When planning a home extension, renovation, or a new build, few things transform a space quite like natural light. It elevates our mood, makes spaces feel larger, and completely changes the aesthetic of a room. However, adding expansive glass shouldn’t mean sacrificing your home’s thermal comfort.
If you are looking for the ultimate balance of sleek architecture and industry-leading insulation, the Custom Rooflights Triple Glazed Flat Rooflight is the perfect solution.
The best part? While they feature a sleek, modern “flat” profile, these high-performance skylights are incredibly versatile and designed to perform brilliantly on both flat roofs and pitched roofs.
Here is everything you need to know about integrating them into your next project.
The Versatility Factor: One Rooflight, Two Roof Types
A common misconception is that a “flat rooflight” can only be installed on a flat roof. In reality, the term refers to the flush, minimalist style of the glass panel itself—not its limitations.
1. Seamless Integration on Flat Roofs
On contemporary flat roof extensions (such as modern kitchens or living areas), these rooflights sit beautifully to create a flush, frameless aesthetic. When installing on a flat roof, a minor pitch (typically a minimum of 5 degrees) is used via the builder’s kerb to allow rainwater to run off effortlessly, keeping your glass crystal clear.
2. A Sleek Alternative for Pitched Roofs
If your property has a pitched or sloped roof, installing a flat-profile triple-glazed rooflight offers an ultra-modern alternative to traditional, bulky roof windows. It sits closely to the roofline, providing a clean, architectural finish that floods the room below with uninterrupted vertical light.
Key Benefits of Custom Rooflights‘ Triple Glazed System
Choosing triple glazing over standard double glazing is one of the smartest investments you can make for your property. Here is what sets the Custom Rooflights system apart:
Ultra-Low 0.6 W/m²K U-Value for Superior Energy Efficiency
Energy efficiency is more critical than ever. Our triple-glazed units feature an exceptional system U-value of just 0.6 W/m²K, achieved using two layers of advanced Low-E glass and argon gas insulation. This means virtually zero unnecessary heat loss, keeping your home warm in the winter and comfortably cool during the summer.
Maximum Security and Peace of Mind
Safety should never be a compromise. These rooflights feature three robust layers of protection: a 6mm toughened safety top pane paired with 4mm middle and bottom toughened safety glass layers. Built to conform to BS EN 12150 standards, they easily withstand harsh UK weather and provide optimal security.
Self-Cleaning Glass Technology
Nobody wants to spend their weekends climbing ladders to clean roof windows. The outer pane is equipped with specialized self-cleaning glass that uses UV rays from the sun to break down organic dirt, which then washes away cleanly when it rains.
Advanced Acoustic Insulation
An underrated benefit of triple glazing is sound reduction. If you live in a busy urban area, near a main road, or simply dislike the sound of heavy rain drumming on the glass, the three-layer composition acts as an excellent acoustic barrier, keeping your interior peaceful and quiet.
Sleek, Frameless Aesthetics
Designed with a modern, frameless aesthetic, these skylights maximize the visual glass area. By minimizing visible internal frames, you get an unobstructed view of the sky, letting in the maximum amount of natural daylight while allowing complete flexibility for your internal plasterboard finish.
Pro Installation Tip: When fitting your triple-glazed flat rooflight, we highly recommend using a premium, high-movement, low-modulus glazing silicone (such as DOW791) to guarantee longevity and weather-tight performance.
