Cladding & Siding
Transform exterior environments with siding and cladding built to last. At Mason’s Mill & Lumber, we supply architects, builders, and contractors with precision-milled exterior materials designed for long-term beauty and performance.
From modern rainscreen systems to traditional lap siding, our mill offers the quality, flexibility, and speed your project demands.
Thermally modified ash rough lumber offers the classic, timeless sophistication of real wood combined with the exceptional durability that results from the thermal modification process. When it comes to rot resistance and stability, this ash rough lumber will take on any other real wood product, including tropical woods and other modified hardwoods. Meticulous milling means clean lines, tight seams and easy installation.
The thermal wood process modifies each board completely, all the way through to the core, leading to unequalled durability and stability without sacrificing the natural qualities of real wood.
Ash is regularly used for furniture, flooring, doors, architectural millwork and moulding, kitchen cabinets, paneling, tool handles, baseball bats, hockey sticks, skis, oars and turnings. The sapwood is light-colored to nearly white and the heartwood varies from greyish or light brown, to pale yellow streaked with brown. The wood is generally straight-grained with a coarse uniform texture.
The degree and availability of light-colored sapwood, and other properties, will vary according to the growing regions.

Frequently Asked Questions
Both protect and define a building’s exterior, but “siding” typically refers to materials used on residential homes, while “cladding” is the broader architectural term used for commercial or custom applications. At Mason’s Mill & Lumber, we supply both—custom-milled to suit your project’s design and performance requirements.
Yes. Our in-house mill can match or reproduce nearly any profile from drawings or samples. Whether you need shiplap, tongue-and-groove, channel, or modern rainscreen cladding, we can produce precise dimensions, edge details, and finishes for a perfect fit.
We recommend durable, stable materials that can handle heat, humidity, and UV exposure—such as Thermory® thermally modified wood, Accoya® acetylated wood, or Modern Mill ACRE™ composite. Each performs exceptionally well in harsh environments while maintaining its appearance for decades.
A rainscreen system creates an air gap between the siding and the building envelope, allowing trapped moisture to escape. This design helps prevent rot, mold, and warping, while improving energy efficiency. Many of our products are ideal for rainscreen installation.
Yes. We ship and deliver materials throughout Texas and across the U.S., with next-day delivery available for many stocked items. For large or custom orders, our team coordinates logistics to ensure materials arrive on time and in excellent condition.
Yes. We stock the full range of exterior accessories so your siding system performs as intended.
Available options include:
Stainless or coated screws and clips designed for wood and composite rainscreen systems
Specialized drill bits, trim hardware, and concealed fastening options
High-quality sealers, oils, and stains formulated for exterior woods
Color-matched corner boards and trim materials
Our team can help you pair the right hardware and finish system with your chosen material — ensuring consistent aesthetics and long-term performance.
A rainscreen system is a modern cladding design that includes a small ventilation cavity between the cladding boards and the wall sheathing. This gap allows moisture to drain and air to circulate, protecting the structure from trapped humidity and water damage.
Benefits include:
Longer material lifespan and reduced maintenance
Improved building envelope performance
Better indoor air quality through moisture control
Compatibility with vertical and horizontal installations
At Mason’s Mill, our materials like Accoya®, Thermory®, and Modern Mill ACRE™ are ideal for rainscreen applications, combining dimensional stability with resistance to rot and decay.
