Your back door is an important entryway into your home. It serves as a connection between your living space and garden or patio, adding practical functionality and long-lasting performance.
You need back doors that can withstand daily use and changing weather conditions in Glasgow. uPVC back doors are a stylish addition to your back entryway that complements the overall look of your home.
What areuPVC Back Doors?
Modern uPVC back doors are made from unplasticized polyvinyl chloride (uPVC). This material isn’t softened during the manufacturing process, allowing it to retain its strength and integrity.
Unlike traditional back doors that rot, swell or warp over time, this material offers excellent weather resistance and durability. Their enhanced energy efficiency also improves the thermal efficiency of your home, perfect for consistent warmth in the colder months.
Made with strong frames and insulated, energy-efficient glass panels, external uPVC back doors provide reliable security. They combine robust features with effortless upkeep that fits perfectly into busy lifestyles.
uPVC back doors only need a wipe down to keep them looking their best. This makes them the perfect low-maintenance option for reliability and resilience against Glasgow’s unpredictable weather conditions.

Why Choose uPVC Back Doors?
Our uPVC back doors are made to measure to ensure the perfect fit for your property. They are ideal for homes in Glasgow, where unpredictable weather conditions demand durable and weather-resistant back doors that are built to last. At RePlace Windows Limited, we offer a large range of uPVC back doors in various door styles and colours to complement your home.
Enhanced Energy Efficiency
Your uPVC doors protect your home, insulating it from heat loss and drafts from outside. Our modern uPVC back doors feature thermally efficient frames and provide a weather-proof seal for consistent thermal performance.
This helps to provide a comfortable environment year-round. uPVC doors are an excellent choice for homeowners seeking a balance of energy-efficient thermal performance and sustainable, long-term value.
Advanced Built-In Security
Your back door plays a crucial role in the safety of your home. Our uPVC back doors feature multi-point locking systems, secure hinges, and reinforced frames for added protection against forced entry. With toughened glass panels, you can enjoy safety and peace of mind without sacrificing natural light.
uPVC’s high chlorine content makes this material naturally fire-resistant. While it doesn’t make it fireproof, it also won’t ignite or spread flames as easily as wooden doors and windows.
Durability & Practical Functionality
uPVC door styles are designed to stand strong against changing weather conditions as well as wear and tear from daily use. They are made with the same high-quality material that ensures they retain the colour, shape and unbeatable strength.
Their low maintenance requirements and their smooth operation make them ideal for busy households with high back door traffic. In addition, uPVC back doors that feature double-glazed glass panels help reduce outside noise, making them perfect for homes in loud or busy neighbourhoods.
