They manufacture all of their products from three state-of-the-art manufacturing facilities in Wellingborough Headquarters and carry full industry accreditation .

To maintain their high reputation and product quality , Astraseal fully appreciate the value of cultivating strong meaningful relationships throughout the glazing supply chain . Their relationship with Glazpart has grown since June 2022 , when the Building Regulations ( Approved Document F – ventilation ) changed .

Being a conscientious company and putting their customers first , it was no surprise , that Astraseal made sure they were ahead of the game and most importantly instantly compliant with the incoming legislation . Since the regulatory changes , their windows and doors have Glazpart ’ s award-winning Link Vent .

The ‘ Link Vent ’ range sizes include 5000 , 4000 and 2500 EQA . Equivalent Area ( EQA ) is the measure of the vents ’ airflow performance .

The vents are designed to fully comply with building regulations , Approved document F1 ( means of ventilation ).

With a clever design that is simple and user-friendly for both opening and closing - the Link Vent ’ s innovative closing action allows the closure plate to be positioned so that it reduces draughts by directing air away from occupants .

The Link Vent 4000 and 5000 closure plate is split to allow for partial ( 50 %) opening and greater ease of opening of the ventilator .

The Link Vent is available in either screw or clip in fixing types - the design eliminates the need for end caps whilst the clip fix design ( Pawl ’ s ) allows for a fast , easy vent installation .

With smart design , easy fitting , and functionality as well as a huge choice of 1000s of colours and decorative finishes , it is easy to see why Astraseal decided to use the Link Vent for its extensive range of windows and doors .

Colin Stanley , Astraseal Operations Director commented , “ We have been ordering from Glazpart for a couple of years , so when the regulations changed and came into force last year , it was a very easy decision to upgrade our trickle vent solution to the Link Vent range in order to be fully compliant . With our window and doors being installed with the Link Vent , we are applying a solution that works for installers and homeowners . It is a pleasure to be a Glazpartner and work closer with Glazpart , who can always fulfil our requirements .”
