Roof Style
Studio Roof Sunroom
The studio sunroom is a versatile and economical option, ideal for homes with single-story or low roof lines. This style features a simple, sleek roof that slopes in one direction, making it an excellent choice for a seamless extension of your home.
One of the primary advantages of a studio roof is its affordability. The simplicity of the design not only makes it less expensive to construct but also reduces the time and labor involved, potentially lowering the overall project cost. The clean design of the studio roof blends well with a wide range of architectural styles, especially modern and contemporary homes.
Gable/Cathedral Sunroom
The gable roof, also known as a cathedral roof, features a traditional peaked roof with two sloping sides that create a high ceiling inside the room. This design is ideal for adding a dramatic touch to both contemporary and traditional homes.
While the gable roof sunroom is generally more expensive than the studio roof due to its more complex structure and increased materials, the investment is justified by the added value it brings to your home. The high ceilings and grand aesthetic can significantly enhance the appeal of your property. The vaulted ceilings also create a spacious feel, making the sunroom feel like a major addition to the living area.
Ceiling Finishes
Prefinished Ceilings
Prefinished ceilings are an excellent choice for homeowners looking for a high-quality, cost-effective solution. These ceilings are factory-made and come ready to install, which speeds up the construction process and reduces labor costs.
The cost of a sunroom is a major determining factor when choosing how to elevate your home. Luckily at S.E. Wisconsin Sunrooms, we offer cost-effective options during the customization process. Choosing a prefinished ceiling can significantly lower the overall expense of adding a sunroom. The materials and installation are more affordable because they require less labor and are designed for easy assembly. This option is particularly appealing for those who prioritize budget without compromising on quality and appearance.
Wood Tongue & Groove Ceilings
For those desiring a more refined and traditional aesthetic, wood tongue and groove ceilings are an excellent upgrade. This option features interlocking panels that create a seamless and elegant look, enhancing the architectural character of the sunroom.
Wood tongue and groove ceilings are an upgraded option and thus come with a higher price tag compared to prefinished ceilings. The materials are generally more expensive, and the installation requires more skilled labor, which can increase the overall cost of the project.
Knee-Wall Finishes
Prefinished
Prefinished knee walls are factory-made and designed for quick installation. This option is available in various colors and textures to match or complement your home’s interior.
Prefinished knee walls are generally the most affordable option. They offer the convenience of a lower initial investment and reduced installation costs because they are easy to handle and quick to install.While offering a uniform look, prefinished knee walls can also be tailored to meet specific design requirements, providing a balance between cost and customization.
Sided
Sided knee walls are typically constructed with the same materials as the home’s exterior, providing a cohesive look with the existing structure.
Sided knee walls are typically constructed with the same materials as the home’s exterior, providing a cohesive look with the existing structure. This option blends seamlessly with the rest of the home, making the sunroom look like a natural extension of the building. This finish can also provide a more enclosed, private space compared to glass.
Glass
Glass knee walls extend the transparent area from the windows down towards the floor, maximizing the amount of natural light and views of the outdoors.
Opting for glass knee walls can be more costly due to the higher price of glass compared to other materials. However, the investment may lead to higher property value due to the enhanced aesthetic appeal and unique design feature. This option is ideal for those seeking to create a seamless transition between indoor and outdoor spaces.
Windows: Standard
Standard Windows
Picture Windows:
Picture windows are fixed, meaning they do not open. This simplicity makes them one of the most cost-effective options, offering a clear, unobstructed view of the outdoors at a lower price point.
Sliding Windows:
Sliding windows are typically more affordable than some operable windows due to their simple design and mechanism. They provide good ventilation and ease of use at a moderate cost.
Upgraded Windows
Casement Windows
Casement windows are generally more expensive than sliding windows due to their construction and the hardware required for operation. They are hinged at the side and open outward.They provide a clean, modern look with full top-to-bottom ventilation.
Double Hung Windows
These windows are on the higher end of the cost spectrum due to their dual operable sashes, which provide versatile ventilation options.Double hung windows allow you to open either the top or bottom sash, making them excellent for controlling airflow and energy efficiency.
Awnings
Awning windows are similar in cost to casement windows. They are hinged at the top and open outward from the bottom, creating an awning effect. These windows are great for sunrooms, as they can remain open during rain, providing continuous ventilation regardless of weather conditions.
Transoms
Transom windows are typically used as an architectural accent above primary windows, adding to the total cost due to additional framing and installation.They enhance the architectural detail of the sunroom and allow extra light to enter the space without compromising wall space or privacy.
Heating and Cooling Options
In-House Services
PTAC Units
Packaged Terminal Air Conditioner (PTAC) units are self-contained heating and cooling systems commonly found in hotels. These units fit into the wall and provide efficient temperature control for single-room spaces. PTAC units are generally less expensive to purchase and install than comprehensive HVAC systems. They are a cost-effective solution for maintaining the temperature in your sunroom without needing extensive ductwork.
Fireplaces
Adding a fireplace to your sunroom not only enhances the room’s ambiance but also provides a cozy heat source during colder months. We now offer gas, wood burning stoves and fireplaces as an in-house addition. The long-term benefits of a fireplace in your sunroom outweigh the upfront costs.
