Pro’s and Con’s to Aluminium windows:

Before making a decision on whether aluminium windows and doors are the right choice for your home, it’s important to weigh the advantages and disadvantages of this popular fenestration option.


  1. Durability: Aluminium is inherently resistant to rust, corrosion, and weather damage, making it an ideal choice for exterior applications. Aluminium windows and doors can withstand exposure to harsh environmental conditions, including rain, wind, and UV rays, without deteriorating over time.
  2. Sleek Design: Aluminium frames boast slim profiles, allowing for larger glass areas and maximizing natural light ingress. The sleek and modern aesthetic of aluminium fenestration complements various architectural styles, from contemporary to industrial, adding a touch of sophistication to any space.
  3. Energy Efficiency: With advancements in thermal break technology, aluminium windows and doors offer excellent insulation properties, helping to minimize heat transfer and reduce energy consumption. Properly insulated aluminium fenestration can contribute to a more comfortable indoor environment and lower heating and cooling costs.
  4. Low Maintenance: Aluminium requires minimal upkeep compared to other materials such as wood or uPVC. Regular cleaning and occasional lubrication of hinges and tracks are typically all that’s needed to keep aluminium windows and doors looking and performing their best.


  1. Thermal Conductivity: Aluminium is a highly conductive material, meaning it readily transfers heat and cold. Without proper thermal insulation, aluminium windows and doors can contribute to heat loss in winter and heat gain in summer, potentially leading to energy inefficiency and increased heating and cooling costs.
  2. Condensation: In colder climates, aluminium frames can be prone to condensation buildup, particularly if they are not adequately insulated. Condensation on windows and doors can lead to moisture-related issues such as mold growth, rot, and damage to surrounding surfaces if not addressed promptly.
  3. Cost: Aluminium windows and doors tend to have a higher initial cost compared to other materials such as uPVC or timber. While the durability and longevity of aluminium fenestration can offset this initial investment over time, the upfront cost may be a consideration for budget-conscious homeowners.
  4. Limited Colour Options: While aluminium frames can be powder-coated in a wide range of colours and finishes, the customization options may be more limited compared to other materials such as uPVC or timber, which can be painted or stained to match specific design preferences.

Overall, aluminium windows and doors offer numerous benefits, including durability, sleek design, energy efficiency, and low maintenance requirements. However, it’s essential to consider potential drawbacks such as thermal conductivity, condensation, initial cost, and limited colour options when making a decision for your home.

Maintenance Tips:

To ensure your aluminium windows and doors remain in optimal condition and continue to enhance your home’s aesthetics and functionality, it’s essential to follow these maintenance tips:

  1. Regular Cleaning: Keep your aluminium frames and glass surfaces clean by wiping them down regularly with a mild detergent and water solution. This helps remove dirt, grime, and debris that can accumulate over time and detract from their appearance.
  2. Lubrication: Apply a silicone-based lubricant to the hinges, tracks, and locking mechanisms of your aluminium windows and doors. This helps to ensure smooth operation and prevents friction-related issues that can arise over time. Regular lubrication also helps to protect against corrosion, particularly in areas prone to high humidity or salt exposure.
  3. Inspect Seals: Check the weatherstripping and seals around your aluminium windows and doors on a regular basis. Look for signs of wear, tear, or damage, such as cracking, peeling, or gaps. Damaged seals can compromise the energy efficiency and weatherproofing of your windows and doors, leading to drafts, moisture infiltration, and increased energy bills. Replace any damaged seals promptly to maintain optimal performance and prolong the lifespan of your aluminium fenestration.

By incorporating these maintenance practices into your regular home care routine, you can ensure that your aluminium windows and doors not only look their best but also continue to provide reliable performance and protection for years to come.
