Hello everyone,
We have an end-of-terrace house with a garden facing southwest and are currently planning to cover the terrace. The terrace measures 6 x 3.2 m (20 x 10.5 ft).
The neighbor has agreed to the covering on the condition that it is set back one meter (3.3 ft) from their property and has a maximum depth of 3 m (10 ft). So, the covering would be approximately 5 x 3 m (16.5 x 10 ft).
Another requirement is that we use clear tempered glass so that the covering does not block any light.
My question is whether clear polycarbonate lets through just as much light as clear glass. I might be able to use that as an argument.
Several neighbors also told me that polycarbonate is available with heat protection, whereas clear glass tends to heat up considerably and then requires an additional awning.
Maybe someone could share their experience with me, especially regarding cleaning, appearance, or any other advantages and disadvantages.
Thank you in advance!

But that doesn’t necessarily apply to terraced and semi-detached houses, does it? Or does it specifically apply to closed building layouts in your development area?
Usually, a development plan includes one or two points where exactly that doesn’t happen. This also applies to terraced houses. I have researched this and additionally received this information from the building authority. Even if it didn’t apply, I am dependent on the neighbor, since according to the purchase agreement, even patio covers are actually prohibited. The developer has included this in the contract but does not enforce it. Our neighbor (an investor) is on the developer’s board. If I now do something against the agreement, I can forget about it.
My main concern is actually just the pros and cons of the materials and whether it would be worth discussing polycarbonate. So far, clear glass has been mentioned.

If you choose a pergola awning, it could extend further than the glass roof and provide shade in the evening sun on hot, sunny days.

The price difference between polycarbonate and glass is probably negligible. These polycarbonate panels have become quite expensive.
With both solutions, you will inevitably need additional shading, such as an awning or similar systems.
A rooftop awning starts at around 3,000 euros.

I never understand why acrylic glass is often overlooked for roofing... In terms of appearance, it is closer to real glass than polycarbonate and maintains its look longer (less yellowing), while being more affordable, lighter, and easier to work with than real glass. I believe it is also cheaper than polycarbonate, but I might be wrong or it could depend on the supplier.
Acrylic glass is stiffer than polycarbonate, which makes it quieter and requires fewer cross battens. It is more scratch-resistant, and scratches can be polished out. It is naturally UV-resistant, whereas polycarbonate needs a coating (and once that wears off, you can expect to replace it after one summer, creating a lot of waste).
The only downside is its impact resistance, which is lower, but if the material is thick enough, in my opinion, this is negligible. It is still many times more impact-resistant than real glass. (Polycarbonate: 30 : Acrylic glass: 25 : Real glass: 1).
So if you cannot afford real glass or are worried about the weight, I would always choose acrylic glass.
