Historical Applications Accuracy

Historical Applications Accuracy

It is of prime importance to replicate the original building. A challenge comes with finding historically accurate products and meeting current building codes. Years ago, people did not use products such as plastic shakes, vinyl siding, and concrete tiles, Wood was the building material of choice, and wise project leaders are still specifying wood. The CSSB can help with period-correct specification of cedar shakes or shingles, assist with application information, and source the proper finishing products relevant to the era of specific historical projects. The CSSB also has contacts in the building official community and highly recommends you contact them for project approval guidelines, possibly including variances for specific historical projects.

Custom Dimensions Available

CSSB member manufacturers offer specialty products to meet the needs of historic project managers. Dimensions that exceed “stock" sizes can be sourced through the CSSB's extensive member network. Key historical products that are available: Tapersplit shakes, in various lengths up to 36″ and beyond. Straight Split shakes, in various lengths up to 36″ and beyond (Straight Split shakes are also known as Barn shakes). Shingles are available in various thicknesses upon request.

Tavern Restoration - Connecticut image

Tavern Restoration - Connecticut

Ashford, Connecticut is home to a very special 5-acre parcel of land. Originally part of a larger 60-acre estate, the property contains a house once used for 19th Century summer parties. Playing horseshoes and enjoying family gatherings were popular pastimes, proven by antiques, historical documents and photos found on site. From 1929 -1979, the home stood vacant, boarded up and quite forgotten, likely to avoid inheritance taxes. As the years passed, sheep were raised on the surrounding land. It seemed inevitable that the home was destined to eventually fall prey to a bulldozer.
