REPLACE EXISTING SKYLIGHT WITH NEW OPENABLE, DOUBLE-GLAZED SKYLIGHT
We have an existing skylight on the upper floor of our two-storey terrace. The skylight is built into a deep skylight shaft recessed into the pitched tin roof.
In summertime considerable heat comes through this skylight - probably because the window of the skylight seems to be made of slightly opaque perspex material (rather than double-glazed glass) and is not openable.
We would like to make the skylight window double-glazed and openable, so that we can open it up on summer nights to release the heat that builds up on the top floor during hot days. This seems a more efficient way of cooling down the house, as it is very difficult to install air conditioning in this house.
We are not looking for a high tech solution: opening up the skylight window with a long pole would be fine if that is cheaper than having an electronic opening, but we would consider either option.
We can't measure the skylight precisely as our ladder doesn't reach that high. However, the window section seems to be approx 450mm x 450mm square.
The top of the skylight is approximately 4.5m above the floor level on the upper storey.
If access from the roof is required (rather than internal access) then the work would need to be done urgently as we are having solar panels installed in two weeks.
