Weatherizing Caulk

Weatherizing your house is a chore worth attending to. The average unweatherized house in the United States increases the heating bill by 25 to 40 percent, according to the Rocky Mountain Institute, in their book, Homemade Money, How to Save Energy and Dollars in Your Home. Here are some tips for weatherizing your home without adding manmade chemicals, called volatile organic chemicals (VOCs), that can cause a wide range of health problems.

The safest caulk to buy, according to John Bower, author of The Healthy House, is 100 percent silicone, available in most hardware stores. When it dries, it is inert. You can also buy 100 percent silicone “rope” caulk, useful for some big cracks. Make sure to read the labels to make sure there are no added fungicides, as found in products labeled for use in kitchens and bathrooms.

i use the stick-on draught excluder to bridge up any holes in doors and windows as we've recently bought the house and have bigger and more important jobs to do. however, come the spring, i'll be looking andf getting the one window and the front door fitted properly and so there'll be no more holes and the door will be easier to open and lock!

Gandi's home sounds wonderful. But such a light and airy structure would not be enough shelter in climates in the northern USA where winter temperatures are many degrees below freezing for several months a year. India is far warmer than Alaska!

Weatherizing Caulk remind me of what Mahatma Gandhi said: ďAn ideal Indian village will be constructed as to lead itself to perfect sanitation. It will have cottages with sufficient light and ventilation built of material obtainable within a radius of five miles of it. The quarters will have courtyards enabling householders to plant vegetables for domestic use and to house their cattle. The village lanes and streets will be free of all available dust. It will have wells according to its needs and accessible to all. It will have houses of worship for all, also a common meeting place, a village common land for grazing its cattle, a co-operative diary, primary and secondary schools in which industrial education will be the central part, and it will have panchayaths for settling disputes. It will produce its own grains, vegetables and fruits and its own khadi.Ē Mahatma Gandhi's hut in Sevagram was built in this manner with the local available earth, bamboos and bamboo mats. Living in such a hut he could lead India to independence from mighty powers of the world. Living in such a hut the connectivity of his individual spirit with the universal spirit was total with super conductivity. Those living in U.S.A. may not understand this. People like American Journalist Louis Fischer and Social Scientist Ivan Illich who visited Mahatma Gandhi's hut vouch for this. Such a hut is really THE HEALTHY HOUSE. Who cares for it in a material centered world sans universal spirit?
