Flush casement windows are a superb renovation choice for homeowners in Newbury and Berkshire, featuring a sleek, fully flush design that complements both modern and traditional properties. Particularly favored by owners of period homes, these windows serve as excellent timber replacements, crafted with authentic joinery and available with woodgrain foil for a realistic hardwood look.
Made from uPVC, flush casements offer numerous benefits, including complete thermal efficiency, easy installation, weatherproofing, and enhanced security. They are fully customizable to match your home’s décor perfectly. Additionally, these windows retain all the configuration options of conventional casements, allowing for various panel styles, fixed frames, larger profiles, and choices between top or side hung mechanisms. This versatility ensures that flush casement windows can meet almost any requirement within your home.
With older timber profiles, one common issue is problems with weatherproofing. As wood becomes older, water ingress becomes more common, due to the permeability of the older timber. This isn’t a problem with our flush casement windows.
Visually, they can authentically replicate timber windows, despite being made from uPVC. By doing this, you’ll maintain your home’s period charm, while also protecting it against the elements. You’ll never have to worry about problems such as rotting, damp or mould.
uPVC is a fantastic insulator. As a result, our flush casement windows achieve fantastic standards of thermal retention. Internal chambers within the profile work in harmony with the double glazing to ensure that your home’s natural warmth is trapped within the home during winter.
Older properties have a reputation for subpar thermal efficiency. Renovate with Castle Windows, and you can ensure that your home remains at the optimal temperature all year round. All the while, our flush casement windows ensure that you maintain any traditional aesthetics.
Our flush casement windows are both low maintenance and long lasting. uPVC is famed for its ability to last for decades, even when subjected to extreme weather conditions. Our flush casement windows will never bow or warp within the profile.
What’s more, you are only required to complete occasional maintenance, whereas authentic timber requires much more regular upkeep. The coloured foil will never need refinishing, while you’ll only need to ensure that the moving components are free of excess dust or any debris.
