When you spend $10,000 to $100,000 on a door and it warps, can you fix it? No.
It may be a beautifully and skillfully handmade door, but if it is warped, it fails to function as a door to any level of satisfaction.
These expensive doors are made with solid materials or core substrate material which is the weakest link. The core of the door determines the weight, strength, and long term performance of the door. Only doors with patented and patent-pending Sing Core technology inside can be guaranteed not to warp or fail regardless of size, exterior surface material used, or style of door for 50 years.
“We’ve switched from using LVL door core to Sing Core and no longer have to worry about warped doors.”
While LVL and wood-based door cores are fine for standard sized doors, these are not practical for large doors because they increase the weight of the door significantly making it more apt to fail, expensive to handle, maintain, and even potentially dangerous.
This is why the top door companies, millworks, and custom door manufacturers rely on Sing Core delivering the best door substrate enabling them to warranty wooden and large doors.
Would you settle for a 1-year warranty?
Most doors come with the standard 1 year warranty (large doors may only carry a 30-day warranty, or more commonly, are exempt from any warranty at all) because, as is well known and they say in the industry,
“All large size wood doors warp,”
unless they have Sing Core inside.
