Introduction
Traditionally, chimneys are constructed on site with separate components supplied by different manufacturers. This process is labour intensive and makes it difficult to ensure consistent insulation. By contrast the Lagan Chimney System offers modular, prefabricated units to speed construction and facilitate consistent quality standards.
Product Description
The Lagan Chimney System is a prefabricated, insulated chimney system for use in domestic accomodation. The chimney systems are available in 11 options as detailed throughout the website.

The concept involves a modular 3-layer insulated chimney system:
1st Layer
A high quality rebated flue liner, made of fireclay, tested to EN1457.
2nd Layer
A flexible rockwool insulation of density 90kgs/m2 designed to maintain the temperature of the flue gases and allow them to pass freely up the chimney. It also allows the liner to expand and contract without damage.
3rd Layer
A lightweight aggregate chimney block which safely encases the entire system and provides additional insulation.

General Uses
• Designed for speed of construction
An 8 meter internal chimney can be constructed from ground floor to chimney pot in 5 hours.
• Suitable for Timber Frame, Steel Frame, ICF (Insulated Concrete Formwork) & Masonry construction
Solutions have been specifically designed to meet the requirement of timber framed construction.
• Modular units for easy assembly on site
• Multi Fuel Compatible
Suitable for all fuels - gas, oil, wood and solid fuels.
• Everything you need
All the components required to construct the chimney from the ground floor to the chimney pot are supplied on one or two pallets.
• Superior Insulation
The consistency of the insulation maintains the temperature of the flue gases allowing them to pass freely up the chimney. Back filling of insulation is not required.
The Lagan Chimney System Concept
The Lagan Chimney System is designed to offer fast and efficient erection on site and is suitable for all types of domestic heat appliances. They can accomodate both open fire and closed appliances using fuels with an output of up to 45 kilowatts. The system is delivered to site in component form on pallets and contains all the material neccessary to construct a chimney from the base to chimney pot.
The Lagan Chimney System is ideal for Open Fires, Stoves, Cookers and Central Heating Boilers.
Lagan Chimney Systems is part of the Lagan Group. In keeping with the standards expected from such a prestigious pedigree, the group is certified to EN ISO 9001.
The Lagan Chimney System Overview
All the materials needed to construct the chimney from the base to the chimney pot are supplied as part of a pack. This includes blocks for the chimney breast. The pack for a standard 8 metre chimney can be fitted on two pallets.
All the blocks are supplied as part of the pack and are lightweight and made to fit together. Unlike standard blocks, Lagan Chimney Systems chimney blocks have high insulation properties.
The high quality fireclay flue liner complies with the European Standard EN1457.
An expansion plate allows for vertical expansion and the insulation in the system permits horizontal expansion. A high temperature ceramic sealant is provided in tubes for ease of application.
The consistency of the insulation properties helps maintain the temperature of the flue gases, allowing them to pass freely up the chimney. The higher spec insulation incorporated with the insulating qualities of the aggregate in the flue block help achieve and maintain a higher temperature within the flue liner than a traditional style chimney (back filled with a weak mix of sand, lime and cement). This helps to reduce problems associated with traditional chimneys, i.e. lack of draught.
Suitable for timber frame, steel frame, ICF (Insulated Concrete Formwork) and traditional masonry construction.
The Benefits
• Speed
The chimney system is designed in modular units which can be quickly assembled on site, significantly reducing the chimney construction time. The complete system for a standard chimney is supplied on two pallets, ready to be built.
• Safety
The high temperature sealant offers greater protection against leaks. The higher insulation properties of the 3-layer system minimises condensation, reducing the likelihood of chimney fires and moisture staining on the chimney breast.
• Consistency
The prefabricated nature of the Lagan Chimney System increases the consistency of the product thereby reducing the exposure to error.
• Multi Fuel
Lagan Chimney Systems is suitable for all fuels - gas, oil and solid fuel.
Certification
The Lagan Chimney System has been approved and certified by the Irish Agrément Board and issued with the following certificate number: 01/0129. Full certification can be reviewed on the Irish Agrément Board Website - www.irishagrementboard.com
