Coloured uPVC Windows & Doors: Colour Options, Finishes & Fade Resistance

Coloured uPVC doors and windows offer modern aesthetics with high-performance insulation, durability, and low maintenance. While the white frames remain standard, there is huge demand for coloured uPVC from homeowners, architects, and builders in modern construction. These coloured profiles derive their colour through foiling (lamination) and co-extrusion techniques.

This article explains what coloured uPVC windows and doors are, their colour options, benefits, comparisons, and maintenance, to help you make the right decision.

What Are Coloured uPVC Doors And Windows?

Coloured uPVC windows and doors are unplasticized polyvinyl chloride profiles, laminated with specialised, bonded colour foils or painted finishes. They come in modern solid finishes, woodgrain finishes, dual-colour finishes, and vibrant hues to match your exterior and interior aesthetics. The coloured profiles derive their colour through foiling (lamination) and co-extrusion techniques.

Popular Colour Options In uPVC Doors And Windows

Coloured uPVC is available in a wide variety of colour options to suit modern homes. They are mostly categorised into two categories: wooden grain finishes and solid colours.  Here, let’s see some of the popular colour options:

1. Wooden Grain Finishes

2. Solid Colours

Benefits Of Coloured uPVC Doors And Windows

Coloured uPVC windows and doors bridge the gap between architectural elegance and modern durability by offering key advantages. This section underscores some of the major benefits of foiled uPVC over standard white coloured doors and windows:

• Aesthetic Versatility: White uPVC may sometimes look like plastic, so many prefer to go with coloured profiles. They come in a wide range of finishes and colours, including woodgrains, so you can match or contrast your interior and outdoor designs.
• Low Maintenance: Unlike white, coloured profiles require very minimal upkeep because they hide dust, stains, and dark scuffs. Also, they do not need sanding, repainting, or varnishing.
• High Durability: Coloured windows and doors offer superior durability when compared to white because their factory-bonded acrylic foil acts as a protective shield. This foil reflects infrared rays, preventing warping.
• Customizable Design: Unlike white, colour profiles can enhance the curb appeal of a building and interiors. Colour customisation includes dual-tone, matte solids, and UV-resistant coatings.
• Environmentally Friendly: uPVC is highly recyclable due to its thermoplastic nature. The material can be melted and reshaped without losing its structural integrity. They are also 100 per cent lead-free because they are made of eco-friendly stabilisers like calcium and zinc.
• Enhanced Heat Shielding: The coloured foil blocks heat absorption at the surface level, working in tandem with a multi-chambered profile and fusion-welded joints. This maintains table indoor temperatures and reduces energy bills.
• Permanent Bonding: Low-quality white coloured uPVC can sometimes become yellow or discoloured. But coloured uPVC profiles feature a specialised foil finish applied during manufacturing, which permanently bonds to the frame. This avoids peeling, flaking, or fading when exposed to UV rays.

How Are Coloured uPVC Frames Manufactured?

The manufacturing of coloured uPVC frames is an advanced engineering process that takes place in several stages.

Here’s the step-by-step manufacturing process of coloured uPVC frames:

1. Extrusion

The manufacturing process starts with the blending of unplasticized Polyvinyl Chloride (uPVC) resin with modifiers, stabilisers, and base pigments. ASA or PMMA are used to improve UV protection.
The mixed resin is then heated abetween 200°C and 275°C. To create a shape, the molten mixture is run via a precision die trun through a precision die. It is then drawn through a vacuum calibration table and cooled in water baths. After cooling, they are subsequently cut into as per the required sizes.

2. Coloring and Lamination

Pre-extruded profiles are run through a wrapping machine to apply polyurethane hot-melt adhesives to add a rich colour or a woodgrain finish. Next, hot rollers are used to press and firmly wrap high-weather-resistant coloured foils around the uPVC core. They are then allowed to cure so that there is no internal stress and the glue permanently sets.

3. Quality & Finish

High-quality frames use special sun-blocking colors and sheets to stop profiles from bending, or fading in the sun. This lamination layer looks and feels just like real wood but doo not need painting or heavy cleaning. Strict factory inspections are performed on each frame to ensure they are strong and thick enough to block out loud noises and heavy rain.

4. Fabrication

Long galvanised steel bars are inserted into the profiles to offer strength and avoid deformation. The profiles are cut to exact window/door dimensions and welded at corners. Next, gaskets, security hardware, and glass panes are fitted into the frame.

Coloured uPVC vs White uPVC: Which Is Better?

Though both are made of the same material, they serve different priorities. Go through the table below to understand the differences:

Coloured uPVC vs Wooden Frames

Coloured uPVC frames are an excellent choice for contemporary homes due to their durability, little upkeep, and cost-effectiveness. Additionally, they are resistant to termites and rot.

On the other hand, wooden frames provide unmatched natural beauty, and classic elegance. However, they require regular, expensive maintenance (painting/polishing) to prevent weathering. Coloured uPVC is better for longevity, while wood is preferred for traditional aesthetics.

Factors to Consider Before Choosing Coloured uPVC Doors and Windows

This section highlights the importance of considering a the below factors to ensure structural longevity and over all return on investment.

• Colour Stability and Quality: Dark colours absorb more ultraviolet rays, which leads to fading, chalking, or yellowing over time. Ensure the profile utilises high-grade acrylic co-extrusion or premium foil lamination. Prefer a brand that offers warranty on colour and fading. A high–quality coloured uPVC profile must contain at least 2.5% titanium dioxide
• Heat Absorption Profile: Darker frames absorb more solar heat than white ones, risking profile warping or expansion in intense heat. Prefer verified tropical uPVC formulation with high UV stabilizers and multi-chambered profiles to avoid them. These act as thermal breaks to protect the frame’s shape and maintain stable temperature inside during summers.
• Design Match: Dual-colour flexibility allows you to have uPVC profile with two colours. For example, you can choose a dark colour like anthracite grey as the exterior shade and white or cream on interior finish. You can customise colour based on your interior needs.
• Quality and Durability: High-quality uPVC windows and doors features lead-free frames with a wall thickness of 2.2 to 3.0 mm. The internal galvanized steel reinforcement must be between 1.0 to 3.0 mm to prevent sagging and handle heavy glass. This structural integrity is important to hand handle harsh weather and maintain shape over time.
• Hardware and Security: A hardware is critical component of security and reliability. To prevent rust during monsoon, friction stays, handles, hinges and rollers must be made of marine-grade stainless steel to prevent rust and operational jamming. Prefer multi-point locking system to secure the frame at multiple place to make forced entry difficult.
• Maintenance: Coloured uPVC frames do not require repainting, sanding, or polishing. They demand only little upkeep. It only takes a quick wipe down with a soft cloth and mild soapy water to remove dirt. The hardware needs annual lubrication to keep mechanisms smooth and noise-free.
• Warranty and After-Sales Support: A comprehensive warranty helps against mechanical breakdown, peeling, and material failures. Reputable manufacturers provide a clear guarantee on hardware and profiles. Make sure the manufacturer has a dedicated after-sales support to address future issues.
