Updated on

Google Synseal Reviews or Warmcore Reviews and the results are not positive.  A visit to the Synseal Group Reviews on Trustpilot reveals 93% rated as ‘bad’ with just 7% rated as ‘average’. Homeowners contacting our website also ask if they should steer away from Synseal’s products after finding negative Synseal and Warmcore reviews online.

This article addresses some of the negative reviews and importantly, also explains why Synseal, in many cases, is unfairly criticised. Read our full review of Synseal Warmcore doors for in-depth information too.

Synseal offers the Warmcore suite of bifolding doors, sliding door and windows.

Information and advice about Synseal Reviews online.

Most of the negative comments centre around the Warmcore range of bifolding doors. On the one hand,  the Synseal reviews on Trustpilot are small in number, compared to over 500 reviews for Origin’s range of windows and doors. On the other hand, some of these reviews are so bad, we think they could unfairly impact sales of the Warmcore product.

Furthermore, many excellent businesses fabricate and install Warmcore are potentially losing out on good business as a result of these reviews.  Even more pertinent is some companies set up entirely on the back of the Warmcore product when it launched in 2015.  Synseal is a substantial systems company with some industry leading brands under its belt.

Moreover, is the Warmcore product good and are the negative Warmcore reviews and Synseal complaints justified?

The Warmcore System is a quality, fit-for-purpose product.

First of all, Warmcore remains fit-for-purpose and not sub-standard.  Our comprehensive review of the Warmcore bifolding door explains more about Synseal’s product.  The Warmcore system is an innovative hybrid system using a combination of a big PVCu thermal core with aluminium on the inside and outside faces.  As a system and as a concept, Warmcore is good.  However, like all door and window systems, it comes with certain characteristics within its design, manufacturing and installation.

The substantial thermal core provides excellent U-Values with standard glass units, where other systems need enhanced glass or triple glazing.  However, this is a PVCu core and entirely different from the polyamide core used in most aluminium systems.  It is also not as forgiving as polyamide meaning extra care in both fabrication and installation.

When Warmcore is incorrectly made and incorrectly fitted, the product is potentially problematic, such as bowed door sashes and even the aluminium capping coming off the thermal core.  We must stress this is not a design fault.  Any product not made to a good standard risks problems as a result.

Above all, the extrusions, thermal core, powder coating, components and hardware all meet or exceed current British and European Standards. Warmcore also meets Secured by Design for security as well as the relevant classifications for air wind and water and a 10 year guarantee.

Understanding the negative Synseal Reviews.

With many years experience in the fabrication and installation of windows and doors, we can see that the negative reviews around Synseal are seemingly as a result of incorrect fabrication and poor installation.  The Warmcore system itself is not entirely to blame.

Synseal, to their credit, responds to these reviews and stresses they do not manufacture the product. Synseals only designs and supplies the materials. It is Synseal’s network of nationwide fabricators making Warmcore. Also to their credit is Synseal acknowledging early versions of Warmcore had issues and these are now addressed.

Just like every other major systems company Synseal’s role is supplying bar lengths and accessories to their fabricators. They also provide training, tooling and overall support.  Schuco, Reynaers, Smart Systems, Aluk, SAPA Building Systems for aluminium work in exactly the same way.  Liniar, Rehau, Kommerling, Eurocell, Duraflex and others with PVCu also work in exactly the same way.

We can also tell you that every systems company like the aforementioned invests substantial sums in bringing a product to market.  Design, testing, independent certification, training and supply is an expensive and complicated process.  No systems company sets out to design a bad product. And Warmcore is not a bad product.

Furthermore, as with any new product, manufacturers and installers regularly working with it, provide feedback to the systems company. As a result, they continually improve their product throughout its life cycle.  Assuming Synseal supplies correctly extruded profiles to their fabricators, it is fabricators and installers apparently letting the company down from the online reviews.

Synseal works just like most major systems companies.

There are also comments relating to Synseal charging customers for site visits to inspect their product.  We can tell you they are not unique in this and other systems companies also charge.  The role of the systems company in the overall supply chain is rarely dealing with homeowners directly.  In these reviews, Synseal does clarify their role and how they work.

So we stress again, that the negative Synseal reviews are putting the blame on the designer of the product and the raw material supplier.  This is unfair when the negative experiences are down factors, many of which are clearly outside of Synseal’s direct control.  However, it does appear that Synseal needs to improve how it supplies Warmcore materials.

