Great looks and excellent performance: Integral | Epwin Group
Epwin Window Systems have launched their new intelligently designed Integral bifold door. Gerald Allen, Marketing Manager of Epwin Window Systems explains: “Bifold doors are a booming sector but to date there has always been a problem. Aluminium bifold doors simply don’t suite with existing PVC-U window systems, but our new Integral bifold door solves this problem.”
Integral bifolds are the ideal choice where existing PVC-U glazing is in place, or where the crisp lines of other aluminium bifolds have an aesthetic that’s simply too clinical. Integral is different, but it’s more than just a perfect match for PVC-U – it’s a genuine, proven and high-performing aluminium system.
The external frame and sash upstand are bevelled to match the leading PVC-U systems. For a contemporary look, there is the alternative of a sash with a square-shaped upstand. All doors are internally glazed and feature a choice of labour saving bevelled or sculptured PVC-U beads to complement the style of a property’s windows. And, where clean, modern lines are required, there’s a smart, square aluminium bead. A choice of foil colours and woodgrain finishes adds to the appeal.
Integral bifolds can be glazed from 28mm to 44mm triple glazing delivering exceptional thermal efficiency with a U value as low as 1.1W/m²K. They also meet all security requirements – they are PAS 24 accredited up to 1000mm wide x 2400mm high, meet Secured by Design standards and are Document Q approved.
Superior and long lasting
Bifolding doors need to be strong and resilient. Aluminium (with its lightweight handling and strength) is the ideal material. Integral bifolds utilise aluminium profiles engineered specifically for the job. Every single component of an Integral bifolding door has been selected for its quality and long-term performance. From the security hinges to the low-profile gaskets that keep the water outside. Integral’s double hinge fixings, stainless-steel tracks and rollers confer the additional rigidity necessary for PAS 24 accreditation and high-use repeated opening.
Secure and Protecting
Integral bifolding doors include advanced multipoint locking to the main access door. Robust shoot bolts secure secondary doors and folding leaves to the top and bottom tracks. Anti-lift systems prevent leaves being lifted from the frame. Combined with superb hinges, tamper-proof lock cylinders and toughened or laminated glass, Integral bifolds can pass the most stringent security tests and meet the requirements of both Secured by Design and Approved Document Q.
Integral bifolds have been tested to withstand onslaughts by the wind and the rain. A combination of seals, glazing gaskets and precision manufacturing keeps your home comfortable and dry. To ensure adequate ventilation and to meet building regulations, we can incorporate unobtrusive trickle vents which help to manage condensation in well-insulated homes.
