Discover ROCKWOOL Twin Roll, the ultimate solution for high-performance thermal insulation in roof and loft spaces. As a leading provider of insulation products at www.pipelagging.com, we proudly stock this pre-split stone wool insulation roll, designed to deliver exceptional energy efficiency, fire safety, and ease of installation for UK homeowners and builders. With its low thermal conductivity and Euroclass A1 fire rating, ROCKWOOL Twin Roll is the go-to choice for upgrading cold-pitched roofs, attics, and even suspended ceilings.

What is ROCKWOOL Twin Roll?

ROCKWOOL Twin Roll is a versatile, non-combustible insulation material manufactured from high-quality stone wool. This eco-friendly product is pre-split into two convenient 100mm thick layers within each pack, making it simple to achieve a total insulation depth of 200mm. The innovative design allows for straightforward installation: place one 100mm layer between the rafters and the second 100mm layer over the rafters. This ensures optimal thermal performance while complying with UK building regulations for energy efficiency and fire safety.

Ideal for both residential and commercial applications, Twin Roll can also serve as an overlay for ceiling tiles in suspended ceiling systems. Its unfaced construction provides flexibility for various building setups, and it's CE marked to EN 13162:2012+A1:2015, guaranteeing reliability and quality.

Key Benefits of ROCKWOOL Twin Roll Insulation

• Superior Thermal Efficiency: Boasting a declared thermal conductivity of 0.044 W/mK (tested to EN 12667), this loft insulation minimises heat loss, helping you lower energy bills and reduce your carbon footprint. It's perfect for maintaining comfortable temperatures in UK homes during harsh winters.
• Unmatched Fire Safety: Rated Euroclass A1 to BS EN 13501-1, ROCKWOOL Twin Roll is completely non-combustible, offering peace of mind against fire risks in roof voids and attic spaces.
• Moisture Resistance: With No Performance Determined (NPD) for both long-term and short-term water absorption (EN 12087 and EN 1609), it's suitable for dry environments like lofts, preventing damp issues that could compromise insulation effectiveness.
• Easy Installation: The pre-split format saves time and reduces waste, making it DIY-friendly for homeowners or efficient for professional installers. Follow the detailed Roll, Twinroll, and Rollbatt Installation Guide for best results.
• Durability and Sustainability: Made from natural stone wool, it's long-lasting, recyclable, and contributes to sustainable building practices in line with UK green standards.
