Windows are often the most vulnerable element of a house, especially if they are worn out and are easy to pry upon.

This article will throw light on some of the essential aspects of double hung window locks. We shall discuss a few types of window locks, critical factors to consider while buying a window lock for your double-hung window, and a detailed review of some of the best security locks. Before we come to the point, let us first discuss the need for a window lock for your home.

Who Should Invest in a Window Lock?

Different people have different reasons for needing a lock for their double-hung windows. The reason will influence your decision about which lock to purchase. I am listing below a few reasons you may need to buy window locks for your double-hung windows.

• You are concerned about the safety and security of your house while you are away from home.
• The pre-installed locks of your windows are not that strong. Hence, you need another layer of security.
• You have children at home, and hence, you need to childproof your double-hung window for their safety.
• You are looking for a window lock replacement as your existing locks are worn out.

Single-Hung Windows v/s Double-Hung Windows

Both single-hung windows and double-hung windows have an upper sash and a lower sash that separates the window. If you see from a distance, the two window styles look exactly the same. In a single-hung window, The bottom panel, or the sash, moves vertically, but the upper sash remains stationary. However, in a double-hung window, both the sashes are functional. Cost-wise, single-hung windows are less costly than double-hung windows and hence are more common in new houses and apartments. Functionally, double-hung windows allow more efficient ventilation as compared to single-hung windows and are easier to clean. 

Types Of Double Hung Window Locks

While I consider hinged wedge locks as the most secure locks for double-hung windows, there are a few types of window locks for double hung windows available in the market. Let us discuss these types one by one.

Latch Lock

Latch locks are the most common type of locks that work on a simple mechanism of holding the sashes in place. They are often the standard pre-installed locks found on most single-hung and double-hung windows. These locks work on a simple mechanism of connecting the two sashes together and preventing them from moving. While latches hold the sashes in place, these locks are not the strongest for a window and should not be the only lock on your double-hung window.

Keyed Locks

Keyed locks are the most conventional type of locks. Keyed locks are more robust in terms of security as compared to latch locks. Hence, these locks are frequently paired with latch locks to keep windows secure. Keyed locks, in my opinion, have only one downside, i.e., keeping track of the key. If you do not have trouble handling the keys, these locks are great for you.

Pin Locks

Pin locks for windows are similar to chain locks on windows. The working mechanism of these locks involves one part of the lock attaching to the sash, and the other to the frame. The chain prevents the window from opening by dropping a pin into the window frame hole. These locks are easy to install and are high on the security part.

Hinged Wedge Locks

Hinged wedge locks are great double hung window security locks as these locks lock both the panels of the double-hung window. If a hinged wedge lock is installed directly above the sash, it keeps a closed window from opening until you push the window lock inward. If the lock is placed higher on the window frame, you can open the window partially but not completely until the lock is pushed inward.

What To Look For While Buying The Best Double Hung Window Locks?

Installing window locks is a long time investment. Once installed, the lock continues to secure your windows for years. Hence, it is vital to consider a few factors while buying the best lock for your double-hung window.

• Size Of The Window: The lock that you will buy for your window depends mainly upon the size of the window. The majority of the people want their window locks to blend with the surroundings. A standard window is sized somewhere around 48 inches X 60 inches. However, AC windows are more diminutive. Hence, knowing the size of your window will affect your decision of which lock to buy. Also, the track height and track thickness of the window is a point to be considered. Most tracks are about 1.5-2 cm high and 1.5-1.8 cm thick. So, looking for a lock that fits is crucial.

• Budget: Window locks are available in varied budget options based upon their brand, material, level of security, etc. An excellent double-hung window lock will cost you somewhere between $8-20, depending on its type and features.
  
• The Level Of Security: Whether you need a lock to childproof your home, to keep the burglars at bay,  for ventilation purposes, or as an added layer of security when you are away, the lock that you will buy for your double-hung windows depends upon the level of protection that you need. While some locks offer high-grade protection, some are not as secure to prevent thieves from prying.

• Material Of The Lock:  Locks are available in various materials like plastic, steel, aluminum, etc. If you are looking for a lock that is high on security, you should look at a sturdy metal or alloy lock. If you are pet-proofing or childproofing your home, plastic locks work fine and are affordable. Also, if you live in a moist place, buying an anti-rust lock is a requisite.

• Ease of Installation: The installation process of locks varies greatly. Some locks can be easily installed, while some need professional help to install them. The ease of installation that you prefer will help you select the lock for you. There are locks available that do not require any drill or screw to install. So, if you avoid making any structural changes to your window, these locks may suit you the best.

• Suitability: Not all locks can be installed on a double-hung window. Keeping the filter on while choosing the one for you is essential. Many users end up buying a lock that is not compatible with their windows. However, most locks are returnable if bought through amazon.com; still, why mess up?

However, the lock is not childproof, which I consider an important feature to consider if you have toddlers or kids at home.

FAQs

Q1. I  already have locks pre-installed on my apartment’s double-hung windows; should I still add another layer of security to them?

Answer –  Pre-installed locks are often latched locks that are not so high on security. While these locks will work well if you want to close the window to prevent dust or cold, I do not rate them as great security devices. Adding another layer of security to your window will protect your house from theft.

Q2. Do plastic peel and stick locks strong enough to prevent children from opening the lock?

Answer – The plastic peel and stick locks are strong enough to prevent your toddlers from venturing into the area you don’t want them to. For kids above the age of 6, these locks may not be suitable. More childproof locks are available in the market, which offers better security to your window. Read some of my recommendations in the article.

Answer – In a single-hung window, one window sash moves, and the other remains stationary. However, in a double-hung window, both the window sashes move. While single-hung windows are more cost-efficient, double-hung windows offer better ventilation and are easy to clean.
