About ELC
A four season sunroom is an almost-outdoor living space designed to be used throughout the entire year. These add-ons are integrated into your home’s heating and cooling system, and are fully insulated. This allows for temperature control and comfort in any season. ELC’s four-season sunrooms feature high-performance sunroom windows and doors to maximize natural light and maintain energy efficiency.
Your four season room is designed to be used 365 days a year, rain or shine! Fully insulated and heated/cooled just like any other room in your house. You’ll enjoy being closer to nature in a temperature controlled environment.
Air-sealed sunroom windows and doors protect your sunroom against the elements, while your home’s existing HVAC system does the work of heating and cooling your new space. Fully insulated roof, floor and walls ensure your four season sunroom is energy efficient.
Aluminum or vinyl framing are popular choices in four season room builds. Sunroom windows and doors are made of high-quality insulated glass.
In most cases, you will need a permit to build a sunroom. ELC will take care of filing these for you. We will also help with any necessary HOA paperwork.
