Wood Clad Windows and Doors
Low-maintenance aluminum or vinyl outside, real wood warmth inside: one ordered unit, specified from your plans and delivered to your San Diego site.
Chapter 01
Two Materials, One Unit
Wood clad is exactly what the name says: a wood interior wrapped in an exterior shell, usually aluminum or vinyl, bonded into a single unit rather than two materials fastened together after the fact. The exterior shell takes the weather. The wood interior takes the room. Marvin and Andersen, two of the six brands we carry, both build wood clad lines this way, in awning, casement, double and single hung, gliding and picture configurations depending on the brand.
The appeal is straightforward once you see it on a real job: the low-maintenance outside of an aluminum or vinyl frame, paired with the warm, customizable interior of real wood, in one ordered unit rather than a compromise between the two. It is not a hybrid in the sense of splitting the difference. It does both jobs fully, each on its own side of the frame.

Who Wood Clad Is Really For
Wood clad shows up most on a specific kind of project: a remodel or a build where the owner wants the warmth of a wood interior but does not want the repainting and resealing schedule a full wood exterior asks for. That is a common brief, and it is the most useful way to think about who wood clad is for versus who should look at real wood instead.
If the honest answer to how much upkeep you want to do on this window in ten years is none, wood clad is usually the better call over full wood, and we will say so at the counter rather than sell the more expensive material because it happens to be in the showroom. If you want the exterior to weather and age like a natural material, full wood earns its place instead.
Chapter 03
Matching Interior Species to the Rest of Your Millwork
Because the interior face is real wood, it can be finished to match whatever millwork is already in the room: door casings, baseboards, cabinetry. That is the actual value behind a customizable wood interior, not a phrase on a spec sheet but a real decision that determines whether a new window reads as part of the room or as something bolted on afterward.
We have seen both outcomes on real jobs. Walnut interiors chosen specifically to match existing walnut millwork read as if the window had always been there. A mismatched species or finish, chosen without walking through the rest of the room first, reads as new for years. Bring us a sample of your existing trim, or a photo of the room, before the order goes in.
What to Check at Delivery
We supply and deliver, we do not run the install crew, so what happens the moment a wood clad order lands on site matters. Check the exterior shell for shipping damage before your installer starts working, check that the interior wood face has no cracking or finish damage, and confirm the hardware finish matches what was actually ordered rather than what a packing slip claims was substituted.
Those three checks catch nearly everything that can go wrong between our counter and your installer's hands. If anything looks off, call us before installation starts, not after. It is a far easier fix on an uninstalled unit than on one already in the rough opening. Manufacturer's warranties are available on everything we carry, and we will help work through a warranty question the same way we help with everything else.

Same opening, two jobs
What the Street Sees, What the Room Feels
A wood clad opening is doing two different jobs at once, and it looks like it. From the street or the yard, the exterior shell, aluminum or vinyl, faces the weather and does not ask for repainting or resealing on any real schedule. Walk inside the same opening and the exterior disappears entirely: what you see and touch is the wood interior, finished to match the room around it. These two photos are the same product line, one exterior and one interior, on two different Builder’s Window Supply deliveries.
