The windows considered the most difficult to break into are those that combine high-performance fiberglass frames with laminated security glazing. This specific glass type uses two layers of glass bonded by a Polyvinyl Butyral (PVB) or ionoplast interlayer, which keeps the shards intact when struck and resists penetration from smash-and-grab attempts.

To maximize the security of your window assembly, we recommend the following components:

• Impact-Resistant Glass: Laminated options offer superior protection compared to tempered glass, which shatters into small fragments and provides little resistance against forced entry.
• Security Film: Applying a polyester film with a minimum thickness of 8 mil creates an invisible web that significantly delays forced-entry attempts.
• Reinforced Hardware: Substituting standard manufacturer screws with 3-inch heavy-duty fasteners allows the window to bite directly into the structural framework of the house, substantially increasing shear strength.
• Secondary Locks: Mechanical upgrades such as sash jammers or keyed secondary bolts prevent a sash from being tilted or slid open even if the primary latch is compromised.

We utilize Design Build Services to ensure these windows are installed as structural components rather than mere trim pieces. Please note that estimates are preliminary and subject to change after a site inspection, and permit requirements vary by jurisdiction. Let us help you get your project started by evaluating your home’s specific security needs.
