Latest news

Seals are wear parts – now is the time to replace them!

Autumn is the time to check seals before old, porous profiles let draughts in through leaky doors and windows. Only seals in good working order prevent heat and valuable energy from being lost. We help you prepare for seasonal demand – whether you are a distributor, joinery business or construction company! With more than 1.2 million metres of replacement seals in stock, our warehouse is well supplied. Thousands of profiles, numerous colours and a wide choice of materials: order everything you and your customers need to get ready for autumn and winter from the GfA online shop.

GfA keeps its finger on the pulse of the industry at Nordtreff Fenster-Fassade (NFF)

Almost 20 exhibitors, more than 220 participants – and GfA right in the middle of it all! Managing Director and “sealologist” Nico Czok and Project Manager Patrick Witthöft took on a self-imposed challenge at this lively industry event: anyone who brought any seal to the GfA stand received identification of the profile within a maximum of 90 seconds. A suitable offer from the GfA shop was provided on the spot – along with opportunities to exchange ideas with colleagues and key players in the market. With our customers in mind, we are building a network of professionals that enables us to find solutions to even the trickiest challenges. And by keeping our ear to the market, we stay up to date for you!
