Framing Systems
Each of our framing systems is handcrafted from premium bronze extrusions which we refine into original showpieces that last a lifetime. We take great pride in everything we build and offer a complete package of frame, glass and hardware with every window style. Our windows and doors are much more than functional design additions – they are a luxury for any interior space.
Thermally Broken frames are our most popular offering, and for good reason. Essentially, these frames are engineered to better regulate the temperature between indoors and outdoors using what’s called a thermal break. Though windows are naturally inefficient insulators, Thermally Broken frames change that through clever and effective design. A thermal break acts as a barrier between the inside and the outside of a window frame – reducing heat transfer from one side to the other. Whether it’s the scorching heat of Phoenix in the summer or the sub-zero temperatures of winter in Maine, Thermally Broken window frames keep interior living spaces comfortable and consistent.
We’ve worked tirelessly to refine a product that is truly unique. Unlike many other manufacturers, our frames are constructed from genuine solid bronze with an authentic thermal break. In fact, there are very few metal windows available with true thermal breaks. When combined with bespoke workmanship and tailored design elements, our Thermally Broken frames are the clear choice. This style of frame is most commonly used on:
- Sliding Doors
- Front Doors
- Window Walls
- Fixed Windows
- Folding Doors
- Casements
Renaissance Genuine Solid Bronze has the privilege of manufacturing and supplying products to heritage homes and buildings, which is why we also offer Non-thermally Broken window frames. Though these frames do not regulate heat as effectively as their more popular counterparts, they are the ideal choice to complement historic architecture and traditional interior spaces. Our Non-thermally Broken frames are constructed and styled similarly to our Thermally Broken frames but use monolithic glass. This gives the frame a more historic visual appeal to seamlessly match the aesthetic of spaces like century homes and historic buildings. This style of frame is most commonly used on:
- Fixed Windows
- Folding Windows
- Window Walls
- Casements
Mullions, Muntins & True Divided Light
All of our complete window packages use the highest quality materials and premium construction methods to create systems befitting the most upscale spaces. Our fixed windows, window walls and sliding doors use a choice of factory or field mullions to create undeniably luxurious products. These mullions join multiple panels of tempered Low-E glass together with narrow bronze extrusions to create window systems with narrow sightlines for impressive views.
In addition, Renaissance Genuine Solid Bronze windows feature authentic integrated muntin bars for a coveted design aesthetic that also achieves True Divided Light. Our muntin bars separate each piece of tempered Low-E glass within a window system, allowing each piece to have a distinct reflectance. This subtle distinction adds an authenticity that cannot be achieved by using a single pane of glass. True Divided Light windows reduce the size of each glass unit to also reduce the likelihood of glass breakage.
Though many windows use what appear to be integrated muntin bars, these are merely visual accents placed on the window’s exterior to create Simulated Divided Light. In contrast, our expert craftspeople carefully assemble each window by hand using premium glass and integrated muntin bars. Creating something beyond compare – genuine bronze windows with True Divided Light.
Waterproofing
We use a signature waterproofing system throughout all of our exterior windows created for punch openings, that is, standalone windows sitting within a wall. Our unique Z-Fin design embeds the window and door waterproofing system directly into the surrounding surfaces. This creates a distinctive architectural appeal with very narrow sightlines while directly sealing into the building’s waterproofing system. The Z-Fin also connects the window and door’s glass and frame to the waterproofing material used on the walls – forming a continuous waterproof barrier throughout. Our distinctive frames are set in a copper Drain Pan, which catches any moisture or condensation. Moisture captured is channelled outside the building through a Water Diverter, protecting the structure from mold, moisture and mildew.

Frequently Asked Questions
How much more efficient are thermally broken bronze windows compared to non-thermally broken ones?
Thermally broken bronze windows offer significantly better insulation than non-thermally-broken frames. A thermal break reduces heat transfer, helping homes stay warmer in winter and cooler in summer while limiting condensation. This is particularly important for energy efficiency in locations with extremes of seasonal temperature – very hot or humid in summer, and/or very cold in winter. We use polyamide strips to create our thermal breaks, as opposed to the pour and debridge method. The strips fit tightly into our custom extrusions and are highly resistant to cold shrinkage, ensuring optimal performance over many decades.
What finishes are available for bronze windows and doors, and how do they change over time?
Bronze windows and doors can be finished in a variety of ways, from natural, brushed finishes to custom patinas in many distinctive shades. We also work with specialist third parties to provide additional finishes such as powder coating and metal plating – this means you can match individual bronze fenestration units to other windows, doors or installations.
Over time, bronze develops a natural patina that enhances its depth and character without compromising performance. Natural bronze typically darkens to a rich chestnut brown, but our custom patina finishing enables you to achieve shades of charcoal and slate gray. If you choose a natural finish, the color change will be more dramatic over time. If you choose one of our darker patina finishes, the changes will be more subtle and predictable.

How resistant is bronze to weathering, corrosion, and coastal environments?
Bronze is highly resistant to weathering and corrosion, even in humid or coastal environments. To give an idea of its corrosion resistance, bronze is the metal of choice for marine components and ship propellers that spend most of their lifespan submerged in sea water.
On land, natural bronze patina protects the underlying metal from oxidation and salts so it will never rust or corrode. Combined with tempered glass installed using the wet glazing method, our solid bronze windows also have a degree of flexibility that helps them withstand extreme winds that can be a feature of coastal environments.
What are the cost differences between bronze windows/doors and steel or aluminum frames?
Bronze windows and doors do cost more than alternatives like steel, aluminum or wood – typically around 15-20% more expensive than premium steel, for example. But these additional upfront costs are offset by significant benefits including unmatched durability, a longer lifespan and lower ownership costs over time. While cheaper materials may need to be replaced within decades, bronze lasts for generations – and while materials like steel need regular repainting to protect against corrosion, bronze endures decade after decade with minimalo maintenance costs. We have also launched an annual service program for our bronze fenestration systems – a Renaissance specialist will visit your property, inspect all your windows and doors, ensure all moving parts are in good condition and carry out routine maintenance on request.
