Letter to the Editor - Facts not fiction!


Kevin Warner, profine UK

Dear Ian

As one of the world’s foremost innovators of PVCu window and door systems, we place a great emphasis on product design, performance and testing. When KÖMMERLING make product claims, we do so with considered research and understanding, as we have done so with the launch of our new System 76 platform.

However, I’m again disappointed to read falsehoods in advertising, most recently with claims for patio door security. Our PremiLine Pro, we believe, was the first PAS 24 tested and Secured by Design accredited PVCu patio door that didn’t rely on plunge bolts and that met the requirements of the Lifetime Homes initiative. We have PAS 24 and Secured by Design on 2, 3 and 4 pane variants and have carried out physical testing on these configurations, impressively with just a single door combination in each instance. It’s also a patent protected design, thanks to the clever locking mechanism at the interlock.

The increased promotion of U-values in the UK market also needs to be carefully considered. Rough estimates of performance and theoretical upgrades to profiles is a weak excuse, as U-values (or Uf values and Uw values to be accurate) should be based on independent testing as we have done so through ift Rosenheim. Our KÖMMERLING System 76 Passivhaus variant for example, can achieve a Uw value of 0.69 W/(m2K) and we have the written evidence to prove that.

Ultimately, as an industry we must get our own house in order and it’s up to both the supply chain and marketing agencies to ensure that all promotional content is true, fair and accurate. So please let’s stick with the facts, not fiction.

Yours sincerely

Kevin Warner
