A: Yes, the window can be bolted to any material including OSB, chipboard, tongue & groove, or wooden planks.

Q: What about structural integrity?

Q: Do I need any special tools or skills to fit one?
A: No special skills or tools are required, and any competent DIY’er can install the window in less than 2 hours.

Q: Do I have to climb on the outside of my roof to install?
A: No, you definitely don't need to climb on your roof, the window can be entirely installed from the inside.

Q: Where is the best place to fit my window?
A: Ideally, as near to the top ridge line as possible. Make sure it doesn't cross a vertical joint in your felt line or clash with an internal purlin.

A: Yes, you don't need any additional sealant or glue to install the skylight as it comes with an oil based compression gasket which ensures a good seal.

Very Good... and a better product than I expected! ★★★★★ The powder-coated aluminium unit is solid and heavy, and the the glazing is very rigid (I thought it was glass when I saw it, but apparently it's thick acrylic). The window unit is supplied pre-assembled in factory, and is well made. The wooden trims and and facings are pre-cut and pre-mitred for a neat finish inside, however this is somewhat spoiled by the bolts protruding down into the shed. I opted for the longer 50mm bolts just in case, however I'm now left with long ends that need to be cut, although I'll probably never get round to doing this! The skylight was straightforward enough to fit, but you need to be fairly precise when cutting the hole as the bolts are only about 10mm from the hole. You also need to make sure that your roofing felt doesn't flap about as you cut it, as you definitely wouldn't want it to get damaged. Basically the shed roof is sandwiched between the inner and outer parts of the skylight, so you need to make sure that the bolts are tightened down firmly and evenly. There is a sticky compression seal around the window that stops the rain getting in. I wasn't confident about how watertight this would be, however I've tested it with the garden hose and it works fine. All-in-all, I'm very pleased with the skylight and I'd buy it again. It took a couple of hours to fit, but I'm sure it won't take as long the next time.
