The espagnolette offers an oak door and frame both security and long-term stability. There are many types on the market, but not all espagnolette systems or multipoint locking systems are the same.
From the close-up image, you will see 'hooks' that appear on the top and bottom contact points. On a UPVC door, this added engagement will keep the door secure.
However, on an oak door, this natural product will slightly move to acclimatise against the ever-changing atmospheric conditions. This is a normal and it will settle over time,
As such, the 'hook' shown would be a hindrance, and therefore all oak doors have a 'straight' shoot bolt to ensure the door and frame align perfectly and allow for some tolerance.
When closing the door within its frame, the uplifting movement of the handle will engage 3 (sometimes 5) points of contact between the door and the frame.
They are a central point near the cylinder (the actual lock) and further points, one situated at the top and another at the bottom.
This engagement will align the door within the frame at three points. The door is NOT locked at this point.
To lock the door, operating a key within the cylinder will do this. Note, you cannot completely lock the door unless the handle has been lifted upwards to engage all points of contact.
1. 20mm throw twin deadbolts.
High security nickel plated alloy deadbolts fully penetrate the keep rail and help prevent forcing apart of the sash and frame.
2. Weather seal compression adjustment in the keeps.
Together with the enhanced tapered deadbolt design, the adjustment in the keeps provides for low operating forces. With ±2mm adjustment it is possible to adjust for misalignment of the door during and after installation.
3. Heavy duty steel keeps
Heavy duty keeps manufactured using high grade steel, plated to comply with Grade 5 corrosion resistance requirement of BS EN1670 European Standard.
4. Latch and centre deadbolt
Engineered alloy sprung latch and nickel plated steel deadbolt provides the ThunderBolt™ with maximum strength in the centre of the door.
5. High performance gearbox
Tested to 100,000 cycles the sprung gearbox offers the lowest possible operating forces and helps prevent handle ‘droop’.
6. Cylinders and handles
ThunderBolt™ has been designed to harmonise with Winkhaus XR6-51 Kitemark profile cylinders (KM531333) and ArmorShield™ cylinder guard and to meet PAS24 security and durability standards. The locking System is compatible with industry standard handles and also with the Winkhaus Palladio™ and DDA handle range.

Left us a
star reviewFour years ago we took the decision to completely gut an old farmhouse and start again with it, we started looking for a supplier of oak to refit all of the internal doors, door casings, skirting and flooring. Our carpenter recommended Oak By Design. He wasn't wrong! All of the oak has been completely top notch. As the old house has settled into it's new skin it has moved and cracked in various places, the only thing that has been stable and unwavering is the oak. The customer service has been superb, with them continuing to supply exactly the same items, with the same quality over the course of 4 years. They even indulged our designs for furniture for our "boot room", with Shoe pigeon holes and a bench which we could store wellies under (as pictured). The doors supplied by them are reassuringly heavy and sturdy, with a proper "thunk" as you close them, cutting off sound from the rest of the house. There may be other, cheaper suppliers of oak out there, but none with the same level of quality, longevity and customer service as Oak By Design. If you want to do it right (& once!) use these guys.
Fantastic staff with fantastic craftsmanship. Great communication and always on the ball. I would highly recommend oak by design, I don’t think you could get a better quality oak porch anywhere. Extremely pleased with ours , always getting compliments from fellow villagers
Oak by Design have made 2 oak framed rooms for us, sunroom at the front and and "moonroom" (photo) at the back which encompasses a shower room, work area and storage. They have been helpful at every stage and the outcome is simply brilliant. They make the whole house feel roomier and brighter and are beautiful places to be. GE North Yorkshire
I was sourcing an oak RSJ cover (circa 5m length) for my extension and found Oak by Design on the internet. All of the reviews I could were glowing and so I contacted them......And I'm so glad that I did. Joanne Fisher answered my initial call and she looked after my order from beginning to end - in terms of ensuring that I got exactly what I wanted she/they provided a superb service - everything on time - delivery in to the Peak District to suit when I wanted. The quality of the the RSJ cover is fantastic thick solid oak that matches my oak floor - looks amazing. If you want anything oak I can thoroughly recommend Oak By Design.
I firstly used oak by design a couple of years ago for an open oak porch. They were extremely helpful and everything was delivered on time to the highest quality. The porch went together with the oak dowels provided and looked great when it was all slated in. They have also supplied me with a oak beam for a fireplace natural random finish and it looks good.
We decided to get an oak porch to make our home more attractive and we are so glad we did as it really is beautiful ! Joanne and the Team have been professional, friendly and just a pleasure to deal with ! Thank you so much !!
Oak by Design were extremely helpful at all stages of my project from helping and advising me to choose the most appropriate beam through to advice on fixing the beam. They were extremely patient with changes to my beam dimension requirements finally providing a solution to suit my project. They provided photographs on completion of the beam prior to dispatch to ensure that my requirements had been met. I was extremely impressed by the quality and finish of the beam which has become the focal point for my fireplace project. Oak by Design provided customer care of the highest quality and I would highly recommend their services.
