Two traditional window types, casement and sliding, merge into the practical and stylish sliding egress windows. These windows are necessary for safety and convenience in houses, especially those located on one level or in basements.
Each sliding egress window has unique characteristics that fulfill aesthetic and functional requirements. Below are the diverse types:
Horizontal Sliding Windows
One of the most widely used types of sliding egress windows is the horizontal sliding variety. These structures feature two or more sashes constructed to slide horizontally while remaining fixed in some portions. If opening space is restricted due to a property located near a fence or another home, horizontal sliding windows offer a sizable opening for safe egress. Since they stretch the full width of a wall, they serve as attractive solutions for basement and largeroom applications.
Vertical Sliding Windows (Sash Windows)
As classic sash windows, vertical sliding windows or sash windows are still in vogue. They comprise two sashes that slide vertically, with one sash fixed and the other functioning as an opening mechanism for egress. Vertical sliding windows are ideal for traditional homes that want to maintain a particular style. They effectively blend convenience with elegance. Beyond aesthetic values, they have an essential role in improving ventilation in upper floors.
Tilt and Slide Windows
A tilt-and-slide window performs two functions: the ability to tilt for ventilation and slide open for egress. Such flexibility is beneficial for homeowners who desire partial airflow without being fully opened. The problem arises when it is necessary to disengage and lock the window in a tilted position, which is not safe in the case of an emergency. When such windows are situated in locations where emergency egress is required, they must be fully opened.
Multi-Slide Egress Windows
Multi-slide egress windows, also known as patio doors, are designed with numerous sliding sashes. These windows can be pushed aside to create large openings, making them an excellent option for evacuation in emergencies. When it comes to aesthetics, multi-slide windows look great in modern homes and offer beautiful views. They serve practical functions during emergencies, such as allowing multiple people to vacate the building quickly.
Folding Sliding Windows (Bi-Fold Windows)
In contrast to multi-sliding window models, bifold egress windows consist of several sashes that fold and slide to one side. They are ideal for larger openings and can turn into beautiful entrances to gardens or patios. Due to their folding function, they require little space to operate, which is beneficial for restricted areas. They also provide excellent ventilation and natural lighting.
Sliding egress windows come in different types, each with specific features and maintenance needs.
Frame Materials
Sliding egress windows are manufactured in several frames, each with different pros and cons. Vinyl frames are maintenance-free and energy-efficient, making them ideal for basements. Wood frames provide a classic appearance and a high insulation value, but they demand periodic painting or staining. Aluminum frames are durable and require minimal maintenance yet have lower energy efficiency due to being conductive. In coastal areas, fiberglass frames are ideal as they resist corrosion.
Glass Options
Sliding egress windows offer glazing options that enhance energy efficiency and safety. Double glazing provides insulation by filling the space between the glasses with gas, usually argon or krypton, thus reducing heat transfer. Tempered glass is an impact-resistant glass that, when broken, shatters into small, rounded pieces, eliminating the risk of injury. Laminated glass consists of two glass panes that have interlayer plastic between them to increase security and reduce noise.
Tracks and Rollers
The smooth operation of sliding egress windows heavily depends on the tracks and rollers. Common track materials consist of stainless steel or aluminum, which are corrosion-resistant and ensure long-term function. Windows with larger sashes require heavy-duty rollers to ensure stability. Dirt accumulation on the tracks leads to window operation problems, necessitating periodic window cleaning.
Weather Stripping
Weather stripping is fixed around the window openings of sliding egress windows to guarantee an airtight seal. Common materials for weather stripping are silicone, vinyl, and foam, all having different lifespans and levels of efficiency. Over time, weather stripping deteriorates and requires replacement to prevent drafts, water seepage, and energy wastage. The window well covers should be regularly checked to ensure they are not damaged or obstructed by debris, compromising the function of the window.
