How do I install a pergola on a timber deck?

OUTMOS pergolas can be installed on a timber deck, provided the deck has adequate structural support.

The pergola posts should not be fixed only to the decking boards, as the boards themselves are not designed to support the structural loads of a pergola. Instead, the posts must be securely anchored to the structural framing beneath the deck or to suitable concrete footings, depending on the deck construction.

As every timber deck is built differently, the appropriate fixing method will vary from project to project. We recommend having your deck assessed by a qualified builder or engineer to ensure the pergola is installed safely and in accordance with local building requirements.

NO, The height is not customisable as it is fixed at 2.5m by default. If you need to make it shorter, you can consider trimming the legs, although it's essential to note that doing so will void the warranty.

YES, once the pergola is set up, it's possible to relocate it if needed, or it can be disassembled for transportation when moving to a new residence.

YES, Our OUTMOS pergola is designed to endure extreme weather conditions when installed correctly, including almost hurricane-force winds, heavy snow loads, rain, and intense heat. It is constructed to be sturdy and robust, providing long-lasting durability

What is the wind rating of an OUTMOS pergola?

OUTMOS aluminium louvred pergolas have been structurally engineered and certified by an Australian structural engineer to achieve a design wind rating of up to 35.67 m/s (128 km/h) when installed correctly in accordance with our installation instructions and engineering specifications.

This certified wind rating is supported by engineering calculations and documentation, giving homeowners confidence that the pergola is designed to perform in demanding Australian weather conditions.

The actual wind performance depends on factors such as the pergola model, dimensions, installation method, site conditions, and compliance with the engineering specifications. For the best performance during strong winds, we recommend leaving the louvres fully open and retracting any pergola blinds.

Detailed engineering calculations and the certified wind rating are included in the engineering documentation supplied with our standard pergolas.

Our models are built to endure typical weather conditions. The roof's S-shaped blades guide rainwater into a guttering system, which directs the water down through the posts.

However, during severe weather or heavy rain, there might be slight leakage. This is due to the drainage system's capacity being exceeded, similar to what can happen with house gutters or external drains.

YES, The pergola is entirely resistant to rust because it is constructed from premium-grade aluminium, specifically the 6005 T5 alloy.

NO, It's not recommended to suspend a hammock or hanging chair within an OUTMOS pergola.

Our OUTMOS pergola is designed to be incredibly low-maintenance, alleviating any concerns about servicing. The frame can be easily cleaned with common cleaning materials and can also withstand periodic jet washing. Additionally, you can keep the
gutters clear by using a jet wash as well.

The pergola can be easily installed and secured on a variety of flat and stable surfaces, as long as the space's dimensions are appropriate. These compatible surfaces include concrete, resin, paving slabs, wooden and composite decking, porcelain tiles, and various types of tiles.

Although not mandatory, we recommend placing concrete pads underneath the porcelain tiles at the locations where the pergola's feet will be placed. Another option is to consider a complete concrete base rather than sand or hardcore. This can significantly improve the stability and durability of the structure.

Before installation, it's advisable to consult with qualified and professional technicians for guidance.

Yes. OUTMOS pergolas feature a concealed drainage system that collects rainwater through the integrated gutters, channels it down through the inside of the posts, and discharges it near the base of each post.

If you wish to connect the pergola drainage to your property's stormwater system, this can generally be achieved during installation. As every property has a different drainage layout, we recommend consulting a licensed plumber to ensure the connection complies with local plumbing regulations and is suitable for your site.

The required clearance depends on your pergola size, installation method, and site conditions, so there is no single minimum clearance requirement.

To ensure a safe and efficient installation, there should be sufficient space around the pergola for assembly, lifting components into position, and securing the structure to the ground. If the pergola is being installed on individual concrete footings, the footing size is typically at least 450 × 450 mm, subject to the engineering design and local building requirements.

If the pergola is being installed on an existing concrete slab or decking, the available space and supporting structure should be suitable for the pergola size and installation method.

If you're unsure whether your site has sufficient clearance, our team can help assess your project before ordering.

Yes. The pergola posts can be shortened if a lower installation height is required.

If you require a different height, we recommend ordering a custom-made pergola manufactured to your required dimensions whenever possible.

The posts may also be trimmed on site by a qualified installer or experienced tradesperson. However, please note that cutting or modifying the posts will void the product warranty. If you are unsure which height is best for your project, our team is happy to help you choose the most suitable option before ordering.

Can I install LED lights myself?

Yes, but it depends on which pergola model you have.

• Manual Pergolas (Sunrise Series): You can install your own LED strip lights, including solar-powered options, if you wish. As these pergolas are not pre-designed with integrated LED channels, the lighting will need to be surface-mounted.
• Motorised Pergolas (Twilight & Skyline Series): The integrated LED lighting is factory-installed and fully wired before delivery. No additional installation is required—simply connect the pergola to power and the lights are ready to use.

If you're unsure which lighting option is best for your project, our team is happy to help you choose the most suitable pergola before ordering.

What happens during heavy rain?