Firstly, the product quality was superb, a beautiful oak mantle piece for my fire place, gorgeous. The installation was quick, efficient and fitter very friendly. The price was very reasonable, actually very good value. But what makes it all SIX STAR, ( but we I can only give 5!), was the customer service. When walking in the shop I was perfectly attended to, I was given samples to take home and they remembered to call soma days later to see what I thought. Order to install time was very fast for such a bespoke service. My experience was world class, great to deal with a brilliant local/small business, I totally recommend.
Outstanding customer service from a company that truly cares. I’ve only dealt with a small amount of companies where buying experience totally outstrips the monetary value & this is one of them.
On behalf of Shears PHG Our customer was looking at having an oak porch built for their property in the West Midlands we got in contact with Joanne at Oak by Design and she was really helpful, always friendly on the phone and polite nothing was too much trouble. Joanne kept us up to date through every stage and our customer is really pleased with the results of the Porch it looks great and we wouldn’t hesitate to use them again in the future
Ordered an oak mantle beam from Oak by Design and they quickly called to check the finer details. Unfortunatly, the beam was slightly damaged on arrival by the courier company. Oak by Design immediately arranged to have it picked by DHL, transferred back to Yorkshire from Kent, repaired and sent back within 2 days, with no quibbles. The beam is beautiful, as is the high quality customer service by these people. Fully recommend using this company. Anthony Slater, Tonbridge. Tonbridge.
From the beginning the customer service has been superb, excellent help and advice when choosing the flooring, delivery arriving when promised and a product which is extremely high quality. We have replaced the majority of our flooring downstairs and we are so pleased with the result that we would have paid more. Fantastic.
We worked with the team who designed a wonderful porch for our house near Harrogate. It has been an amazing addition. Simple but effective - excellent craftsmanship using authentic materials. We are absolutely delighted with the transformation and everyone who sees the porch says how great it looks. Thanks to all the team at Oak By Design.
My company has ordered 2 porches with Joanne from oak by design, and have more planned in the future. They've been brilliant from start to finnish. Great communication right through. And the quality of the product is exceptional. Do not hesitate to order.
Great service by a friendly professional team, a pleasure to work with. The end result of our oak glazed leisure spa and outdoor kitchen looks fantastic. Great job
Thank you Jo for your assistance and detailed guide every step of the way with my new porch. Very pleased with the finished product, I would highly recommend Jack and his team for installation
We got a fantastic garden structure from Oak by Design. It is a very handsome building and the design process was very patient, to say the least. We didn’t really know what we wanted, so we had to be guided through it. And we are delighted.
Great service from start to finish, Joanne was great help. Designs were spot on and so happy with the porch. 10/10. Fully recommend.
Amazing customer service from beginning to end . My builder was in awe at the quality of the oak porch components. Call them and ask for Joanne - what she doesn’t know isn’t worth knowing! It’s not every day you invest in a “proper” porch so do it right. You’ll definitely be delighted!
Fantastic service and quality of product. I couldn’t be happier with my Oak porch, which was designed to my specification with the minimum of fuss. Joanne was so helpful and nothing was too much trouble. Incredibly well engineered and looks fantastic. Thank you so much.
From the start of our enquiry, the service provided was excellent. Joanne was a great help and the oak porch structure looks fantastic on our new build. It completely changed the look of the house. Very quick delivery could not recommend enough.
My client was looking for ways in which to make his conversion (of an early seventies house into a period family farmhouse) “stand out from the crowd”. whilst maintaining a commercial eye on his expenditure, as the house was being converted for resale profit. Making the choice to meet with Richard and explore possibilities for incorporating some Real solid Oak features into his plans proved to be the making of the project. By taking lots of advice from Richard on both the size and structure of the components we were able to incorporate three key features. The beautiful and bold roof trusses and purlins for the open plan kitchen are simply a joy to behold. The stunning full height gable window which is directly glazed into the large framework can be appreciated from both the the kerbside and of course from within the cosy snug on the ground floor or the amazing first floor main bedroom where we incorporated some additional exposed roof beams just purely for effect. All in all it is fair to say that these significant choices certainly created the wow factor my client was looking for. Having managed to pre sell the property well before completion it in itself demonstrates the benefits of keeping these sorts of real oak features as part of a modern build. I have no hesitation whatsoever is saying that if anyone is looking to get advice and is serious about investing in quality oak products they should have no need to look further than Oak by Design. Thanks again Richard for all your help , guidance and continued support which is a credit to you and the craftsmen you employ.
We are ‘over the moon’ with our beautiful oak porch made by Oakbydesign .From our initial enquiry to delivery and installation the service and attention to detail has been outstanding! A very big thank you to Joanne who was so helpful and friendly from start to finish which made the whole process such a pleasure. Highly recommend anyone looking for an oak porch to choose Oakbydesign . Yvonne Grant.
Really delighted with the new porch by Oak by Design. It adds a super feature to my converted barn. Thanks to Joanne and the team.
