ThermaDura shall not be liable for any loss, whether direct or consequential, economic or loss of profits or otherwise, arising directly or indirectly out of any delay in delivery of the Goods. If ThermaDura organizes the delivery using a furniture movers, the builder/customer on site has to unload the units and is responsible for having suitable equipment available.

The decision to deliver or use a third party (furniture movers), and to visit on-site or to use audio-visual means is entirely at the Thermadura’s discretion.

9.    You are responsible to accept delivery.  If you do not accept the delivery of the Goods at the arranged date, additional storage charges will be invoiced. If delivery has been arranged with ThermaDura it is your responsibility to provide easy and safe access to the delivery point and to notify ThermaDura in advance of any problems. All care will be taken to minimize damage during delivery and installation of the Goods, however ThermaDura accepts no responsibility for any damage unless it is caused by the negligence of ThermaDura’s own personnel.

It is the builders/customers responsibility to have the building site prepared for the glazing, which includes manpower to assist with lifting, and- if needed- a crane. If ThermaDura's glass- robot is to be used  (additional cost), access has to be provided, otherwise the builder has to ensure that the glass is positioned in front of the units which have to be glazed. If the glazing cannot happen upon delivery and an additional trip to the building site is required, additional travel and accommodation cost will be charged out. The builder has to ensure the site and openings are  prepared for an efficient delivery and glazing process- which includes access to all units (removal of scaffolding), staff on site for the installation of all units which have to be glazed, taping and preparation of openings, flashings, blocks or any other needed items. If the site is not prepared as required ThermaDura reserves the right to unload  the units on the roadside and it is up to the builder to organize the lifting, protection and potentially glazing at his own cost. The customer also has to assure site- access for the ThermaDura truck, ThermaDura does not allow for any cranage or hi- ab cost- that is up to the builder to organize and liase timing with ThermaDura to ensure an efficient delivery process.

ThermaDura is not responsible for any damage caused by improper installation, handling, operation or neglect by the customer or a third party. All Goods are pre-fabricated. Any damage caused by a modification made to the Goods by an external installer is the responsibility of the Customer. All instructions provided by ThermaDura must be read and understood by the installer, if you don’t understand please ring and discuss; we are here to help. All units are factory adjusted- the builder has to re-adjust the units after installation if needed. ThermaDura charges $220 plus GST per hour plus expenses and -if applicable- travel cost to review, advise on and if necessary fix issues that are or were caused by improper installation or adjustments by you or your builder/agent/etc. The decision to visit on-site or to use audio-visual means is entirely at the Thermadura’s discretion.

21.    Movement in the timber is unlikely but may occur, this is usually caused by changes in the environment and or extreme levels of heat or moisture. ThermaDura is not liable for timber movement but will attempt to rectify.
22.    Finishing products may look slightly darker or lighter in some areas. In some rare cases resin can become visible (especially North- facing, darker colours or stains) through the paint. The appearance of resin is not a fault, and does not affect weather tightness.
22.1  Any units wider than 4m might have finger-joints visible in the timber.
23.    If you live in a very harsh climate or if your home is North-facing, close to the sea, or has no protection then you may need to repaint at more regular intervals.  This is not a fault of the product.
23.1  Timber can change colour over time- the extend depends on the exposure to UV, timber species and what finish was used. This is not a product fault.
24.  At the ThermaDura factory we adjust all goods for optimal performance. Any follow up adjustment required during/after installation must be done by the builder or customer. ThermaDura will provide instructions on how to adjust the goods.  If further instructions are required via a site visit from ThermaDura or their representative, travel cost plus an hourly rate of $220 plus GSt will apply. The decision to visit on-site or to use audio-visual means is entirely at the Thermadura’s discretion.
25.   ThermaDura does not give a warranty for the finish. Where there are minor cracks or discolouration ThermaDura will supply touch up paint.
26.   In specific environmental conditions glass panes can condensate on the outside- this is a naturally occurring phenomenon which is not a fault in the glass or window.
27.   Timber windows (NatureLine- range) are glazed with silicone inside and out. The silicone has the purpose to make the units watertight. Thermadura does not supply a "dregree of smoothness" for the silicone line- inaccurancies, particularly, but not only, in the corners, are not a product fault.
28.  All blinds- internal or external- are supply only and have to be installed and programmed according to the installation instructions by the customer/builder. For motorized units a licensed electrician has to connect the units. ThermaDura offers a return to base warranty -units have to be send back by the customer to ThermaDura's office.

If the customer is in doubt ThermaDura expects the customer or builder to clarify any questions before the order confirmation will be issued .
31.  The customers, architects or builders are responsible to check the suitability of the hardware for their particular situation. All units are factory adjusted. It is up to the builder or customer to re- adjust them on site after installation. ThermaDura provides detailed adjustment instructions.

The goods have to be protected from dust, dirt, paint or anything else that might cause marks (including tradespeople). Dust and dirt can damage the surfaces of glass, paint, wood and metal. Any dust and dirt on the unit voids the warranty in relation to the surface. The customer/builder is responsible for removing the protective coverings and cleaning the units at the end of the build process. Glass stickers have to be removed 4 weeks after delivery at the latest. No tape should be used on the finished surfaces as this can cause damages.