We understand that Synseal do fabricate some of their products as well, so for balance presume some of the negative reviews relate to doors coming out of the Synseal factory.

Our advice to Synseal is this:

  1. Get actively involved in not only assessing some of their fabricators better but also work closely with the homeowners to achieve a satisfactory conclusion.
  2. Provide better training to fabricators and installers of Warmcore.  Many of the problems would never arise with a correctly made and fitted product.
  3. Synseal must encourage these customers to leave further reviews once problems are fully resolved and the customer is happy.

Alufold Warmcore bifolds offer unique features you won’t find on other products.

Looking to buy Warmcore? Choose your fabricator and installer carefully.

Above all, do your research and check out who makes your Warmcore doors.  A good Warmcore supplier makes a fine product or sources it from a good fabricator. We stress again, Warmcore, like any other door and window, needs precise fabrication and correct installation.

The door and window industry is a competitive space with many different ways to buy windows and doors. There are some fabricators selling at rock bottom prices and reflected in the quality.  There are also excellent fabricators making outstanding products of the highest quality with a 1st-class service all round. Therefore, any product is only as good a who makes and fits it.  Importantly, the professional Warmcore fabricators and installers do not experience the issues raised by the negative Synseal reviews.

This is where we can help you.  Use our contact form on this page and get in touch.  We can put you in touch with Warmcore fabricators or suppliers that not only fully understand Warmcore, but they also make it well and know how to fix it.

One such Warmcore fabricator and installer working nationwide is Aluhaus in Nottingham.  Not only do Aluhaus make Warmcore well, but they’ve also re-engineered and enhanced it providing even more features and benefits over the standard Warmcore. 

Synseals’s Warmcore range is a good product and the negative Synseal reviews should not frighten you to death about the consequences of buying it. Contact us for further information, advice or where to buy.

I contacted Nick @ ATS for guidance on what aluminium sliding door systems would be suitable for an opening in an extension that is going to be both wide and tall. He came back really quickly with very detailed and incredibly helpful advice. He is clearly extremely knowledgeable about the systems on the market and their respective features and capabilities. If you’re feeling a bit lost by the overwhelming range of choices out there, I’d definitely recommend contacting him.

After a lot of research to find doors that would meet our unusual size requirements and feeling increasingly uncertain about the best way to spend our small budget, I stumbled on the ATS website, and I'm so glad I did! I contacted ATS to request advice and Nick promptly replied with a wealth of information, providing us with options and relevant contact details. I only wish I'd found them sooner!

I've been so confused about how to achieve the look I'm after, and going round in circles with various window/door companies, trying to get away from the huge chunks of plastic currently around my windows. I didn't expect an email to a company found through a Google search to really help - but I was desperate, so I tried. I'm SO glad I did. Finally I have clear explanations from ATS of where I've been going wrong, exactly what I'm looking for, and a list of local companies that might be able to provide it! The response has excelled my expectations and I feel as if I'm finally inching closer to a home with which I'll be happy and comfortable: thank you.

It is rare that I write reviews, however after my very positive communication with Nick - enquiring about suitable slim sash aluminium windows for my project, I felt that a review was definitely warranted. I can reinforce the many positive reviews posted so far, Nick was very quick to respond, providing comprehensive detail, with excellent independent advice.In summary, great service, thank you Nick.

I dropped Nick at Aluminium Trade Supply an email re high security slim sightline bi-folds and their alternatives and he responded that quickly (and so comprehensively) that I felt bad I’d not paid him for his time!Nick Sir your product knowledge is outstanding and you are providing a level of service that goes wayyyy above and beyond expectations. I’ll definitely make sure I mention Aluminium Trade Supply to anyone I encounter looking for a fenestration solution 🙏🏼

We are looking to replace some old UPVC patios doors with aluminium ones. The ATS website is a great source of advice in an area where clear information is sorely lacking. Having used the website, I then followed this up with a number of specific questions relating to our search, and Nick came back very quickly with clear, detailed and very useful advice.I have been very impressed with both the website and with Nick's advice. My only regret is that I didn't come across ATS before replacing various windows in 2021 - I'm sure it would have saved me a lot of grief and money! Thanks again Nick.

My experience with this firm was exceptionally good and this is notalways the case as a female, dipping a toe into technical waters.I was spoken too with courtesy and at a level that helped me consolidate what was needed .On top of that I was given a list of companies and places where I could obtain the type of product I needed.I could not thank them enough and would certainly go there again and reccommend others do too.
