Description
Redstone Pura Core board is a high–performing mineral-based insulation board that helps maintain and optimise a building’s ability to breath while helping to reduce the risk of condensation and mould. It provides an A1 fire-rated, sympathetic and moisture-safe means to prevent heat loss through the solid outer walls of buildings, Redstone Pura Core is ideal for enhancing an old building’s breathable quality or newer buildings which suffer from condensation or mould issues, and provides a sympathetic means of preventing excess heat loss through the outer walls. Redstone Pura Core can be used to insulate the walls while respecting the needs of older buildings.
Where to use it
Redstone Pura Core mineral insulation board, designed to manage moisture, is used on solid stone or solid masonry walls and window reveals. It can also be used on solid concrete walls and ceilings (of any thickness), and in taller buildings or apartment blocks where a non-combustible internal wall insulation is required. It is also suitable for use in waterproofed basements where a cement-based tanking system without a membrane was used.
What it does
Redstone Pura Core helps alleviate condensation and mould issues that can negatively impact indoor air quality and potentially cause structural damage.
By combining effective thermal insulation with moisture and humidity control, it significantly improves internal comfort and indoor climate conditions. A 60mm application of Redstone Pura Core insulation system on a traditional 600mm stone wall with internal lime plaster can reduce heat loss through conduction by up to approximately 430%, dramatically improving energy efficiency.
Its ability to regulate humidity makes it particularly suitable for buildings with highly variable moisture levels, such as museums, churches and schools, where frequent occupancy changes can cause fluctuations in humidity. It also helps protect sensitive contents within buildings, including paintings, furniture, musical instruments, MDF products and various fabrics that may be vulnerable to moisture changes.
Features
- Capillary Active and Breathable
- Made from lime and sand
- Natural mould inhibitor
- Ideal internal insulator for Listed or historic buildings
- Ideal internal insulator for commercial and domestic refurbishments
- Excellent natural thermal insulation
- Non-combustible (A1 Fire rating)
- Lightweight, easy to cut, shape and install
Benefits
- Hydrophilic properties ensures optimal moisture regulation in older buildings
- With a value of between µ-value 3-7, it allows water to actively move through the wall and rapidly evaporate helping it to dry out faster and more easily.
- Having a high alkaline pH value, the board inhibits mould growth
- Euro fire classification A1 non-combustible product. Easy to comply with Part B Fire safety requirements of the building regulations
- The low-emission manufacturing process for Redstone Pura Core boards made solely from natural raw materials results in less environmental impact
