Protect Furring Strips (1 1/2″ x 5/16″ x 8′)
Quarrix ProTect Furring Strips in the 1 1/2″ x 5/16″ size offer a lightweight yet durable option for vented siding projects. Best for small to medium exterior framing where airflow behind cladding is essential. Features include multiple sizes, breathable backing, and strong construction resistant to warping, splitting, and mold. Pick this if you want a slim spacer that minimizes visible profile while maximizing moisture escape. Caution: ensure consistent moisture exposure ratings align with your climate and cladding material.
Protect Furring Strips (1 1/2″ x 1/2″ x 8′)
This 1 1/2″ x 1/2″ variant provides a balanced option between slim and sturdy, suitable for vertical or horizontal siding layouts. It shares the breathable, warp-resistant design that helps your exterior cladding stay dry and aligned. Best for projects where a mid-range thickness is preferred. Limitation: may require additional framing for particularly heavy cladding materials.
Protect Furring Strips (1 1/2″ x 3/4″ x 8′)
This 1 1/2″ x 3/4″ size provides extra rigidity for heavier sidings or larger panels. It remains breathable and resistant to warping and mold. Best for moderate-load exterior cladding. Choose this if you need a thicker strip without increasing profile too much. Caution: verify compatibility with existing framing and weather barrier systems.
Protect Furring Strips (3″ x 1/2″ x 8′)
Thicker 3″ width provides a robust backing behind heavier exterior panels while maintaining a 1/2″ thickness for spacing. Best for heavy-duty siding or where additional air gap is beneficial. Better for projects where rigidity is prioritized over a slim profile. Limitation: wider strips may affect overall wall cavity space and require careful planning for trim fit.
Madison Mill American Ash Wood Strips 1/2″ x 1-1/2″ x 12″
Premium American ash wood strips, unfinished with light tone and straight grain. Best for finish carpentry, trim work, or projects where a natural wood look is desired. The strips have true-to-size dimensions and provide strong yet lightweight performance for shaping and detailing. Limitation: wood is sensitive to moisture; proper sealing and finish are recommended to prevent warping in damp environments.
Buying Guide: Key Considerations For 1/2 Inch Furring Strips
What size should you choose? The 1/2″ thickness is common for spacer purposes, but width (1-1/2″ or 3/4″ or 5/16″) and length (8′ or 12″) affect rigidity, air flow, and application. For exterior cladding, prioritize breathable, warp-resistant materials like vinyl-backed or treated wood to prevent moisture buildup. For interior trim, consider wood strips that machine cleanly and accept staining or finishing well. Durability, moisture resistance, and compatibility with your cladding or substrate are the main decision drivers.
Material choice matters. Metal or engineered composites offer excellent moisture resistance and straightness; natural wood provides ease of finishing and a traditional look but requires sealing for humidity. For DIY projects, select a size that aligns with standard siding gaps and framing dimensions to avoid last-minute cutting or rework.
Installation considerations. Ensure your framing is plumb and square before applying furring strips. Use corrosion-resistant fasteners suitable for the strip material and climate. If using breathable backers, confirm the chosen cladding can breathe and that the air gap is sufficient to prevent moisture entrapment. In damp climates, select strips with higher mold resistance and backing that promotes airflow.
Frequently Asked Questions
- What is a furring strip used for? It creates a spacer and ventilation gap behind cladding to reduce moisture damage and ensure a true, straight surface for siding or trim.
- Which size is best for exterior siding? A width that provides adequate support without adding excessive profile; typical projects use 1-1/2″ widths with varying heights based on moisture and substrate.
- Are wood furring strips suitable for wet climates? Yes, but they require proper sealing and finishing to prevent warping and mold; consider treated wood or alternative moisture-resistant materials.
- Can I mix strip sizes in a project? Yes, for different sections or load requirements, but plan spacing and fasteners to maintain even alignment and airflow.
- What maintenance do furring strips need? Regular inspection for warping, mold, or splitting, and resealing or repainting as needed in exposed exterior areas.
- Are the Quarrix strips better than traditional wood? Quarrix strips offer breathable, moisture-friendly backings with warp and mold resistance, which can be advantageous in damp climates.
