Window Inserts - Order Online Now

Wish your house was less drafty and your energy bills lower? A simple way to do this is with Window Dressers interior window inserts which have helped hundreds of Upper Valley households enjoy a more comfortable winter home. These inserts are available for purchase once a year. Order now for the 2026 inserts which will be custom-made at our community build to be held at the Church of Christ at Dartmouth in October.

Because our past builds have sold out every year, we recommend ordering as early as possible. Customers who can order, get measured, and pre-pay BEFORE APRIL 2026 will receive 2025 pricing. Subsidies are available for low-income households.

Learn more about the inserts, see sample prices, and place your order at our Windows page here.

This community build is co-hosted by Sustainable Hanover and the Energy Committees of Norwich and Lyme in collaboration with Window Dressers, a Maine-based non-profit which serves Maine, New Hampshire and Vermont. Questions? Email sustainablehanovernh@gmail.com.
