff with rock wool or a fire sock, as your creating an opening then you'll probably find BC will need to be informed

    And this can be retrofitted? Looks like it would be a new build product

    You can remove 2 or 3 courses outside and slide this back into situ, you now have access and can then create your cavity tray before relaying a handful of bricks along with perp vents. You could of course fit a single skin catnic or some 80mm x 100mm angle iron to the outside and still fit a concrete lintel inside

    Is there anything wrong with fitting a single concrete lintel on the inner and then outter skin though? Just assumed it would be quicker to do. Is this just an asthetics thing?
