<p>I live in Brooklyn in a brick house. I have air conditioning and heat but there are still big fluctuations in temperature due to the changing seasons. When it is 80 degrees outside in summer it is 75 degrees in that closet. I don't want to air condition the whole house for my negatives in the closet to be cool. Also if it is humid outside it can get humid in the house. There is no central air-conditioning in my house. My negatives are my life! I want to protect them.</p>
