How We Operate

Fenestra’s structure is rooted in the cooperative model that fosters our wealth of experience, and knowledge to create committee-driven selection processes. This synergy enables Fenestra to methodically choose the best suppliers for our network.

Frequently Asked Questions

Fenestra Member-Ownership is for window and door fabricators across Canada and is by invitation only.

No, Fenestra believes in freedom of choice in who fabricators buy from. Members are encouraged and rewarded but are not required to switch all their purchases through to the Co-op’s participating Supplier Partners.

Existing members may submit new supplier suggestions and sponsor them at any time.  The Supplier Selection Committee, a small number of Member-Owners, will then evaluate the supplier based on a wide set of criteria which includes factors from pricing, rebates, terms, return policies, service levels, and the product brand acceptance.

Rebates are a powerful tool for both the Supplier Partners and the Members. Suppliers like rebates for two main reasons;

  • firstly, they protect the “street price” of their products
  • secondly, they can structure the rebates as such that they only pay for member performance and loyalty


The Members benefit from rebates because they are able to protect negotiated pricing and the margins made on the sale of the products. Then, at the end of the year the rebate check comes in and goes straight to the bottom line!

Only the Supplier Selection Committee will know the full terms of the rebate programs. Strict enforcement of Fenestra Supplier Partner confidentiality enables suppliers to offer better overall pricing only to Fenestra Members without the risk of competitors or other of the supplier’s non-buying group customers knowing and saying “me too!”

Rebates are returned to each Member proportionally as they have been earned.  For example, if Member A purchased 5% of the total Group purchases they would receive the same 5% of the earned rebates for each supplier program. Fenestra’s unique central billing and payment model allows line item tracking and a complete audit trail to ensure each member receives their portion of any earned rebates.

Fenestra is a 100% Member-Owned Purchasing Co-operative. Each Member-Owner holds one share only. One share – one vote ensures all Member- Owners have a voice in their Co-op. The Co-operative model returns profits (earned rebates), in direct proportion to the purchasing participation of each Member.

The Co-op is managed under contract by LBMX Inc., utilizing a dedicated General Manager, as well as support staff, a board of directors, and member committees are all utilized to ensure the Co-operative meets its objectives.

Each Fenestra Member is required to meet credit criteria. In addition, a third-party Accounts Receivable insurance is used to greatly reduce the impact of any default. In the rare occasions where a Member default has occurred, Fenestra has triggered the AR insurance and the Supplier payment has been paid within 90 days. In all cases of default to date, our Supplier Partners have received payment on 100% of their invoices processed through the Co-op.

Fabricator Member-Owners:

  • A one-time $1,500 Setup Fee on Fenestra’s billing platform.
  • An annual $3,500 Membership Fee.
  • A $1 Shareholder buy-in.
