Glazing Applications

Glazing for Art Deco Houses

Glazing for Art Deco houses begins with the composition of the building.

Steel frames, curved bays, horizontal window bands and ordered glazing bars establish the rhythm of an Art Deco facade. Their proportions influence how the elevation is read, how light enters the interior and how the solid architectural forms relate to the glass.

Small changes can have a wide visual effect. A heavier frame alters the scale of an opening. A misplaced mullion interrupts the alignment between windows. A replacement installed at the wrong depth removes the shadow that once gave the facade definition.

A successful glazing strategy identifies the architectural role of each opening before selecting a system. Significant original windows may be retained or repaired. Other openings may require carefully proportioned replacements. Contemporary glazing can then improve daylight, thermal comfort and access to the garden while maintaining the character of the house.

IQ Glass works with architects, designers and homeowners to develop glazing for Art Deco houses as part of the complete architectural design. Each system is selected according to the elevation, the planning context, the required performance and the intended relationship between original and contemporary construction.

Early technical input is particularly valuable where a project includes original steel windows, curved glass, a sensitive principal facade or several connected glazing systems. Contact the IQ Glass technical team to discuss the design and performance requirements of an Art Deco property.

The Architectural Character of Art Deco Glazing

Art Deco architecture is controlled by proportion, repetition and geometry. Windows may wrap around corners, reinforce a long horizontal line or sit within strongly modelled areas of masonry and render.

Typical characteristics include:

• Slim steel framed windows
• Horizontal bands of glazing
• Curved glass and rounded bays
• Fine glazing bars
• Stepped or symmetrical window arrangements
• Carefully balanced areas of solid wall and glass
• Openings aligned with parapets, balconies and projecting architectural forms

These elements work together across the elevation. The position of a glazing bar affects the balance of the window. The depth of the reveal creates shadow around the frame. The alignment of openings across different storeys establishes order and continuity.

Frame dimensions therefore form only one part of the specification. Material, colour, opening configuration, perimeter detailing and installation depth also shape the finished appearance.

The most successful glazing for Art Deco houses preserves the hierarchy of the facade. Principal windows retain their prominence, secondary openings support the composition, and contemporary additions remain clearly connected to the wider architectural idea.

Planning, Conservation and Existing Windows

The planning status of the property should be established before new glazing is specified.

An Art Deco house may be listed, located within a conservation area or affected by an Article 4 Direction. Original steel windows, curved bays and characteristic glazing patterns may also hold architectural value on properties without formal protection.

An initial assessment should record:

• Which windows and doors are original
• Which elevations carry the greatest architectural significance
• How the glazing relates to the proportions of the facade
• Whether later replacements have altered the composition
• Which frames remain suitable for repair
• Where contemporary glazing can be introduced sensitively

Many projects benefit from a clear hierarchy of intervention. Original or architecturally significant glazing can be retained at the front and on prominent side elevations. Larger contemporary openings can then be concentrated at the rear, where they support a new relationship with the garden and internal living spaces.

This approach allows the original house and the new work to remain legible. The existing architecture keeps its visual authority, while the extension develops a contemporary language based on compatible proportions and alignments.

IQ Glass has experience delivering architectural glazing for listed buildings and sensitive historic properties. Early involvement can help architects define the boundary between retained fabric, replacement glazing and new interventions before planning and construction details are fixed.

Retaining and Replacing Original Steel Windows

Original steel windows often contribute significantly to an Art Deco elevation. Their narrow profiles, glazing bar patterns and opening arrangements can be difficult to reproduce with a standard replacement system.

Where the existing frames remain viable, the project team can assess the potential for repair and upgrading. Appropriate work may include localised steel repairs, renewed seals, replacement panes, refurbished ironmongery or carefully detailed secondary glazing.

Secondary glazing can improve thermal and acoustic comfort while preserving important external frames. Its success depends on the depth of the internal reveal, ventilation requirements, access for maintenance and the visual relationship between the original and secondary windows.

Where replacement is required, the existing elevation should be surveyed in detail. The survey should record frame widths, glazing bar positions, opening configurations, reveal depths and junctions with the surrounding wall.

Modern steel window and door systems can combine fine profiles with improved weather resistance, security and insulated glass specifications. The Mondrian steel glazing range can be developed with bespoke frame layouts, finishes and opening arrangements to suit the architecture of the property.

The quality of the replacement depends on the drawing, the proportion and the installation detail. Product selection follows from those decisions.

Contemporary Extensions to Art Deco Houses

The rear elevation often provides the greatest opportunity for contemporary glazing.

Many Art Deco and 1930s houses contain generous rooms with a limited relationship to the garden. Later additions can restrict daylight, fragment the plan or create awkward junctions between the original house and external space.

A well designed extension can improve these conditions through a deliberate arrangement of sliding doors, fixed glazing, rooflights and solid architectural elements.

Broad sliding openings often complement the horizontal emphasis of Art Deco architecture. Roof glazing can introduce daylight close to the original rear wall, where an extension may otherwise deepen the plan. Steel framed doors can add rhythm and definition to an elevation that requires more articulation.

The Netherford Road project demonstrates how contemporary glazing can transform the rear of an Art Deco house while retaining a strong relationship with the original architecture.

The extension can take cues from existing parapet lines, structural bays, window proportions and changes in level. These references create continuity without copying historic details.

