Sash Horn Windows in Norwich, Norfolk and Suffolk

Q: What is a sash horn window?

A sash horn is a small decorative piece added to the top corners of the window frame. It copies the look of the joints found on real old wooden sash windows. This gives a uPVC window the classic look of a much older wooden frame, without actually being made of wood.

Quality and Performance

The horn detailing is combined with the sash, with a continuous gasket seal for weatherproofing. The multi-chambered profile helps reduce heat loss, and the shootbolt locking system includes a 10-year mechanical guarantee, so period character doesn’t come at the expense of modern security or efficiency. It lets you keep the authentic look of a period property without affecting everyday comfort.

The team was professional, friendly, and incredibly knowledgeable throughout the whole process. The windows look amazing and have completely transformed the appearance of our home.

You can really tell they take pride in their work. I would highly recommend this company to anyone looking for quality windows and reliable service.

 Trustindex verifies that the original source of the review is Google. So it’s been a few months since Windows Plus were here but I wanted to see if having 2 new doors and a couple of windows would actually make any difference to the river of condensation I’ve been coping with the previous two winters in my bungalow! Oh My goodness, Yes it certainly did!! This is the first winter I’ve been condensation free and it’s been absolutely fantastic, even feeling a bit warmer! David and Wayne were so professional and great craftsmen. The finishes were great and they dealt with any little niggles along the way with ease, even fixing my door bell (which by the way is still working great guys lol)! I couldn’t be happier with the price and service provided! I would definitely recommend Windows Plus! Many Thanks!

 Trustindex verifies that the original source of the review is Google. I have used Windows Plus a few times and have had nothing but excellent service every time. Adrian prices competitively with no pressure sales. The service Lee provided when fitting the door was second to none. Nothing was too much trouble and when left you would never know he had been. Great job thanks guys.

 Trustindex verifies that the original source of the review is Google. 5 stars I had been told I needed to replace my window by multiple companies and quoted over £1k for replacement. Spoke to Windows Plus and they sent out an engineer and repaired the window within a week. Super happy with the service and the finish - thank you so much!

 Trustindex verifies that the original source of the review is Google. A Glowing review from a warm happy customer. Windows Plus fitted a new door and front windows in my flat for a reasonable price. They have already fitted a new back door and windows. Excellent service from them and I'm very happy.

Frequently Asked Questions

What is a sash horn window?

Are sash horn windows suitable for listed buildings?

They are a popular choice where a period appearance matters, though requirements for listed buildings and conservation areas vary by property. We recommend checking with your local authority, and we are happy to advise based on our experience in the area.

If your property is listed or sits within a conservation area, we can talk you through what’s typically required before you commit to anything, based on the properties we’ve worked on locally. It’s always worth checking with the council directly too, but having that local experience means we can usually point you in the right direction from the start.

Do sash horn windows work the same way as standard sash windows?

Yes, the horn is a visual detail rather than a change to how the window opens. You still get the same sliding or tilting function, just with the added period character of the horn.

Sash orns are traditionally found on timber sash windows, and we replicate the look using uPVC or aluminium to give you that authentic heritage appearance without the maintenance timber requires. It’s a small detail, but one that makes a real difference on period and conservation properties where keeping the original character matters.

Are sash horn windows secure?

Yes, they feature a shootbolt locking system with its own 10-year mechanical guarantee, alongside accreditation to recognised national security standards. Locking points run along the full length of the sash, drawing the frame tightly into the seal for a stronger, more secure fit than a standard single point locking system. This gives homeowners complete peace of mind, without affecting the window’s traditional look.

Will you need access inside my home?

We know work in your home can be disruptive, so we plan each job carefully to keep things running smoothly. We use dust sheets and protective coverings throughout, and we clear away any debris or waste at the end of each day. If you have particular rooms or times you’d prefer us to avoid, just let us know in advance, and we’ll work around it wherever we can.
