Technical Specifications of an Ipé Slatted Fence

Mechanical performance of Ipé hardwood

Beyond its exceptional natural durability, Ipé is renowned for its outstanding mechanical performance. The combination of extreme density, a powerful fibre structure and very limited movement makes this hardwood ideal for structures that must withstand continuous outdoor exposure. This is why Ipé is used worldwide not only for premium fencing, but also for bridges, boardwalks, heavy-duty decking and architectural landscaping.

For fencing, this means greater resistance to wind loads, impact and changing weather conditions. Even through large fluctuations in temperature and humidity, the construction remains remarkably stable. Modern slatted fences therefore retain their clean lines and premium appearance for many years.

Technical performance in practice

Why these properties matter in premium fencing

A fence is constantly exposed to wind, rain, sunlight, temperature changes and natural timber movement. Softer timber species often react more dramatically, causing boards to distort, joints to open or fixings to come under stress.

Thanks to its exceptional mechanical strength, Ipé remains far more stable under these conditions. This also allows our concealed fixing systems to perform exactly as intended, maintaining consistent spacing between the slats. The result is not only a cleaner architectural finish, but also a significantly longer lifespan for the complete fence system.

Timber movement and dimensional stability

Every timber species naturally responds to changes in temperature and humidity. During wet weather timber absorbs moisture and expands slightly, while in dry periods it releases moisture and contracts. This natural movement can never be eliminated completely. However, there are major differences between timber species, and this is exactly where Ipé excels.

Its exceptionally dense cellular structure absorbs far less moisture than most hardwoods. As a result, the timber remains remarkably stable even during changing weather conditions. This is one of the key reasons why Ipé is specified worldwide for premium fencing, luxury decking and architectural cladding where straight lines and consistent spacing are essential.

Why dimensional stability matters in modern fencing

Contemporary slatted fencing relies on precise tolerances throughout the entire construction. If timber moves excessively, joints become uneven, concealed clips come under stress and slats may begin to twist or distort. Thanks to the outstanding dimensional stability of Ipé, spacing remains consistent and the fence retains its clean architectural appearance for many years.

Designed for the British climate

The UK climate brings frequent rainfall, high humidity, occasional frost and regular temperature changes throughout the year. Under these conditions, Ipé demonstrates why it is considered one of the world's premium hardwoods. Its exceptional density, natural durability and minimal movement ensure that fences remain straight and stable while requiring very little maintenance. Applying a quality hardwood oil periodically helps retain the original colour, reduces moisture loss and minimises the chance of surface checking.

For modern slatted fencing this is particularly valuable. Perfectly aligned slats, consistent gaps and concealed fixings continue to perform exactly as intended, allowing the fence to retain both its technical performance and luxurious appearance for many years.

Why stainless steel fixings are essential for Ipé

The lifespan of a premium Ipé fence depends not only on the timber itself, but also on the correct fixing system. Ipé naturally contains tannins that contribute to its exceptional durability. However, these same natural compounds can react with galvanised or untreated metals, causing corrosion, rust and dark staining on the timber surface.

For this reason, we exclusively recommend high-quality stainless steel fixings. Stainless steel protects both the timber and the fasteners, ensuring that your fence remains structurally sound and visually perfect for decades.

Why galvanised screws should be avoided

Galvanised screws are suitable for many timber species, but Ipé requires a higher specification. Moisture combined with the timber's natural tannins can gradually attack the zinc coating, leading to corrosion and dark discolouration around the fixing points.

Professional Ipé fencing systems are therefore almost always installed using stainless steel screws or concealed stainless steel clips. This eliminates corrosion risks while preserving the clean architectural appearance of the fence.

Concealed fixing systems for architectural fencing

Modern slatted fencing is increasingly installed using concealed fixing systems. The screws remain completely hidden, leaving only the clean horizontal or vertical lines of the hardwood visible. This minimalist appearance perfectly complements contemporary architecture and luxury garden design.

Besides their visual appeal, concealed stainless steel fixings distribute structural loads evenly across the fence. This reduces stress within the timber, helps maintain dimensional stability and contributes to the exceptionally long lifespan of the complete fencing system.

Proper construction and ventilation maximise the lifespan of an Ipé fence

Even the world's finest hardwood will only achieve its full lifespan when installed correctly. A premium Ipé fence depends not only on exceptional timber quality, but also on good ventilation, efficient drainage, high-quality fixings and a solid structural framework. A well-designed construction prevents moisture from remaining trapped, allowing the timber to dry naturally after rainfall and ensuring outstanding long-term performance.

