    cross ventilation and issues with roof design with lantern

    I did ask him why some of the sizes are odd. Like 50mm width not nominal sizes like 47mm. He said its the software. So just to touch on the downlight issue. I take it the issue is the mineral wool is in the way, and once its cut free and clear of the spots, we now have cold spots? Or is it the...

    cross ventilation and issues with roof design with lantern

    I wonder if its worth asking my pointed bco? Best of it is i have paid for this design, and also got the superfoil stuff already and that was £400. Nuts Can anyone see a reason as to why the flitch beam would be 2x 195mmx50mm when trimmers t1 and t2 are 200? Is it just me or does that seem odd?

    New ground floor svp air admittance

    Its a fair point and one i was a bit worried about but i thought as it was by the chamber it would be passable. They need to pass the footings off so i can get advice then. I did have a play with the angles the other day but something always got in the way. That boundary box! I think if...

    New ground floor svp air admittance

    Hi hugh. I fully agree i should have taken it that way looking at it from what you have said. I know what iv opted to do here isnt the best route. But it saves me digging my drive up as its shared and since the clay didnt break iv opted to go this route, i hope it dont bite me in the a** i could...

    New ground floor svp air admittance

    A little oversight. I didnt realise you could not use a side entry into a chamber if the rear entry point of the invert level was not in use for the main run. As i have it in the picture, both toilets are branched into a side entry. Going to have another look today. If i can rotate my base i...
