Dilworth Windows & Doors - Frequently Asked Questions

What causes condensation on windows?

Condensation, or "sweating," is a natural occurrence on all windows and is caused by excess humidity, or invisible water vapor, present in the air. When this water vapor comes in contact with a surface, which is at a cooler temperature, the vapor turns to visible droplets of moisture.

Our insulating glass units provide superior energy efficiency to reduce the potential for condensation. However, there is no such thing as a condensation-free window in high humidity conditions. Controlling the amount of moisture in your home is the most effective action you can take to avoid condensation.

Here are a few tips on reducing the moist air in your home:

  • Use fans in bathrooms, kitchens and laundry rooms to circulate the air.
  • Air out your home frequently by opening doors and windows.
  • Reduce the number of indoor houseplants, as plants increase humidity levels.
  • Use a dehumidifier to remove excess humidity from the air.

How does the performance of vinyl windows compare with that of other products such as wood?

The performance and longevity of vinyl windows compare very favorably to those of other building materials, and vinyl often costs less to produce. Vinyl windows and doors are rapidly capturing a major market share as more builders and homeowners learn about vinyl's outstanding value and economy.

Long-lasting beauty, low maintenance and excellent thermal efficiency ratings give vinyl windows a winning edge over other types of replacement windows. The vinyl compound is produced with extra levels of UV inhibitors to help withstand harsh weather conditions, and it is recyclable and environmentally friendly. Vinyl won't pit or peel over time with only simple care and cleaning, windows can keep their beautiful appearance for years to come.

What is an IG unit?

IG stands for “insulating glass” and is made of a lease two panes of glass separated by a spacer.  The quality and performance of the IG unit is dependent on the glass used, the material of the spacer, and the insulating materials that are used in conjunction with the spacer.

What is meant by; “R-Value” and “U-Value”?

R-value is the resistance a material has to heat flow. As the R-value increases, the amount of heat-flow decreases.

U-value is the amount of heat transferred through a material. The lower the U-value, the slower the rate of heat flow and the better the insulating quality.

How does insulating glass improve the quality of the windows?

  • Improves the performance of the U and R values of your new windows and doors
  • Reduces condensation 
  • Helps keep the heat in and cold out during winter 
  • Helps keep the heat out and the cold in during summer

What is Low E/Argon filled glass and how does it work?

Low E (Emissivity) Glass is glass with a transparent metallic oxide coating applied onto or into a glass surface. The coating allows short-wave energy to pass through but reflects long-wave infrared energy, improving the U-Value.

Argon Gas is an odorless, colorless, tasteless, non-toxic gas that is six times denser than air. It is used to replace air between the glass panes to reduce temperature transfer.
