Flatglass Skylights

Opting for a framed unit guarantees a much simpler installation process, greater structural integrity, and highly reliable long-term performance. The aluminium framework fully supports the glass and covers its weakest points. This design dramatically lowers the chances of accidental site damage, sealant breakdown, and future water ingress, giving you a far safer and more dependable product.

We provide kerbside delivery for all of our skylights. Once your order has been placed, you will be notified of your scheduled delivery date. At this stage, we will also advise how many people are recommended to be onsite to safely receive the delivery, based on the weight and size of your order.

Low-E soft coat glass is an advanced type of energy-efficient glazing technology specifically designed for modern skylights and windows. "Low-E" stands for "low emissivity," referring to the microscopically thin, transparent metallic coating applied to the glass surface that selectively reflects thermal radiation (heat) while allowing visible light to pass through.

This specialised coating works by reflecting infrared heat back to its source, effectively keeping your home warm during winter months by preventing indoor heat from escaping through the skylight, and cool during summer by reflecting solar heat away from your living space. The soft coat variant is particularly effective, offering superior thermal insulation properties compared to traditional glazing options.

By installing skylights with Low-E soft coat glass, homeowners can significantly improve their home's thermal envelope, reduce energy consumption for heating and cooling, lower utility bills, and create a more comfortable living environment year-round. The technology also helps minimise harmful UV radiation that can fade furnishings and flooring, providing additional protection for your interior spaces.

An Argon-filled cavity is a premium insulation feature found in high-quality skylights and windows. Argon is a naturally occurring, colourless, odourless, non-toxic noble gas that is heavier than air and has superior insulating properties. In double or triple-glazed skylights, the space between glass panes is filled with Argon gas instead of regular air.

Argon gas delivers exceptional thermal performance because it has significantly lower thermal conductivity compared to standard air, meaning it drastically reduces heat transfer through the skylight. This creates a more effective thermal barrier that keeps interior heat inside during colder months and prevents external heat from entering during warmer seasons.

Beyond temperature regulation, Argon-filled skylights provide additional benefits, including improved sound insulation, reduced potential for internal condensation, and enhanced energy efficiency. These performance advantages translate to more consistent indoor comfort, lower energy bills, and reduced environmental impact through decreased energy consumption for heating and cooling. The Argon gas is securely sealed within the glass unit and maintains its insulating properties for many years, contributing to the long-term performance of your skylight.

U-value, or thermal transmittance, is a crucial measurement that quantifies how effectively a building element prevents heat from escaping or entering a structure. Measured in Watts per square meter Kelvin (W/m²K), this standardised value is particularly important when evaluating the thermal performance of skylights and roof windows.

The U-value specifically indicates the rate of heat transfer through a building component – in this case, a Skyseal skylight. The lower the U-value, the better the thermal insulation properties and the more energy-efficient the skylight will be. This translates directly to improved temperature regulation in your home and potential savings on heating and cooling costs.

The current UK Building Regulations establish specific U-value requirements for various building elements to ensure compliance with energy efficiency standards. For skylights and roof windows, existing dwellings must achieve a maximum U-value of 2.2 W/m²K, while new construction projects typically require more stringent values between 1.2 and 1.7 W/m²K, depending on the specific application.

Our premium skylight range exceeds these regulatory requirements, with models featuring advanced glazing technologies that deliver exceptional U-values as low as 0.9 W/m²K in some configurations. This superior thermal performance contributes to reduced energy consumption, a smaller carbon footprint, and enhanced comfort through consistent interior temperatures regardless of external weather conditions.
