Timber cladding for Singapore’s climate
Timber cladding for Singapore’s climate
Timber cladding for Singapore’s climate
Timber cladding brings warmth to façades, feature walls, soffits and screens. In Singapore it has to cope with sun, rain and humidity on every exposed face, so the material matters. Calvary Carpentry supplies and installs cladding in modified, fortified and reconstituted timbers, as well as classic hardwoods.
Our cladding work includes the seedpods at Mandai Rainforest Resort, Reflections at Keppel Bay, the external cladding at Singapore Management University and private homes such as the Swiss Club residence and Kew Drive.

Choosing a cladding material
Each option balances appearance, upkeep and fire performance differently. Here is how our cladding materials compare.
Accoya®: FSC®-certified modified timber, Durability Class 1, dimensionally stable; can be fire-treated for higher requirements. Best for: Natural timber façades, screens and soffits.
Sicaro: FSC®-certified fortified timber, colour-infused through the core, Durability Class 1, ASTM E84 Class A. Best for: Coloured cladding where fire performance matters.
Onewood: Homogeneous reconstituted timber that can be re-sanded; Class 1 fire-retardant treatment available. Best for: Large public areas, interior walls and ceilings.
Solid hardwood: Teak and other hardwoods, often finished with OSMO. Best for: A classic hardwood look, as on teak-clad pool walls.
Silverwood finish: A natural coating that turns weathered timber an even, silvery patina. Best for: Renewing existing cladding instead of replacing it.
Screens, louvers and soffits
Screens, louvers and soffits
Beyond walls, we build fixed and sliding timber screens, louvers, sun screens and soffits. Fixed screens give privacy while letting air through, as on the bridge into a Mount Sinai home. Sliding Accoya® screens open up the façade of a private residence, and on Kew Drive the Accoya® ceiling continues from outside to inside.
Keeping cladding looking good
Accoya®: leave it to weather to silver-grey, or keep its colour with an oil or coating that is renewed periodically.
Sicaro: because the colour runs through the core, washing the surface brings the colour back after weathering.
Weathered timber: our Silverwood coating turns it an even silvery patina, so no timber is discarded.
Hardwoods: periodic cleaning and an OSMO maintenance coat keep the finish fresh.

Frequently Asked Questions
Which timber cladding lasts longest in Singapore?
Accoya® and Sicaro are both rated Durability Class 1, the highest class, and Accoya® carries a 50-year durability warranty. Both are made for exterior use in tropical conditions.
Is timber cladding fire-rated?
Sicaro achieves ASTM E84 Class A surface-burning performance, Onewood can be treated to Class 1 fire retardancy, and Accoya® can be fire-treated to meet higher requirements.
Does timber cladding need maintenance?
It depends on the look you want. Timber can weather naturally to grey, or be oiled or coated to keep its colour. Sicaro washes back to its colour, and Silverwood renews weathered timber with an even silver finish.
Can you clad interior walls and ceilings too?
Yes. We install Onewood and Kandinsky timber on interior walls and ceilings, and ALPI wood veneers for walls and joinery.

Singapore
At a residence on Chee Hoon Avenue, the outdoor balcony features a solid teak soffit with a warm, natural tone. Inside, the halls and living areas are finished in Timberwise wood flooring laid in a triangular pattern, creating a distinctive rhythm through the home.
Scope of work
Calvary Carpentry delivered the teak balcony soffit, timber screens and cladding outside, and the patterned wood flooring inside.
Solid teak outside, patterned flooring inside
A timber floor has to handle daily foot traffic and Singapore's humidity while keeping its colour and finish, so stability and a durable surface matter as much as the look. Timber ceilings and soffits bring warmth and softer acoustics to a space, and need a stable material that will not warp or sag in humid air. Solid timber gives real, full-depth wood character, and it can be sanded and refinished over its life to renew the surface.
Care and maintenance
Solid timber benefits from periodic cleaning and re-oiling or re-coating, and it can be sanded back and refinished to look new again. Timber refinishing and OSMO oils are available for when a surface needs renewing.

Enabling Village
At Enabling Village in Singapore, benches and railings are crafted in Onewood homogeneous reconstituted timber. The same durable material forms the timber cabanas and wall cladding, creating warm, welcoming spaces that reflect the Village's mission: a place where doors are open to all.
Scope of work
Calvary Carpentry supplied and installed Onewood benches, staircase railings, trellises, cabana structures, wall cladding and panels across the community space.
Why Onewood for a public community space
Stairs take concentrated wear on every tread and nosing, so they need a hard-wearing surface and a finish that matches the surrounding floor. Timber ceilings and soffits bring warmth and softer acoustics to a space, and need a stable material that will not warp or sag in humid air. Onewood is homogeneous reconstituted timber (HRT): the same from surface to core, so it can be re-sanded to reveal fresh grain. It can be made in large dimensions for seamless pieces and treated to Class 1 fire retardancy.
Care and maintenance
Because Onewood is the same all the way through, worn or marked areas can be re-sanded to reveal a fresh surface instead of being replaced. Timber refinishing and OSMO oils are available for when a surface needs renewing.

