As of one the UK’s leading suppliers in windows, doors and aluminium products we at Sternfenster are delighted that Double Glazing on the Web and Conservatory Online Prices have both listed us as Approved Suppliers here in the United Kingdom.

Why get your products with Sternfenster?

As Approved Suppliers for both Double Glazing on the Web and Conservatory Prices Online, we strive for nothing less than perfection with all of our ranges of windows and doors as well as continually pushing the boundaries in manufacturing high quality products.

When you shop with Sternfenster, you know you’re dealing with a business that you can trust. A family run company with over 40 years of industry experience, we pride ourselves on having a brilliant eye for detail with both the product we are supplying and our service in delivering it to you.

We have revolutionised the way uPVC windows and doors were produced here in the UK as we were the first fabricator in this country to have a seamless welder. This has allowed us to deliver our models quicker and to a higher standard than ever before. Furthermore, if you choose a Sternfenster product, you’ll have the advantage of selecting from some totally unique products, meaning you can’t get them anywhere but with our installers.

While we’re best known for our brilliant uPVC products, we’re continually trying to adapt to the times and stock some of, if not the best aluminium on the market provided to us by Smart. They are the market leaders in aluminium products and therefore whether you’re shopping for yourself or trade purposes, you know you’re getting the highest quality of product.

Keeping it in-house

What separates us from everyone else in the window and door business is that we can boast about our impressive 80,000 square foot factory here in Lincoln.

With this, we are able to produce everything at Sternfenster in house, which in turn allows us to make sure that each and every product we deliver is up to our incredibly high standards. Every detail is rigorously vetted through a host of stringent tests which results in us being able to deliver a market leading product to you.

Furthermore, we even paint all of our own products at Sternfenster in house as well – this means we can tailor all of our models to suit individual needs as well as being able to keep prices affordable. This system helps make it a win-win situation for us as an Approved Supplier and you as a homeowner.