Although Ipé is naturally one of the most moisture-resistant hardwoods available, proper airflow remains essential. Adequate spacing between the slats and behind the fence encourages continuous ventilation, helping the timber dry quickly after rain while further enhancing its natural durability. This also contributes to the excellent dimensional stability for which Ipé is renowned.

Key construction principles

Designed to withstand the British climate

The UK experiences frequent rainfall, strong winds, changing temperatures and periods of high humidity throughout the year. These conditions place significant demands on outdoor timber. Thanks to its exceptional density and mechanical strength, Ipé remains remarkably stable even under prolonged exposure to the elements, making it one of the finest hardwoods available for premium fencing.

Combined with hardwood posts, concealed stainless steel clips and professional installation, an Ipé fencing system delivers exceptional long-term performance while maintaining its premium appearance for decades.

Why professional installation makes all the difference

A luxury fence is about much more than selecting premium timber. Accurate post spacing, correct ventilation, perfectly aligned slats and high-quality concealed fixings all contribute to the overall performance of the system. Modern slatted fencing is increasingly designed as a complete engineered solution, with every component working together to maximise strength, appearance and longevity.

Why we specialise exclusively in Ipé hardwood

Many timber suppliers offer a wide variety of hardwood species, including Cumaru, Bangkirai, Garapa and Massaranduba. Each has its own characteristics, but after years of experience we deliberately chose to specialise in only one species: Ipé hardwood. The reason is simple — no other hardwood combines exceptional structural performance, outstanding dimensional stability and timeless beauty quite like Ipé.

Modern fencing demands straight lines, minimal maintenance and decades of reliable performance. Thanks to its remarkable density, minimal movement and Durability Class 1 rating, Ipé consistently delivers one of the highest quality fencing solutions available anywhere in the world.

Where is Ipé hardwood used around the world?

The outstanding engineering characteristics of Ipé make it suitable for far more than premium fencing. Thanks to its exceptional density, remarkable structural strength and natural durability, Ipé is specified worldwide wherever outdoor structures must perform reliably for decades.

Architects, landscape designers and engineers regularly choose Ipé for projects where durability, dimensional stability and long-term performance are essential. Its unique combination of wear resistance, structural integrity and weather resistance has made it one of the world's leading hardwoods for demanding exterior applications.

Typical applications of Ipé

Why engineers trust Ipé

Bridges, boardwalks and public decking are exposed to constant mechanical loads, heavy foot traffic and severe weather conditions. Only timber with exceptional structural performance can withstand these demands over many decades. Because of its outstanding compressive strength, excellent wear resistance and natural durability, Ipé has earned an international reputation for these demanding applications.

Exactly the same engineering benefits apply to premium fencing. Although a fence carries lower structural loads than a bridge, it still benefits from the remarkable dimensional stability, exceptional strength and outstanding lifespan that make Ipé one of the world's finest hardwoods.

Engineering performance meets architectural design

Because Ipé performs so exceptionally well from a structural perspective, architects enjoy far greater design freedom. Long uninterrupted slats, perfectly aligned joints and refined detailing remain possible year after year. Combined with our luxury fencing systems, hardwood gates and Ipé decking, the result is a seamless outdoor design where engineering excellence meets timeless architecture.

This is why Ipé continues to be specified for prestigious residential projects, public landscaping and high-end architectural developments throughout the world. Its remarkable technical properties provide the strength, while its rich natural appearance delivers lasting visual appeal.

Fire performance and outdoor safety

Safety is becoming an increasingly important consideration in luxury outdoor living. Where fencing is installed near pergolas, outdoor kitchens, fire pits or garden entertainment areas, the fire behaviour of the materials should always be taken into account. Owing to its exceptional density, Ipé behaves differently from lighter timber species.

Its extremely compact cellular structure slows the transfer of heat through the timber compared with many softer woods. Although Ipé is not fireproof, its density provides advantages over less dense timber species when incorporated into professionally designed outdoor spaces.

How density influences fire performance

Lighter timber species generally heat up more quickly because of their open cellular structure. The dense fibre composition of Ipé slows this process considerably. This is another reason why architects and landscape professionals specify Ipé for prestigious exterior projects requiring long-term durability, strength and reliable performance.

Ideal for outdoor kitchens, fire pits and covered patios

Luxury outdoor living spaces increasingly combine Ipé hardwood fencing with outdoor kitchens, pergolas, covered terraces and fire features. In these environments, choosing the right materials is essential. Always maintain sufficient clearance between open flames, barbecues or other heat sources and any timber construction, and follow the manufacturer's installation and safety recommendations.

