Options and standard features
Four-season rooms typically feature a thermally engineered aluminum frame, designed to facilitate efficient heating and cooling while surpassing building code requirements. Homeowners can choose from a variety of frame colors such as bronze, sandstone, white and Black. Additionally, each structure includes an internal electrical raceway to streamline room wiring.
Roof Options:
The most common roof configurations for all-season rooms include:
- Cathedral, vaulted roof: characterized by two sloping roof sections extending from a central point.
- Single slope: consists of a single roof section sloping in one direction.
- Under existing: utilizes an existing pitched or patio roof.
- Roofing materials consist of insulated panels featuring structural interlocking seams and thermal barriers for enhanced strength, stability, and comfort. This flexibility allows for customization of room dimensions according to preference.
Glass Options:
All-season rooms typically feature floor-to-ceiling glass windows and transoms to maximize natural light. While single-pane glass is an option, double-pane glass is preferred for its superior heating and cooling efficiency. Double-pane glass also offers nearly 45% better UV ray protection compared to single-pane glass. Triple coated Low-E glass presents an alternative option, providing enhanced UV blocking and 90% greater efficiency over traditional glass.
Windows & Doors:
Selection of door and window systems depends on the chosen frame material, with aluminum frames favored for their strength and durability compared to composite or vinyl alternatives. Both aluminum and vinyl frames may feature a monorail, though the construction methods differ. Windows equipped with dual sliding interlocking meeting rails offer ventilation and security benefits. Integrated weather stripping enhances draft resistance and weatherproofing, crucial for protection against water infiltration during stormy seasons.
