Loft floor strengthening for telescope

by MACCCA99 » Tue Mar 29, 2022 12:10 am

Hello, I would appreciate any advice on the following:

I want to have a side-opening velux window fitted in my loft, to use a large telescope weighing 70kg.

To support the weight of the telescope I think I would need to have joists added on load bearing walls.

Could the joists be added for a specific width to accommodate the telescope, approx 1 metre, or would the whole loft need to be done?

Thanks

Hi maccca99,
You will need to have joists added so that they are supported on load bearing walls located on the floor below.

Thanks, could that just be for the specific area I want to support, approx 1 metre width, or would I need to install joists for the whole loft?

Hi maccca99,
You only need to fit additional joists for the telescope plus a working area around it. The area you reinforce will depend on the location of load bearing walls. Do bear in mind that the telescope base will need to be rock solid or you will not get a stable image.
