Tongue & Groove (T&G) siding’s tightly interlocking ridge/slot design makes it easy to install, sturdy, and remarkably versatile. It functions equally well when applied horizontally, diagonally, or vertically and even serves as sturdy flooring and ceiling panelling.
In all applications, T&G’s tight overlap between planks provides natural weather resistance and insulation (requiring no glue or caulking), facilitates blind nailing (hiding fastener heads for a cleaner finish), and provides structural stability (especially when wall studs are difficult to find). Nails need to penetrate about 1¼” of solid wood behind T&G planks, so existing walling or thin battens are often sufficient.
Our reversible T&G combines two essential T&G styles in a single product: one face features a flush joint, and the other features a v-groove (with two edges beveled at a 45° angle).
(Also called bevel siding, lap siding, weatherboard, and clabbard)
Clapboard siding’s narrow wedge design is the standard look that most vinyl siding attempts to replicate. Wood clapboarding creates a rustic aesthetic that is easily maintained and repaired. Compared to vinyl, it is a better insulator, more weather-resilient, and longer-lasting if well maintained.
In all applications, clapboard’s deep overlap between planks ensures it sheds water well (requiring no glue or caulking). To ensure effective water shedding, clapboard is recommended for horizontal applications only.
Our plain bevel clapboard requires only a single row of fasteners along the bottom of each plank—just above the overlap with the plank below. As a general rule, clapboard planks should overlap by 1” for every 6” of plank width—with a minimum overlap of 1”.
Shiplap siding’s double rabbet design produces stable joints and characteristic subtly shadowed channels between planks, serving as accent lines that are both warming and modern. Shiplap may be installed horizontally, on a slant (<45° angle), vertically (when on post-and-beam walls), or on sloped ceilings. Its stability also makes it ideal for constructing small doors and shutters with minimal framing and cross supports.
In all applications, shiplap’s wide overlap between planks provides a strong barrier against moisture infiltration (requiring no glue or caulking) and reduces face nailing (leaving minimal fastener heads visible). In exterior applications, shiplap’s channels wick away rainwater and speed drying. In interior applications, its accent lines can emphasize room size and unify open-concept spaces.
Our nickel-gap shiplap siding is available dressed on four or three sides. Both dressing options are designed to install flush but dry to produce a ⅛” channel. Channels can be widened easily by using spacers during installation.
As North America’s densest softwood, tamarack larch has strength and stability comparable to a hardwood. Its high resin content produces decking that is naturally rot-resistant and that finishes well and rarely splinters. Its attractive striped pattern ranges in colour from yellow-brown to whitish. Aged in harsher weather, the wood eventually turns a stately silver-grey.
Our tamarack larch decking comes in standard thickness (1¼”), in 4″ or 6″ widths, and in 8′ or 10′ lengths (with limited quantities in 12′, 14′, and 16′ lengths). All decking is dressed on three sides with two eased edges.
To prevent warping and twisting, tamarack larch decking should be immediately installed or properly stored. Store decking in even, flat layers. Use a breathable rain cover, such as slab wood or roofing tin, and dried blocks to elevate the bottom layer. When storing decking at over 15°C for a period longer than a few weeks, use dried stickers between layers, placing a sticker every 1’ of decking length plus a sticker near each end.
