Premium windows at affordable prices

Available Throughout Portsmouth & The Whole of Hampshire

Portsmouth Casement Windows

Casement windows are known for their outward opening operation. They are available in numerous configurations, crafted from high-quality materials and available thousands of colour choices to match your home.

The tight seal achieved by our casement windows guarantees exceptional weather resistance, contributing to your safety and security.

Portsmouth Flush Windows

Flush windows (often called ‘flush casement windows’) have a clean flat profile, for a pleasing traditional look. Our flush window systems are offered in a diverse range of colours and materials to meet your needs.

Available in top-hung, side-hung and heritage styles, our flush fit windows combine modern machining processes with the discerning eye of a craftsman.

Portsmouth Tilt & Turn Windows

Double glazed tilt and turn windows offer unique advantages compared to traditional casement styles. The dual action opening means the upper sash tilts inwards, or with a different handle position the whole window can open inwards from the side.

In ’tilt’ position you can gently circulate air while keeping the lower section securely closed. In ‘turn’ position, you can completely open the window.

Portsmouth Bay Windows

Bay windows and bow windows, despite their similar names, are distinct styles. Bay windows extend the floor space of your property, whereas bow windows are usually supported underneath by a ‘gallows bracket’ and don’t generally require planning permission.

These windows are sought-after in Portsmouth because they have the ability to expand living, dining and bedroom areas, flooding them with abundant natural light.

Portsmouth Sash Windows

Sash windows are a classic, timeless design that is often found in Georgian or Victorian style houses around Portsmouth.

Sash windows are divided into two panes – a fixed outer pane at the top and a lower inner pane that slides open vertically.

These impeccably finished double glazed windows offer a great level of adjustment to the ventilation in a property, whilst remaining flush to the walls in any position.

Portsmouth Heritage Windows

The term ‘heritage window’ is often associated with a number of features available within a double glazing range. The most common items that qualify a window as heritage are:

  • Victorian Styling
  • Wood Appearance
  • Mock Hinges
  • Bespoke Leadwork
  • Sash Vertical Opening
  • Flush Fit Frames
  • Georgian Split Bars
  • Sculptured Frames
  • Cast Iron Handles
  • Conservation Approved

TRIPLE GLAZING OPTIONS

Upgrade your Portsmouth Double Glazing to Triple Glazing!

Triple glazing involves three panes of glass with two insulating layers of Argon gas in between. These quality windows represent a remarkable advancement in the realm of energy-efficient building technologies, offering exceptional thermal performance.

Those three layers of glass offer superior properties to double glazed windows, at just a small extra cost.

There are Many Benefits to Triple Glazed Windows

The primary advantage of triple glazed windows lies in their superior insulation properties. The additional glass pane and gas layers significantly reduce heat transfer, minimising energy loss and enhancing the overall thermal efficiency of a Portsmouth home or building.

Brackenwood triple glazing also offers significant benefits when it comes to reducing condensation. The technology behind triple glazing prevents condensation build-up on windows, keeping the interior of your home drier and healthier
