On 21st Dec 2009 we inspected the windows in the Royalty Building, Douglas, Isle of Man. Our findings and recommendations are as follows.

## Current Windows.

The windows in this property are traditional wood sliding sash windows. They are of Georgian style with typically 9 panes of glass per sash. They also have sash horns fitted to exterior and interior. Most have been repaired on at least one occasion previously.

The majority of windows in this building are in a serious state of decay. We located numerous areas in which the timber in both sashes and frames was deteriorated beyond repair. There is also extensive damage to glazing throughout the building.

## Examples of Sill Damage

Examples of Frame Damage

## Recommendations

In our view the window frames currently in place have suffered such widespread deterioration over time that they are now damaged beyond repair. There have been attempts to replace defective timber in the past but these have not been totally successful. Joints in the timber will always be visible and will eventually open and allow moisture penetration to both the original frame and the timber used in the repair resulting in further damage. In time more and more timber will be lost to decay. At best, repairs will only be a temporary solution. Although we would be quite happy to carry out a thorough refurbishment to the windows we could not provide any guarantee to the works and would not recommend this course of action.

In relation to expectations on the performance of windows in today's buildings, these windows can never deliver the energy ratings demanded by current building standards. Heat loss through these windows will be considerable and air penetration from the exterior will be significant in reducing the suitability of these windows in this exposed location.

We would strongly recommend the installation of new wood sliding sash windows throughout the building which will deliver the stringent performance standards expected into today's market. This would also eliminate the need for ongoing repairs. Although performance is important it will also be very important that they retain the historic nature and character of this traditional building.

A well designed window can deliver both performance and authentic styling and offer a much superior solution for the windows in this building.
