Bay Windows

Enjoy floods of natural light and panoramic views by installing or updating bay windows in your home. Bay windows are formed of three or more individual windows connected in an arc which creates space and offers a beautiful panoramic view. Adding a projection to the outer wall, bay windows allow for a cosy, light-filled space to sit and relax in.

From both the inside and outside of the house, bay windows give the building additional character, due in part to the extra panes. Bay windows by TP Improvements are made to measure so you can truly bring your vision to life. They can be crafted from uPVC, aluminium, or timber to fit with the style of any property.

Highlights Of Bay Windows

Full Of Character

Bay windows add a beautiful, character filled feature point to the home, as well as allowing in light and creating a feeling of spaciousness. Whether you prefer traditional or modern, Bay Windows are versatile and adaptable enough to fit well into any property – from historic houses to new builds.

Enhanced Ventilation

As Bay and Bow windows extend outward from your house, they offer enhanced ventilation as air is able to move in and out of your home at multiple angles.

Add Value

Bay Windows may also add value to your property – not only do they enhance the aesthetics of a building but they also create additional space and light.

Made To Measure

Our team will create the right window for your project, according to your preferences and needs. We’ll assess the project, then create and fit the perfect Bay or Bow window for your space.

Energy & Money Saving

Replacing your old single glazed windows with our A rated double and triple glazing could save you hundreds of pounds on your energy bills each year. You’ll be letting light in and simultaneously keeping cold and noise out. Alongside amazing insulation solutions, all our windows also offer a high level of security, so you don’t have to compromise on style to feel safe and relaxed.

Bay & Bow Windows

What is the difference between bay and bow windows? Traditional bay windows (often found in Victorian and Georgian homes) actually extend the footprint of the room, so that the window space is projected outwards. This can be furnished with a window seat which makes for a sunny reading nook, or can simply add extra space to the room. Typically, bay windows consist of three glass panels, with one central picture window, and two smaller units on either side which open to allow ventilation.

Bow Windows on the other hand are usually made up of at least four or five identical windows which curve round to create an arced bow shape. This means Bow Windows offer a larger internal window ledge area, rather than extending the floor space like a bay. Bow Windows might be the right option for you if you are looking to allow the maximum amount of sunlight into your home. They also work perfectly wrapped around the corner of a building, where their curved appearance offers panoramic views.
