Concealed windows are gaining popularity in energy-efficient and passive houses across Berkshire, Hampshire, Surrey, and the South East.
The innovative design of concealed windows offers a clean and minimalist look that integrates smoothly with building façades, creating an almost invisible frame that places focus entirely on the glass.
Its futuristic appearance is admired by homeowners, architects, and developers across Berkshire, Hampshire, Surrey, and the South East, who want a minimalist aesthetic without compromising on thermal or acoustic performance.
This blog article explores what concealed windows are, why they are becoming a sought-after choice, and key factors to consider before installation.
Unlike traditional windows, which have a visible frame both inside and outside, concealed windows hide much of the frame within the wall or structural opening.
Only the glass surface is prominently visible. This effect gives residential and commercial buildings a sleek, uninterrupted aesthetic, allowing natural light to flood interiors with minimal visual interruption.
There are several reasons for the rise in popularity of concealed double-glazed windows across Berkshire, Hampshire, Surrey, and the South East.
● Minimal Visual Impact: Concealed windows offer a clean, modern finish that fits well with contemporary and minimalist architecture. The absence of window frames allows the focus to be on the view and natural light.
● Improved Light Flow: With the frame largely hidden, more glass surface area is visible, allowing more daylight to enter living spaces, which can improve well-being and reduce electricity use.
● Seamless Indoor-Outdoor Transition: These windows can be paired with sliding or folding door systems to create a smooth transition between interiors and outdoor areas, ideal for gardens and patios.
● Energy Efficiency: The double or triple-glazed units maintain strong thermal insulation, helping to reduce heat loss and keep homes comfortable throughout the year.
● Noise Reduction: The triple or double glazing also limits external noise, making it suitable for homes in busy or urban areas.
Concealed windows require careful design and construction to obscure the frames while ensuring structural integrity. Materials and finishes are thoughtfully chosen to blend seamlessly with the building’s exterior and interior.
● Frame materials typically include aluminium, timber, and composite options, all selected for their strength and minimal thickness. Aluminium is particularly favoured for its slim profile and durability.
● Flush-Fit Finish: Frames are often recessed to sit flush with external walls or cladding, making them nearly invisible from the outside.
● Colour Options: Many manufacturers offer custom colours to match or complement the building materials, further blending the window frames with the surroundings.
Concealed windows are designed to be discreet while still meeting or exceeding the UK’s energy performance standards. Look for windows that offer:
● Low U-values: To ensure heat retention during colder months.
● High Window Energy Ratings (WER): Indicating overall energy efficiency.
● Proper Sealing: Preventing drafts and condensation that could affect comfort and durability.
Building regulations must be followed, including those relating to ventilation and fire safety. Using registered installers helps guarantee compliance.
Installing concealed windows is more complex than standard windows and requires expertise:
● Structural Integration: Frames are set into walls or structural openings, so proper support and waterproofing are critical.
● Precision: Accurate measurements and fitting are essential to maintain the seamless appearance and performance.
These windows suit a variety of projects, including:
● Modern new builds are aiming for a minimalist façade.
● Extensions and renovations seeking a sleek look.
● Properties looking to maximise natural light without compromising thermal performance.
However, they may not be suitable for every property, especially listed buildings or those in a conservation area where restrictions apply.
Concealed windows often cost more due to the complexity of design and installation. Factors influencing cost include:
● Frame material and finish.
● Size and number of windows.
● Installation complexity.
● Additional features like solar control or acoustic glass.
Despite the higher initial outlay, benefits in comfort, aesthetics, and potential energy savings can provide value over time.
