What makes a greenhouse hurricane-proof in Ireland?

In October 2017, Ireland was battered by Hurricane Ophelia - the worst storm to hit Irish shores in 50 years, with winds reaching up to 115mph.

It was the ultimate test for Landmark Greenhouses, and we're proud to say we passed it. As the storm raged, we held our breath right alongside our customers. But the results spoke for themselves - and the messages we received afterwards filled us with pride.

One delighted customer wrote to us: "Landmark 1 - Ophelia 0"

Another shared: "Our Landmark Greenhouse is staring out at Ophelia saying: come get me."

The best part? Every single one of our greenhouses held firm against those punishing winds.

With our exciting new Greenhouses for 2026 range just around the corner – featuring enhanced storm protection features – we thought this would be the perfect time to revisit one of our most popular topics: why Landmark Greenhouses can stand up to even the most challenging weather conditions.

Why Landmark Greenhouses Are Hurricane Proof: Built to Weather Any Irish Storm

The secret lies in careful engineering and premium materials. While many greenhouse manufacturers cut corners with lightweight materials, ours has taken a completely different approach.

Landmark Greenhouses are constructed with heavy-duty aluminium frames and toughened glass that's securely fastened with high-quality rubber beading. This makes them significantly heavier and more stable than cheap aluminum alternatives you might find elsewhere. When anchored into a solid concrete foundation, that extra weight and robust construction makes all the difference.

Introducing Our New Storm Support System

This year, we're taking hurricane protection even further with our brand-new storm support system. These innovative cross beams can be quickly installed inside your greenhouse when severe weather is forecast, providing an extra layer of structural support exactly when you need it most.

When a hurricane is forecast, install these extra cross beam supports for extra durability.

Combined with our standard storm preparation recommendations – closing and locking all roof vents and doors to create an airtight seal, and ensuring your greenhouse is properly anchored to solid foundations – these new storm supports give you even greater peace of mind.

One advantage of our built-in staging shelves is that you won't need to clear out your greenhouse shelves before a storm. Our staging actually adds beneficial bulk and stability to the structure.

Ready for Whatever Weather Comes Next

At Landmark, we don't just build greenhouses for perfect sunny days. We build them for the reality of changing weather patterns and increasingly severe storms. When you invest in a Landmark Greenhouse, you're investing in engineering that's proven itself against some of the worst weather nature can throw at it.

Whether you're considering one of our established models or waiting for our exciting 2026 range, you can have confidence that your greenhouse will be there for you, season after season, storm after storm.
