Introduction

Improving the energy efficiency of your home's windows, doors or skylights (known as fenestration products) can substantially improve comfort. It can also reduce your home's energy use and cut down on greenhouse gas emissions that contribute to climate change. Purchasing the best windows, doors and skylights means finding a balance between cost, ease of operation, maintenance, durability, attractiveness and energy efficiency.
