Hi all, I need to coat aluminium profiles with some kind of rubber in order to minimise the heat transfer through them, but I dont know any product that can do a thermal barrier. Any recommendation about product and process?
How do you want to apply the coating? Spray on/layer/sheet/glue etc?

The aim is to limit the heat loss from the house interior to the exterior, because aluminium is good in transfering the thermal energy to outside and vice versa. The rubber improves tactile feedback and minimizes heat loss.
This aluminum used how? Unless the rubber, or whatever, coating is quite thick, its insulation value will be pretty marginal, compared to something intended to insulate a house.
There are other approaches besides a solid material. Thin (>13 mm, <20 mm) air gaps work tolerably well; fiberglass insulation is mostly air, when you get right down to it. It's basically an air gap that is prevented from convecting by the fiberglass. Air has an R-value of about 5.5 per inch of thickness, assuming no convection.
