Jimbouk 10 Posted March 28, 2017 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... Share this post Link to post Share on other sites
Ferdinand 1,676 Posted March 28, 2017 (edited) 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, 2017 by Ferdinand Share this post Link to post Share on other sites
PeterW 2,470 Posted March 28, 2017 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. Share this post Link to post Share on other sites
Dudda 104 Posted March 28, 2017 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.

Jimbouk 10 Posted March 29, 2017 Thanks, @Ferdinand you are correct z-wave is only on the pivot ones. Anyone used the z-wave windows? Share this post Link to post Share on other sites
