The failure of exterior walls invariably results in discomfort to the occupants of a building, hence the need to ensure that this assembly is functionally adequate. Issues arising from poor performance of the exterior walls usually reveals through various surface defects. Exterior walls form the largest part of a building enclosure and provide crucial functions to the built environment. They separate indoors from outdoors and, perform many critical functions such as:
- Control water / vapor flow.
- Control heat flow through insulation.
- Control rain penetration.
- Control air flow.
- Control light and solar radiation.
- Control noise.
To meet these functions, exterior walls must have adequate structural strength, be durable and economical. In addition, exterior walls form the major appearance feature of a building. Unlike windows and doors that are compartmentalized into discreet and separate units, exterior walls are continuous and come as one entire wall assembly.
Assessment of Performance Problems
The failure of exterior walls invariably results in discomfort to the occupants of a building, hence the need to ensure that this assembly is functionally adequate. Issues arising from poor performance of the exterior walls usually reveals through various surface defects such as:
- peeling paint.
- efflorescent stains.
- decayed wood
- mold or mildew on interior surfaces. etc
Key factors include exposure to rain, sensitivity of the wall assembly to moisture, and the quality of the details. PEG’s team of experts has been in the forefront of exterior wall investigation, design and repairs covering all types of exterior walls (brick, precast wall systems, EIFS, metal cladding etc). PEG has kept pace with technological advancements to ensure that the solutions we recommend are innovative, cost effective and durable.
Replacement Planning
Once the decision to replace re-clad or repair an exterior wall is made, PEG will proceed into the design phase. PEG ensures that every opportunity is taken to improve on the durability and life span of the repair/replacement including ensuring that repairs are cost-effective. PEG will also appraise the following:
- Are there opportunities to improve energy performance?
- What type of exterior wall re-clad assembly should be used?
PEG works with the Client through all stages, ensuring that all design decisions are comminuted to the Owner in a timely manner.
