I need help! I dont know which is the best thermal house insulation for the outside part of my house, which is made of of concrete and bricks. I want to know which insulation could resist against the lowest temperature. Please help me!! I would really appreciate it.

Insulation is measured by "R" factor, meaning resistance to heat transfer. The most "R per inch" in typical insulation materials is probably isocyanurate foam board, which is about R-11 per inch.

The best type of insulation would largely depend on how your house was built. For a brick house read these articles:
http://www.askthebuilder.com/610_How_to_Insulate_an_Older_Brick_Home.shtml
http://www.thisoldhouse.com/toh/tvprograms/asktoh/qaarticle/0,16588,213094,00.html
The R value of insulation is for the most part dependent on the thickness of the space available for the insulating material. The installation in an existing structure is usually done by blowing in a insulation material through holes in the interior wall. The holes are then patched/painted which if done properly one cannot detect that any work had been done.
As pointed out in both article above not much is gained from insulating existing brick structures. Insulating the roof area, insulative windows, and caulking/weatherstripping are areas that can add significant gain to overall insulation.

If possible, you can insulate with a 1/2 lb. SPF (spray polyurethane foam) - which has a high R value as well and provides high energy savings in the summer as well as winter.
Easiest way to install is with new construction - the foam is sprayed in liquid form between the studs in the walls - it instantly turns into a rigid foam and fills in any open spaces.
While SPF may be more pricey than other systems - it will pay for itself in energy savings within a few years.
Good luck!

Several factors
1. What zone are you in? Takes less insulation in MD that it does Caribou ME.
2. How thick are the studs? IE 2x4 studs the mac is R11
3. If it cement you need a thin air chanle to handle the moisture
4. Is this above ground or below ground ?

Insulation is measured by "R" factor,higher the better

The best would most likely the spray on foam because it seals every crack and crevis. Its used in refrigeration buildings and all type of controlled climates.
