Watch cooling costs drop after the installation of window film on your building or storefront. Window film is a low-cost way to help reduce both solar heat gain in the summer and heat loss in the winter. In addition to performing great window film installations, Campbell Window Film offers other services including complimentary consulting, energy analyses and utility company rebate assistance, just to name a few.
Window film may be a good first choice of energy retrofits, not only because it costs less than many other measures, but because it can be installed quickly with no disruption to daily business and has an immediate impact on energy bills. Window film may also eliminate or delay the need to replace HVAC (Heating, Ventilation, Air Conditioning) systems and reduce the size and capacity requirements of future replacement units.
How it Works
Window films reject as much as 83% of the sun’s heat by causing it to bounce off of the glass and back out away from the building. This can translate into a savings of one ton of air conditioning for every 100 square feet of glass filmed. Regular glass without film will allow the heat to pass through to the interior spaces where it accumulates. This accumulated heat is often referred to as heat load and must be pumped out of the building by the HVAC system. Window film reduces the heat accumulation which equates to less energy needed to power the HVAC equipment.
During the winter the same film will help retain interior heat, reducing heating costs by 20% to 30%. The return on investment is often less than two years.
Most utility companies in Southern California, including SCE, LADWP, and SDG&E offer rebates for installing window film which can cover between 1/3 – 1/2 of the total cost of installation. Campbell Window Film works closely with the utility companies and will prepare the paperwork and submit your application for you.
Understanding how much energy will be saved and what cost savings will be realized is a key element to making a sound investment decision. It is also often a requirement to qualify for utility rebates and tax incentives.
Campbell Window Film will survey your building to determine envelope construction, HVAC systems, internal loads, schedules, air infiltration, building orientation, and other factors. Using sophisticated energy modeling software such as EnergyPlus or eQuest, we will run before and after simulations to determine energy savings and ROI. These reports are provided as part of our comprehensive proposal process.
Proof of Technology
To help our clients feel confident that we have an effective solution for their building, we offer our proof of technology analysis – a testing method that utilizes electronic temperature sensors and BTU meters to document the effectiveness of our window film solution on your building. Test data is compiled and presented in a report which can be used in conjunction with the energy analysis to aid in the decision making process.
Protection from fading
The sun’s ultraviolet rays can wreak havoc on a building’s interior furnishings, wood, carpet and artwork, fading them and shortening their useful life. Our window films filter out 99.9% of harmful rays to dramatically reduce fading.
Some buildings have too much sunlight at certain times of the day causing annoying glare and problems viewing computer screens. Unlike blinds or curtains that block the view completely, window films reduce harsh glare while maintaining an open feeling and a clear view out.
Our spectrally selective Prestige Series window films are ideal for retail stores because they provide a clear unobstructed view in during the day and night, making merchandise completely visible from outside the store. This technologically advanced film lets in the daylight while rejecting 97% of sun’s infrared heat and 99.9% of the UV rays that destroy display merchandise.
Window films are generally installed on the inside surface of the glass, but in recent years exterior film technology has advanced greatly and its use is becoming more common. Higher solar heat rejection can be achieved with exterior films and installation is often faster. Until recently, the reason why exterior films have not been widely used is because the lifespan is not as long as an interior film due to its exposure to the elements. With improved technology and longer warranties, exterior films are becoming more popular with architects and designers.
Exterior Film May Be Recommended For:
- Glass that cannot be accessed from inside the building
- Laminated glass
- Boosting performance of pre-treated glass
- The enhancement and modernization of aged glass or damaged glass
All of our 3M Window Film products come with extensive manufacturer’s backed warranties that cover the window film as well as the glass.
