To calculate how much interior cladding you need, measure each wall’s height and width, then multiply to get the total square metres. Subtract any large openings like windows or doors. The profile you choose will determine how much timber is required, based on its cover width (the visible part after installation). Our calculator simplifies this for you — just enter your wall dimensions and profile selection to get an accurate lineal metre estimate. If you’re unsure how to measure or want to check your numbers against a floorplan, our team can help guide you through it.

Board width is the full physical width of a timber board, while cover width refers to how much of that board is visible once installed — taking into account overlaps, rebates, or tongue-and-groove joints. For accurate ordering, it’s essential to calculate based on cover width. Our calculator does this automatically when you select your cladding profile, so you don’t need to manually adjust for overlaps. If you’re comparing profiles, we can also provide datasheets that include board and cover dimensions.

Durable hardwoods like Spotted Gum, Ironbark, Tallowwood and Silvertop Ash perform exceptionally well in New Zealand’s weather conditions. These timbers offer natural resistance to moisture, rot, and UV exposure. Reclaimed timber is also a strong choice if you’re looking for a sustainable option with character. LMA Timber specialises in architectural-grade, sustainably sourced hardwoods, and we can advise you on which species are in stock and suitable for your climate zone.
Yes, timber cladding can be used in bathrooms and kitchens, provided it’s installed correctly with appropriate ventilation and finishing. In high-moisture zones like splashbacks or around sinks, we recommend avoiding direct water contact or sealing the timber with a moisture-resistant finish.
Timber can still move indoors, especially with seasonal humidity changes, but far less than in outdoor conditions. Choosing stable species like Tallowwood or reclaimed hardwoods helps reduce movement. It’s important to acclimate boards on-site before installation and leave expansion gaps where needed. We can provide stability ratings and advice based on your chosen species and indoor conditions.
Yes, interior timber cladding can be installed over gib or plasterboard, either by direct fixing or using battens depending on the board thickness and desired aesthetic. This is a popular choice for feature walls. We can advise on installation best practices for your existing wall setup and supply the right board profiles to suit.
Absolutely. Timber is commonly used in cafes, offices, retail spaces, and hospitality venues to create warmth and character. Hardwood cladding is especially popular because it’s durable and can withstand high-traffic areas. We’ve supplied timber for a range of commercial interiors across NZ — we can help you match a profile and species to your concept and durability needs.
Finishing helps protect your cladding and brings out the grain of the timber. Clear oils preserve natural tones, while tinted finishes can warm or soften the look. For commercial or high-contact areas, a harder-wearing finish may be recommended. We can supply cladding pre-oiled or untreated depending on your install timeline and desired look.
Delivery times depend on the species, profile, and whether the timber is pre-oiled or custom-milled. Standard interior profiles are often available within 5–7 business days, but custom runs or reclaimed stock may take longer. After using the calculator to estimate your quantities, get in touch with us and we’ll confirm lead times and delivery options for your area.
When installed correctly and maintained, hardwood cladding can last 30 years or more. High-density species like Ironbark and Spotted Gum are naturally resistant to decay and insects, especially when paired with a well-ventilated cavity. Maintenance includes oiling or sealing the timber every one to two years if you want to preserve the original colour. We can supply pre-oiled boards and also recommend low-maintenance finishes depending on your preferred look and exposure level.
