Tigerflex Shiplap Pent Double Door Shed – Expert Review

This review covers the TigerFlex Shiplap Pent Double Door Shed, specifically the windowed version.

It’s important to be upfront about how this assessment is formed, because that honesty is central to how we review sheds.

We have physically inspected the non-windowed version of this shed at the Otley show site. Everything we say about build quality, structure, rigidity, floor strength, wall stiffness, framing, and overall feel comes directly from that hands-on inspection and testing.

What we haven’t done is physically inspect this exact windowed configuration at a show site. However, the only material difference between the two is the inclusion of windows. The structure, materials, framing, floor, roof, doors, and modular system are the same — and we’ve reviewed enough TigerFlex windowed sheds elsewhere to be very comfortable explaining how that changes (and doesn’t change) the experience.

So this is not speculation. It’s a transparent extension of first-hand inspection, clearly stating where direct observation ends and informed judgement begins.

Why the TigerFlex pent sheds continue to impress us

One thing we’ve consistently liked about the TigerFlex range is that it doesn’t just offer variations for the sake of marketing — the modularity genuinely changes how usable the shed can be in real gardens.

The pent roof plays a big role in that. Because it slopes in one direction, it naturally lends itself to:

• Being positioned under overhangs
• Sitting close to fences or boundaries
• Working well in tighter or more awkward spaces
• Keeping overall height down where that matters

That alone makes pent sheds very practical. But where TigerFlex really differentiates itself is by combining that roof design with a fully modular panel system.

Window flexibility: the real strength of this version

The biggest advantage of the windowed double door version over the non-windowed one is flexibility — and not in a vague, brochure-friendly way, but in a genuinely practical sense.

Because of the TigerFlex modular design:

• You can position the windows on either side
• You can put windows at the ends
• You can place a window in a corner panel
• You can move the door to suit access, not aesthetics

If you want:

• A light, airy workspace, you can do that
• A more private, enclosed setup, you can do that too

That level of choice is rare. Most sheds decide the layout for you. TigerFlex lets you decide — and that’s especially useful if your garden layout is a bit quirky or doesn’t suit a “standard” shed orientation.

This is exactly why we often say the TigerFlex range works best for people with slightly unusual requirements. It adapts to the garden, rather than forcing the garden to adapt to it.

Double doors: genuinely usable space

One of the things that really stood out when we inspected the non-windowed double door version at Otley was just how much access the double doors give you.

This isn’t a token widening — it’s a proper, usable opening.

You have:

• Plenty of clearance for bulky equipment
• Easy access for wheeled items
• No awkward twisting or lifting

In real terms, you can comfortably get a motorbike into this shed. In fact, we know people who have bought this exact shed footprint and used it for motorbike storage. Some opted for the security version, which we’ve also reviewed, but the underlying point remains: the access is genuinely generous.

For garden equipment, workshop use, or anything you regularly move in and out, the double doors are a real quality-of-life improvement.

Windows vs no windows: a more nuanced view of security

A lot of buyers automatically assume “no windows = more secure”. That’s sometimes true — but not always.

If you’re storing valuable items, the security version makes sense. But if you’re mainly storing basic garden equipment, tools, or general gear, windows can actually act as a deterrent rather than a risk.

Here’s why.

The windows on the TigerFlex sheds use 3mm toughened glass. They’re well made, properly framed, and not oversized. If someone wanted to break in through a window:

• They’d have to make a loud, unmistakable noise
• They’d be very visible doing it
• And they’d immediately see whether there’s anything worth stealing

In many cases, it’s better for someone to see there’s nothing worth stealing than to let them imagine what might be inside.

We’ve seen plenty of cheaper sheds that use:

• Thin styrene glazing that yellows over time
• Plastic windows that flex
• Vacuum-formed panels that can literally be pushed out

We’ve even inspected a cheap shed where leaning on the window could pop the entire unit out of the frame — genuinely shocking.

This is not that.

The toughened glass here is solid, durable, and if something ever does happen, it’s easy to replace. It’s a sensible, well-executed solution rather than a cost-cutting one.

Timber quality: where paper specs stop telling the story

On paper, a lot of sheds claim 12mm tongue and groove cladding. In reality, that figure alone tells you very little.

What matters is:

• Timber grade
• Growth rate of the wood
• How well it’s planed
• How consistently it’s machined

The shiplap tongue and groove used here is noticeably higher quality than what you see on many competing sheds. It’s made from slow-grown timber, properly planed, and cleanly finished.

We’ve stood sheds side-by-side where both claim “12mm T&G”, and the difference in timber quality is night and day. Rough, splintery boards on one; smooth, precise boards on the other.

That’s the difference good materials make. If you start with quality ingredients, you end up with a quality product — and that’s exactly what’s happening here.

Floor and wall strength: tested, not assumed

When we inspected the non-windowed version at Otley, we didn’t just look at it — we tested it.

• A 75kg floor load test resulted in around 2mm of deflection
• A 75kg wall load test (leaning into the wall from inside) produced about 3mm of movement

Those are excellent results and point to a very stiff, well-braced structure.

A lot of that comes down to how the modular panels lock together. When correctly assembled, the joins themselves add strength, not weakness. The panels brace each other, increasing rigidity across the whole footprint.

That’s why we stress proper assembly. If this shed is built square, level, and with care, it becomes very, very solid.

There’s no reason to expect the windowed version to behave any differently structurally — the framing and floor system remain the same.

Windows: the only assembly note worth mentioning

If there’s one small assembly detail worth being aware of, it’s the window installation.

TigerFlex windows are fitted using:

• A bead of silicone sealant
• The glass pane seated into place
• A small nail to tack the glazing bead

This is standard practice across many quality timber sheds, but we’ve always been slightly uncomfortable in principlewith nails being involved — even though, in practice, it’s not an issue if done correctly.

If you:

• Use galvanised or steel nails
• Seal properly
• Fit carefully

…there’s no longevity problem here.

And again, compared to the plastic or vacuum-formed alternatives we’ve seen elsewhere, this is still a far superior solution.

What this shed is best suited for

The TigerFlex Shiplap Pent Double Door Shed (windowed) is particularly well suited to:

• A light-filled workshop
• General garden storage
• Equipment that benefits from visibility and airflow
• Buyers who want layout flexibility
• Anyone needing wide, practical access

It sits perfectly in the overlap between shed and workshop, without pretending to be something it isn’t.

Sizes and options (brochure context)

According to the Tiger brochure, this shed is available in a broad range of sizes, typically including:

• 4’ x 4’
• 4’ x 6’
• 8’ x 4’
• 8’ x 6’
• 10’ x 6’
• 12’ x 6’

Combined with the modular door and window placement, that gives you an unusual amount of control over how the shed actually works in your space.

Final verdict

The TigerFlex Shiplap Pent Double Door Shed is a genuinely versatile, well-made building.

Because we’ve physically inspected the non-windowed version, we’re confident in the underlying structure, materials, and rigidity. The windowed version builds on that foundation by adding light, flexibility, and usability — without undermining quality.

If you need wide access, want a bright internal space, and value the ability to tailor layout to your garden rather than compromise around it, this is a very strong option.

It’s not flashy. It’s not gimmicky. It’s just well thought out, well made, and extremely adaptable — which, in practice, is exactly what most people actually need.
