By now, I have already started a few threads, and I hope the introduction doesn’t get boring, but:
We are currently working on renovating our farmstead and owe the carpenter feedback regarding the windows. We have the largest windows facing west (ground floor: two large barn doors will be glazed, two slightly taller pointed arch windows, and five smaller pointed arch windows on the ground and upper floors). I am now considering the heat protection. Initially, I thought about installing Venetian blinds for the two large barn doors. However, due to the pointed arch shape, a full coverage is not possible, and there is always some wind in this area. Then the carpenter suggested solar control glass. For glare protection, we would additionally use pleated blinds. A small canopy is planned in front of the two taller pointed arch windows at some point.
Here are my questions:
1. Will the heat gain be significantly reduced?
2. Will the daylight transmission be significantly decreased, or is it negligible?
Of course, less heat gain is less favorable in winter, but the sun doesn’t shine as strongly from the west during that time anyway.

The following questions:
1. Is the heat gain significantly reduced?
2. Is the daylight transmission significantly reduced, or is it negligible?This cannot be answered generally because solar control glass varies widely in terms of heat insulation and solar protection. It depends on your specific requirements. You need to "experiment" with the values and choose the appropriate glass. You also change the facade appearance if you select highly reflective solar control glass. Various coatings can add color effects—do you want that? Keep in mind that solar control glass is effective even when there is no direct sunlight. You should request samples of different panes, have the performance values explained, and review samples.
So, my pending response: We now have the quote. The additional cost for one large and one small barn door, both glazed, plus four standard windows is just under 1,400 EUR. We will only equip the ground floor with these; the upper floor has only smaller windows. Unfortunately, we need to decide by tomorrow, otherwise the barn doors (aluminum) will increase in price by 11.5% due to a price hike. The window manufacturer requested a sample of the solar control glass, but it has not arrived yet. He said the appearance is the same as the thermal insulation glass, the color is “neutral” and should look like a normal window. I think we will take the risk. It makes me a bit uneasy not having seen it beforehand, but I believe even with the sample glass, the darkening effect caused by the reduced light transmission would be hard to assess. Since this area receives light from three sides, plus additional light from above (steel window from the office into the gallery), I hope that will be sufficient. I will report back in due course.

Again: thanks 🙂 Then we'll probably do it this way. Unless the additional cost is considerable.You can definitely see it. Once looking out from the conservatory with the door half open. So once without the glass, once with it.Even with standard triple-glazed windows, you can notice that it’s darker.
