Impact Resistant Glass for Storm and Wind Protection

t445-33

Impact resistant glass is laminated glass designed to hold together when struck by debris or pressure from strong winds, reducing the risk of shattering and openings in the building envelope. For homes that face severe weather, it works best when the glass is set correctly in a sound, well-anchored frame such as a Belgian steel-look profile window or door. Always confirm the glass specification and installation details with your engineer before ordering.

What Makes Glass Impact Resistant

Impact resistant glass is usually laminated glass. Two or more glass layers are bonded together with a strong interlayer, most often PVB or a similar material. When the glass is struck by flying debris, the layers tend to crack but stay bonded to the interlayer instead of breaking into loose shards.

The thickness, number of layers and interlayer type all affect how the glass performs. Ask for the specification in writing so you know exactly what has been supplied and where it is installed.

Why the Frame Matters as Much as the Glass

Glass only performs as well as the frame holding it. A weak frame can flex, twist or pull away under wind pressure, and the glass can fail even if the pane itself is strong.

Solid profiles with reinforced corners
Secure glazing beads and sealing
Anchors fixed properly into the wall structure

Steel-look profile windows and doors offer a rigid frame with a slim sightline, which suits both appearance and structural needs.

Preparing Your Home for Severe Weather

Good preparation starts before the storm season. Walk around your home and look at the openings most exposed to wind, especially on upper floors and facades facing the prevailing weather direction.

Quick checks

Look for cracks, loose glazing or failing seals
Test that locks and handles close firmly
Check that drainage around frames is clear

Address any issues early, since repairs are easier to plan on a calm day.

Standards and Safety Considerations

Railings, balconies and glazed elements in Israel are expected to meet the relevant standards, including the Israeli railing standard SI 1142 for guarding and safety. Standards set minimum requirements, and the exact values for loads, heights and glass types depend on your building and location.

Because these values are specific to each project, the right approach is to have your engineer confirm the design. We can help prepare the drawings and specification so the requirements are clear from the start.

Choosing the Right Glazing for Your Project

Not every opening needs the same level of protection. Ground-floor openings, balconies and areas with large glass panels usually deserve closer attention than small windows set high in a wall.

Measure the opening and note its exposure
Discuss glass type and thickness with your installer
Request a written specification and drawing

A site visit allows us to measure accurately and advise on the most suitable option for your home.

From Inquiry to Installation

Our process is straightforward. You send photos of the openings, we arrange an on-site measurement, and we prepare a drawing and written specification for your approval. Once approved, the windows or doors are manufactured to measure at our Tel Aviv factory on Rival Street 37.

Finishing such as hot-dip galvanizing or powder coating is applied before installation, so the frames are prepared for long-term exposure. Installation is carried out with careful attention to anchoring and sealing.

Frequently asked questions

Is impact resistant glass the same as unbreakable glass?

No. Impact resistant glass is designed to resist breakage and hold together when struck, but no glass is completely unbreakable. It reduces risk rather than eliminating it.

Does the window frame affect storm protection?

Yes. A rigid, well-anchored frame keeps the glass secure under wind pressure, so frame quality matters as much as the glass itself.

Do I need an engineer to approve the glass?

For most projects, it is wise to have your engineer confirm the glass type, thickness and installation details against the applicable standards.

Can I upgrade existing windows to impact resistant glass?

It is often possible, but the existing frame must be strong enough to carry the new glass. A site measurement and inspection will show whether an upgrade or a new frame is the better option.

Common mistakes to avoid

Many homeowners focus only on the glass and overlook weak frames, loose glazing or poor anchoring. Ordering glass without a written specification can also lead to mismatched products.

Our recommendation

Inspect your frames and seals before storm season, and request a written specification that names the glass type and installation method. Have your engineer confirm the details before production begins.

Summary

Impact resistant glass works best when paired with a strong, properly anchored frame and a clear written specification. Checking your openings early gives you the most protection when severe weather arrives.
