When it comes to ensuring the longevity and safety of your chimney flue system, choosing the right accessories is paramount. The Wall Sleeve Ø 150mm from National Flues is designed to secure the transition of your flue through external walls and protect it from external elements. This comprehensive guide will walk you through everything you need to know about this essential accessory, addressing common questions and outlining why it is the ideal choice for your flue installation.
Understanding the Importance of a Wall Sleeve
A wall sleeve plays a critical role in maintaining the integrity of your chimney by providing a protective barrier where the flue passes through the wall. Key aspects include:
- Protecting the flue from the harsh external environment.
- Maintaining the required distances from combustible materials, thus enhancing safety.
- Ensuring that the installation meets regulatory standards such as those established by HETAS and CE.
The Wall Sleeve Ø 150mm is specifically designed to adhere to these requirements, making it suitable for a wide range of heating appliances including woodstoves, gas boilers, and oil-fired systems.
Material Quality and Design Benefits
This product boasts an outer skin made of 304-grade stainless steel and an inner skin of 316L stainless steel, each with a thickness of 0.40mm. Such high-quality materials offer unparalleled resistance to corrosion and thermal stress. Additionally, the insulation is provided by compressed rockwool, available in densities optimised for TWPro and KC systems.
Why Material Quality Matters:
- Durability: The robust construction significantly extends the lifespan of the wall sleeve, ensuring it remains reliable over many years.
- Thermal Performance: The compression rockwool insulation helps maintain thermal efficiency, keeping heat contained within the flue system.
- Safety: Compliant with strict HETAS and CE standards, this product minimizes the risk of fire hazards by maintaining the required distance from combustibles.
Installation Made Easy
Installing the Wall Sleeve Ø 150mm is straightforward, even for those with limited experience. The process involves securing the sleeve in place using a Locking Band, which keeps all components firmly fitted. If the installation requires the sleeve to be positioned at an angle (commonly at 45 degrees), it is necessary to taper-cut the product. This can be accomplished using a grinder or hacksaw, making it easy to achieve a neat and flush installation.
Installation Tips:
- Ensure all measurements are accurate to maintain the specified combustible distances (50mm for TWPro and 60mm for KC).
- Use proper tools when performing a taper-cut to avoid damaging the sleeve or compromising its integrity.
- Always double-check local building regulations to confirm that your installation meets all safety and clearance standards.
Addressing Common Objections
