A hands-on workshop on the construction of interior insulating storm windows will be offered on Saturday Oct. 23, from 1 to 4 p.m., at the American Legion Hall in Camden at 91 Pearl St. It will be led by Woolwich artist/engineer Guy Marsden, a member of the Midcoast Green Collaberative. The workshop is cosponsored by the Camden American Legion Post 30 and Green Sneakers, a weatherization project initiated by the the Sierra Club Maine Chapter and the Maine Counsel of Churches.

Participants will go through the steps of building removable wood framed inserts, which are covered with plastic film on two sides and designed to fit into the inside of your existing windows. They are easily removed for storage during the summer. Made from readily available materials, they are inexpensive and simple to make, and help considerably in reducing heat loss through the windows. The cost of the windows could be recovered in just one heating season in reduced fuel. Investing in weatherization offers a quick return in our climate, with our old leaky housing stock, and the strong likelihood of rising fuel prices. Weatherization is one of the best investments you can make these days.

The workshop is free, but donations would be appreciated for the cost of materials.The workshop is limited to 30 participants. Refreshments will be offered. Call to register, 236-3561 or 236-8732; wgrantg@localnet.com or beedyparker@gwi.net.