Technical coordination determines the clarity of the finished result. Sliding door frames, roof glazing, primary structure, drainage and surrounding finishes should be developed together. The threshold, head and jamb details have as much visual influence as the nominal sightline of the system.

IQ Glass can coordinate these elements as one architectural glazing package. This allows the interfaces between sliding doors, structural glass and steel systems to be resolved within a consistent design process.

Choosing Glazing Systems for Art Deco Houses

Different parts of an Art Deco property place different demands on the glazing.

The principal facade may require fine steel profiles and carefully ordered glazing bars. A rear extension may need large sliding panels and concealed frames. A deep plan may benefit from roof glazing and internal screens.

A coordinated strategy allows each system to perform a clear architectural role.

Steel Framed Windows and Doors

Steel framed glazing suits elevations where the frame contributes visibly to the composition.

It can be used for replacement windows, entrance doors, contemporary extensions and feature elevations. Frame layouts can follow the proportion of the original openings or establish a new rhythm within a clearly contemporary addition.

Colour should respond to the building, its materials and any surviving original finishes. Dark frames often reinforce the graphic quality of Art Deco architecture, although the final choice should come from the specific property rather than a general period reference.

The Mondrian steel window and door range can be configured around bespoke opening arrangements, glazing bar layouts and finishes.

Minimal Sliding Glass Doors

Minimal sliding glass doors can create long views and generous access to the garden while supporting the horizontal character of an Art Deco house.

Panel divisions should align with the architecture. Mullions can follow structural bays, internal walls or other significant lines across the elevation. Concealed head and jamb frames reduce visual interruption, while a flush threshold strengthens the connection between internal and external floor finishes.

The final composition should remain balanced with the doors open and closed. Panel width, opening direction and the position of fixed panes all contribute to the appearance of the elevation.

IQ Glass can develop the sliding door configuration alongside the structure, drainage and surrounding finishes, allowing the system to be integrated into the architecture from the outset.

Structural Glass

Structural glazing introduces daylight and connection with minimal visible framing.

Structural glass roofs can illuminate the junction between an original house and a new extension. Frameless glass links can create a visual separation between historic and contemporary construction while maintaining physical continuity.

Fixed structural glass can also complete corners, form glazed returns or reduce the apparent weight of a new addition.

Each structural glass element should address a defined spatial or environmental requirement. Its position, support, drainage and glass specification should be coordinated with the wider building design.

Internal Steel Glazing

Art Deco houses often contain deep plans and a sequence of enclosed rooms. Internal steel framed doors and screens allow daylight and views to travel through the interior while preserving acoustic and spatial separation.

The frame layout can respond to the proportions of the external windows, creating continuity between the facade and the internal architecture.

Internal screens are particularly effective between kitchens, halls, studies and living spaces. They retain definition between rooms while making the plan feel brighter and more connected.

A Daylight Strategy for Art Deco Houses

The position of the glass determines the quality of the daylight.

A large rear opening can provide a broad garden view and strong daylight close to the facade. Roof glazing can bring light farther into the plan. Internal screens can allow that light to continue into adjoining rooms and circulation spaces.

A coordinated daylight strategy may combine:

• Sliding doors for views, access and low level daylight
• Roof glazing close to the original rear wall
• Fixed glass at corners and returns
• Internal screens for borrowed light
• High level glazing where privacy is required

Each element contributes differently. Their combined effect creates a more even distribution of daylight and a stronger visual connection through the house.

The Goscote House project uses roof glazing, a glass link and slim framed systems to connect historic fabric with contemporary living spaces.

Effective glazing places glass where it changes the experience of the building. The overall area of glazing matters less than its relationship with the plan, the orientation and the architectural form.

Thermal, Solar and Acoustic Performance

Modern glazing for Art Deco houses must support the environmental requirements of the property.

Frame systems, glass specifications and perimeter junctions should be developed in relation to the orientation, location and use of each space.

Relevant considerations include:

• Insulated glass units
• Thermally broken frames
• Solar control glass
• Acoustic laminated glass
• Safety glazing
• Security requirements
• Ventilation
• Condensation risk

Large south and west facing elevations may require solar control coatings or external shading to manage summer temperatures. Roof glazing receives a different pattern of solar exposure and often requires a separate glass specification.

Acoustic performance depends on the full facade construction. Laminated glass, insulated unit build ups, frame seals and installation details all contribute to the result.

Thermal performance also relies on the relationship between the glass, frame and surrounding wall. Junctions should be assessed for insulation continuity and condensation risk during the technical design stage.

IQ Glass can review glass dimensions, frame systems and proposed build ups as part of the architectural glazing package. This allows appearance, comfort and regulatory requirements to be developed together.

Coordinating the Complete Glazing Package

A coherent Art Deco renovation may include several distinct glazing systems.

Original steel windows can remain at the principal elevation. Modern steel replacements can be introduced where existing frames have reached the end of their serviceable life. Minimal sliding doors can open the rear to the garden. Structural roof glazing can bring daylight into the centre of the plan, while internal screens distribute it through adjoining rooms.

The systems differ, but the same design principles connect them:

• Controlled proportions
• Clear alignments
• Consistent frame and glazing bar relationships
• Carefully resolved thresholds and perimeter junctions
• Glass specifications suited to each orientation and space
• A deliberate balance between solid construction and transparency

Coordinating these elements through one specialist glazing package helps resolve the interfaces before installation. It also gives the architect greater control over how the systems relate across the building.

The finished house should read as one architectural composition, with every glazed element contributing to the same idea.
