Top Quality Materials

Our flush windows are made from uPVC, which is a highly popular material due to its incredible durability and longevity. There is a reason why so many homeowners choose uPVC for their windows. As soon as your flush windows are installed, you will be able to see the benefits almost instantly; due to the sleek uPVC profiles, sunlight can quickly spread across your home for a brighter and more luminous atmosphere. 

Starlight Windows use the highest quality materials to ensure that you get the most out of your investment; uPVC will stand the test of time whilst remaining in top condition. With its long lasting colour coating your windows can stay looking like when they were first installed. Our flush windows also come with trickle ventilation, which allows better airflow and harmful air to escape your home, which reduces the chances of condensation. You can also opt for concealed ventilation for a sleeker look; both help meet building regulations.

Energy Efficient Flush Casement Windows

Improve the energy efficiency of your home with our flush windows. Our flush windows come with a thermally efficient chambered outer frame for ultimate thermal comfort. We integrate double glazing within our windows for maximum energy efficiency; double glazing alongside our chambered outer frame helps to trap the warm air inside and keep the cold air out, so you can feel warm and cosy in the winter month and cool and ventilated in the summer months. You will become less reliant on your central heating, meaning you will save money on your energy bills, making our flush windows an excellent investment. 

No matter what the weather, our flush window will protect you against all weather conditions due to its high energy efficiency and weatherproofing strengths. As uPVC is highly durable, it can withstand strong forces and harsh weather conditions for a comfortable living space.
