[MassHistPres] Historic House Insulation Contractors - Central Massachuse...

[Jill Fisher]

Holes should NEVER be drilled into the exterior walls - unless you think the polka dot look enhances the historic character of the building. (Despite what some contractors claim, they cannot be patched perfectly and will become more pronounced over time.)  The proper technique is to remove the clapboards to allow for insulating from the outside & then replace them.

Gregg, 
You need to be careful regarding the type of insulation you use and the contractor. In order to install the insulation, holes will have to be drilled into the walls and the insulation will be injected into the wall cavity. Once the insulation is injected into the wall, it will become a rigid mass. Any pipes or wires will be locked into place and you will create problems if you need to repair walls or pipes/wires inside the wall. You should also determine if the insulation is a moisture barrier and how it will affect the wood. Blown in cellulose treated with borate's can also do the trick, but does not become rigid after it is placed inside the wall.Celluose(usually recycled newsprint) is more enviremently friendly than blown insulation (petrochemical based).In any event holes will still be drilled into the wall for this type of insulation. Also check into possible rebates for this project or any other type of energy retofit.This rebate program is usually available after an energy audit provided by the local electric or gas provider. Please feel free to contact me if you have any questions.
