Did you know that properly insulating a home can reduce heating and cooling costs by up to 20%?
With R-values ranging from R-3.3 per inch for fibreglass batts to R-6.5 per inch for closed-cell spray foam, the selection of insulation materials is essential for optimising thermal performance. Evaluating the thermal efficiency and eco-friendliness of options like mineral wool, recycled cellulose, and polyethylene foam can guide homeowners towards sustainable choices. Precise installation techniques and gap sealing guarantee maximum efficacy.
But how do these materials compare in real-world applications?
Selecting the best insulation materials hinges on evaluating thermal resistance (R-values), environmental impact, and specific application needs.
Stone wool, known for its R-value of 3.0 to 3.3 per inch, offers excellent fire resistance and acoustic insulation. Glass wool shares similar thermal properties with an R-value of 2.2 to 2.7 per inch, making it a versatile choice. Sheeps wool, eco-friendly and boasting an R-value of 3.5 to 3.8 per inch, appeals to sustainability-focused projects.
Cellulose, derived from recycled paper, provides an R-value of around 3.2 to 3.8 per inch. Hemp insulation, with an R-value of 3.5 per inch, is another sustainable option.
Selecting the right material guarantees efficient thermal performance and aligns with environmental and application-specific goals.
Evaluating thermal efficiency requires a thorough analysis of R-values, material properties, and installation techniques to guarantee peak energy performance. R-values measure thermal resistance; higher values indicate better insulation. For instance, stone wool offers an R-value of about 3.7 per inch, while cellulose provides around 3.5 per inch.
Material properties like density, thermal conductivity, and fire resistance must be considered. Installation techniques impact performance; improper installation can reduce efficiency by up to 30%. Sealing gaps and avoiding thermal bridges are critical. Ensuring insulation materials are properly cut and fitted enhances thermal efficiency.
The design focus should include continuous insulation layers and minimising air infiltration to maintain peak indoor temperatures and energy savings.
For homeowners prioritising sustainability, eco-friendly insulation choices like sheep’s wool and cellulose not only offer commendable R-values but also greatly reduce environmental impact.
Sheep’s wool, with an R-value of approximately 3.5 per inch, naturally regulates humidity and resists mould. It’s biodegradable and recyclable, making it an excellent green choice.
Cellulose, derived from recycled paper, provides an R-value of around 3.7 per inch. It’s treated with non-toxic borate, enhancing fire resistance.
Both materials fit well into design-centric projects focusing on sustainability without compromising thermal performance.
These eco-friendly insulations align with BREEAM certification standards, ensuring that homes not only perform efficiently but also adhere to rigorous environmental criteria. Such choices reflect a commitment to both energy efficiency and ecological responsibility.
Properly insulating different areas of a home, such as walls, roofs, floors, and ceilings, maximises energy efficiency and enhances comfort.
In walls, using batt or roll insulation with an R-value of R-13 to R-23 effectively reduces heat loss.
Roofs benefit from blown-in cellulose or mineral wool, achieving an R-value of R-30 to R-60 in attics.
Floors require rigid board insulation, such as extruded polystyrene (XPS), with R-values ranging from R-5 to R-10 to minimise thermal bridging.
Ceilings, particularly in multi-story homes, should use fibreglass batts or spray foam, meeting R-30 to R-38 standards.
Each area’s specific insulation needs promote optimal thermal performance and long-term durability, adhering to precise design requirements.
Choosing cost-effective insulation options requires balancing affordability with high thermal performance to guarantee energy-efficient home design.
Mineral wool, with an R-value of 3.7 to 4.2 per inch, offers robust thermal insulation at a moderate cost.
Flexible insulation rolls are versatile for walls and attics.
Recycled cellulose, providing an R-value of approximately 3.5 per inch, is a budget-friendly and eco-conscious choice.
Polyethylene foam excels at moisture resistance, making it ideal for floors and crawl spaces.
Prioritising materials that offer a high R-value relative to their cost ensures effective thermal insulation without financial strain.

star reviewExceptional service and beautiful flooring. Absolutely delighted with every aspect. Went above and beyond great customer service to meet our needs and timescales.
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 !!
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
Great company, always on the end of the phone to talk through design, measurements, fitting. The Oak is very high standard, looks amazing.
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.
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.
Found this company by accident whilst passing through Harrogate, but well worth a visit.Great products choice with helpful friendly service. The wooden flooring and beams look great in situ and we are very pleased with the transformed room. Would recommend and use again.
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.
From the moment we visited the Oak Design showroom, we knew that we were dealing with a top quality local company. Richard the owner, showed us around his design works with real pride of his product and service offering. Jamie as sales executive has discussed and agreed the options & design with costs to us and we have now implemented the first phase of our home improvement, with more work to follow. We are highly delighted with the finished product and would strongly recommend Oak Design to other interested clients. I also suggest that you pay them a personal visit at the Home Building & Renovation exhibition in Harrogate, as well as their wonderful showroom of Oak Solutions in Tockwith to get a personal guided tour.
