Modern installers face a familiar challenge: delivering roofs that are not only structurally sound but also quick and efficient to install. The WarmerBeam system from Warmer Roof is engineered precisely to meet this demand, offering a high-performance solution for both conservatory roof replacements and new-build extensions.
By moving away from traditional timber trusses or bulky steel, WarmerBeam provides a lighter, more efficient system that improves installation speed while delivering superior structural performance.
Structural Engineering & Spanning Capability
At the heart of the system is the I-Beam 300 timber I-joist, crafted from C24 timber with a 10mm particle board web. This combination delivers an exceptional strength-to-weight ratio.
- Unsupported Spans: Achieve external projections of up to 7 metres, including a 400mm overhang, without additional internal supports.
- Retrofit Compatibility: The lightweight I-beam construction allows seamless retrofitting onto existing conservatory frames, reducing structural load compared to traditional solid roof options.
- Precision Manufacturing: Every component is cut to millimetre precision using advanced software and machinery, with a 5-day turnaround to keep your projects on schedule.
- Flat Roof Integration: For projects requiring flat roof sections, the system works seamlessly with Warmer Roof’s Flat Roof System, providing a consistent performance standard across complex extensions.
Thermal Performance & Compliance
WarmerBeam is meticulously tested to exceed building regulations in England and Wales, addressing the common “hot-house” or “ice-box” issues often associated with older glazed units. This ensures a comfortable, year-round habitable space for homeowners.
- Insulation Profile: Each kit includes premium honeycomb insulation and PIR insulated plasterboard as standard.
- S1 Roof Lantern Integration: The Warmer Aluminium S1 Lantern integrates seamlessly with the roof system. Its slimline ridge and discreet external rafter top cappings provide a “more sky, less roof” appearance, avoiding the bulky look of competitor profiles.
- Weatherproofing: Every kit comes with a Firestone RubberCover EPDM membrane, a durable single-ply solution with a 50-year life expectancy that installs significantly faster than traditional felt or GRP options.
The Complete Site-Ready Kit
WarmerBeam is delivered as a comprehensive, site-ready kit designed for a “plug-and-play” installation experience. This approach reduces on-site waste and eliminates the need for sourcing additional components.