Residential and commercial buildings use different situations to select sliding egress windows. Each situation needs windows that are effective, safe, and aesthetic. Below are several considerations based on application:
Residential Use
Sliding egress windows for residential areas should be attractive, effective, and safe. For homes in basements, egress windows must allow enough light and provide a view. Vinyl or wood frames are best suited for such applications. The glass must be double-glazed to improve energy insulation. The most common types of sliding egress windows for first-floor rooms are horizontal sliding and multi-sliding windows.
Commercial Use
For commercial buildings, sliding egress windows should meet different codes and standards. Bulk occupancy areas, like offices or hotels, need large egress windows to provide safe emergency exits. In this situation, multi-sliding or bifold windows are ideal because they create large openings. At this space, aluminum or fiberglass frames are durable and need little maintenance. The glass must be tempered or laminated for safety in high-traffic areas.
New Construction vs. Replacement
Another critical aspect to consider when picking egress windows is whether the project is new construction or replacement. Windows built into newly constructed houses provide ample design flexibility. Windows easily fit into existing structures in replacement projects, so the dimensions and style cannot be changed much. In replacement cases, existing window wells also have to accommodate new windows.
Coastal and High-Humidity Areas
In these regions, corrosion-resistant egress doors are vital. Fiberglass and stainless egress enclosure are ideal because they resist rust. Tempered and laminated glasses are also recommended, as they have the capacity to withstand wind pressure.
Energy Efficiency and Building Codes
Improving energy efficiency is one of the purposes of installing roof access hatches. New building codes demand more fenestration energy performance. One window type that fulfills energy efficiency is double-glazed glass. Ensure that the windows fulfill local regulations on egress, including size and minimum clearance requirements.
Sliding egress windows offer several advantages and disadvantages.
Space Efficiency
Sliding egress windows, unlike casement models, take up little space since they slide horizontally. They are ideal for areas with limited spaces, as the window only slides along the wall and does not extend outward.
Natural Light and Ventilation
These windows let much light into the room due to their large glass surfaces. In addition, opening the windows partially allows fresh air to enter without the need for full opening.
Emergency Exit
The passing size of sliding windows makes them suitable for emergency exits during fires and other emergencies. Occupants can easily exit through such windows, providing a safe escape path. They are ideal for basement bedrooms and living areas, fulfilling code requirements for natural light and ventilation while serving as emergency exits.
Security Features
Modern sliding egress windows come with advanced locking mechanisms and security bars, making it difficult for intruders to break into the house.
Maintenance Issues
A significant downside to sliding windows is the difficulty in keeping them. The large glass surface generally needs frequent cleaning to avoid dirt from collecting in the track, which makes the window hard to open or close. Windows with poor lubrication or maintenance risk making them difficult to open, affecting egress in case of an emergency. Homeowners should often clean the tracks and lubricate them to avoid sliding issues.
Limited Opening Options
Although these windows are ideal for emergency exits, they might not provide adequate ventilation when closed. Opening them fully is the only way to ensure enough airflow, which is not possible in some cases.
Installation Challenges
It may be hard to install sliding windows properly, especially in areas where the foundation shifts. If the installation is done incorrectly, the window will have issues sliding, making it hard to use as an emergency exit.
A1: To serve adequately, a sliding egress window should be at least 3 feet wide and 2.5 feet tall. This regulation allows occupants to exit safely and emergency workers to enter with ease.
A2: Vinyl is the most ideal material for basement sliding egress windows. It is resistant to moisture and doesn't require much maintenance compared to wood or aluminum frames.
A3: Tempered glass is vital because it breaks into small, rounded pieces rather than sharp shards. This feature minimizes the risk of injury. In situations with extreme heat, such as a fire, tempered glass is more resistant to breaking.
A4: Yes, there are many options available. Double-glazed glass filled with argon gas offers increase insulation. Coating the glass with low-E reduces heat making it ideal for warm climates.
A5: Slides-in windows require cleaning of tracks and sashes. Use a silicone-based lubricant on the tracks to prevent sliding issues. Regularly inspect weather stripping for damage and replace it as needed.
