2026 Guide to More Secure Doors and Windows for Colorado Homes

You want two things this year: a safer home and fewer drafts. 

Colorado’s brutal cold fronts make weak locks and leaky frames show fast, so simple changes pay off right away.

The fastest upgrades are more secure locks and better glass to make doors harder to force, help cut chilly air leaks, and still keep the look you love. 

Your quick picks for a secure home

• Multi-point lock: Secures the door at the top, middle, and bottom for a tighter seal and better resistance to prying.
• Privacy glass: Lets natural light in while blurring the view from outside.
• Laminated glass: Two panes bonded with a clear interlayer that stays intact if cracked for added impact resistance.
• Hook locks: Curved latches that grab into the frame and resist prying better than straight latches.
• Footbolt: A toe-operated secondary lock at the base of the sliding panel for quick, added security.

Why this matters in Colorado

Colorado’s fast-moving fronts and big day–night swings can flex doors and windows. When panels shift, tiny gaps open, drafts creep in, and single-point latches take all the stress. Bright winter sun adds glare and fades furnishings.

What you’ll notice with the right upgrades

• Security: Panels stay aligned under wind and pressure, so pry attempts have less leverage.
• Comfort: Fewer cold spots and drafts near doors and windows, steadier room temps.
• Privacy & light: Daylight without street views; less glare on bright winter days.
• Wear & tear: Hardware and seals last longer because the load is spread and the panel stays tight.

Entry doors: Features to ask your installer for

When choosing a new entry door, these features can make a noticeable difference in security and durability. Here’s what to ask about and where each upgrade applies:

• Multi-point locking system: Ask if the lock secures the door at the top, middle, and bottom of the frame, not just at the handle. These locks are built into the door edge and help keep the entire door panel tight and harder to pry open.
• Privacy or decorative glass: If your door has glass that faces the street, ask about privacy or textured glass options. These are installed in the door panel itself and allow light in while limiting visibility from outside.
• Laminated glass: For added break-in resistance, ask whether the glass insert is laminated. Laminated glass is used in the door’s glass section and includes a clear interlayer that holds the pane together if it cracks.
• Reinforced strike plate and hardware: Ask if the strike plate is reinforced and secured into the framing with 3-inch screws. This hardware sits on the door frame where the lock engages and plays a major role in preventing forced entry.
• Heavy-duty hinges with security pins: Hinges are located along the side of the door opposite the lock. Ask for heavy-duty hinges, and if the hinges are exposed on the exterior, confirm that security pins are included to prevent the door from being removed.

Easy brand picks

• Provia Ascent™ fiberglass entry door (new for 2026): realistic White Oak or Smooth skins with a tough, low-upkeep shell.
• Fluted privacy glass (new for 2026): lets daylight in while blocking street views.
• 6-9/16" PermaTech™ frame (new for 2026): deeper, sturdier frame for a cleaner, longer-lasting install.

Patio doors: Features to ask your installer for

Patio doors are a common weak point because of their size and frequent use. The right locking features can significantly improve security and long-term performance.

If you have a sliding patio door

• Hook-style locking system – Ask for hook locks instead of a standard straight latch. These curved hooks engage into the frame and resist prying much better. Two hooks are common, and some models offer four-hook systems for added strength.
• Foot lock at the sill – Ask if a toe-operated foot lock is available for your door. Installed at the bottom of the sliding panel, it provides a quick secondary lock without needing a key.

If you have French patio doors

• Multi-point locking system: Ask whether the active door locks at multiple points along the frame, not just at the handle.
• Deadbolt option: Confirm that a deadbolt is included and ask how many locking points engage when the door is secured.

Easy brand picks

• Anlin Malibu uses dual hook latches, with a four-hook Quad-Lock upgrade. Hooks grab into the frame and resist prying far better than a straight latch.
• Anlin is offering a footbolt for patio doors (brand-specific add-on). It’s a toe-set secondary lock at the sill for quick extra security; ask about availability on your Malibu configuration.
• Optional 3/8" stainless deadbolt + heavy-duty rollers/track. Add a solid deadbolt for a simple second lock, and get long-life glide from sealed-bearing rollers on a one-piece stainless track.

Home windows: Features to ask your installer for

Colorado’s wide temperature swings, strong sun, and winter cold make window performance especially important. These features help improve security, comfort, and efficiency.

• Laminated glass for added security: Ask about laminated glass for first-floor and street-facing windows. It’s built into the window pane and cracks without shattering, staying together longer during impact.
• Tight fit and locking hardware: Ask how the locks pull the sash tightly into the frame. Closed windows should feel solid with no wobble or air movement.
• Comfort-focused glass package: Choose double- or triple-pane glass with Low-E coatings, argon fill, and a warm-edge spacer to reduce drafts and heat loss.
• Energy ratings for Colorado homes: Ask to see the NFRC label and target a U-factor of 0.22 or lower and an SHGC of 0.17 or higher.

