HAI by reSAWN TIMBER co. features CHARRED CYPRESS burnt in the Japanese style of shou sugi ban.  HAI is recommended for interior wall cladding – please call to discuss exterior applications. HAI is available in select grade or #2 common grade cypress.  The higher the grade, the better it is felt the wood will perform.  See our CHARRED Grading Guide for more info.  HAI can be treated to Class A Fire Rating for Interior Application – please call to inquire.

HAI is carefully charred, misted with water, cooled, brushed and then stained/sealed.  The top coat sealer is applied prior to shipping (for exterior applications, we recommend sealing the back side as well as the face).  The burning process accentuates the wood grain and creates varying colors when viewed from different angles and in different light.

HAI is made with cypress sourced from the Southern United States and can be used for interior wall cladding and ceiling cladding.  With its legendary beauty and natural durability, cypress has long been a staple as an exterior wood siding product.

When evaluating resiliency with CHARRED materials it is a trade off – the heavier the char the more weather/rot resistant as is the intention of burning the wood, however, charcoal is soft, especially on a soft wood. From an impact perspective brushed designs (such as KUJAKU, HADAKA, AKA etc.) will be more impact resistant then MOYASU or HAI as the char is only on part of the wood. HAI and MOYASU are fully CHARRED CYPRESS and best suited for interior applications. HAI is the least impact resistant of the CHARRED materials due the deep charring (approx 1/8”). We do not recommend HAI or MOYASU if your desire is to have the original CHARRED face remain indefinitely. The charcoal layer is a soft, sacrificial wear layer and will flake & wear off over time, changing the aesthetic and revealing non-burnt cypress. Rather, we suggest KURO or MONOGATARI, two alternative black designs that are brushed, burnt & finished with a black stain. MATSU on Accoya is more durable and should be considered.

Our charring & sealing process makes for beautifully designed exterior wood siding.  Like any exterior wood siding prefinished or finished in place, these materials will weather naturally over time and will require maintenance.  For interior applications, expect little to no change.  We’ve created this CHARRED USAGE GUIDE to tell you more.  

reSAWN’s CHARRED offering features cypress, western red cedar, Accoya, Kebony, black walnut, red oak, white oak and reclaimed hemlock that is burnt in the Japanese tradition of shou sugi ban.  Our award-winning CHARRED products pay homage to the traditional Japanese technique of “shou-sugi-ban” aka “yakisugi” without being literal.  Historically very specific in their definition, “shousugi-ban” and “yakisugi” have become common nomenclature for modern charred wood designs in general.  All of reSAWN’s CHARRED products are made in the USA, in our facility in Telford, PA.
