March 28, 20179 yr Just about to buy our roof windows, roofer is keen on Fakro rather than Velux. Just wondered is anyone else had a view? Looking at top hung, so as to avoid walking into open, pivoted windows. Now I'm getting tempted by the z-wave remote control functionality of the Fakro one (albeit I think it only comes on pivot ones)... anyone used the z-wave features? Will probably end up with other z-wave elements in the house. Too many options...
March 28, 20179 yr Top hung are rather more difficult to clean outside, especially on a shallow pitch - particularly compared to "Scottish spec" windows (ie are designed to be cleaned from the inside). Bear in mind trees, leaves, access etc. Are you sure Z-Wave is available with Top Hung windows? F Edited March 28, 20179 yr by Ferdinand
March 28, 20179 yr Most of the new stuff is self cleaning glass anyway - in a single storey it's not too bad to reach either from the ground with a pole system.
March 28, 20179 yr All the top hung Fakro rooflights have a u-value of 1.4 W/m2K and it's only the centre pivot where you can get different glazing options to reduce the u-value. Velux allow you to chose the glazing on the top hung windows and therefore the u-values vary depending on the glazing but in general all are all better performing: Velux with Glazing 70 - 1.3 W/m2K Velux with Glazing 60 - 1.2 W/m2K Velux with Glazing 66 - 1.0 W/m2K Velux with Glazing 62 - 0.81 W/m2K Personally I think a u-value of 1.4 W/m2K is poor and you should be looking for better particularly if you've a number of them.
March 29, 20179 yr Author Thanks, @Ferdinand you are correct z-wave is only on the pivot ones. Anyone used the z-wave windows?
