COMPARE QUOTATIONS
How to Compare Window & Door Quotations
Two quotations can describe the same opening and still include different products or services. Compare the configuration and scope line by line before comparing the final totals.
For importers, distributors, contractors, project buyers and homeowners planning custom aluminum windows.
FAQ
Before we begin.
A few things to know before you start your window and door inquiry.
Can I compare prices per square meter?
A unit-area figure may be useful only when its calculation basis and included configuration are clear. Different quantities, opening mechanisms, glass and hardware can make two such figures misleading. Also compare the total for the same opening schedule and delivery scope.
Is a thicker profile automatically a better product?
Profile wall thickness is one specification, not a complete measure of system performance. The frame design, dimensions, glazing, hardware and relevant evidence need to be considered together. Compare the configuration required by your project instead of ranking systems by one number.
Can I compare two different glass build-ups as equivalent?
Not solely because both are described as double glazing. Check the glass thicknesses, treatments, coatings, cavity and other specified details. If the project requires a particular performance value, compare the supporting information for the complete proposed configuration.
Why can a lower product total lead to a higher final cost?
The quoted scope may differ. Packing, freight, import responsibilities, installation or other items may be excluded from one proposal and included in another. List these differences before treating the totals as directly comparable.
Are all quoted U-values directly comparable?
First check whether the value describes glass or the complete window or door, the units used, and the method and configuration behind it. Values with different bases should not be ranked as if they describe the same product.
What if a supplier states “certified” without a document reference?
Ask which certification or report is being cited and which product configuration it covers. Keep the reference with the proposal so the claimed evidence can be compared with the actual opening type, glass and dimensions.
How should I compare a revised quotation?
Identify the revision and list what changed in the configuration or scope. Compare the revised line items against the latest schedule, rather than carrying forward assumptions from a previous quote. Confirm unresolved differences before selecting a proposal.
