Choosing between sliding sash and casement windows
If you are planning new windows for your home, deciding between sliding sash vs casement windows is often one of the first big questions. Both styles have their own character, their own practical benefits and their own place in different types of property. Getting the choice right matters, especially with timber windows that are built to last for decades.
At Hinson Custom Made, we design and craft bespoke timber windows for homes across Buckinghamshire and beyond. We make both flush casement and sliding sash windows, so we see first-hand how each style suits different homes and different priorities. Here is what sets them apart.
What is a casement window?
A casement window is hinged at the side and opens outward, much like a door. They are simple, practical and tend to suit a wide range of property styles, from cottages to contemporary new builds.
Benefits of casement windows include:
- Wide, unobstructed opening for maximum airflow
- Strong seal when closed, which helps with draught reduction
- Straightforward operation, often with a single handle
- A clean, classic look that suits both traditional and modern homes
Because the whole window swings open, casements are particularly good for rooms where ventilation matters, such as kitchens and bathrooms.
What is a sliding sash window?
Sliding sash windows are the classic choice for period properties. Rather than hinging outward, the panes slide vertically past each other within the frame. This style is closely associated with Georgian and Victorian homes, where it remains one of the most authentic ways to restore or replace original windows.
Benefits of sliding sash windows include:
- Authentic period appearance, ideal for listed buildings and conservation areas
- No outward swing, so they do not interfere with curtains, blinds or outdoor space
- Adjustable ventilation, since the upper and lower sashes can be opened independently
- A timeless look that adds character and often adds value to a property
We have worked on sliding sash projects in listed buildings, including a recent installation of three first floor windows in Earl’s Barton, where matching the original style was essential.
Performance and security
Whichever style you choose, performance should not be a compromise. Hinson timber windows are tested to comply with UK Building Regulations and certified to PAS 24:2016 for security and BS 6375:2015 for weather tightness. This means both casement and sliding sash options are built to perform well against the British weather while keeping your home secure.
We also offer windows crafted from Class 1 grade Accoya timber, which carries a guaranteed service life of up to 50 years. Its acetylation process makes it highly stable and suitable for both painted and natural finishes, so you are not limited on colour or grain choice regardless of which window style you prefer.
Which style suits your home?
There is no single right answer. The best choice depends on your property and what matters most to you.
Casement windows tend to suit:
- Modern or contemporary properties
- Homes where maximum ventilation is a priority
- Budget conscious projects, as casements are often simpler to manufacture
Sliding sash windows tend to suit:
- Period and listed properties
- Conservation areas with strict planning requirements
- Homeowners prioritising authenticity and character
If your home sits within a conservation area or is a listed building, sliding sash is often the more appropriate choice for planning purposes. For everything else, the decision usually comes down to personal taste and how you want the windows to function on a day-to-day basis.
Sustainability and craftsmanship
Whichever style you go for, the timber itself matters. All timber sourced and used by Hinson Custom Made comes from a replenished source, with purchased timber coming from suppliers holding FSC, PEFC or CPET membership. This means your new windows are not just beautifully made, they are sourced responsibly too.
Every window is handcrafted to order, with full attention given to glazing, ironmongery and finish. Before work begins, a member of our team will sit down with you to talk through your requirements, so the final result fits your home exactly as planned.
