Care & Maintenance

photo-care

Vytex replacement windows and doors are designed not only for beauty, comfort, and energy-efficiency—they’re also virtually maintenance-free:

  • Glass can be cleaned with household glass cleaners.
  • Vinyl can be cleaned with nonabrasive household cleaners or soap and water.
  • Painting is not required. The color of the Vytex window is solid through all window components.
  • Lubrication is not required. All moving parts are self-lubricating. Rollers are made of metal for long-lasting, trouble-free performance.

Use the following information to easily operate your quality replacement windows:

How To Read The Sticker

All ENERGY STAR®

Qualified products must be tested by an independent lab to determine the products’ performance ratings. The National Fenestration Rating Council (NFRC), an unbiased government-authorized entity, reviews these ratings, which provide the basis for ENERGY STAR® window performance requirements and helps consumers compare the performance of various window brands and types. Look for low U-factor and Summer Solar Heat Gain Coefficient (SHGC) numbers for highest efficiency performance.

Winter U-factor

The lower a window’s overall U-value, the less heat you will lose through that window. A lower U-value means you’ll use less energy to heat your home in the winter.

Summer Solar Heat Gain Coefficient

A lower SHGC means less solar radiation is admitted through your window. Your home will remain cooler in the summer and your air conditioner will not have to work as hard.

Visible Transmittance

Visible Transmittance (VT) measures how much light comes through a product. The higher the visible transmittance, the clearer the piece of glass.

Air Leakage

Lower numbers mean fewer drafts and less air infiltration. The lowest number the government assigns is a .1; windows with an air leakage number above .3 fail this test.

Condensation Resistance (CR)

The higher the CR rating, the better the product is at resisting condensation formation on the interior surface of the product. While this rating cannot predict condensation, it provides a method of comparing the potential of various products for condensation formation.

Condensation

What It Is – and What You Can Do About It

Replacing drafty windows with Vytex’s high-performance windows will reduce airflow in your home and make it ‘tighter.’ And while tighter homes retain warmth, they also retain humidity, causing fog or dew to appear on windows, usually in the colder months. This condensation usually appears near the bottom of the window sash, because the glass near the sash is the coolest surface. Condensation is not indicative of a problem with your new windows’ installation or construction—rather, it’s a testament to their superior efficiency.

A little condensation is normal and will not damage your new windows or home. It simply means that the humidity in your home is too high, and you need to reduce it until the condensation disappears.

Here are steps you can take to reduce condensation by controlling humidity and increasing air movement in your home:

  • Use exhaust fans in your kitchen, laundry room, and bathrooms. Consider installing an exhaust fan in your attic to draw out moist air.
  • Use a dehumidifier and discontinue using furnace humidifiers and other humidifying devices.
  • Air out your house for a few minutes each day by opening a window or exterior door.
  • Vent gas burners, clothes dryers, etc. to the outdoors.
  • Be sure that the ventilating louvers in your attic, basement, or crawl spaces are open and amply sized.
  • Open fireplace dampers to allow moisture-laden air to escape.
  • Move houseplants to a sunroom or other infrequently used room.
  • Waterproof your basement floors and walls with moisture-sealing paint and moisture barriers.


Condensation Occurrences
