What You Need to Know about IGUs on Replacement Windows

replacement windows in El Cajon, CA

Windows are one of the weakest links in the exterior envelope of your home and the common culprit for air leaks and energy losses. So if you want to start saving energy, windows are a good place to start. These devices of glass, framing material, and moving parts are exposed to some brutal elements. Insulating glass units (IGUs) on replacement windows in El Cajon, CA go a long way towards increasing the efficiency of these products. Here is what you need to know about this standard window technology:  

What are Insulating Glass Units?  

The reason it is called a unit is because all the parts depend on the others for the highest level of insulation. The five primary components of IGUs include multiple panes of glass (typically two or three), spacers, inert gas fills, sealant, and the window frame. Here is a quick breakdown of each feature:  

  • Glass: The standard for modern windows is two panes of glass, but some windows feature three or even four. Thickness ranges from 1/8” to 3/8” in various applications. Clear glass is most common, but homeowners can also choose tinted, laminated, low-E, reflective, and decorative coatings on the glass.  
  • Spacers: The spacer separates the panes of glass where they meet the frame so they remain held apart at an appropriate distance. Aside from that, the spacer also accommodates stress from pressure differences in thermal expansion and contraction. Spacers are usually aluminum with a desiccant coating to help absorb residual moisture. Spacers vary in width depending on the type of gas between the panes.   
  • Gas Fills: Each manufacturer uses a unique formula for the gas between the glass. Argon, krypton, and xenon are the most common. These noble gasses are chemically non-reactive. They have more density than normal air and improve the efficiency of the IGU.  
  • Sealant: To hold the unit together manufactures use two sealing systems. A single-seal system uses organic sealant, typically butyl material to seal the spacer to the glass. A double-seal system also has a butyl material behind the spacer but also has a secondary sealant, usually silicone, for extra strength.  
  • Window Frame: There are many variables to choose from, but perhaps the most important when making energy efficiency a priority is the frame material. Aluminum is strong and light, but more readily conducts heat. Wood windows are excellent insulators, but the maintenance on all wood window frames is expensive and time consuming. Vinyl window frames are some of the most affordable and are great insulators, but they don’t have the strength and durability of other materials. Fiberglass frames offer high thermal performance and strength and durability.  

Over Time IGUs Fail 

Eventually, the seals on IGUs will fail. This is due to a partial pressure differential between the noble class and outside air along with the thermal expansion of various materials. And if the seal fails it diminishes the efficiency of the window. Typically the noble gas leaks at a rate of about 1% per year. You might not notice right away, but over time moisture and particles will leech between the panes making the window appear hazy or foggy. And once that happens you need window replacement.

Most Common Reasons You Need Del Mar, CA Window Replacement

Del Mar, CA window replacement

Windows are an essential part of your home. They allow in light and ventilation, but also protect your home against intruders and the elements. But if your window breaks down it can result in drafts, high energy bills, moisture leaks, and a lack of protection. Any of these causes could result in the need for Del Mar, CA window replacement  

Poor Installation 

A top cause of premature window failure is a faulty installation. Some homeowners try to handle this home improvement on their own, but what they don’t realize is one small mistake during installation could render the new window completely useless. That is why it is important to leave the measurements and installation to the professionals. It is the best way to ensure proper fit and lower the risk of window failure.   

Improper Maintenance  

Another common cause of window failure is poor maintenance. Taking care of your windows means more than washing the glass. You should examine your windows once a month looking for signs of damage. You should also perform general maintenance tasks like clearing and lubricating the track to make sure operation is smooth and easy. And there is no need for harsh chemicals or abrasives. Clean your window frames with mild detergent, water, and a soft cloth.   

High Moisture Levels 

Moisture can cause rust, warping, rot, and mold. Fortunately, most window materials resist water damage, but you still want to be careful about condensation and leaks. Because while the water may not hurt vinyl, fiberglass, or aluminum windows directly, it can leak into the walls and floor causing structural damage to your home.   

Extreme Fluctuations in Temperature 

Most materials change structure, shape, area, and volume in response to temperature changes. And years of extreme temperature changes can break the seals on your windows, causing failure.   

Pest and Insect Infiltration 

In warmer regions, pest infestation can be a major problem for homeowners. Critters and insects who try to gain access to the home can cause damage to siding, windows, doors, and other structures of the home. That is why it is important to check windows and doors for signs of scratching, scraping, digging, or dry rot.   

Accidental Damage 

Windows can literally take a beating, and not just from the elements. The blunt force from a ball, toy, or piece of furniture can break the glass and damage window frames. Window repair might be an option, but for extensive damage, you might have to consider window replacement.   


Due to exposure to the elements, the materials on your windows will start to break down. Most windows last an average of 20 to 30 years before you start noticing moisture leaks, air infiltration, and higher energy bills. That is when you know it is time to upgrade to more energy efficient products.

