Fully Insulated Upstands by Rooflight Factory
Experience exceptional performance and precision engineering with the Rooflight Factory Fully Insulated Upstand. Designed to provide optimal thermal efficiency and airtightness, this high-quality upstand ensures lasting durability and reliable support for skylight installations across flat and low-pitched roofs.
Superior Construction and Materials
Each upstand is crafted from premium, precision-bonded OSB (Oriented Strand Board) to deliver outstanding strength, uniformity, and resilience. The inclusion of advanced XPS insulation enhances its thermal properties, maintaining a comfortable indoor environment and helping to reduce energy costs.
- OSB Core: Provides structural integrity and dimensional stability.
- XPS Insulation: Offers superior thermal performance for improved energy efficiency.
- Seamless Airtightness: Ensures a robust, weather-resistant seal to prevent leaks and drafts.
Optimised Thermal Performance
The Rooflight Factory upstand creates an effective thermal barrier that helps retain heat indoors and keeps cold air out. This results in improved energy efficiency and year-round comfort, making it an ideal choice for both new builds and renovation projects.
Reliable Weather Resistance
The precise design ensures that the gap between your skylight’s underside and the upstand’s top provides a secure seal against moisture and air infiltration. This eliminates concerns about leaks or drafts, maintaining your home’s comfort and protecting your interiors from the elements.
For skylights installed on flat or low-pitched roofs, the upstand raises the unit at least 150mm above the finished roof surface and introduces a gentle incline to prevent water accumulation. This thoughtful design enhances both performance and longevity, while offering a clear, uninterrupted view of the sky.
Quick and Effortless Installation
- Ease of Handling: Lightweight and stable OSB panels allow for smooth, straightforward installation.
- Consistency and Strength: Uniform manufacturing minimises splintering or cracking during assembly.
- Time and Cost Efficiency: Simple installation saves labour time and reduces overall project costs.
Important: Screws and pre-drilled mounting holes are not included in the package.
