Customers Often Ask

Here's some of the questions we often get asked about casement windows:

What are casement windows?
Casement windows are a type of window that is attached to its frame by one or more hinges at the side. They can also be hinged at the top or bottom, which allows them to open outward, providing excellent ventilation and unobstructed views. This makes them a popular choice for many homes.
What are the benefits of casement windows?
The benefits of casement windows include great energy efficiency, enhanced security, and a wide range of customisation options. They create a tight seal when closed, which minimises air leakage and helps to keep your home warmer in the winter and cooler in the summer. They're also equipped with strong locking mechanisms that make them more secure against break-ins. Plus, you can choose from a variety of materials and colours to match your home's style.
Are casement windows energy efficient?
Yes, casement windows are more energy efficient compared to some other types of windows. Their design allows for very tight seals around the edges when they are closed, which reduces drafts and heat loss. This makes them an excellent choice for saving on heating and cooling costs.
Do casement windows open in or out?
Casement windows open outward. This design allows for maximum air flow and full utilisation of the window opening, providing better ventilation compared to other window types that slide to open.
What is your service area?
Our service area includes: Suffolk (Bury St Edmunds, Haverhill, Ipswich, Sudbury, Felixstowe, Newmarket, Lowestoft etc.), Norfolk (Norwich, Thetford, King’s Lynn, Gorleston-on-Sea, Dereham, Great Yarmouth etc.), Cambridgeshire (St Ives, Cambridge, St Neots, Huntingdon, Peterborough, Ely, Wisbech, March etc.) and North Essex.