Thanks to its exceptional density and outstanding structural stability, Ipé is perfectly suited to premium outdoor environments. Like every timber species, however, it should always be installed professionally. Good ventilation, correct structural detailing and safe distances from heat sources ensure your outdoor living space remains both beautiful and durable for many years.

Designed to perform in every British season

A premium fence must withstand constant exposure to rain, frost, strong winds, UV radiation and changing temperatures throughout the year. These demanding weather conditions require a hardwood with exceptional stability and natural durability. This is precisely where Ipé excels.

Its extremely dense cellular structure absorbs far less moisture than most hardwood species. As a result, Ipé remains remarkably stable, dries evenly after rainfall and is highly resistant to distortion. Even after many years outdoors, it continues to provide the structural integrity and premium appearance expected from one of the world's finest hardwoods.

Outstanding performance in all weather conditions

Natural ageing with timeless character

Like every premium hardwood, untreated Ipé gradually develops an elegant silver-grey patina. This natural weathering process only changes the colour of the timber and has virtually no effect on its strength, stability or lifespan. Many architects appreciate this sophisticated natural appearance.

If you prefer to preserve the original rich brown colour, simply apply a high-quality hardwood oil at regular intervals. This protects the surface, slows the weathering process and keeps the timber looking beautifully maintained for years to come.

Responsibly sourced Ipé hardwood

Choosing a premium hardwood fence is about more than appearance and durability. Increasingly, homeowners, architects and landscape designers also want confidence that the timber has been sourced responsibly. Ipé is recognised as one of the world's most durable hardwoods, making it an outstanding choice for long-lasting outdoor construction when sourced through responsible supply chains.

One of the greatest environmental advantages of Ipé is its exceptional lifespan. Because a professionally installed Ipé fence lasts for decades, it requires replacement far less frequently than many alternative timber species. This reduces raw material consumption, transport requirements and the environmental impact over the lifetime of the project.

Longevity is one of the most sustainable choices

Sustainability is not determined solely by how quickly a tree grows. The lifespan of the finished product is equally important. A premium Ipé fence can remain structurally sound and visually impressive for well over thirty years, meaning fewer replacements, less waste and a significantly lower long-term environmental footprint.

Built to last for future generations

We believe the most sustainable outdoor products are those that rarely need replacing. That philosophy is exactly why we specialise exclusively in Ipé hardwood. Its remarkable durability creates fencing systems that continue to deliver outstanding technical performance and timeless beauty for decades.

Why architects choose Ipé hardwood

Contemporary architecture demands materials that perform just as well technically as they do visually. Architects require timber that remains straight, stable and elegant for decades while integrating seamlessly with modern materials. Ipé consistently meets these requirements, which is why it is widely specified for luxury residential developments and architectural landscaping.

Its exceptional dimensional stability allows long uninterrupted slats, perfectly consistent spacing and refined detailing. Combined with concealed fixing systems, Ipé creates minimalist fencing that works beautifully alongside natural stone, porcelain paving, aluminium, exposed concrete and black steel.

Designed for modern architecture

Create more privacy and comfort with an Ipé hardwood fence

A modern fence does much more than define the boundary of your property. It creates privacy, enhances security and transforms your garden into a peaceful outdoor living space. Thanks to its exceptional density and premium construction, an Ipé hardwood fence provides an ideal combination of architectural design, durability and everyday comfort.

Different slat widths allow you to tailor the amount of privacy to suit your garden design. When combined with an EPDM privacy membrane behind the slats, the fence becomes virtually opaque while also helping to soften surrounding noise, creating an even more comfortable outdoor environment.

Advantages of an EPDM privacy backing

Transform your garden into an outdoor living space

An Ipé hardwood fence contributes far more than privacy alone. Its elegant horizontal lines, warm natural colour and concealed fixing system create an outdoor space with genuine architectural character. Instead of simply separating boundaries, the fence becomes an integral part of the overall garden design.

An investment that adds value for decades

A premium fence should be built to last. Rather than replacing timber every few years, more homeowners are investing in materials that continue to perform beautifully for decades. Ipé combines exceptional durability, minimal maintenance and timeless design, making it one of the most valuable long-term investments for any outdoor space.

Compared with lower-grade timber species that often require earlier replacement, Ipé retains both its structural integrity and premium appearance for many years. The result is lower maintenance costs, fewer repairs and outstanding value over the lifetime of the fence.
