Outdated windows and deteriorating masonry facades allow intense solar radiation and moisture to penetrate your facility’s defenses. Upgrading your building’s glazing and exterior sealants is a powerful way to reduce peak cooling loads and protect structural integrity. E3 implements spectrally selective window films and comprehensive curtain wall restorations to modernize your envelope. These strategic upgrades enhance occupant comfort while delivering measurable, budget-neutral energy savings.
Spectrally Selective Window Films
Standard commercial glazing allows massive amounts of solar heat to enter classrooms and offices, causing severe temperature imbalances. We install advanced spectrally selective window films that reject intense infrared heat while allowing visible light to pass through. This innovative technology significantly reduces cooling demands without sacrificing beneficial natural daylighting.

Curtain Wall Sealant Restoration
Aging curtain walls and structural brickwork eventually suffer from degraded sealants, exposing the building to severe water intrusion. Our crews meticulously remove failing caulking and install high-performance elastomeric sealants across the entire facade. This rigorous restoration process protects your structural masonry and prevents expensive long-term water damage.

Glare Reduction and Occupant Comfort
Unfiltered sunlight not only heats up a room but also creates intense glare that disrupts learning and productivity environments. Our window glazing solutions actively mitigate harsh glare on screens and whiteboards across the facility. By stabilizing room temperatures and light levels, we create a dramatically more comfortable space for all occupants.

Extending the Life of HVAC Systems
When solar heat gain is left unchecked, perimeter HVAC units are forced to operate continuously at their maximum output. By reflecting that heat at the glass, we alleviate the heavy burden placed on your mechanical cooling infrastructure. This proactive envelope defense extends the operational lifespan of your critical facility equipment.

Frequently Asked Questions
Do window films make the building interior dark?
No, we use spectrally selective films that are designed to block heat-producing infrared rays while allowing the majority of visible light to enter. This ensures your facility remains bright and naturally lit while staying significantly cooler.
How often should building facade sealants be replaced?
Commercial sealants typically degrade over 10 to 15 years depending on UV exposure and structural movement. Regular inspections are necessary, and proactive replacement prevents costly internal water damage and energy loss.
Can window glazing be funded through energy savings?
Yes, window films provide a substantial reduction in mechanical cooling loads during peak summer months. These verifiable energy reductions are calculated into our performance contracts, allowing the upgrades to pay for themselves over time.
