Do I need special tools to work with Millennium Decking?

Millennium Decking works like wood and in some ways works easier. It can be cut, drilled and routed using regular tools. When cutting, use a 24 tooth carbide tipped blade or finer.

What types of fasteners are recommended for Millennium Decking?

Screws are determined by the structure to which the decking is being attached; usually lumber, but some times aluminum channel as with some dock kits. Ask your dealer which screws are recommended (hot dipped galvanized, stainless steel, ceramic coated or other) for the structural material you are working with, and conditions such as exposure to salt water.

Because we use wood flour rather than wood strands or wood chips, there is no grain or orientation in the material. Drilling pilot holes is generally not required. See the Millennium Decking Installation Guide for further details on Screws & Glues.

Does Millennium Decking come with a warranty?

Millennium Decking has a 20 Year Limited NON PRO-RATED Warranty.
see Product Warranty

Can Millennium Decking be used for posts or joists?

While Millennium Decking is tough and durable, it is not intended for use as a load bearing post, joist or other primary load bearing part of a structure. The fascia board is used as cladding for rim joists, posts and backs of stair risers.

What spacing do I use for my deck joists?

We recommend that you install joists on 16" centers, 12” centers for stairs.

Can Millennium be installed over existing decking or plywood?

No. Due to the fact that Millennium expands and contracts less than wood and plywood, doing so would compromise its tongue and groove aspect. Screwing directly to the joists is the only recommended installation technique. Failure to comply with this will void Millennium's 20 year warranty.

What will water do to Millennium Decking?

When wood absorbs water, it will swell and as wood dries out, it will shrink. Cracking, splitting and rotting can follow.This generally does not occur with Millennium Decking (in documented history) as the PVC fully surrounds (encapsulates) the wood flour. Also, because we use wood flour rather than wood strands or wood chips, there are no strands that connect or contact each other. Moisture will not enter the boards through capillary or wicking action along the wood fiber.

Can you make Millennium Decking a waterproof membrane?

No. Millennium Decking is not intended to be a waterproof membrane and should not be used where one is required. Although it is a tight tongue and groove design, water can still get between the boards.

Can Millennium Decking be painted or stained?

No. Millennium Decking absorbs very little - so paint or stain will not penetrate.

How do I care for my Millennium Deck?

All you need to do is clean your deck periodically. A soapy mop and a garden hose work well! A low-pressure power washer can also be used.

How should I transport and store Millennium Decking before installation?

Millennium Decking is weighted similarly to wood but is more flexible. When moving boards, lift from two balanced midpoints. Store on a flat surface. Cover if stored outdoors for an extended period of time before installation.

How does Millennium Decking react to hot and cold weather conditions?

Because of its formulation and unique production process, Millennium Decking has a low coefficient of thermal expansion and contraction. (the amount a material expands or contracts when heated or cooled). The coefficient for Millennium Decking is very close to wood so the decking expands and contracts at a rate similar to the wood structure. This is preferable to materials having either higher or lower coefficients as allowances have to be made for dissimilar movement of differing materials.

Will insects damage Millennium Decking?

Millennium Decking is highly resistant to insect attacks as the wood fibers are encapsulated in the PVC creating a barrier to insects.

Will Millennium Decking fade or change color?

Minimal product fading will occur, comparable to PVC siding; also slight color variation may be apparent from board to board as it is a wood based product.
