Seal between conservatory roof and frame (Willab Garden)

[Zeeker]

Hello,
I have built a sunroom from Willab Garden with an insulated roof.
As one of the final steps, you are supposed to place wooden cover strips between the roof and side beam, roof and ridge beam, roof and gable wedge.

I think it doesn't seem like a neat solution.
I'm considering using expanding window seals instead as sealing. At least between the gable wedge and roof where there is a 7 mm gap.

Does anyone see any danger with this or have any other suggestions?
Thanks in advance.

Understand your thinking, the problem might be that you get a black surface that can become hot, and the roof may become too warm. It may also be visible from outside depending on how your roof slopes. Give willab a call and check what their product specialist thinks.

Hello, I have exactly the same problem.
How did you solve the sealing? Anyone else with suggestions?

Glass wool or mineral wool should not be in contact with the channel plastic according to willab.

Maybe using something like foam plastic instead could work...

Well, expanding sealant strip was too fiddly.
I am going to go with the wooden strips as originally planned.
Possibly with silicone sealing.

Same consideration after just finishing building. You probably won't get it tight if you put wooden strips around it?? How did you end up doing it???

Hi, haven't found a sustainable good solution. You want air in the summer and sealed in the winter.

one could put a vetnil in the gable wedge I thought... something must be done about the gaps. I've chosen 40mm roofing and spring/autumn+ glass to be able to maximize the season, so I don't want it to be open 1cm all around... it loses the point of having insulating items. According to Willab's instructions, there's nothing mentioned about this other than that you should put the strips. Do you cut out for the aluminum rails then you think?

you can install a vetnil in the end wedge I thought... something must be done about the gaps. I have chosen a 40mm roof and spring/fall+ glass to be able to maximize the season so then I don't want it to be open 1cm all around..... kind of defeats the purpose of having insulating items. According to Willab's instructions, it doesn't say anything about this other than to install the moldings. Do you notch out for the aluminum tracks then you think?

I have built many conservatories of different brands and agree with you that where the roof meets the front beam/rear beam, it is prone to cold drafts. Santex has an extra rubber strip that is installed on the front beam before the roof is put in place. Willab has nothing except the inner wooden molding that you make a notch in so it connects to the roof as the roof tracks otherwise hit.
For insulated conservatories, I lay swelling tape (outside the manufacturer's descriptions) on the front beam and rear beam between the roof tracks and then put on the roof. Then you have insulated as best as possible in these constructions.

Okay but now I've already installed the roof so I have to insert something into the gap afterwards and then attach the trim. This should work reasonably well (better than nothing at least...). It's unfortunate to even need these trims but well, I guess I'll have to live with it. Is there any material that should NOT be used? I seem to remember reading somewhere that channel plastic shouldn't come in contact with something??

Otherwise, I'm thinking about a white or transparent P-trim.

Ok but I've already put the roof on, so I have to insert something into the gap afterward and then put on the moldings. This should work fairly well (better than nothing at least...). It's a shame to even need these moldings, but I guess I'll have to live with it. Is there any material that you should NOT use? I remember reading somewhere that kanalplast should not come into contact with something??

You can insert an expanding foam tape afterward as well.
For example, a narrower sealing strip like this one.

And then on with the wooden moldings.

Okay, but this one is black? I don't know how important it is, but you don't want to see black stripes from the outside and from a temperature perspective, it's not okay with anything other than white/transparent.

Do you know if there's something you're not allowed to use??

Anyone tried black edge trim against channel plastic from Willab??? Does it work?
