Why choose our windows?
Popular Types Of Uk Windows
Sash Windows
Traditionally, sash windows were made from timber, soft and hardwoods, they are now made from various materials like virgin uPVC. This means that they can be just as energy efficient and safe as other types of windows. Box sash windows also come in many different styles.
Sash windows open and close via a sliding motion. This involves two sash panels vertically or horizontally sliding to create an opening. You can choose a sash window that only has a bottom or top sliding panel, or more traditionally, one that enables both sash panels to slide.
Casement Windows
Casement windows open by a hinge and they usually open and close just like a door. Casement windows are fairly energy efficient due to their virtually airtight lock and compression seal. Casement windows were popular in Victorian & Edwardian times and are still used a lot in newly built homes.
You can get casement windows in various different materials such as timber and uPVC.

Overhaul & Draught Proofing
Overhauling & Draught proofing helps revive old windows so that they work as intended.
- Replace broken or damaged sash cords.
- Re-weight and balance your sash windows so that they run as intended.
- Draught seal your windows to stop leaks and improve efficiency.
In order to draught proof or draught seal, we will seal gaps that have formed around your window and frame. If your windows are not draught proofed this may lead to dust, dirt, cold air and noise entering your home. Draught proofing also helps with the smooth running of your sash windows. It also means savings on energy bills by keeping the hot air in, and the cold air out in the cold months.
