Wholesale Windows and Doors

The cheapest variant will be non-operable windows or fixed. This is because of the lack of moving mechanisms or parts since there is little cost reduction you can do on the frame and glass without sacrificing too much on quality.

As for the operable types, double-hung windows are usually the least expensive with a frame made of vinyl. Little to no e-coating and double pane glass are other additional ways you can cut on your costs.

In terms of design, you will have to pick from a pre-defined style with little to no customization.

Costs are highly variable, depending on many factors like:

• Size
• Country
• Manufacturer
• Design
• Frame material
• Glass
• Thermal brakes
• Finish

To get the most accurate idea, you can make a free quotation to most manufacturers and they will come back to you with a price.

Pros

• Lower costs with the same quality
• Wide variety of designs to choose from
• Good service
• High and quick manufacturing output

Cons

• Communication may be difficult in case they don’t have people you can contact in English
• Shipping may be expensive and it will take time
• Quality may be poor in some cases, depending on the seriousness of the manufacturer

The simple answer is that buying from manufacturers directly is generally more profitable. Firstly, in terms of price, buying directly from the manufacturers cuts out the middle man, and therefore additional costs or fees.

Regarding customization, talking with the people doing the actual manufacturing will give you more unique design options. You can even take part or observe the step by step process to make sure you will receive exactly the product you want.

In case you are already in China, you can simply visit some of the more known manufacturers in the industry or attend fares organized by them. If you are, however, not in China or cannot travel there, you can hire a professional sourcing agent to handle your sourcing requirements.

Look for one who has excellent communication skills to make sure they can transmit your exact preferences to the supplier.

Energy efficiency

Talk with your supplier about any energy certifications they may possess. As a general rule, triple-pane glass with insulating glass in-between is the best option regarding thermal efficiency.

Amount of maintenance required

Ideally, you would want to conduct as little maintenance as possible, but this is dependent on the material. Vinyl and aluminum frames do not deteriorate over time, so they won’t need to be repaired unless a serious accident occurs. For hardware, stainless steel is the best choice regarding long-term usage.

Warranty

Many years warranty is usually a mark of expert craftsmanship. If your manufacturer can offer 25+ years of warranty, that means they are confident in the quality of the product and so should you.

Security

While large glass panels provide a clear view to the outside, it also provides additional entry points into your home and a weak point against the elements. Consider stronger glass if you live in an environment with extreme weather.

Appearance

This is usually provided by the frame material. If you want to go for that traditional, natural look, you may want to consider timber. Otherwise, more modern options include aluminium and uPVC.

Glazing

Double glazed glass is a better option for keeping your home cooler during summer and retain the heat during winter. Even if the single glazed option may be cheaper, long-term energy costs are sure to make up for the additional costs of double-glazed glass.

Material

A balance between personal taste and need should be achieved here. If you like the natural look of wood but you live in an environment with high humidity, this may not be the best option, and you may instead opt for aluminium or uPVC. Durability and sleekness for aluminium, the natural beauty of wood and the balance between the two for uPVC is how manufacturers may describe those materials to you.

Reviews

While word of mouth may be the best compliment a company can get, online reviews are a good way of creating an opinion based on other people’s experiences. Accidents and mistakes can, of course, happen to anyone, so that may explain some negative reviews, but you should look for whether the reviews are either overall positive or negative.

Certification

Manufacturers will not hesitate to show off a certification badge on their website if they have one because they know this is something customers look for. If their products are subjected to inspections from authorized bodies and are approved, that is usually a mark of good craftsmanship and seriousness.

Partners

Look at the partners of the company you are interested in. If you see any big names, that is an encouraging factor. No company would intentionally be associated or do business with others that are not serious or may damage their reputation.
