Enjoy your Log Cabin come rain or shine with our Severn Insulated Log Cabins. These have all the fantastic features of our existing Log Cabin range but with our unique Warmalog, a pre-manufactured 62mm sandwich of timber and polyisocyanurate insulation unlike inferior materials such as rockwool or bubble wrap. The Warmalog design helps keep your Log Cabin warm in the winter and cool in the summer, so you can extend your living space all year round. Whether you intend to use our Log Cabin as a place to unwind with family and friends, or as a Garden Office, you can rest safe that your stuff will be safe inside with our industry leading 4 point locking system. The insulated cabin comes to you untreated, except for the pressure treated bearers, so you can treat or paint it to your own preference, style and budget. Unlike some competitors our thick pressure treated bearers, which come with a 10 year guarantee, are included in the price.

Make sure you make the best possible use out of your Log Cabin, whatever the season. Dunster House’s combination of insulation in the wall logs, floor and roofing allow you to keep the temperature in the cabin just right and use it whenever you wish.
You will need to prepare a solid base that is square and level to allow you to build this insulated log cabin successfully on your property. You can use concrete or our RapidGrid Foundation system. We recommend a base of 5.0m x 3.2m for the Severn Warmalog®. The only extras needed are a superior quality light coloured 'Barn' paint to seal the outside of the insulated log cabin, as well as a clear silicone sealer for the joints after decorating. These are available from your local decorator supplies.
Our thermally-insulated Warmalog® cabins are built of special logs - consisting of triple Tongue and Groove logs with a 62mm timber and polyisocyanurate ‘sandwich’, that has better thermal insulation characteristics than competing brands, but at a very reasonable price. Just another new and exciting product, thanks to Dunster House!
As well as the walls of the Warmalog® Cabin, the 50mm floor and 60mm roof provide considerable insulation. The windows are Double-Glazed, with two panes of 4mm toughened glass and a 16mm air gap in a 24mm sealed window unit. These and more thermal design factors give Warmalog® cabins a U value of 0.69. This excellent heat retention makes the Warmalog® the kind of building that will keep you cool in those warmer months while staying warm in the coolest part of the year.
The Warmalog® quality timber building is well-suited to a number of uses, such as an office, work-out room or even your own private bar. So, if you need the extra room for working out or to work or any other reason, it’s reassuring to know that the changing seasons won’t affect your lifestyle. You can keep on doing what you need to do regardless of the weather! Strong and secure, the Warmalog® has an Espagnolette locking system on its wide-opening French Doors. The roof is held up and strengthened by large Purlin beams, and below your feet, pressure treated floor bearers keep the damp away from the body of the cabin.
The Warmalog® is easy for home owners to assemble. Log Cabins will never be the same again!

Delivery Service
All of our products are delivered using our own fleet of vehicles, not sub-contractors. We have a large number of vehicles dedicated to delivering our quality products so we can guarantee maximum care is taken during the delivery process.
Our deliveries take place Monday to Friday between the hours of 8:00am and 7:00pm.
When the delivery vehicle is unloaded, it is important that you check to make sure all of the items and instructions have arrived and are correct. You will also receive a component list to check your items against. If anything is missing or damaged, it is essential that you note this on your paper work when you hand it back to the delivery driver.
Prices for our delivery services can be found on individual products.
Please note that goods will be delivered to the first point of contact at the front of your property e.g. on your driveway. This must be within 20m from the delivery vehicle (Safely Parked at Kerbside). Our team will be responsible for assessing the risk of carrying out an assisted delivery upon arrival at the property. If they feel that there is no clear access as stated above, they will have to leave the items at the kerbside.

Important Notice for All Customers Regarding Measures During COVID-19 Outbreak
During the period of uncertainty surrounding the coronavirus pandemic, Dunster House is continuing to follow the official guidance from the UK Government and Public Health England in order to ensure the safety and security of our customers and our staff.
We are continuing to operate at full capacity in terms of our Dispatch and Delivery Service, however we will be implementing some temporary measures in order to minimise the need for contact between our staff and our customers, particularly those customers who may be self-isolating or in quarantine.
Please see responses to any questions that may be asked below:
Q: Will my goods be delivered during the COVID-19 period?
A: Yes. We will be delivering all orders whilst also limiting the contact between customers and delivery staff.
Q: How will you make sure that social contact is adhered to during deliveries?
A: We are taking serious measures to maintain the Health and Safety of both our customers and staff members and will therefore ensure that our delivery drivers maintain a respectful and appropriate distance during delivery.
Q: What happens if I (the customer) am self-isolating?
A: If you are self-isolating and wish to avoid all contact with our delivery drivers, then please inform our Dispatch Team when you receive a call to arrange your delivery. The driver will then place the delivery paperwork through the letter box for you to check against the product. You can then leave the signed paperwork copy on the delivered goods and return to your property whilst the driver remains in the vehicle.
Q: What are the terms and conditions of the delivery?
A: The rest of the terms of delivery remain unchanged. Namely, the drivers will unload your goods from the kerbside and deliver to the front elevation of your property only, such as a driveway. In most cases, parts will be unloaded separately meaning that the delivery can take some time.
Q: Where can I find more information?
A: If you have any questions regarding your delivery, you can telephone our Dispatch Team. Contact details for the Dispatch Team of your nearest branch can be found on your order confirmation. If you need to track your delivery or access your manuals in advance of your delivery, you can visit the Customer Log In Area of our website https://dunsterhouse.co.uk/customer-login-area/log-in
Thank you for taking the time to read about our terms and advice during this period. We hope you can enjoy your Dunster House garden product for many years to come.