Cove Grove

17 Cove Grove
Within Sentosa Cove, this home on Cove Grove pairs a silvery roof with timber cladding, each surface aged with Calvary's Silverwood timber coating. Made from citrus compounds, it gently turns weathered wood into a resilient, silvery patina: no timber discarded, only renewed strength.
Scope of work
Calvary Carpentry restored the existing timber cladding and panels and applied the Silverwood coating, renewing the façade instead of replacing it.
Why renew timber cladding with Silverwood
Timber ceilings and soffits bring warmth and softer acoustics to a space, and need a stable material that will not warp or sag in humid air. Cladding, screens and louvers are exposed on every face, so the timber must hold its shape and resist decay to keep clean lines for years. Silverwood is Calvary's natural timber coating made from citrus compounds: it gently turns weathered wood into an even, resilient silvery patina instead of patchy greying. Sanding back and re-varnishing removes the worn top layer of a timber floor, so the same boards can look new again instead of being replaced.
Care and maintenance
A Silverwood finish lets the timber keep ageing gracefully; the coating can be renewed when the surface needs refreshing, with no timber discarded. After refinishing, regular sweeping and a lightly damp mop keep the new finish fresh, and the floor can be refinished again in future. Timber refinishing and OSMO oils are available for when a surface needs renewing.

Mandai Wildlife Reserve
Calvary Carpentry crafted the iconic timber seedpods at Mandai Rainforest Resort, Singapore's first SLE resort, set within the Mandai Wildlife Reserve. The project prioritised non-toxic, green-certified materials with long-term durability and a low environmental impact, in keeping with the resort's focus on conservation.
Scope of work
We supplied and installed Accoya® and Onewood timber across the seedpod structures: ceilings, wall cladding, louvers and sun screens that wrap the resort's distinctive forms.
Why Accoya® and Onewood for an eco-resort
Timber ceilings and soffits bring warmth and softer acoustics to a space, and need a stable material that will not warp or sag in humid air. Cladding, screens and louvers are exposed on every face, so the timber must hold its shape and resist decay to keep clean lines for years. Accoya® is FSC®-certified modified timber made by acetylation. It is rated Durability Class 1 (EN 113), resists rot and termites, stays dimensionally stable through Singapore's humidity, and carries a 50-year durability warranty. Onewood is homogeneous reconstituted timber (HRT): the same from surface to core, so it can be re-sanded to reveal fresh grain. It can be made in large dimensions for seamless pieces and treated to Class 1 fire retardancy.
Care and maintenance
Accoya® can be left uncoated to weather to a silver-grey patina, or finished with an oil or coating to keep its colour; periodic cleaning and re-coating keep a coated finish looking fresh. Because Onewood is the same all the way through, worn or marked areas can be re-sanded to reveal a fresh surface instead of being replaced. Timber refinishing and OSMO oils are available for when a surface needs renewing.

Holland Park
2025

Holland Drive
At this home in Holland Park, Dasso XTR bamboo decking surrounds the swimming pool, paired with teak cladding finished in OSMO for lasting protection and a lustrous, refined sheen.
Scope of work
We supplied and installed the pool decking, teak wall cladding and panels, and applied the OSMO finish to the cladding.
Why bamboo decking and teak cladding by the pool
Outdoor decks in Singapore face strong sun, heavy rain and humidity all year, so the boards must stay stable, resist rot and insects, and remain comfortable and safe underfoot. Timber ceilings and soffits bring warmth and softer acoustics to a space, and need a stable material that will not warp or sag in humid air. Dasso XTR is compressed (reconstituted) bamboo decking: dense and hard-wearing, and made from bamboo, one of the fastest-growing renewable materials. Teak is naturally rich in oils, resists moisture and termites, and takes an OSMO finish well.
Care and maintenance
OSMO-oiled surfaces are maintained by cleaning and periodically applying a fresh coat of oil, without sanding back to bare wood. Solid timber benefits from periodic cleaning and re-oiling or re-coating, and it can be sanded back and refinished to look new again. Timber refinishing and OSMO oils are available for when a surface needs renewing.

Kampong Gelam
Collective Memories of Kampong Gelam was a quiet, contemplative passage designed by Super Fuse Collective for Archifest 2023, hosted by the Singapore Institute of Architects. Built in Accoya® timber and anchored with Calvary Composite® decking, the installation formed a clean, tactile walkway honouring the district's layered heritage.
Scope of work
We supplied and built the installation's timber structure, screens, soffits and cladding in Accoya®, with Calvary Composite® decking for the walkway.
Why Accoya® and composite for an outdoor installation

Timber ceilings and soffits bring warmth and softer acoustics to a space, and need a stable material that will not warp or sag in humid air. Accoya® is FSC®-certified modified timber made by acetylation. It is rated Durability Class 1 (EN 113), resists rot and termites, stays dimensionally stable through Singapore's humidity, and carries a 50-year durability warranty. Calvary Composite® is a wood-plastic composite made with up to 95% recycled materials. Upkeep is usually just sweeping and a soap-and-water wash, and with the EZ-rail® clip system boards can be lifted out for access underneath.
Care and maintenance
Accoya® can be left uncoated to weather to a silver-grey patina, or finished with an oil or coating to keep its colour; periodic cleaning and re-coating keep a coated finish looking fresh.
