FAQ
How much do new aluminium doors and windows cost?
This is a difficult question to answer without detailed plans and specifications. It depends on how many aluminium doors and windows you need, what size they are, the glass and hardware you choose, and which ALTHERM® Window Systems range you want to use. The best way to obtain an accurate price for your new aluminium joinery is to request a free quote from us.
I've obtained aluminium joinery quotes from various suppliers and they're all really different – why is that?
Usually, a substantial variation in price means there is something fundamentally different between the quotes you're considering. It's really important to know whether you're comparing like with like. Do the quotes include ALL the same (or equivalent) items? Do they include flashings, sill supports, and toughened glass? Is there a warranty? Does the manufacturer provide after-sales service and maintenance? It's also worth noting that not all aluminium windows are created equal. Stronger, more substantial profiles will generally cost a bit more because they use a greater quantity of aluminium in their construction to prevent bending and buckling.
Our team are more than happy to go through your quote with you and help you understand our pricing in relation to others you have received. Please don't hesitate to get in touch with us if you'd like some assistance.
Do you make double glazed windows?
Yes. The majority of the windows and doors we supply are double glazed, in accordance with the New Zealand Building Code’s H1 Energy Efficiency clause.
Do you make uPVC windows?
We do. Our uPVC Klima Series is made specifically for New Zealand conditions and uPVC is a great option if you're looking for a thermally efficient window. To view the ALTHERM® Klima brochure, please click here
Do you make aluminium insert windows for wooden frames?
Yes. However, the viability of aluminium inserts depends heavily on the condition of the wooden window frames they're being inserted into. If you're considering inserts, please get in touch with us and a member of our team will discuss whether aluminium inserts are a suitable option for your project.
Does your joinery come with a warranty?
Yes, it does. Please visit the ALTHERM website for more information.
How long will it take for you to make my joinery?
All our aluminium joinery is made to order, which means that we fabricate each individual door and window to meet your exact requirements. As a rough guide, a job will take between four and eight weeks from the time it’s confirmed with us to the time it’s delivered to you. However, this timeframe can (and does) vary depending on order size, complexity, and the volume of other orders we have going through our factory. Our team will always make you aware of current timelines when you place your order.
Do you do the installation?
We can work in conjunction with your chosen builder and, once your new joinery is ready, deliver it on-site for them to fit, or, alternatively, put you in touch with an installer.
Do I need to buy glass separately?
No, we’ll take care of all the glazing. However, we can supply our joinery without glass, if required.
What’s a ‘thermally broken’ window/door?
If a window or door is ‘thermally broken’ it means that an insulator, designed to minimise the transmission of cold and reduce condensation, has been incorporated into its design.
ALTHERM®’s ThermalHEART™ range utilises a nylon insulator, which is placed within the aluminium profile during the fabrication process. This results in windows and doors with better thermal efficiency than those with standard double-glazing.
