Windows and Rooflights

Polyvision Windows

Polyplastic offers a wide range of windows in standard dimensions. Windows are available as top hung or framed versions as fixed, opening or sliding. Different screen prints, frame colours and acrylic colours provide the final bespoke look for the perfect look to your caravan or motorhome. 

Our Polyvision windows use a sealing rubber that is a supple, frost-proof compound that seals directly onto the acrylic, meaning there is no hinge step to cope with. 

The windows offer an increased visibility due to the lack of blind infringement into the aperture, giving an increased clear field of vision and enabling smaller aperture. 

These windows are also easy and quick to fit as they are provided fully assembled. 

You can discover our wide range of Polyvision windows at our retailers. Find your nearest retailer here:

Heki Rooflight

Our range of Heki Rooflights offer first-class quality with durability and high operating convenience.  

All models are equipped with roller blinds and fly screens, and some also feature integrated lighting. 

For caravans we offer a rooflight with an inner frame with darkening roller blind and fly screen, simultaneously and continuously adjustable. The double pleated Duette honeycomb roller blind guarantees excellent thermal insulation. To round it all off, the rooflight has pneumatic springs for convenient roof light opening. 

For motorhomes and caravans, we can supply many products, including a pleated black gauze fly screen and two integrated lights for low-light ambience. Fly screen and roller blinds are fitted from the side and can be adjusted as desired.  

Our range of bathroom rooflights include the Micro Heki. Designed for a roof opening of 280x280mm, it is the smallest rooflight in the Dometic range. Its elegant inner frame integrates a single pleated optional darkening blind and a fly screen, which can be adjusted separately as required.

Windows, Catches and Stays

We stock various brands for our windows, catches and stays, so you can pick the one that suits your vehicle best. 

All polyplastic window fittings are available in either a standard screw-on fitting or the more recent variant of the slide-on Polyfix design. The slide-on ‘Polyfix’ design is easily identified by the deep groove moulded into the back of the window fitting, which slides over the adapter fitted to the window. 

We also supply Dometic SEITZ S4 Hinged Windows. These have repeatedly proven to be a great window for motorhomes and caravans with telescopic hinges for convenient ventilation, built-in darkening roller blinds and fly screens. 

The Dometic SEITZ S4 Sliding Window provides a classic model with acrylic glass panes and locking system. The front windowpane is adjustable and the rear pane is fixed. External and internal frames are screwed together from the inside and provide durable and effective insulation.
