Ceramic Eldfast lining - HETAS approved system

Click here to see our Eldfast lining animation that we had commissioned.
 
We at The Cast Iron Fireplace Company are approved installers of the Eldfast Ceramic Lining system. It is recognised by HETAS as an approved form of chimney lining. 

We cover London and the South of England for Eldfast installations and chimney CCTV inspections, click here to see our installation areas we cover map.
  
We are proud to be approved Eldfast contractors and our Eldfast fitters are highly skilled chimney engineers. It takes time and experience before becoming an approved installer of the Eldfast system.

ELDFAST: The chimney lining that lives up to its name and suitable for lining chimneys in thatched properties.
 
•   Lines the leaking flues without removing the fireplace
•   Suitable for all fuels
•   Suitable for stoves and open fires
•   Unique applications to smaller flue voids, e.g. clay liners, gas flue blocks
•   Designed to minimise disturbance to the household during installation
•   Tested to temperatures of 2000 degrees centigrade
•   Guarantees to survive a chimney fire
•   No acidic content, withstands acidic condensation
•   Increases the draw of the fire, as flue gases travel faster through the flue
•   Keeps the sectional area of the flue

Leaking chimneys
 The ravages of time, wind and weather, condensation, frost damage and chimney fires are some of the reasons why chimneys start leaking.  Leakage can give rise to a number of problems, such as the smell of smoke indoors, inadequate up-draught, the risk of fire or carbon monoxide poisoning.

Chimney cleaning
Before starting the sealing and repair work, the chimney should be cleaned mechanically to remove soot, tar and loose particles with steel brushes.

Eldfast has been developed to meet today’s strict requirements and has all the characteristics you would expect of a modern lining and repair agent.

Sealing a chimney
After lining with the Eldfast method you will have a chimney that is leak-proof, very hard-wearing, completely fireproof, and gives a better updraught as a consequence.

Eldfast
 Is a ceramic material that does not contain lime or cement and can therefore withstand continuous exposure to extreme temperatures having been rigorously tested by BSRIA to conform to current Building Regulations & Requirements after the 1st April 2002 changes.
Utilising some adaptions to the installer’s tooling (for which Landyvent are seeking patent), even gas flue blocks can be cleaned and lined, making full use of the nominal coating thickness of the Eldfast system in order to retain those vital minimum flue measurements. Obviously this same benefit is applicable to several similar types of flue construction: e.g. concrete flue blocks & clay liners which can be lined and sealed using Eldfast.

A modern material:
ELDFAST is a wholly ceramic material composed of two elements: a refractory ceramic aggregate in powder form and a resin bonding agent that together create a "slurry" with adhesive properties when applied under pressure.

Traditionally, only materials containing water, lime / clay mortar or cement have been available to re-parge a flue internally, these materials are now known to be prone to acid attack and deterioration.

CHARACTERISTICS / BENEFITS

(1) Preserves X-sectional area:

Eldfast is an insitu applied lining, drawn through the flue by means of a "plug", leaving a 4mm nominal thickness of material on the flue face (see opposite for further details)

Masonry flue (for example)
Free gas area
Eldfast coating (nominal thickness 4mm)
A traditional cast in - situ coating

 As demonstrated above, Eldfast will follow the contours of the flue (although some rounding of corners is likely), rather than drastically reduce the free area, this is of particular benefit when wishing to retain future usefulness of the fireplace for open fires (requiring a minimum 8" / 200mm cross sectional area) or when dealing with smaller flue areas initially. 

(2) Minimal disturbance to decor

Eldfast is designed to be installed without the need to break into the flue externally, this is due to the "plug drawn" method of installation (see above).  Many other in-situ systems specifically require brickwork to be removed at regular intervals to centralise " formers" and enable lining around bends in the flue.

(3) Increases updraught

Due to the ceramic nature of the Eldfast, your chimney will gain certain advantageous properties following lining with the material:

 As the refractory aggregate does not easily let heat permeate though, it acts as an insulator, keeping the temperature of the gases passing through at a higher level and therefore reducing the likelihood of condensates within, (try to imagine space shuttle tiles inside your chimney!!).  This may also have some useful applications for thatched property owners, where the temperature at the point of intersection for flue and thatch can be considerably lowered from that achieved through only the brickwork.

 Also as the material fills over-jointing and missing parging within the flue providing a gas-tight surface, this surface will then dramatically improve up-draught as a consequence of its smoother gas passage.

(4) Temperature impervious

Again, a benefit derives from the ceramic nature of the material (and one that is particularly relevant to solid fuel users).  The results achieved under practical test conditions demonstrated that the product showed no signs of deterioration at temperatures approaching 2000 degrees centigrade - indeed, it would vitrify and effectively become stronger/harder.  Put into context, a chimney fire may generate 1100 degrees centigrade, your flue lining is guaranteed to withstand it.

METHOD OF INSTALLATION
Note: abbreviated for informational use only

(1) Inspection and preparation - Pre-installation survey.
To ensure a structurally sound flue, suitable for lining with appropriate weather proofing and termination height and type.
Carry out flue smoke test to highlight any defects.
Ensure suitability for intended appliance.
Health and Safety requirements of site.

(2) Cleaning the flue
Loose material is removed using steel brushes, heavy deposits are tackled with reaming tools or flails.

(3) Lining the flue
The material is applied by means of a "plug" inserted at the base of the flue opening - the plug is winched up into the flue to the point the lining will commence from (this is usually at the top of the gather in the case of an open fire, or where connecting flue pipes enters the chimney from a room heater).  Note: large gather areas may be spray coated where applicable.  Mixed material is poured in slurry form onto the top of the plug and continually "refreshed" as the plug is pulled through the flue, applying the lining under pressure to the walls.  The plug can be pulled through more than once if required to achieve a continuous lining within to the operator's satisfaction.

THE PLUG
Can be either a series of foam pads covered with a Kevlar jacket or a small (3ft) balloon attached to a self regulating compressor (used for flues that change in diameter or have limited access).  Both methods apply to the material to the flue face under pressure.

(4) The finished product.
The surface finish of the lining will normally appear slightly granular and may be ridged in appearance due to application by the Kevlar blanket (the Eldfast may mirror folds in the blanket).  The lining will harden by a gradual process of air curing (approximately 30 - 60 minutes after application, the material will appear to harden).  If there is a warm ambient air temperature with a steady up-draught through the flue (i.e. stove doors should be left open) the material should have sufficiently cured after two days.  Should the ambient air temperature be below 5°C, a 2kW electric fan heater could be positioned to assist curing.

On completion, the lining will be checked and a HETAS Certificate will then be issued to you within 10 working days together with the data plate. The data plate should then be located, as described, on the Certificate of Compliance.
