Hi I need a flat roof windoe, you only give the opening size, I need to know the size of the base as well, this is the product code CRS8080DDDM, The opening size I need is 750mm x 930mm, the bass is a rased brick edge, so I have 200mm play eather way, so max size would be 950 x 1130, that is the ful

is there any bespoke options? granted it will be more expensive but where can I get one

having a look around, i've seen quite a few brands but still not sure

What brands supply smoke vents for flat roofs?

Can't really be bothered with the fancy electric or solar options just want to save a bit of money