Easy brand picks 

If you want a tougher, more secure window upgrade for 2026, start with these Anlin Del Mar highlights:

• Anlin Del Mar adds First Guard laminated security glass. It’s two panes bonded around a clear layer, so if hit it cracks but stays together (harder to push through, noisier).
• Locks anchor into reinforced framing. Anlin’s lock hardware mounts into fiberglass reinforcement and an interlocking rail helps stop “jimmying,” so latches keep holding tight over time.
• Optional stainless sash deadbolt on sliders. A simple extra lock you can set for peace of mind on sliding windows.

What to ask at your window and door estimate

1. Multi-point lock & hardware: Which multi-point lock will you install, and will you add a reinforced strike with 3-inch screws and heavy-duty hinges (with security pins if hinges are exposed)?
2. Patio door hold & anti-lift: How many hook locks can my slider have, is a footbolt available, and will you include anti-lift blocks (and a deadbolt, if the model supports it)?
3. Stronger glass where it counts: Can I get laminated glass on first-floor and street-facing openings, and can my chosen privacy/decorative glass be ordered in a laminated version?
4. Frames, rollers, and wear parts: How are the locks anchored into the frame, what are the roller/track materials on the patio door (stainless preferred), and what’s the warranty against warping/sagging and hardware failure?
5. Install for long life: Will you use a sill pan, flashing tape, and low-expansion foam and do a final draft check/adjustment before leaving? Also, who do I call for service, and for how long is labor covered?

Door & window installation: What to confirm with your installer

1) Before you sign (quick checklist)

• Who’s doing the work – Confirm the company is licensed and insured, whether the installers are in-house or subcontracted, and that they’re certified for the brand being installed.
• Exactly what you’re getting – Make sure the quote lists the exact product models, colors, and door swing, plus where security features like multi-point locks, hook locks, footbolts, and laminated glass will be used.
• Comfort and energy performance – For Colorado homes, ask for the target U-factor and SHGC and confirm they’ll show you the NFRC label for the exact windows or doors you’re buying.
• How the installation will be done – Ask about sill pans, flashing, sealing, and insulation methods, and confirm that floors, landscaping, and debris cleanup are included.
• Timeline and protection – Get clear expectations for lead time, how long installation will take, what warranties are included (product and labor), and who to contact if you need service later.

2) Before they leave (final walk-through)

• Open, close, and lock everything – Make sure doors and windows move smoothly and all locks fully engage.
• Check for drafts – Run your hand around the frames and have any air leaks sealed before the crew leaves.
• Look at the fit – Gaps should be even, locks should line up properly, and rollers or strikes adjusted if needed.
• Confirm labels and glass – Take photos of NFRC labels and verify which windows or doors include laminated glass.
• Inspect seals and drainage – Caulk lines should be clean and continuous, and drain holes clear.
• Get the basics explained – Have the installer show you how to use the locks or footbolt and how to clean and maintain the products.
• Collect your paperwork – Get your receipt, warranty details, product list, and a clear service contact.

FAQs

How do I make sure my windows are secure?
Start by locking them every time. Good locks should pull the sash tight to the frame. Add simple upgrades where they matter most:

• Use laminated glass on ground-floor and street-facing windows.
• Add a pin lock or track stop on sliders so they cannot be forced open.
• Install anti-lift blocks so a slider cannot be lifted out of the track.
• Make sure the frame is sealed and the sash closes without wobbling. If your windiest walls feel drafty, consider casement or awning styles that press into a tight seal when locked.

Are doors with windows secure?
They can be. Choose laminated glass for the window in the door so it stays together if cracked, and use a multi-point lock so the door grabs the frame at the top, middle, and bottom. Add a reinforced strike plate with 3-inch screws and pick a privacy or decorative glass style if your door faces the street.

Can burglars open a locked window?
A weak latch or loose frame can be pried. Sliding windows and doors are also vulnerable if they can be lifted out of the track. Make it harder by keeping windows fully closed and locked, adding a pin or dowel in the track, installing anti-lift blocks, and using laminated glass where it counts.

What are the most burglar-resistant windows?
No window is 100% break-proof, but some setups are tougher:

• Picture (fixed) windows are the tightest because they do not open.
• Casement or awning windows use a compression seal and are typically harder to pry than basic sliders.
• Laminated glass adds real resistance to forced entry.
• Sturdy frames (fiberglass, composite, quality vinyl) keep seals tight so the locks bite well. 

Use fixed windows where you do not need to open them, and pair with an operable unit nearby for ventilation and egress.

How do I make sure my home doors are secure?
For entry doors, choose a multi-point lock, a reinforced strike, and laminated or privacy glass if there is a window in the door. Use heavy-duty hinges and, if hinges are exposed, ask for security pins.For sliding patio doors, choose hook latches (2 or 4 hooks) and add a foot-lock at the sill if available. Keep the rollers adjusted so the panel closes smoothly and tight. For French patio doors, look for multi-point locking plus a deadbolt, and confirm the inactive panel locks into the head and sill.
