A Brief History

The project entails repairing the building at 335 Maplewood Ave in a manner that meets both preservation and sustainability goals. The building is the new location for Petersen Engineering, a firm that has been located in Portsmouth since 1992, and specializes in sustainable building engineering. We intend for this project to showcase techniques & materials that promote both preservation and sustainability and intend to share all aspects of the project locally and regionally through open houses, presentations, industry tradeshows, case studies and publications. We foresee this project being a valuable educational tool to demonstrate that preservation goals need not be compromised by sustainability goals. We have teamed with Bruss Construction who we know from past collaborations has exceptional experience and expertise on projects with the dual goal of preservation and sustainability.

The project received approval by the Historic District Commission on January 6, 2010 with construction scheduled to begin early February 2010.

The projected peak heat loss reduction is 85%.

What is that yellow stuff?

People driving by stop and ask all the time: "What is that yellow stuff on the wall?" and "What does it do?"

It is called Home Slicker. It is a plastic mesh that goes on behind the siding and creates a little air gap.

Why do you want that?

1. It helps quickly drain and ventilate moisture out from behind our siding.
2. It serves as a capillary break between our siding and Tyvek.
3. It provides pressure equalisation behind the siding (to help keep wind driven rain from being drawn into wall)











The bottom of the Home Slicker is exposed to daylight. To keep bugs from crawling up the gap created by the Home Slicker, screen is wrapped over the ends. (See below)

  1. The only thing we humans can bring back time is by not assuming that Time machine does exist, but by taking a step to physical things such as touching the old ones to make it new again, to make it more visible so that we can take a leap back to yesterday. In this case, there is renovating and restoring. I grew up in a place where then baseball fields exists, an alleged haunted house is restricted, and bakeshops with tatty settee rules the county - now replaced by sturdy building and humongous walls hiding the past as if my childhood is a little piece of unimportant shelf. I was raised in Calgary - roofing company, chimney cleaner, milk and newspaper deliver boy were those common people of its simple and diverse community. That is why I highly offer my adoration to those who restore old structure, because they restore not just the structure but old memories as well. They are not just re-sculptors of history coffee table books but they renew childhood. Their works, they always reminds me of my lost Calgary, roofers and fixer of the few drops of memories in my lonely ceiling.
