Roto Pitched Roof Skylight Center-Pivot 74 x 140 cm PVC
Pivot Skylights with Built-in Thermal Insulation (WD Block)
The WD Block system enhances the thermal efficiency of skylights, especially at critical junctions with the rafter framing. Here’s how it elevates your living space:
Enhanced Insulation
The WD Block system fortifies the entire perimeter and height of the frame, targeting the areas most susceptible to heat loss and moisture. This ensures a warmer and drier environment, improving your comfort.
Energy Savings
With the WD Block, our skylights significantly minimize energy leakage during colder months, which can lead to considerable savings on heating costs.
Improved Energy Balance
Integrating the WD Block leads to a 15% improvement in the skylight’s energy balance, enhancing thermal efficiency across the board.
Increased Temperature at Critical Points
This system increases the temperature by approximately 5ยฐC at the crucial interface between the skylight frame and its niche, reducing the risk of condensation and boosting overall comfort.
Seamless Integration
The WD Block ensures a tight and energy-efficient connection between the skylight and the roof, enhancing both the aesthetic and functional qualities of your home.
Product Quality
Roto Designo PVC skylights stand out for their exceptional durability and safety, attaining the highest fifth security grade which provides robust protection against external impacts. These skylights are not only eco-friendly due to their lead-free composition but also feature:
- UV resistance to protect interiors from sun damage.
- Superior durability and low maintenance requirements, maintaining a pristine appearance for years.
- Ideal suitability for moisture-prone areas like kitchens and bathrooms, and excellent performance in coastal regions due to their corrosion-resistant properties.
Glass Structure
- Exterior: Toughened safety glass with hail protection.
- Interior: Standard float glass.
Functionality
Center-pivot skylights offer manual operation for reliability and ease of use. Designed for convenience, these skylights support straightforward cleaning and maintenance, enhancing the comfort and hygiene of your home. They allow for the integration of various accessories and can be paired with other models to increase natural light and ventilation.
Energy Efficiency
Achieve exceptional energy savings with skylights that boast a Uw rating of 1.3 due to their advanced thermal insulation (WD Block). This feature not only enhances the energy performance of the skylights but also contributes to a more sustainable living environment by reducing energy consumption.
Quick and Reliable Installation
Enjoy a swift and secure installation process with our skylights. Features like pre-installed assembly brackets and integrated roof coverings streamline the setup, ensuring a smooth and efficient installation. Each skylight comes equipped with pre-installed thermal insulation (WD Block) and a vapor barrier film, which provide an airtight seal, perfect alignment, and consistent positioning from the start.
Design
Our skylights combine form and function seamlessly. With no visible screws, each unit presents a clean, polished look. The modern design adds a contemporary edge to any architectural style, and the attractive anthracite-metallic color of the coverings offers a sophisticated touch that complements various exterior designs.
PVC Structure
Unlike many other PVC skylights in the market, Roto Designo models are crafted from solid 100% PVC, ensuring unmatched durability. The multi-chamber profiles of our skylights provide exceptional energy and acoustic insulation, enhancing both energy savings and living comfort.
