Still adding insulation ? Cabin_11_08_2019 3_29_46am.mp4

Done ?

Congratulations. Enjoy the ride!

How does that feel, knowing (or at least heavily suspecting) where the money paid to you by one of your favourite clients is coming from?

Sorry, not me.

Welcome @Mischiefsmum Having spent the last 15 years working amongst people going through just what you've been going through, I understand your pain but I also feel your strength, determination and positivity. They are traits that have got you through the last six years, and they'll serve you well as you (literally) build a new life with your daughter. Listen to advice, but trust your instincts - and try to keep a smile on your face ?

If you take a look at my profile pic you'll see we have relatively small areas of glass. Granted, our circumstances are unusual given that night purging is not an option for us, but you'd be surprised just how quickly the temperature rises, even at this time of year (with outside temperatures in the low to mid teens), if the sun is shining and the SageGlass is switched off. If you have large areas of south-facing glazing, the outside temp is pretty much irrelevant if there's bright sunshine.

Hi @Conor, we ordered our SageGlass around 4 years ago now so the price we paid is probably not a reliable indicator of what it may cost today. That said, it's not cheap, but it is (as I've said before) such an elegant solution. We have several tilt and turn windows which it's installed in, but we very rarely open windows so the cables don't get the stressing of constantly being opened and closed. Whether you could install into bi-folds I wouldn't like to say for certain, but each pane requires a separate cable connection so I somehow doubt it. Even if you could, I'd be concerned about the stress those cables would be under with regular opening and closing. What I can say is that SageGlass is very effective, and (at least to our minds) offers significant advantages over other measures for mitigating solar gain.

Or maybe it's just down to how well (or otherwise) it's been installed. As I've said elsewhere, we have a PAUL Novus 300 and you cannot hear it running in any room in the house, even on boost. Sure, if I go out to the plant room, which sits within the footprint of the house but is only accessible from the attached garage), you can hear it running, but none of that noise (or at least none that is discernable) is transmitted through the ducting to the inside.

I'd really get that air test done before going any further.

@Savage87, forgive me if I've missed something earlier in the thread, but have you had an air test on the property? If not, it may be worth doing so before even considering installing MVHR as, if the airtightness is not great, you may find that no MVHR unit is going to work efficiently.

Depends how you're calculating the return. Remember, it's not just the export tariff that you benefit from, but how much of the energy generated you actually use. If you have an ASHP (rather than a gas boiler) you can use the solar generation to power the heat pump and minimise the amount you import from the grid (and the COP of the heat pump will effectively give you circa 3kW output for every 1kW you put into it).

Of course, but I was talking about the 7 panels in the west facing string alone. Those panels are arranged four over three and the lower row of panels fall into shade earlier than the upper row.

Not just useful if you have shading issues, but also if you have panels facing in different directions. We have East, South and West facing panels, and also have minor shading on different panels at different times of the day/year. We have SolarEdge inverter and optimisers and the SolarEdge app clearly demonstrates the benefit in so much that it shows each panel's generation within each 'string'. For example, the west facing string contains 7 panels and the difference between the best and worst performing panel is circa 7% (almost certainly due to shading). Without optimisers the whole string would be limited to the output of the lowest performing panel.

Looks very sharp Moira ? ?

It's all very well having these dark sky areas for you stargazers, but you should be grateful for all the light pollution from towns and cities - how else would those stars be illuminated for you to see them? ?

Blimey, and there was I worrying about three in as many months ?

We've had hits on South, West and East facing windows. The latest, today, resulted in a dead Blackbird. Not even a large pane of glass.

We've done quite a bit to attract wildlife to our garden and enjoy watching a good variety of birds in the hedgerows and at the feeders. However, we've had a number fly direct into our windows, and not just those with SageGlass. Sadly, a few have hit with such force that they've not survived the impact. Does anyone have an opinion as to whether 3G windows attract more bird strikes than single/double glazed, and if so what could be done to mitigate this?

Mrs NSS and I caught up with this episode at the weekend. When it had finished she said, "we are so lucky". "In what way?" I asked. "That we didn't have to borrow for our build" she replied. "That's because we didn't have the ego of the guy in this episode" I said.

Literally can't hear ours running, even on boost. That said, ours runs in Lindab spiral ducting with silencers adjacent to each vent and exhaust fitting. We also 'isolated' the ducting and silencers by mounting on soft rubber blocks to mitigate any vibration/sound transferring to the timber frame/structure. It's so quiet I occasionally hold a tissue against the vents to make sure it's still blowing/sucking!

Ours run vertically into the roof space and then at a variety of angles. We even have a short section that runs horizontally.

Doesn't help in the OP's case, but this is another reason why we went for a warm roof as it avoided the need for the MVHR ducting to be insulated (except where the inlet and exhaust enter/leave the building).

Our stink pipes run up into the roof space and then exhausts via a tile vent. Seems to be standard practice these days.

Either or. We have one fitted vertically but the rest horizontally. Our silencers are a minimum of 60cm long so I'm not sure how anyone could expect them to be fitted vertically between two floors.
