Remodelling facades

Change of use of existing structures often require physical changes to external fenestration to completely re-shape the structure into a form more suitable for its new use. Thermal performance criteria also need to change in line with the intended occupancy.


1. Changing the property's use

Buildings originally designed as offices may need window openings and intervals re-designed when changing the property's use.

Complete remodelling to cover over alterations and upgrade the overall appearance of the facade is often required.

2. Poor insulation in walls

Due to increasing requirements for thermal insulation, buildings undergoing change of use may often require upgraded insulation in walls.

A decision needs to be made regarding the positioning of new insulation. Cavity sizes are restricted and internal insulation reduces the floor space available for use.

3. Heat loss through walkways and wing walls

Some features, especially those that puncture the facade e.g. wing walls and balcony walkways can provide thermal spikes and cold spots that are subject to condensation internally.

Condensation leads to other problems such as mould growth and musty odours in environments that are becoming more and more enclosed in order to reduce heating costs.


Re-fenestrate and insulate exterior of building

Use steel framing and external sheathing board to re-fenestrate and external wall insulation to protect, insulate and upgrade the structure's facade. In doing so, the whole construction is kept warm with condensation risks and cold spots eliminated.
