Description

What prevents this timber installation from rotting?

To combat organic decay, this 16ft x 16ft wooden structure relies on pressure-treated timber that actively helps resist moisture damage. Sourced from sustainable wood forests, the heavy-duty 90mm x 90mm columns, overarching 28mm x 120mm joists, and the 28mm decking boards undergo strict chemical impregnation before leaving the factory. This intensive preservation process deeply soaks the pine grain, empowering the massive 16 x 16 frame to withstand persistent dampness during unpredictable springs. Sealing the softwood with a secondary water-repellent topcoat after construction will further aid in blocking UV bleaching.

Does the kit supply a dedicated walking surface?

Equipped with a 28mm grooved pine floor, this 16 x 16 timber pergola establishes a highly functional, flat leisure zone directly below the 28mm x 120mm overarching canopy. Shaped with a textured upper profile, the 28mm floorboards yield necessary underfoot friction, significantly reducing slip risks following sudden downpours. Spanning the entire 16ft x 16ft footprint, the heavy-duty pine base effortlessly manages dense foot traffic and heavy domestic loads without flexing.

How does the heavy-duty framework maintain its shape?

Structural integrity across this 16ft x 16ft wooden pergola is guaranteed by joining thick 90mm x 90mm posts to dense 28mm x 120mm roof joists. This cavernous timber framework utilises diagonal corner bracing to prohibit lateral swaying, retaining a perfectly square footprint throughout its operational lifespan. Above, the slatted softwood rafters disperse physical stress equally across the sprawling 16 x 16 dimensions, certifying the garden canopy combats turbulent gales effectively. Once fastened securely onto a level site, the substantial wooden uprights ensure the exterior boundary remains locked in place.

How to Use a 16ft x 16ft Wooden Pergola With Decking

Harness the vast 16 x 16 proportions to configure a comprehensive multi-use entertaining hub directly upon the 28mm grooved pine floor. The colossal decking affords the necessary square footage to establish an outdoor cinema lounge on one side while retaining ample room for a multi-seater dining layout opposite. Meanwhile, the overarching 28mm x 120mm roof joists cast segmented shade across the entire footprint, keeping guests comfortable while ensuring uninterrupted airflow during humid August afternoons.

Alternatively, convert the sprawling 16ft x 16ft dimensions into a spectacular horticultural sanctuary by training climbing flora up the 90mm x 90mm posts. Substantial stone planters sit perfectly flush on the sturdy 28mm decking, giving aggressive climbers like clematis an unobstructed route to scale the wooden pillars. As the vegetation expands laterally through the heavy-duty joists, it generates a thick, living canopy over the pressure-treated softwood, firmly anchoring the massive architectural framework into your broader landscaping layout.

About Your Order

The Shire pergola and decking is made in the UK with sustainably sourced timber. You get a top-quality wooden decking with a low carbon footprint made from ethically sourced materials. The clean and straightforward design makes it easy to assemble, please note that the fixtures and fittings required are not included as part of your order. The decking has a 10-year anti-rot guarantee and a 12-month manufacturer's warranty to enjoy it for many seasons.

Pergola and Decking Maintenance

The Pergola and Decking is made with pressure-treated timbers. The pressure treatment process forces preservatives into the wood under high pressure. It provides effective long-term protection against rot and fungus. Pressure treatment is almost colourless except for a light green tint caused by the copper content in the preservative. Over time, the treatment greys, but this does not affect the quality.

Shire, the manufacturer, advises that you must apply a wood stain, paint or waterproofing topcoat to make the product more water-resistant. The treatment must be carried out immediately after installation. Using the treatment after installation, followed by consistent annual treatment of the garden arbour, will maintain the high-quality finish and is a requirement of the 10-year anti-rot guarantee. A 1-year manufacturer's warranty is included as standard.

To treat the decking and pergola, elbec recommends Protek wood treatment. Browse our Protek Royal Exterior Wood Finish Paint range to find the best paint colour to add your personalised finish. In the options section, we’ve included popular colours and a Wood Preserver+ for use underneath your colour choice.
