Slim frame windows and patio doors

More daylight and uniform sightlines

The latest architectural trends are centred around a demand for natural daylight. Increasing numbers of homeowners have a desire to experience a feeling of light and space for their living areas. We’re currently living in an era of ‘minimal frame and maximum glass’.

Benefits of installing slim framed windows and doors in your home


They give any home a more contemporary and uncluttered look


Increased daylight improves physical and mental wellbeing


They provide an almost interrupted view of the outside


Slim frames make smaller rooms look larger


They allow more free heat from the sun into your home


VELFAC - slim frame, without compromise

The VELFAC 54mm frame increases the ratio of glass in a window, letting 25% more light in your house compared to standard alternatives, and reducing the need of artificial lightining. VELFAC windows are made of aluminium outside and wood inside, therefore they feature a slim frame design without compromising on insulation properties.

The VELFAC window system is characterised by a unique and elegant design, with simple and slim lines. All VELFAC windows and doors units feature the same appearance whether they open or not, adding a sleek, flush and uniform finish to every facade.

The VELFAC ‘floating’ frame effect is ideal for any style of home, from modern to traditional, and is achieved without compromising window performance or insulation.

VELFAC is the architects first choice

“Many of the architects I interview say VELFAC is their first choice. They particularly like the system’s slim frame and uniform sightlines which mean that every window looks the same whether triple or double glazed, opening or fixed. It’s the type of detail which can make a real difference to the overall appearance and performance of your home.”

Jason Orme, editorial director at Homebuilding & Renovating (HB&R) who chose VELFAC windows and doors for his own family home.
