    1st floor - floor joist crack

    So out of mental complexity. I am blocking the joist against the twist, then sister the other side. As I am here, I will then block all the joists and plywood all notches that need it.

    1st floor - floor joist crack

    Something like this maybe (below)? notch top, metal plate and bolt down? as found in a different thread. Either bridging the notched area or just over the cracked area, or span the notch and a length over the the length of substantial cracking?

    1st floor - floor joist crack

    It is what I expected! Is it worth herringbone or blocking at the significant cracking point, against the twist. Then sistering the other side?

    1st floor - floor joist crack

    Hi All! Doing some renovation and my brain just noticed this a joist crack, see images. Joist dimensions are 165 mm x 74 mm. As far as I can tell, the crack runs the length of the joist within the room (3.45 m), on botch sides of the notch. Becoming more hairline after about a metre from the...

    Insulation - 1930s Bitumen felt roughcast rendered 1st floor bay wall

    Update. First layer of PIR is in. Either side of the bay area and below void space is a joining cavity wall. Should this be capped/sealed?

    Insulation - 1930s Bitumen felt roughcast rendered 1st floor bay wall

    Sorry, the presence of the impermeable membrane which has bulges (so not a smooth flat surface) has confused me. Firstly, does the cold side need an air gap or not? 1) 85 mm PIR board to account for bulges OR 2) 70 mm PIR which gives about 19mm of air gap. Secondly, stick primarily with PIR?

    Insulation - 1930s Bitumen felt roughcast rendered 1st floor bay wall

    Hi all another one of many insulation threads. I have gotten pretty lost and have struggled searching for insulating information, when dealing with a non-breathable, vapour closed bitumen-like felt membrane. I believe the bay wall is felt with a roughcast rendered finish, no bricks. 1) Bay...

    Internal insulation - 1st floor, single skin bay wall

    Thanks for getting back to me, unfortunately after opening the bay area, the nature of the bay wall and support timber frame has made me re-think how to approach this. UPDATED since original post. After fully opening the bay area, the way I am going to tackle the bay has completely changed...

    Internal insulation - 1st floor, single skin bay wall

    Hi all, a few questions and thoughts. Planning to insulate under a bay window area on the 2nd floor. I have done a rough mock-up of the current bay window area, and with an non-insulated internal wall. The bay protrudes in-front of the house, not covering the cavity space (see image below), so...
