Forma Heritage Windows

Heritage look composite & all timber frames

Supplied and fitted across Norfolk and Suffolk

Designed to complement British heritage architecture, Rationel Forma and Forma Plus windows will give you timeless details, such as bevelled edges and angled glazing beads, which make these windows the ideal fit for traditional-style heritage homes or older properties. Optional glazing bars add the perfect finishing touch.

We are Norfolk’s distributor for Rationel, founded in Denmark in 1954 and the leading manufacturer of composite windows and doors in Europe. The Forma Window range is Rationel’s heritage-style window and is suitable for heritage property renovations and those looking for a heritage aesthetic for their new-build property. 

For a more modern, minimalist style see their Aura or Velfac range.

Suitable for new builds & renovations

Forma or Forma Plus?

What is the difference between Rationel Forma and Forma Plus? The Forma window frame is made of solid wood, with no external cladding. The Forma Plus window frame is composite, but not as we know it! Unlike traditional composite often used for doors (typically wood and uPVC), this composite has a solid wood core and an external aluminium cladding. The Forma window has an expected lifespan of 60 years and the Forma Plus has an expected lifespan of 83 years.

A great window for heritage and heritage-style homes.

Forma and Forma Plus heritage-style windows feature a sleek, flat frame with clean lines and a flush finish, adding a touch of Scandi-style to every room.

The chop samples here show an in-depth look into the inner workings of the windows and also give an idea of the visual difference between the Aura and the Aura Plus.

 Because the whole frame is aluminium-clad, the Aura Plus achieves a cleaner more minimalist finish with fewer visible joins.

Forma Window Frame Colours

Forma window frames come in a wide selection of colours. The options displayed here are the standard colour range available for both Forma and Forma Plus. More colour options are available – We will show you a swatch at the quote stage as screen colours will vary.

It is also worth noting that should you wish to change the colour of your Forma windows in the future this is possible for both Forma and Forma  Plus. 

Forma windows are made of timber and can be painted directly, and Forma Plus windows have an aluminium-clad exterior which can be changed without altering the timber core.

@habify_uk were great and everyone was lovely.We had3 windows and 2 doors clad and plastered. We went with SIPs so theycould be installed and ftted quickly as we have a busy house and we wantminimal downtime.Sales process.Rob was friendly and professional.There was one annoying small niggle none ofthe samples had names onthem. Rob was transparent and said they had just updated the colour so theyhadn't been sorted out yet.There was no Cladding sample and purely because of my impatience,I wentand picked them up myself.Agreed a price was told 3-day process. max 4 daysThe 3-day'is because they were SIPs, they are pre-cut to size so the installationcould be quick.To add complexityl asked for a tunnel catflap. Which was notanissue.OficeSarah was professional every timeI calledin and here is my`1st issue.WhenIam choosing a premium service,lshould not have had to do anything.Whenam the one who has to ring for information, days and times. Includeasking for a receipt for my deposit. Is not really acceptable. When the receiptwas done, and then there was 9 working days without hearing anything andyou had to email to find out what was happening.12 working days later was told there was a delay.Then waited another 8 working days, to get a ft day. This was only afterlcalled sales and asked what was happening.(Paying a large deposit and the communication being a bit sketchy start tomake you question your choice to the pointI rechecked the company)Hugo the MD came to me with a fit date and work started.The FitThe fitter Sam and Brad were brilliant uber professional a credit to thecompany.Day1 explained the process and just cracked on.SIPs and this was the biggestissue.They should of been pre cut (this was nothing to do with @habify_uk but thesupplier) This slowed every down as the lads had to re-measure and cut thefull size panels to shape.Thelads carried on but they hadto come away a couple on times. At no pointwas my home unsecure the lads made sure. There communication was great.On one of the time they had to come away they told me one thing, and theoffice pulled them to another job and did notinformed me, so there was someannoyance.The whole job spanned over 3 weeks which is someway over the 4 days max.The fitter were really good and even whenl asked ifthey could move thecatlap over they went over and beyond.Really happy with the plasterers work butI did not see him as he was in andout whileIwas at work.After the fitHugo himself wantedto come and see the job and us due to the issues.Professional and understanding of my issues and took responsibility.ConclusionIam really happy with the product/fnish and these litle things are justdisappointing.Itseems looking through the reviewsI am the one off.AndIwould recommend them to the point ofIwill use them again for my otherproject.

The whole experience with Habify was a great one. Hugo came to estimate the works and was very efficient and helpful. Sam and Brad came to fit my new conservatory roof, veranda and decking and were professional with great attention to detail, nothing was too much trouble. I would definitely recommend this company the new roof has made the conservatory useable all year round

Great communication and very responsive ( same day in most cases). Quality product and on site team worked so hard every day they were here, offering pragmatic solutions to a couple of irritating problems that cropped up along the way.

We wanted windows that were in keeping with the style and period feel of our property but with the convenience of UPVC. The windows we ordered have the aesthetics of timber windows but with the convenience/durability of UPVC.Fair pricing and a great service from initial discussion to fitting.

We had our old conservatory replaced back in August with Habify, we are over the moon with the finished result! We were well informed throughout the process and the fitters/plasterers/electricians were all so lovely and even worked through the heatwave we had. The customer service has been excellent and even if we had an issue they were quick to respond and fix. Would highly recommend Habify.

We decided to go with a local company, Habify, for our window replacement. We had bifold doors fitted at the back of our home.We couldn’t be more pleased with the end result. From start to finish it was good experience with Habify. All the people we dealt with were friendly and knowledgeable.We gladly recommend this company.