OUTMOS pergolas are designed with a concealed internal drainage system that effectively manages normal rainfall. Rainwater is collected through the louvres, channelled into the integrated gutters, and discharged through the inside of the pergola posts.

During exceptionally heavy rainfall or severe storms, there is a possibility that the drainage system may temporarily exceed its maximum capacity, which could result in minor overflow. This is similar to how residential gutters may overflow during intense rain events.

To maintain the best drainage performance, we recommend periodically removing leaves and debris from the louvres and internal gutters to ensure water can flow freely.

Should I leave the louvres open during strong winds?

Yes. During strong winds, we recommend leaving the louvres in the fully open position. This allows wind to pass through the pergola, reducing wind pressure on the structure and helping minimise the risk of damage.

If strong winds, storms, or severe weather are forecast, we also recommend fully retracting any pergola blinds or other accessories to help protect them from unnecessary wind loads.

Following these recommendations will help maximise the performance and longevity of your OUTMOS pergola.

How do I install a pergola on a concrete slab?

OUTMOS pergolas can be installed on an existing concrete slab, provided the slab is structurally suitable for supporting the pergola.

The pergola posts are securely fixed to the concrete using anchor bolts. To ensure a safe and durable installation, the concrete slab should have sufficient strength, thickness, and reinforcement to support the structural loads of the pergola.

As every property is different, the suitability of an existing concrete slab will depend on its construction and condition. If you are unsure whether your slab is suitable, we recommend consulting a qualified builder or structural engineer before installation.

How do I install a wall-mounted pergola onto a brick wall?

OUTMOS wall-mounted pergolas are supplied with dedicated wall-mount brackets that are specifically designed for secure installation onto suitable brick walls.

The installation process is generally as follows:

1. Position and fix the wall brackets
   The supplied wall brackets are securely fixed to the brick wall using heavy-duty expansion anchors. The wall must be structurally sound and capable of supporting the pergola load.
2. Install the wall beam
   The wall beam is designed with an integrated mounting groove, allowing it to hook directly onto the installed wall brackets for easy positioning during installation.
3. Secure the wall beam
   Once the wall beam is correctly positioned, it is bolted to the wall brackets from underneath to create a strong and stable connection.
4. Complete the pergola assembly
   The remaining pergola components, including the posts, front beam, louvres, and accessories, are then assembled in accordance with the installation manual.

Please note that the appropriate fixing method will depend on the type of wall construction, such as single brick, double brick, cavity brick, or reinforced masonry walls. If you are unsure whether your wall is suitable, we recommend consulting a qualified builder or structural engineer before installation to ensure the wall can safely support the pergola and complies with local building requirements.

How do I install a wall-mounted pergola onto the fascia or eave of a house?

A wall-mounted pergola can be installed at the fascia or eave of a house only if there is adequate structural support behind the eave.

The installation process is generally as follows:

1. Inspect the roof structure
   Before installation, the roof structure should be checked to confirm that suitable structural members, such as rafters or roof framing, are available to support the pergola.
2. Install a structural mounting board (wall plate)
   A structural timber mounting board (also referred to as a wall plate) is securely fixed to the rafters or other structural framing behind the eave. This board provides the structural support required for the pergola.
3. Install the wall brackets
   The supplied wall brackets are then fixed securely onto the structural mounting board using the appropriate fixings.
4. Install the wall beam
   The wall beam is designed with an integrated mounting groove, allowing it to hook onto the wall brackets before being securely bolted into position from underneath.
5. Complete the pergola assembly
   Once the wall beam has been secured, the remaining pergola components, including the posts, front beam, louvres, and accessories, are assembled in accordance with the installation manual.

Important: The fascia board and eave lining are not structural load-bearing components and should never be used to support the pergola on their own. The pergola must always be fixed back to the house's structural framing.

Because roof construction varies between homes, we strongly recommend having the installation assessed by a qualified builder or structural engineer to confirm the most suitable fixing method and ensure compliance with local building requirements.

Are the louvres sloped? How does water drain from an OUTMOS pergola?

The answer depends on the pergola type.

Wall-mounted pergolas

Most OUTMOS wall-mounted pergolas are designed with a slight fall away from the house. The louvres run perpendicular to the wall, allowing rainwater to naturally flow away from the building toward the front of the pergola.

Please note that the standard (non-Heavy Duty) 3 × 6 m and 4 × 6 m wall-mounted models are exceptions and do not incorporate this built-in fall.

Freestanding pergolas

All OUTMOS freestanding pergolas are designed with level (non-sloping) louvres. The drainage system is engineered to operate effectively without requiring the roof to be installed on a slope.

How does the drainage system work?

When the louvres are fully closed, rainwater is collected by the integrated drainage channels built into the louvre system. The water then flows into the concealed perimeter gutters surrounding the pergola.

From the gutters, the water enters the internal drainage openings at the top of each post, travels down through the hollow posts, and finally exits through the drainage outlets at the base of the posts.

This concealed drainage design keeps all water management hidden within the pergola structure, providing a clean appearance while efficiently directing rainwater away from the outdoor living area.
