Essential Extras

We highly recommend choosing one of the following products with your purchase of the Roto WDF R75 K AL 13/14 White PVC Top-Third Roof Window 134x140cm
Product Description


Contrary to the standard roof windows on the market with centre pivot openings in the middle of the window, Designo R7 is a top-third pivot roof window that can be opened outwards to 38°, with one handle - accessible to everyone - at the bottom of the sash.

The Roto top-third pivot roof window is supplied with the required brackets already pre-fitted, therefore making installation both easier and quicker. You simply take the window straight out of the box, and into the roof. 

The pre-fitted insulation collar helps to reduce thermal bridges and also includes the vapour barrier as standard for high air-permeability. A double seal in EPDM rubber also ensures air tightness requirements.

Fantastic product - excellent quality, nice look and feel and fab price. Best thing is you don't hit your head due to 3/4 pivot position

This is a great window which doesn't protrude into the room when open. Our builder was not familiar with the type and make, but the instructions and his experience meant that it was fitted easily. I would recommend this product.
