Premium UPVC Windows and Doors for Islington's Distinctive Properties
Durajoin, Islington’s trusted manufacturer and supplier of premium UPVC windows and doors, has proudly served this dynamic borough for decades. From the elegant Georgian terraces of Canonbury to the stylish modern apartments of Angel, our bespoke double glazing solutions offer exceptional durability, thermal efficiency, and aesthetic flexibility to enhance any Islington property.

Why Islington Homeowners Choose Durajoin Double Glazing
Islington’s architectural landscape is a captivating blend of historic charm and contemporary innovation. From the grand Regency and Victorian homes of Barnsbury to the sleek conversions near Upper Street, the borough demands windows and doors that harmonize with diverse styles while tackling urban challenges.
Islington’s bustling streets, proximity to transport hubs like King’s Cross and Highbury & Islington, and exposure to city pollution require robust solutions. Our advanced UPVC double glazing systems protect homes from noise, weather, and rising energy costs—a key concern for Islington residents facing high utility bills. The borough’s lively atmosphere, with vibrant nightlife and busy roads like Holloway Road, can generate significant noise, but Durajoin’s premium double glazed windows deliver superior sound insulation, creating peaceful retreats. Our enhanced security features provide reassurance in Islington’s varied neighborhoods, where safety is a priority.
UPVC Double Glazed Windows: Popular Styles for Islington Properties
Casement Windows in Islington
Casement windows, our most versatile style in Islington, feature side-hung sashes that open outward, offering excellent ventilation and uninterrupted views. Their clean design complements both the modern flats of Clerkenwell and the period properties of De Beauvoir. For Islington’s many Georgian and Victorian homes, we customize casement windows with Georgian bars or Astragal patterns to preserve heritage while ensuring modern efficiency. In the borough’s contemporary lofts and new-builds, minimalist casement designs maximize light—crucial in Islington’s often narrow streets.
Sash Windows in Islington
Our UPVC sash windows celebrate Islington’s architectural legacy, replicating the refined look of traditional timber sashes found in conservation areas like Angel and Highbury. Ideal for Georgian, Victorian, and Edwardian homes, these windows feature two sliding sashes for flexible ventilation, with modern upgrades like hidden security features and tilt mechanisms for easy cleaning—perfect for Islington’s multi-story terraces. They eliminate drafts and sticking, ensuring comfort in the borough’s older properties.
Tilt and Turn Windows in Islington
Tilt and turn windows are gaining traction in Islington’s renovated homes and modern developments, offering dual functionality: tilting inward for secure ventilation or opening fully for airflow and easy maintenance. These windows are popular in new builds near King’s Cross and canal-side apartments in City Road Basin, where practicality and safety are key. Cleaning both sides from inside is a major benefit in Islington’s growing number of mid-rise flats.
Bay and Bow Windows in Islington
Bay and bow windows are defining features of Islington’s Victorian and Edwardian homes, particularly in areas like Tufnell Park and Canonbury. Projecting outward, they create extra interior space and flood rooms with light—ideal for the borough’s narrow terraces. These windows boost curb appeal while forming cozy nooks for dining or relaxing with views of Islington’s leafy streets. Our UPVC versions enhance thermal performance, addressing the draftiness common in the borough’s historic homes.
Premium UPVC Doors: Enhancing Islington Properties

Durajoin’s UPVC front doors combine sturdy construction with customizable designs to suit the borough’s diverse styles—from the ornate terraces of Barnsbury to the modern flats of Finsbury.

Anti-lift mechanisms and toughened glass ensure security, especially for ground-floor installations in Islington’s residential areas.
French Doors in Islington
French doors add sophistication to Islington’s period conversions and modern homes, with twin leaves that open outward to connect gardens, balconies, or interiors. Common in areas like Islington Green and St. Peter’s, they enhance light and airflow. Our UPVC French doors combine slim sightlines, robust hinges, and weathertight seals, with optional decorative glazing to match Islington’s blend of classic and contemporary aesthetics.
Bifold Doors in Islington
Bifold doors are a standout feature in Islington’s thriving renovation market, creating wide openings to gardens or patios in areas like Lower Holloway and Canonbury. Their concertina-style panels transform narrow Victorian terraces, connecting interiors to outdoor spaces. Despite their expansive design, our bifold doors maintain excellent thermal efficiency, helping Islington homeowners save energy while adding modern flair to traditional homes.

Enhanced Security for Islington Properties
Security is a priority in Islington’s diverse neighborhoods. Our UPVC windows and doors include:
- Multi-point locking for multiple frame contact points
- Internal glazing beads to prevent external glass removal
- Reinforced frames and sashes to deter break-ins
- High-security hinges and handles with anti-tamper features
For higher-risk areas or valuable properties, we offer laminated security glass, anti-snap locks, and smart home integration, ensuring Islington residents feel safe without sacrificing style.
The Advantages of Choosing Customized UPVC Double Glazing in Islington
Superior Thermal Efficiency for Islington’s Climate
Islington’s urban heat island effect and fluctuating weather make insulation essential. Our UPVC windows and doors feature multi-chambered profiles and high-performance double glazing, reducing heat loss by up to 40% compared to single glazing. This saves energy in Islington’s older terraces and high-rise flats. For exposed properties near busy roads or canals, we offer triple glazing and low-emissivity coatings for enhanced comfort.
Noise Reduction in Islington’s Vibrant Environment
From the hum of Upper Street to train noise near Highbury & Islington, the borough’s soundscape can disrupt daily life. Our double glazing systems use multiple glass layers and gas-filled cavities to block sound, with precision frames eliminating gaps. For homes near noisy spots like Holloway Road or King’s Cross, we provide acoustic packages with laminated glass and extra sealing for added tranquility.
