19x100mm 4.2m Untreated TGV Matchboard Cladding

About

Our 19x100mm Untreated TGV Matchboard Cladding provides an attractive, traditional timber finish for internal walls, ceilings, garden rooms, summerhouses, sheds, workshops and other timber buildings. Manufactured from softwood, these boards feature a smooth planed surface and a distinctive V-jointed tongue-and-groove profile, making them an excellent choice for decorative timber panelling, internal lining and refurbishment projects.

Each board features a projecting tongue along one edge and a corresponding groove along the opposite edge, allowing adjoining boards to interlock neatly. The chamfered edges create the characteristic V-shaped joint between boards, providing a consistent, attractive appearance. The nominal 19x100mm section typically finishes at approximately 14.5x94mm, although actual dimensions and effective cover widths may vary between manufacturers.

The thicker 19mm nominal section provides a more substantial alternative to 16x100mm matchboard, making it particularly suitable for projects where a sturdier timber lining or more pronounced traditional finish is preferred. Supplied untreated, the boards retain their natural softwood colour, grain and knots and can be painted, stained, varnished or oiled to complement their surroundings.

These boards can be installed horizontally or vertically onto suitable timber battens or framework, with appropriate fixings and allowance for natural timber movement. As the timber is untreated, it is primarily intended for internal or suitably protected applications. External use requires an appropriate timber specification, preservative treatment and protective finishing system.

Actual finished dimensions, machining profiles, effective cover widths and timber appearance may vary between manufacturers and suppliers. If you need to match existing timber cladding, please contact us before ordering to confirm compatibility.