I first used Oak by Design in 2021 for a oak porch, I used them again 2023 for an oak pergola. Both times my clients have been Delighted with the finished product. Both times the product was delivered when stated, everything i needed was on the delivery. Oak by design listened to what I required for both jobs. The quality of the oak is excellent, all joints fit correctly & if I had a problem I only had to ring and speak to them. R Brown Carpentry always recommends Oak by Design when asked about oak structures.
This is the second time that we have used Oak By Design for oak products and once again we weren’t disappointed. We recently ordered some internal oak doors and from the very start they were a pleasure to deal with. Joanne especially was extremely helpful and friendly, nothing was too much trouble. We were kept updated about the progress of our order. Unfortunately we needed to delay acceptance of the doors for a few weeks and Oak By Design happily agreed to store them in their workshop until we were ready for them. The quality of the doors is very high, they are very well made and finished, far better than any oak doors that you will buy “ off the shelf. “ They are all installed now and look fantastic. I would highly recommend Oak By Design and we will certainly use them again in the future if we require any more oak products. A huge thank you to Joanne and the whole team for a great service and a great product.
We were looking to have a bespoke oak and glass atrium for the front of our new house renovation. We wanted to find a company we trusted, who clearly understood our brief and could manufacture and install a high quality product at a competitive price. A big ask, but OakByDesign ticked all our boxes. Jamie and the team from the initial discovery meeting to completion of the installation were fantastic. The design, material quality and installation were first class and I would highly recommend you to include them within your project plans. Thank you all. Ben and Lindsay.
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.
Working with Oak By Design on our project was a pleasure and we were delighted with the results. Joanne was extremely helpful, quick to answer any questions and generally a great person to deal with! The quality and finish of the products - RSJ covers and Oak Windows & Doors were superb and look great. Would highly recommend working with Oak By Design and would not hesitate to use their services again for future projects!
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.
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.
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.
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.
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.
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.
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.
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.
I could not recommend Oak By Design more highly. Joanne and the team worked tirelessly to resolve an issue that was the result of my mistake when I ordered the porch. Great customer service.
Amazing craftsmanship from this company. The customer service from Joanne was superb. My questions and indecisiveness were never an issue and she was always on hand to offer advice and find the answers to my questions. Our oak porch has transformed the house and we are over thd moon with it. Would highly recommend Oak By Design. Joanne is an asset to the sales and promotion of this company and is very knowledgeable. Would give 10 stars if I could!
We purchased some engineered oak flooring and oak covers from Oak By Design and couldn't be happier with the finish and quality. They are spot on. Joanne was extremely helpful throughout the whole process and provided plenty of advice when necessary. Thank you
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.
Great personal service to ensure we got what we needed specific to our personal requirements. Quality is outstanding and there was a helping hand there all the way. The porch we ended up with was not cheap but having looked at others the quality of the Oak by design product shines through. Very pleased with the result and the complements from both neighbours and our builders keep coming.
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
A fabulous service and supportive through the design and delivery process. Highly recommended
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
Very impressed with Oak By Design. Customer service is fantastic and they were very patient in helping me ensure what I needed was the right size. Photos sent of oak cover before it was sent to me and end product was great. It was also not the most expensive either. Would definitely recommend.
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
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.
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
Posting on behalf of my Mother in Law, Shirley Abbott "Having planned to shop around, Oak By Design was my first stop. I had no need to look any further. Joanne patiently and professionally guiding me through the confusion of choosing the right flooring. The service and support from the staff was exceptional, efficient and helpful. And - my floor looks amazing!"
Superb! Fantastic! I can’t recommend enough. If you want gorgeous oak use this company. Oak by design made a porch for us and we couldn’t be more happier with it! It’s beautiful! The quality is first rate. Throughout the build Jo kept us informed as to the process of having the oak cut to size and installed. Jo and the team even sent us a lovely oak chopping board! Jack and his team who built it are fabulous! They go the extra mile. We have decided to use oak by design for a kitchen extension project in the future. Thank you oak by design for giving me a gorgeous porch! Charlie x
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.
Four 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.
We worked with Jamie from Oak By Design on a super project near Wetherby. There was plenty of oak in this design for the team to really show their worth - and they did. The attention to detail was excellent. If anything was not quite how the client wanted it, they were straight back to attend to this. The customer care was superb. We look forward to working with Oak By Design on another project soon.
Great company. Awesome flooring, we are very, very happy with the outcome. And great price which is always a bonus. Staff knowledgable & efficient.
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.
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.
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.
