Buying & delivery
Questions before you order.
What information is needed for a quotation?
Send the delivery country and city, opening width and height, quantities and preferred opening method. Include glass, finish and hardware requirements where available. A window schedule or marked-up drawing helps identify each opening.
Is there a minimum order quantity?
Send your quantity for each product and finish. Minimum quantities and setup costs are reviewed for the selected system; confirm these in the quotation before ordering.
Can I review a sample first?
Ask about a finish sample, profile section or complete sample unit. Availability, sample charges, freight and approval arrangements must be agreed before a sample is prepared.
How are configurations approved?
Confirm the opening schedule, dimensions, glass build-up, finish and hardware in writing. The agreed quotation and drawings define the order; catalogue photographs are appearance references, not a substitute for an approved specification.
How long will production take?
Request an order-specific production schedule after the system, quantities and approval requirements are clear. Confirm the production start conditions, estimated dispatch date and transit allowance separately.
How are products packed and delivered?
Discuss protection, crate requirements, opening labels and unloading arrangements with the quotation. Confirm the delivery destination and responsibilities for freight, customs and unloading in the written order.
Which payment terms apply?
Payment stages and currency are specified in the written quotation and order confirmation. Independently verify any request to change bank details through an established contact channel.
What about installation and after-sales support?
Confirm available installation guidance, spare parts and warranty scope for your system before ordering. Local installation, site measurements and any on-site service must be expressly included if required.
