What's the thickness of my Hymer roof?

[jumar]

The company that's supplying my new roofvent have send me a question..
They want to know the roof thickness of the Hymer Tramp 2006 model

I have two options..
1. 35mm to 42mm

2..42mm to 60mm

Any guesses... I'll start. Number 1.

Any more?

Take the inside off and measure thickness

 

[Lenny HB]

It will be either 30mm or 35mm.

 

[gus-lopez]

It supports two of us on the roof without any sign of flexing?
As said either take the trim off inside for measurement or can you get a rough idea without removing it?

 

[Northernraider]

You're correct..its number one . I had the skylights out of my hymer ...it was 30mm .

This might be hard to explain without a drawing but here goes.

Take a piece of cardboard about 12" square. Cut a square hole in the middle about 6" square. Now cut a gap in one side just wide enough to go over the frame of a skylight or vent. Let's call the ends of the board A and B.

Put this over the frame so the top end of the gap (A) just touches the roof. Now measure the distance between the underside of the roof and end B. Subtract this figure from the distance between A and B will give the thickness of the roof.

You may need to increase the size of the bit of cardboard depending on the size of the skylight frame.

Interesting and very scientific method...I have access to a small roofvent in the bathroom...your method might be possible using this.Thank you.

I also fitted a Poynting antenna last year. It came with two different length fittings kit...I needed the longer..
I'll check how much is protruding into the wardrobe and subtract this from the total length.

The supplier in China has asked me via WhatsApp on a couple of occasions today to confirm size... strange She being Chinese and me English both writing in Spanish...

30mm will be the insulation so it will be 33 - 34 mm overall, approx 0.75mm of
aluminium and 3mm of wall board to add to the insulation.

That's going to make the fittings they provide quite precise..
The sales manager I have been dealing with told me they have been dealing with Hymer for 4 years, they supply windows as well as rooflights..
I'll be happy to get this one out, as you have experienced, the mechanism has been a problem for a while..allowing water in and has now rusted up in place..

Tramp 514 GT..
Taking into account all the replies so far, with so many different options to measure... I've decided that 35mm is the thickness..
The roofvent fitting kit is either 35mm to 42mm...or 45mm to 60mm. The latter being a Tank or armoured plated vehicle..
Thank for your photo.
