Retro Insulation: A Smart Upgrade for Energy Efficiency and Building Protection

Energy efficiency, indoor comfort and moisture management are vital aspects of retaining long term performance of any metal building. In addition to roof systems, structural members and exterior finishes, insulation for most property owners go unnoticed until problems arise. For older buildings or compromised systems, retro insulation provides an excellent alternative to reconstruction.

Retro insulating a building can significantly improve the thermal efficiency of the building, reduce energy bills, provide a more comfortable environment and reduce costly asset damage. MetalGuard‘s retro insulation solutions enable building owners to obtain the maximum value from their current investment.

What is Retro Insulation?

Definition of Retrofit InsulationRetro insulation involves upgrading, replacement or addition of insulation to an existing building for insufficient or non-functional insulation. Retrofit insulation, therefore, includes installation of insulation to an existing building, as opposed to during the construction process.

Approximations of existing insulation levels include the fact that many older metal buildings were built to lower insulation standards than what is now required. Insulation may have degraded, become compressed, absorbed moisture and lost some of its insulating properties. Retrofitting can enhance performance of existing structures without full replacement of building envelope.

This modernization compensates for the loss of efficiencies and contributes to overall building durability and functionality.

Why Older Buildings Need Retro Insulation

Aging insulation systems cannot always meet the performance needs of modern building operation. As insulation ages, its heat transfer performance intensifies, rendering stable indoor climates more difficult to achieve.

Hotels and offices that lack proper insulation may cost more to run as warm air or cold air needs to be pumped in more often for the heating and cooling systems to perform efficiently. Temperatures can also vary often leading to a discomforted environment for employees, visitors or their goods.

When insulation performance drops, the control of humidity becomes another area of concern. Condensation caused by poor insulation might cause damage to structural elements, equipment, and interior finishes.

Retro insulation reduces all of these problems by reinstating the thermal barrier and optimizing the performance of the building.

Key Benefits of Retro Insulation

Improved Energy Efficiency

Insulation in the retro insulation system minimizes required energy loads. Energy requirements decrease as heat transfer through the envelope is diminished.

This enhanced thermal property can lead to lower utility bills and less stress on the heating and cooling systems.

Enhanced Indoor Comfort

Buildings that are not well insulated can have hot and cold spots in different areas within it. Retrofitting insulation allows the internal temperature to become more uniformed and improve Comfort for the people inside.

Better Moisture Control

Good insulation prevents excess condensation due to differences in temperature between interior and exterior walls. Insulation decreases the effects of moisture on the materials through protection from mictures, corrosion, and water damage.

Increased Building Value

Buildings with lower operating costs tend to be more desirable to buyers, tenants, and investors. Retro insulation can help increase the value of property while showing a dedication to the building‘s long-term performance.

Common Signs That Retro Insulation Is Needed

The following are some warning signs that insulation upgrades should be considered.

Warning Signs

• Increasing energy prices are frequently one of the first signs of a problem.
• If utility bills are rising despite regulated consumption, insulation may be providing too little protection against energy loss.
• Temperature differences indoors might be a symptom of the insulation situation as well.
• If certain parts of a building tend to have higher or lower temperatures compared to the rest, there could be a problem.
• Other warning signs include any dripping or condensation on ceilings, walls or on structural steel.
• Indicates that there is too much moisture therefore the insulation may not be doing its job.
• Further signs that the building could potentially benefit from retrofit insulation are drafts, running the HVAC system for extended periods of time and pink, yellow or brown staining of the insulation.

The Relationship Between Insulation and Roofing Systems

Insulation and roofing systems are co-dependent and must function as a system to provide a high performing building enclosure. Excellent insulation performance cannot be achieved if the waterproofing or air barrier element of the roof is compromised.

A leaky roofing system results in wetting the insulation materials and a big drop in its thermal efficiency. Water logged insulation is very effective and might lead to the growth of fungi, corrosion and structural damage.

Due to this relationship, roof inspection is done in conjunction with insulation assessment. This combination solves the problem of water intrusion coming from different directions and would ultimately lead a long lasting building.

Why Metal Roof Leak Repair Is Critical

Water intrusion through roof leaks is perhaps the single biggest threat to good insulation performance. Repair of metal roof leaks in a timely manner is one of the most important steps to insure insulation protection and avoid building damage.

Even small leaks will add moisture to the insulation over time if they go unnoticed. Once the insulation has become saturated its resistance to heat transfer will be severely reduced. Moisture in the insulation can also result in corrosion and the decay of supporting structures.

Leaks from professional metal roof leak repair can be identified and corrected before they allow water to damage the insulation performance of the building. Building owners can thus take control of leak situations and help prevent the need for more costly repairs.

How Retro Insulation and Metal Roof Leak Repair Work Together

In historic buildings, insulation replacement and roof repairs are more successfully undertaken when integrated into a comprehensive renovation program.

Prior to the installation of retro insulation, roofing systems should be checked for potential leaks, compromised flashing, failed sealants and drainage issues. Any metal roof leak repair should be completed prior to installation so as to not compromise the condition of the new insulation.

This comprehensive solution offers many benefits. Better insulation decreases energy wastage and roof repairs ensure the building remains protected from subsequent dampness. In essence the two together, provides a robust enclosure.

Property owners tend to receive more energy savings and lower maintenance costs if they combine covering both systems.

The Retro Insulation Process

Step 1 Building Assessment

The retro insulation program involves a building assessment that. The technician then assesses the state of the existing insulation, pinpoints under performing areas, and plans the optimal retrofit.

Step 2 Roof Inspection and Repairs

Inspect roof systems for leaks or moisture issues impacting insulation during this phase. Any required metal roof leak repairs are done prior to insulation installation.

Step 3 Insulation Upgrade

After any traces of damp have been cleared, new insulation types may be added in or existing insulation upgraded to improve thermals. This will depend on the building form, the state of the current insulation and the required level of perforamnce.

Step 4 Final Evaluation

A final evaluation can be used to check that the upgraded system is working correctly and achieving the goal.

Long-Term Maintenance for Maximum Performance

Once retro insulation has been upgraded, its performance can be maintained through ongoing maintenance.

Maintenance Guidelines

• Scheduled roof inspections are still valuable for finding small leaks before they reach the insulation.
• Periodic review of condition of the insulation can highlight small problems before they develop.
• It is advisable for building owners to measure energy consumption, the indoor comfort condition and indications of condensation to maintain the requirement of optimum functioning for ventilation systems.
• The owner should respond to the maintenance problems quickly, so that the lifespan of insulation and roofing could be prolonged.

Taking preventative measures to reduce damage is one of the best means of ensuring a buildings long-term performance.

Conclusion

This is one of the most popular retrofitting options for existing metal buildings as it not only adds energy savings benefits, but also improves comfort and long-term durability.

Note, however, that the effectiveness of insulation is largely dependent on the condition of the roofing system. Its crucial that metal roof leak repair performed quickly to avoid the risk of moisture damaging the insulation, and subsequently incurring structural damage.
