You have no doubt heard about the advantages of using charred timber cladding in Australia, as it is the perfect process to provide timbers with long term durability. Besides, it offers a long term maintenance free colour fast option. External timber cladding offers an immensely versatile option that enables you to create structures that are not only durable but reflect a natural appeal. This makes our charred timber wall cladding solutions a superior choice.
The charring process creates a carbon crust that is U.V resistant and not susceptible to “Silvering out”. It is also well documented that the charring process improves timbers durability and resistance to insect attack. Best off all it looks great!
Eco Timber only uses Australian hardwoods, all of which attract a BAL 29 fire rating, and are class one durability, perfectly suited for most properties and areas.
Typically, the species we use are Red Ironbark, Queensland Spotted Gum and Blackbutt. All external cladding is pre-oiled following the charring process with Cutek CD50 (penetrative oil).
Any internal applications are sealed with a Matte water based polyurethane to prevent carbon residue coming off the surface and marking people or items.
Lead time is typically two (2) to three (3) weeks following a confirmed order and up to 4 weeks on set length orders.
The material comes in a random length specification or set lengths at an additional 40%.
Our Profiles include:
Nominated finish can be either our “Standard” or “Deep” ( crackled) Charred finish when ordering.
- 120×19 secret fix t/g, end matched
- 70×19 secret fix t/g end matched
All our shiplap is profiled with an 8mm rebate.
“3D” shiplap profiles are a combination of mixed width and mixed depth profiles. All the profiles are T&G for improved stability;
The “3D” shiplap profiles are inclusive of:
- Profile A: 120×19 t/g
- Profile B: 80×28 t/g
- Profile C: 60×42 t/g
- Profile D: 35×32 t/g
Charring of timber screens battens, posts, singular “3D” cladding profile selections and custom profiles are also available upon request.
FIXING - Our preference is always to pre drill and screw fix through the tongue side of the cladding using a minimum 8 gauge screw with a black powder coated head OR consider BLACK HEADS by ECO TIMBER GROUP self drilling screws ( 10 Gauge /stainless self drilling screws)
Perfect for this application in face fix or secret fix profiles, at a recommended 400-450mm centres. It is also our preference that a 42-45 mmx19mm or greater hardwood batten be applied to the stud frame, over your moisture membrane, for maximum purchase ( 45-70 x32-42 on masonry based sub walls) .
Over longer wall runs over 8m + long, the use of an expansion joint is recommended – USE a 10mm packer between the standard 8mm rebate of your board, to create an 2mm ease on every 4th-5th meter board interval to elevate expansion issue in colder weather or southern / eastern pockets of the build.
With all Horizontal installed boards you must also silicone the end match or butt join / mitre lapp to avoid any potential moisture permeating behind the board.
For all our 3D cladding, a galvanised/ stainless steel brad fixed through the tongue at 45 degrees is recommended accompanied with a suitable weather proof construction adhesive at a minimum or a screw fix ( using “BlackHeadz“)
COATING – Once the cladding has been installed, we recommend one coat of BlackASH CUTEK extreme preservative be applied prior to handover. Ensure you have sealed all exposed end cuts and fixing blemishes from the install process also to help minimise moisture induction into the end fibres of the selected timber finish.
RE-COATING – Our suggestion is that the timber should be re-coated at least every 5-7 years ( charred timber only) to help re-hydrate the timber, despite it’s Class 1 durability, this will assist in maintaining the timbers natural dimensional integrity and minimise any crack or checks over its lifetime for optimal performance.
Cutek is a penetrative oil and each coat builds within the timber and protects from within, with its unique copper mineral treatment, it lives in the body of the timber and builds upon each re-coat. Any non charred timber will need to be maintained more periodically pending its orientation and your desired effect ( maintaining the tone of the timber vs. letting it naturally weather out) this may be every 8-14 months or simply as often as necessary.
CHARRED FIXINGS – ECO TIMBER BlackHeadz are our new 10 guage self drilling, stainless steel, 50mm trim head screws, developed for our Charred timber and cladding systems.
Currently available in boxes of 500, Blackheadz have the ability to self-drill into timbers that are 8.6 janka rating and above, to expedite the installation process, whilst disguising the stainless head for all application methods of our cladding.
Please note: Due to current Industry conditions RE BushFires /COVID restrictions and its impact on the mills and processes, expect delays on lead times and prices are be set to increase in EARLY 2021, based on source suppliers logging rates, feedstock thickness availability, please specify timber products, species and quantity and request a new quote to ensure you have the most accurate and up-to date prices at the time of your next enquiry.
