Black Brown uPVC Window FAQs
Find answers to common questions about our black uPVC windows here.
Standard window sizes vary in height and width, depending on your specific frame style and property type. While many houses follow these typical dimensions, some properties require bespoke window frames to fit odd shapes or structural openings.
We determine the overall frame size by measuring all sides of your existing windows to the exact millimetre. Getting these measurements right is essential before choosing a style, ensuring your new window unit fits like a glove and functions correctly for years.
Beyond our black-brown windows, we offer a versatile range of coloured uPVC windows to suit any property’s design. Find the right colours to achieve your desired look:
- Anthracite Grey: Sophisticated, deep grey, giving modern homes an industrial look.
- Golden Oak: A warm honey finish ideal for heritage buildings and traditional design aesthetics.
