Hi,
I am considering insulation in order to reduce condensation and keep the boat warmer in winter.   In particular I am looking at the forward cabin and how to fit some insulation to the hull sides and possibly under the deck with material like this... http://www.thermawrap.co.uk/gp_wrap.html.  I used closed-cell foam sheet in a previous boat (similar to a yoga matt), it worked well but did not like being stuck on so perhas thermawrap is better?
 
Has anyone go experience of doing this?
 
Where have you insulated?

The only thing to watch out for is interstitial condensation. This occurs when moist air hits cold face on the outer face of the insulation ie between the insulation & the inner skin of the hull. You need to ensure that all joints are securely taped.

Hi George,
 
Last winter I insulated the forward cabin with similar material ( thermawrap). The steps I took
1. I took of ol the old painting and repainted the bare polyester with a two pot polyurethane.
2. I glued 25 x 25  mm thick oregon pine frames ( shaped to fit the curve)  horizontal to the skin with a 500 mm spacing in between
3. over the frames I stretched the foil using double sided tape
4. screw down varnished oregon pine strips ( 45x10 mm ) due to the shape you have to taper the last two strips to size.
5. I also insulted the ceiling like this only using white painted plywood panels to cover the insulation
6. this spring summer and fall sailed extensively and the condensation is gone.
 
If needed I can send you some pictures
 
Regards
 
Rob
