Top 10 Reasons to Choose Guardian Roof Lantern
All Aluminium System – Inside & Out
Robust, lightweight and durable
The lantern is manufactured from high-quality aluminium that is both strong and lightweight. A factory-applied finish ensures long-term durability, weather resistance and colour stability.
Why it matters to installers:
- Easier handling and lifting on site
- Less structural load on the roof build-up
- Long-lasting finish for timeless durability
GUARD-Lock ‘click-fit’ rafter system for easy installation
The proprietary GUARD-Lock technology uses engineered click-fit rafters that lock together securely and watertight. This reduces the number of separate components and simplifies assembly on site.
Why it matters to installers:
- Faster, more intuitive installation
- Fewer loose parts to manage on site
- Reduced risk of installation errors
Minimalist ultra-thin 12mm ‘V’ profile for maximum daylight
The slimline rafter design maximises glass area while maintaining structural strength. Fewer bars mean cleaner sightlines and a more contemporary aesthetic.
Why it matters to installers:
- Easier to sell to design-conscious homeowners
- Creates a premium visual finish with minimal effort
- Differentiates your installations from competitors
Flush-fit interior finish
no ‘fly-catching shelf’
The internal detail is designed to be smooth, avoiding awkward internal ledges that collect dust or insects. Plasterers can plaster cleanly to a point for a seamless ceiling finish.
Why it matters to installers:
- Much neater internal finish for the homeowner
- Easier coordination with plasterers
- Fewer snagging issues and callbacks
Adaptable to 70mm or 100mm upstands
The lantern can be configured to sit on either a 70mm or 100mm upstand depending on project requirements. This makes it compatible with a wider range of roof builds.
Why it matters to installers:
- Greater flexibility across different flat roof systems
- Reduces the need for bespoke site adaptations
- Easier integration with both Guardian and non-Guardian roofs
Class-leading thermal performance
The lantern is thermally broken throughout, combined with high-performance double or triple glazing. GUARD-Lock, the glazing enclosure and top cap all contribute to superior thermal efficiency.
Why it matters to installers:
- Strong compliance story for building control
- Better comfort for homeowners year-round
- Powerful selling point against cheaper lanterns
Double or triple glazing options for sound reduction
Acoustic dampening glass is available in both double and triple glazed formats. This is particularly beneficial in urban or noisy locations.
Why it matters to installers:
- Adds value for homeowners in built-up areas
- Helps you upsell premium glazing options
- Creates a quieter, more comfortable living space
Strong, secure and robust construction
A unique glazing enclosure and immovable top cap create a highly secure system. Anti-tamper rafter screws and fewer joints further enhance strength and security.
Why it matters to installers:
- Reassures homeowners on safety and durability
- Lower risk of long-term issues or movement
- Positions you as a quality-focused installer
Fast installation
can be constructed in under 60 minutes
Thanks to GUARD-Lock technology and pre-engineered components, assembly is quick and efficient. The system is designed for speed without compromising quality.
Why it matters to installers:
- Reduced labour time on site
- More jobs completed per week
- Higher profitability per installation
Scalable sizes with only four bars up to 2.4m x 3m (and beyond)
The lantern is available in standard sizes but can be scaled to bespoke dimensions. Even larger lanterns maintain a clean aesthetic using a minimal number of rafters.
Why it matters to installers:
- Suitable for both small and large projects
- Fewer bars = simpler installs
- Consistent appearance across different sizes
