Carl’s Fencing, Decking & Home Improvements is proud to install ENERGY STAR® certified fiberglass windows. Carl’s Beechworth windows are manufactured to ensure energy efficiency and durability. Unlike traditional windows, Beechworth windows are carefully constructed so their durable fiberglass does not touch metal. This eliminates the metal expansion in the summer during hot months, and contraction during winter months. Over time, consistent expansion and contraction breaks seals and causes drafts.
