Be patience and wise. Be wise choosing the right solutions. Focus on the maximum quality and lowest possible price, not price only. Especially in the insulation field where quality is required. Lowest price products will require continuous maintenance, which will eventually cost more in the long run.
Be patient with finding the right solution. It is like shopping for a new suit, if you didn’t find what you want in the 1st shop, you can always go and try the next one. The right solution is always there, just keep looking!