Do I Want Single Hung or Double Hung Windows?

windows in Solana Beach, CA

Because it is a coastal climate, windows in Solana Beach, CA don’t usually last more than 25 years. You might one day look at your windows and notice they are starting to get old and worn. It might be time for replacement windows. And with that decision also comes an opportunity to change the window style to better match the style and functionality you want for your home. It is a big decision, and because windows are a large investment you want to have as much information as you can about your options. So here is what you should know about single hung and double hung windows:   

Single Hung Windows vs Double Hung Windows 

When most people picture a window in their mind, they invasion these window styles. These are some of the oldest, most traditional windows on the market. Single hung windows feature two sashes, where the bottom sash is operable and moves up and down over the fixed top sash. On double hung windows both sashes move up and down and often tilt in as well.   

Pros and Cons of Single Hung and Double Hung Windows 

A few of the advantages of disadvantages of these window styles include:  


Single hung windows are often popular because of cost. They are more affordable than double hung windows, the difference in cost being anywhere from 10 to 20 percent. Installation costs on single hung windows are also cheaper. That might not seem like much when replacing a single window but can make a great difference when you think about replacing a dozen or so windows.   

Cleaning and Maintenance 

Single hung windows are not as easy to clean. The bottom sash might tilt in, but you will still need to access the upper sash from the outside. Double hung windows often feature a tilt in option on both sashes. This makes for easy cleaning and maintenance.   


Both window styles offer great ventilation, but double hung windows are slightly better. They open from the top and bottom. This means cool air can come in through the bottom while warm, humid air gets pushed out the top. This natural ventilation is great for generating more airflow, getting rid of humidity, and unwanted odor.   

A/C Friendly 

If you need window-mounted air conditioners, these window styles are an ideal choice. Because they slide up and down to open and close, they can safely house A/C units in place.   

Energy Efficiency 

The most efficient window styles are usually fixed windows with no breaks. Next would be casement windows because the entire pane locks against the frame when shut. Next would probably be single and double hung windows. Because of sash operation, these windows are not as air-tight. That said, modern advancements have made these windows more efficient than ever.   

Where can I Install Single and Double Hung Windows?  

These windows can work well in almost any room in the house. Homeowners commonly use these window styles in kitchens, living rooms, bedrooms, and even bathrooms. They also work well when flanking a larger picture window so you can get a great view, natural light, and some ventilation.

8 Tips to Get the Outside of Your Home Ready for Fall and Winter

window replacement in Oceanside, CA

  1. Repair Roof Leaks

Your roof protects your home. After spring and summer, you want to be sure there are no signs of leaks before winter. Check for signs of discoloration along the ceilings on the top floor or in the attic. If you do spot a leak reach out to a roofing company to repair it.   

  1. Clean the Gutters

The gutters and downspouts help direct water away from your home and the foundation. They need to be firmly attached to the house and clear of debris. If you notice anything the downspouts or clogged or a piece is missing, repair it right away.   

  1. Clean Outdoor Furniture

In Oceanside, CA you have a patio season that can extend well into fall and winter. If your outdoor furniture saw a lot of use in the summer, you might consider giving it a good scrub and maybe some fresh paint.

  1. Add Mulch to Flowerbeds

Adding extra mulch to the flowerbeds in fall has several benefits. It helps protect the soil and plants and provides some insulation in the colder months. It also reduces the growth of weeds.   

  1. Clear Debris from Outdoor A/C Unit

  1. ApplyWindow Caulking

Should I Worry about Condensation on my Windows?

San Diego, CA replacement windows

A common question we get from homeowners is about window condensation. While temporary condensation is normal, healthy even. There are some types of condensation to worry about that might indicate you need San Diego, CA replacement windows. Here is everything you need to know about condensation, when to worry, and what you might be able to do about it.   

Causes of Temporary Window Condensation 

There are several things that can cause window condensation including: 

  • High humidity from cooking or dishwashing 
  • Running the clothes washer or dryer 
  • Hot showers or baths 
  • The sudden drop in temperature outside 
  • The start of the heating season in the winter 
  • Fish tank or potted plants close to a window 

The Formation of Condensation 

You have probably noticed the mirror in the bathroom fog up after a steamy shower. Or seen a window in the kitchen cloud after cooking on the stove. Or noticed water condense on the outside of a cold drink on a hot day. The basics of these phenomena are the same. Warm air carries more moisture. But when the warm air comes in contact with a cold surface it cools and must release the moisture, causing condensation. This is why condensation is common, and not usually a major concern when it happens once in a while on your windows. It often dissipates on its own, no harm done.   

When is Condensation on My Windows a Concern?  

If you have a window in your home that is constantly fogging over this can be something to worry about. You don’t want water always dripping down the glass, into the frame, and seeping into the walls. It can cause rot, mold, and structural damage if enough moisture gets into the walls. You can increase ventilation and run exhaust fans in your home to limit humidity. Or you could invest in a dehumidifier to try and maintain proper humidity in your home.  

There is another type of window condensation you should worry about—fogging between the panes of glass. Have you ever gone to wipe away a smudge on a window only to discover you can’t? This means the seal on your insulated glass unit (IGU) is broken, the special gas has leaked out and been replaced with normal air that also contains moisture. So in addition to the condensation between the panes, you might also notice drafts or an increase in your energy bills. Unfortunately, the only way to really correct this problem is with energy efficient replacement windows.
