Build your whole deck around our teak boards here. The calculator walks you through each part, from subframe and joists to clips, starter clips, fascia and edging trims. Enter your length and width in metres and skip any step for parts you already have. Finish the edges with matching teak bullnose boards, or turn the mocha face outward for a contrasting frame from the same board. If you like the tone but want a more rustic, weathered-wood look, our light oak composite decking sits close to teak with a heavier grain.

Capturing the exotic warmth of natural teak, our Teak Capped Composite Decking Board delivers a rich, golden-brown finish to any garden project. As one of the first brands to bring dual-colour technology to the UK market almost seven years ago, this board features a reversible design, allowing you to flip the profile to choose between a light Teak or a dark mocha brown to perfectly match your space.
Its high-performance 0.5mm PE layer provides an advanced protective shell against moisture, stains, and fading. Because it absorbs significantly less moisture than uncapped alternatives, common garden spills like BBQ grease, wine, or beer wipe away effortlessly. The grooved edges support hidden fasteners for a flawless, splinter-free finish, making this board a go-to favourite for professionals and DIYers alike.

Expert Advice On Our Teak Composite Decking
Want to know more? Our in-house expert, Allan, gives his take on our Teak Composite Decking, and we’ve selected some of our best guides to help you decide if this is the right choice for you.
A Word from Our Expert, Allan Jeffrey BSc. Eng. (Hons), Composite Materials Specialist, Environmentalist, and CEO of Ultra Decking:
We developed our Signature Teak board to eliminate the negative feedback we saw on older uncapped and even previous capped boards. We were actually one of the first to bring this reversible dual-colour design to the UK market almost seven years ago, giving you the choice of a light or dark brown aesthetic on a single board.
The real game-changer for homeowners, though, is the advanced 0.5mm PE layer. This capped shell absorbs significantly less moisture than standard boards. Because it is so tightly sealed, common garden hazards like BBQ grease, spilled wine, beer, and winter algae just wipe straight off. Plus, through years of production testing, we managed to completely remove the microscopic “thin hairs” that used to sit on the surface of older capped boards. Without those hairs to trap static dust and dirt, your deck stays looking pristine with a fraction of the maintenance.

Teak Decking Board Specifications
Check the Teak Decking board’s dimensions below before you measure up, so steps, borders and any features in your design work out exactly. If you’re working the boards out by hand rather than with our calculator, An expert tip is: allow for the gap between boards: a 138 mm board needs a 3 mm side gap, so count each board as 138 + 3 mm across.

FAQ About Our Teak Capped Composite Decking
1 Will the teak colour fade over time?
All composite boards soften slightly in colour over time, but the polyethylene cap on this board is designed to resist UV fading, so the colour stays richer for longer than an uncapped board.
2 What does capped mean, and how is it different from your uncapped boards?
A capped board has a 0.5mm polyethylene shell bonded over the wood-plastic core. The core is the same type of wood fibre and HDPE composite as our uncapped Home Choice and Premier boards, but the cap seals the surface, so it absorbs far less moisture, resists stains such as grease, wine and algae, and holds its colour better. That is why capped boards carry a 25-year warranty instead of 10.
3 Which side is teak and which is mocha?
Every board has the golden-brown teak wood grain on one face and a darker mocha brown on the reverse. Choose which face goes up before you fix each board, and keep the same face up across the deck. You can also turn the mocha face up on a few boards to make a border or picture frame without ordering a second colour.
4 Are these teak capped decking boards easy to install by myself?
Yes. The boards are made for straightforward installation with our hidden fastener system. If you can measure and drive a screw, you can build a deck in a weekend; our installation guide walks through each step.
5 How many teak boards will I need?
Use the quick calculator on this page: enter your deck’s length and width for a board count, and tick the 5% cutting margin to cover trimming and cuts. Each 3.6m board covers roughly 0.497 m². If you are laying a mocha border from flipped boards, count those boards in your total.
6 Can I install the capped composite decking over grass or gravel?
Yes you can, but ensure you allow a gradient and its advisable to raise you deck 300mm in height to support drainage and air flow. You must also use a subframe c16 timber or aluminium joists to ensure long lasting strength and durability.
7 Is this teak capped decking suitable for families with children or pets?
Yes! The capped surface is splinter-free, slip-resistant, and but they can get a little hot in the summer so make sure wear shoes or slides.
8 Should I order samples first to see the dual finish?
Yes. Order a free sample to see both faces in your own garden light. Screens only tell half the story; the sample shows you the true colour and texture of each side.
