Why buy uPVC Bay or Bow windows

Add an impressive feature to your home with bay or bow uPVC windows. These traditional styles of window extend outwards from the exterior wall of the property, allowing you to gain some extra space to that particular room.

What is a Bay window?

A bay window is supported from beneath, normally by a wall of the same shape, giving you more space from floor to ceiling. The bay itself can be simply window frames joined together, or have solid pillars or columns of brick or block, depending on the weight it needs to support. A Bay window is angular and not curved at all. It has three sides and will normally project much further from the property than a bow.

A bow window has a flat wall beneath it, providing a large raised “window shelf” for plants etc. The curve of the bow window is created from a series of straight edged casement windows (with or without opening sections.) The more window sections, the smoother the curve.

We thrive to only produce high quality windows, and in order to do that we manufacture our bay and bow windows in house. The 28mm sealed units are fully tested and certified for energy efficiency ensuring the product you are purchasing is of a high quality and standard.
5-Chamber System
All our uPVC bay and bow windows feature a 5-chamber 70mm profile. Having a thick 70mm profile guarantees a strong, rigid framework for the 28mm glass unit to sit within. The internal chambers protect against heat loss and are resistant to all weather conditions. The 5-chamber 70mm thick system is known to be one of the simplest, and easiest systems to install and can be used to replace old timber framed windows.
Internally Beaded
All our uPVC bay or bow windows are internally beaded, providing you and your home with better security. With internal beading the windows can’t be removed from the outside, whereas external beading can, making it harder for any intruder attempting to get into your property.
Security & Safety
The multi-point locking system provides you with supreme security, making it difficult for any uninvited guests to intrude. Our locking system consists of Espagnolette mushroom-headed locks, which slide in different directions before sitting securely in the metal keeps, unlike a simple roller cam system.

Furthermore, we have added anti-jemmy riser blocks to the internal uPVC frame that sit in the opposite direction to the Espagnolette mushroom-headed locks. This prevents anyone outside of the property to lever the locks out of place and gain access to your property.

The mechanism on the window handles are push to open, which are safer in the event of a fire as it allows quick opening of the window. These door handles come with key locks, locking the Espagnolette locks in place. Having the key locks adds to the security, as it completely stops the windows from being opened, especially when leaving your home unattended for a longer period of time.
28mm double glazing
All our windows have 28mm seal units, which consist of two 4mm panes of glass with a 20mm air gap incorporating a warm edge spacer bar. Units as such are more thermally efficient than aluminum bars, because aluminium is an efficient conductor of hot and cold temperatures which can contribute to a sealed unit breakdown. With 28mm sealed units there is also the added soundproofing benefit, which is convenient for anyone that lives on a main road or busy street.

In order to comply with part ‘L’ of building regulations, the glass we use in our sealed units features Planibel A (LOW-E) glass. This glass has a thin metal coating, designed to reflect the heat back into the room whilst still allowing the sun’s heat to pass through.

The glazing we supply complies to BS EN1279-2. This means our sealed units have been independently tested for moisture absorption which can lead to sealed unit breakdowns such as steam or condensation build up inside the sealed unit.
100% New Plastic
All our uPVC windows use 100% new plastic, which hasn’t been used, consumed or processed or subjected to processing other than for the purpose of being used as a window profile. Using new formed plastic material, can absorb more of the sun's UV rays, preventing the uPVC from discolouring and holding its pure white finish for a longer period of time.
Glass Reinforced Plastic Canopy
Within the canopy of our box windows, we use glass reinforced plastic (GRP), which is a highly versatile material that is flexible, lightweight and super durable. GRP is highly resistant to corrosion, ultraviolet light, excessive temperatures, salt air and acidic chemicals, as well as any wear and tear, pressure or damage.