We were delighted with our new porch. Right from our initial contact with Joanne at ObD, through the design and the installation by Jack and his team the service has been excellent. We would have no hesitation in recommending ObD and Jack to anyone thinking of a high quality oak porch. Thank you to all involved.
Excellent quality workmanship and materials. Very easy and friendly to deal with on the phone. Everything done on time and no problems at all. Will definitely use again next time I need an oak porch or any other oak structures.
My wife and I recently purchased an oak porch from Oak By Design. We are delighted with the porch and it has been much admired. We did get some help assembling it but everything fitted together perfectly.
Exceptional service and beautiful flooring. Absolutely delighted with every aspect. Went above and beyond great customer service to meet our needs and timescales.
A great company to deal with. Professional from start to finish and always there to assist with any queries. Highly recommended.
I wish I could give more starts!! We looked at many companies before finally choosing Oak by Design. We are so glad we chose them. They were excellent from start to finish. They worked with us to find a workable design that was to our liking. Our door looks amazing (despite the building site that still surrounds it!). Their customer service is of the highest standard, Joanne could not do enough to help us. I would not hesitate to recommend them.
Found Oak by Design searching for a new front porch to replace a canopy and knew immediately that this was company for the job and I was not disappointed. I already knew what I wanted and Richard, very patiently, developed my basic requirements, with a number of iterations, into a full detailed design. As I live outside their site working area I decided go for supply only and to install the porch myself. It was delivered as promised and it looked great even on the pallet! It took me a while to fit but it was very satisfying and the result is fantastic. The quality of the aged oak and carpentry of the timbers is excellent. I’m delighted with the porch supplied by Oak by Design - it looks superb.
Oak by design were a fantastic company to deal with. They made us some treads for a bespoke stair case from large pieces of air dried oak. They were very thorough in making sure that they understood exactly what we wanted. They made excellent suggestions for small changes to our own design in order to produce a better finished product and to manage the cost. We were very happy with the treads when they were delivered. They look fantastic and fitted perfectly to the steel frame which was made by a third party. I could not recommend them more highly.
Fantastic service from start to finish, I would have no hesitation in recommending this company or using them again. Very professional and helpful. Joanne was great in assisting us with choosing both styles and colours of the beams and cladding.
We ordered two bespoke doors and two bespoke porches for our house build from Joanne at OByD. We were specifically delighted with Joanne's attention to detail (and patience! lol) making the overall customer experience excellent. The product was equally fantastic, the product quality was truly beyond our expectations. Joanne is super helpful and knowledgeable, and kept my spirits up throughout our project. We would 100% recommend OByD, and specifically Joanne, for all your standard and bespoke oak requirements. H&D
As the owner of a local joinery business, Robert Davis Joinery, I have had the pleasure of using Oak by Design on several occasions over the last 8 years. They have produced bespoke interior products for me including Oak doors and timber moldings. The staff in the office and the workshop are always very helpful and friendly and the standard of the workmanship and materials are always of a very high quality.
What can I say, Oak By Design have been the most fantastic company to deal with. Joanne was so helpful, friendly and professional. She really seemed to care about our project, which made such a difference. We had 4 oak RSJ covers made and 2 fireplace mantles. The finish is outstanding. Everyone believes they are solid beams, which was just what we wanted. The care and attention this company will give you is 2nd to none and I would highly recommend them. Pictures will follow when we complete our project, thanks again Oak By Design. x
Excellent customer service. Very friendly. Explained in detail. Product is beautiful. Would recommend. Company sent photos of finished product prior to dispatch to confirm our happiness with their work.
Oak by design provided our engineered oak flooring. From our initial meeting and supply of samples to the final delivery we have been provided with excellent service. Carl has been in touch throughout the process and provided updates about the lead time and expected delivery dates. We are delighted with the flooring. Very happy to recommend Oak by design.
First class service and product . Our car port and steps look fantastic and blends in with the existing buildings beautifully. Would definitely recommend them.
On behalf of John Docherty: Oak By Design were a great company to deal with; helpful, knowledgeable, professional. The quality of the oak supplied to us for our bespoke porch was first class. Nothing was too much trouble for this company, and we will definitely be using this wonderful company again in 2022.
Great company. Awesome flooring, we are very, very happy with the outcome. And great price which is always a bonus. Staff knowledgable & efficient.
From the initial quotation right through to the delivery and after service Joanne has been brilliant and given me an excellent product. I have just ordered another porch for another project from them and I will continue to do so for future projects . Thomas and Bell Building Contractors Ltd
We can thoroughly recommend Oak by Design. Not only did they provide the best of oak floors and oak staircase to suit our new, contemporary home, but they returned to make good a problem which was not their fault. Going the extra mile separates great companies from ordinary firms. Thank you Jamie & Billy. From Mike & Barbara, York.
Having lived with our porch for over 2 years I can honestly say it’s the best addition to our house we ever made. Not only does it look fantastic the quality is outstanding. I love that it keeps the mud out of the hall and provides a seating area to remove muddy boots.
