The Ultimate Rose

The 35mm midrail in Roseview's award-winning Ultimate Rose sash window is the thinnest on the market. It is 10mm narrower than our typical Heritage rail, giving it the appearance of being made out of a single, solid piece of wood. In order to replicate original timber, the sash is attached vertically and the frame is joined horizontally. This increases its strength and rigidity, making the window more robust.

The Heritage Rose

A 44mm midrail is available in our Heritage range, creating a slim and elegant profile. It has internal glass lines that are subtly sculpted and external glass lines that are flat putty style, which match the astragal bars. Triple sealed brushpiles and silver or white gaskets will benefit you and give you many possibilities. You can fully customise it and use additional security measures to increase your security.

This is the second set of windows we’ve had fitted by Fenster. They are brilliant at every stage and I would highly recommend them. The staff are friendly and professional, they got the job done quickly and well, we’re very pleased with both sets of windows they fitted and would definitely use them again.

I contacted Fenster last week to see if they could help me. My French doors were failing to lock meaning we couldn’t leave the house. They sent Ben out the next morning who replaced the mechanism and also adjusted the door, closing up an annoying gap that’s been there for years. I wouldn’t hesitate to recommend Fenster to friends and family, a really helpful and efficient company.

We couldn't be more delighted with the professional service we received from Fenster Glazing. Nick turned up on time for the initial visit/quote which was fair and reasonable. After accepting the quote a survey was was carried out. The installers arrived on time and were polite and friendly. They covered everything up and left everything clean and tidy. After installation Perry called to check we were happy with the service. The quality of the french doors and windows installed were outstanding. We have no problem recommending this company. We would rate Service, installation and aftercare as 5 star.
I live in Milton Keynes, I contacted Fenster Glazing for an uPVC replacement door. From the beginning to the end, they conducted professional communication, from sales to the technicians coming to replace the door everything was perfect. I had a draught issue with my door and it is resolved now. I want to mention that I am also happy with the quality of the material of the door. I am hoping to have the same quality of service in the future if anything comes up—special thanks to Perry for dealing with everything. Ben

Highly recommended. I wanted a very specific style of doors to fit into our 1930s front porch. Fenster designed them, advised on colour & finish and they have produced exactly what I was looking for. The fitters were very polite and made sure everything was to my standards, and no mess left.
