⚠️ Important Notice
Some suppliers cut costs by using thin glass in large rooflights — this can cause sagging and water pooling.
Our tests show that reinforced, thicker glass is essential for safety and durability.
At Saris-Extensions, every rooflight is built to UK standards, ensuring lasting strength and peace of mind.

Important Notes:
Over the years, we've observed numerous errors and poor practices in skylight installations that have led to persistent issues. To help you avoid these pitfalls, we're eager to share our accumulated expertise and knowledge. We highly recommend checking our detailed installation materials to ensure you apply the best practices for a flawless and durable installation.
When selecting sizes for our Skylights, please note that the listed dimensions correspond to the bottom (internal) glass panel. Each skylight's top panel extends an additional 100mm on each side, making the overall externally visible size 200mm larger in both width and length. This design ensures a robust, weather-resistant seal while maximizing the internal visibility and light entry of your skylight installation.
