I am looking at my plans and to date I have been able to work out what all the acronyms stand for ... however on my last set of plans the builders have added a few more, that I can not work out for the life of me.
RH - This is something on the outside edge of the house, there are 2 of them at the front of the house and they seem to only effect the ground floor
SPR - I have 6 of these, again they are place on the outside edge of the home. These only seem to be on the first floor.
Thanks
