Wood – Technical Specifications

Introduction

Wood worksurfaces are crafted from solid hardwood timber staves and finger jointed in length. The wood is then butt jointed and glued together along its width and finely oiled to create a beautifully water repellent surface. Wood worksurface products have a treasured history in commercial and residential environments, whether contemporary or classic in style.

Storage

Timber worktops should be stored at room temperature away from all sources of heat and moisture prior to installation. An external room without heating, ie. A garage is not suitable and could cause warping/swelling. Please either store flat or on their longest edge as instructed on the packaging. Never prop up a worktop vertically against a wall. Ideally stored horizontally on a sound and level surface, with timber battens placed between each blank at 600mm centres maximum.

When installed in a room with an Aga, acclimatisation is needed for a few days before being fitted.

DO NOT leave in an unheated room.

Tolerance

Tolerance in wood is ±2mm

Joints

Wood worksurfaces can be butt or mitre jointed dependent upon the edge detail. Mitre joints require additional support on site and require an additional length of worksurface to install.

Thermal Expansion

Wood worksurface products should ideally be kept at room temperature. In kitchens where temperatures can be either very cold (unoccupied site) or very humid, then the level of maintenance required is greater, especially in the immediate days / weeks after installation. In these cases extra coats of worksurface sealant will be necessary to prevent drying out and warping.

If an under oven, dishwasher, washingmachine or tumble dryer is to be installedunder the worksurface, a piece of aluminium foil should be adhered to the underside, with the foil face outwards. This will protect it from any intense heat or moisture. Allow a 3-4mm gap between the back edge of the worktop and the wall to allow expansion and contraction.

We don’t recommend timber wall cladding due to warping.

Overhangs and Support

Any overhang extending more than 300mm must be supported.

Hob & Sink Cut-outs

  • Sink cut-outs should be a minimum of 50mm from the worktop front edge. Aluminium foil should be applied to the edges of hob cut-outs.
  • There should be a minimum 200mm between hob cut-outs.
  • Hob cut-outs should be a minimum of 50mm from the worktop front edge.
  • Hob flange needs to sit on the aluminium foil around the cut-out, to avoid conducting too much heat into the wood and causing cracking.
  • When a worktop is to be fitted near to an Aga, Rayburn or similar allow a minimum gap of 4mm. Ideally a solid wood return should be fixed across the end grain to stop any splits occurring.

Upstands

It is important that upstands are fixed to the wall and not to the worksurface. There should be a 3mm gap between the worksurface and upstand, the only connection between upstand and worksurface should be silicone sealant, allowing natural movement of your worksurface.

Scratches

Wood worksurface products may be more prone to scratching than some other surfaces. The use of chopping boards and / or pastry mates is recommended in order to protect the surface finish.

Staining

It is important to remember not to leave wine glasses, dishes containing curry, wet copper – bottomed pans or similar items on wood worksurface products.

Repairable

Although the first few marks and scratches will stand out dramatically, hardwood has many unique qualities and with a little care and attention the passage of time can enhance its beauty. In the unfortunate event of sustaining damage, a wood worksurface maybe rubbed down and refinished, leaving it as good as new.

Stainless Steel Sinks

Please specify preferred method of undermounting Stainless Steel sinks. There should be a minimum 200mm between sink cut-outs. Drainer grooves can only be cut in the middle of staves, due to the nature of the construction of your worksurface.

If a waste disposal unit is fitted to an undermounted sink after installation, additional support will be required, otherwise your warranty may be invalidated.

Points of Note

Plastering or tiling should be completed after installation.

When fixing to the cabinets, only use slotted angle brackets to secure the worktop to the carcass. Always use washers with screws.

If a carcass has a solid top, or you can only secure through the top rail always drill an oversized hole (8 – 10mm) through the top of carcass and secure to the worksurface using a larger washer and screw. This allows the worksurface to slide over the washer in case of natural expansion or shrinkage.

Stave widths 40mm (±5) as standard. If unavailable 27mm (±1mm) Beech and Teak, 20mm (±1mm) on all other species will be supplied. Staves of an alternative thickness can be supplied but may have a longer lead time.

Random Stave Lengths

  • Finger jointed in the length and edge glued in the width Tolerances -1mm/±5mm Length
  • Finished to a 220 grit for blanks
  • Finished to a 500 grit for bespoke worksurfaces
  • Moisture content 10% ±2%
  • Sheridan Ultra worksurface sealant is brushed on leaving a clear, water repellent, satin/matt finish.
  • Individually shrink wrapped for delivery.
  • Available as either a “supply only” product saving over £400 per kitchen, or templated and installed by our experienced installation team.
