When it comes to home renovation projects, replacing old, drafty windows with modern, energy-efficient sash windows can make a big impact on both the look of your home and your energy bills. Sash windows, with their traditional double-hung design allowing both the top and bottom panes to slide up and down, have been a popular choice for centuries thanks to their elegance, functionality, and natural ventilation.
Though wood sash windows have an undeniable charm, for many homeowners, uPVC (unplasticized polyvinyl chloride) is the best sash window replacement option.
uPVC combines the traditional look and feel of wood with superior insulation, weatherproofing, and durability. Read on for an in-depth look at the benefits of uPVC sash windows and a step-by-step guide to smoothly installing them as part of your next home renovation project.

Why Choose uPVC for Sash Window Replacements?
There are many reasons to select durable, low-maintenance uPVC over wood when replacing outdated sash windows:
Energy Efficiency and Cost Savings uPVC sash windows offer far better insulation than old single-pane wood windows. This keeps warm air in during the winter and hot air out during the summer, allowing you to maintain a comfortable temperature in your home with less energy usage. Over time, upgrading to uPVC sash windows can add up to huge savings on energy bills.
Strength and Security Reinforced with galvanized steel, uPVC frames are highly impact-resistant and difficult to force open, acting as a deterrent to would-be intruders. Compared to rot-prone wood, they also maintain their strength and shape over time, meaning no cracked panes or windows stuck shut.
Weather Resistance uPVC’s dense, nonporous surface repels rain, sleet, and snow. Unaffected by moisture, it won’t swell, crack or warp like natural wood. This allows uPVC sash windows to retain a like-new appearance and smooth operation through years of use.
Low Maintenance A simple wipe down is all that’s needed to keep uPVC frames looking fresh. No time-consuming sanding, painting, or staining required! The color goes all the way through the material as well, so scratches are less noticeable. uPVC is also resistant to rot, termites, and other wood-damaging pests.
Design Flexibility uPVC sash windows are available in virtually any color or finish you desire – from classic white to woodgrain effects. Customizable accessories like molded sill covers, concealed hinges and Georgian bars allow you to match existing architectural details or create an entirely new look.
Step-by-Step Guide to Replacing Wood Sash Windows with uPVC
Now that you’ve weighed the benefits, follow this step-by-step process for a smooth sash window replacement:
- Select a contractor. A window specialist, rather than a general contractor or carpenter, is best equipped to properly remove and install sash windows. Ask friends and neighbors for referrals or search online reviews.
- Choose new sashes. Pick out replacement uPVC sashes that match the size of your existing wood sash windows as closely as possible to minimize construction work needed. Custom-sized units are also an option. Consider accessories like security locks.
- Prepare the rough openings. Have existing sashes and frames fully removed, taking care to protect interior walls and trim work. The contractor will inspect and repair any damage to the rough window openings in preparation for the new uPVC sashes.
- Install flashing and seal perimeter gaps. Before inserting the new uPVC sashes, the contractor will waterproof and air seal the openings, adding flashing material around the perimeter as needed. This is crucial for energy efficiency as well as weather and pest resistance.
- Put in the new sash windows. With openings prepped, it’s time for the new, factory-finished uPVC sash window units to be put into place. The contractor will ensure they are perfectly plumb and level for ideal operation and appearance. All hardware should also be properly adjusted.
- Caulk and trim. For maximum weatherproofing and an integrated look with the surrounding wall surface, the contractor will thoroughly caulk around the newly installed window units. Interior stops/trim and exterior moldings will also be added to neatly finish off the replacement job.
- Make final adjustments and clean the glass. Before the big reveal, the contractor will test that both upper and lower sashes slide smoothly when locking, unlocking, and raising/lowering. Lastly, the glass and uPVC surfaces are wiped down, leaving your home’s new focal point sparkling clean.
