Minnesota State Capitol

Classic Accoya windows

Minnesota State Capitol

The majestic State Capitol building in St. Paul, Minnesota was in a state of deterioration: on the outside, the regal marble exterior design, completed in 1905, was crumbling.

The state embarked on a $272 million, four-phase restoration plan in 2013, with tasks including replacing plumbing and electrical systems, boosting energy efficiency, improving access, replacing the roof and repairing all of the crumbling stone.

Another major part of the project was restoring the building’s original wood windows, which had been covered over with aluminum windows 30 years ago with Accoya wooden windows.

Re-View, which specializes in historic window restoration and re-creation, sent a crew to Williamsburg to remove one of Chandler Hall’s originals and haul it back to Kansas City, where engineers dismantled it piece by piece and then reconstructed it using Accoya wood and other modern materials.

Tested to the limit

60 year Service Life
Thermal performance

After running tests and reviewing exterior and independent data, the BRE concluded that Accoya wood, provided best design practice is followed, has a service life expectancy of 60 years when used in exterior applications such as timber windows, doors, siding, wooden window frames and balconies. The BRE stated that Accoya wood shows excellent durability and stability properties. This position has been positively corroborated by TRADA and Heriott Watt University / Imperial College London conducting similar service life reviews.

Accoya is also recognized by WDMA Hallmark Certification Program.

Accoya thermal conductivity has been assessed by IFT Rossenheim, Germany in accordance with EN 12664 and then developed into the required declared value format, under the most rigorous European assessment methods by the EN ISO 10456: 2008 procedure for determination of declared and design thermal values.

In comparison to other standard wood types for joinery, Accoya thermal conductivity is:
› Superior to softwood by 8%
› Superior to hardwood by 30%

These improved levels provide options in design, in terms of achieving a higher U- value for the same window design by switching timber type, or alternatively using
a more preferred aesthetic or production friendly design without significantly compromising energy efficiency.
