Performance
Energy-efficient performance
Our four-season sunrooms use double-pane insulated glass units with Low-E coatings and argon gas fill. The Low-E coating reflects interior heat back into the room in winter, reducing heating costs. In summer, it blocks a significant portion of solar heat gain to keep the room comfortable. We select glass with the optimal solar heat gain coefficient and U-value for your sunroom orientation and the DMV climate zone.
Comfortable every season
Four-season sunrooms connect to your existing HVAC system or have dedicated heating and cooling. We work with your HVAC contractor to size the additional capacity needed for the glass-enclosed space. Ductless mini-split systems are a popular option that provides both heating and cooling without running new ductwork. Radiant floor heating adds comfortable warmth underfoot during winter months.
Planning
A well-designed sunroom integrates seamlessly with your home and performs beautifully in every season.
South-facing sunrooms get the most winter sun and warmth. East-facing rooms get gentle morning light. West-facing rooms get intense afternoon heat that requires solar control glass. We design the glass specifications to match your sunroom orientation.
Glass roof panels create dramatic light-filled spaces. Solid insulated roofs with skylights balance natural light with thermal performance. Cathedral ceilings, shed roofs, and gable roofs each offer different aesthetics and structural requirements.
Four-season sunrooms need insulated foundations below the frost line. Three-season rooms may use lighter foundations. Existing patios can sometimes be adapted. We engineer the foundation for your specific room type and site conditions.
The transition between your home and the sunroom should feel seamless. We match rooflines, siding, and trim. French doors, sliding glass doors, or folding walls connect the spaces. Proper flashing and weather sealing prevent water intrusion at the connection.
Low-E coatings and laminated glass block over 99 percent of UV radiation that causes furniture fading, artwork damage, and skin exposure. UV protection is built into the glass performance -- no separate films or treatments needed.
Building permits are required in all DMV jurisdictions. We prepare drawings, engineering, and permit applications. We also review HOA architectural requirements when applicable and ensure the design complies with community guidelines.
