Is a frosted skylight worth installing or does it defeat the object of installing one?
We want to put a skylight in the flat roof of our kitchen and the upstairs neighbour wants to use the roof as a roof terrace. So we've thought of installing a frosted walk-on skylight but not sure if it will let enough light in. Some say it's better as it diffuses the light coming in. Others say it's rubbish as you can't see the sky.
Another option is to put in a long narrow skylight with clear glass (about 350mm by 2000mm) but also not sure if this will let enough light as it's so narrow.
