    Garden Offices Energy Saving Insulation
    Energy saving insulation
    The walls, floor and roof of our garden offices are all insulated to lower energy costs. We use foil backed Polyurethane to insulate our garden offices, which is proven to retain heat better than cheaper alternatives such as polystyrene or rockwool. The U values of our insulation are as follows: 0.64 W/m2 K in the roof, 0.62 W/m2 K in walls, and 0.70 W/m2 K in the floor.*Insulation means a reduction in loss of heat from an area that has been heated to a different temperature. If no heat has been applied, the insulation will be nominally the same as the outside temperature.

    Garden Offices EPDM Roofing
    Garden Offices EPDM Roofing II
    EPDM Roofing
    Our Garden Offices feature an EPDM covered roof. EPDM has been widely used in commercial and residential flat roof applications for over 30 years and has an enviable record for durability and waterproofing. We’re so confident in our choice of roof material that we give a 10 year guarantee against rain water penetrating it. Being made from one large sheet it also means that the roof won’t be covered in clout nails as is the case with felt roofing, but please be aware that there may be some bubbles trapped under the EPDM material when it is laid and/or creases. The pictures above show a typical EPDM roof installation on one of our offices

Average Seller Rating:

Good afternoon. You recently delivered a Lienne III garden office. I have to say that the negative reviews online are all complete bollocks - the delivery guys were great, a window unit that smashed on delivery was replaced inside of a week without me even getting in touch, and the quality of the building is as good as I expected. THANK YOU. However, there was one piece missing - the guttering and guttering clips. Would you be able to have these delivered at some point? Thanks a lot, Mike Potts

Hi Mike. Thank you for your review. Our customer service has been warned and will be able to look into it. Our apologies. We hope you enjoy your new Garden Office.

we purchased this after having a good look around and found the ability to go to a show room and see the building ourselves helped in the final decision If you are interested in one of these I advise you to visit and see for yourself. I opted for the plastic feet rather than my own concrete base and I'm glad I did a lot less hassle as they can level it up themselves also had an excellent team of fitter that did a great job and tidied up every day very happy with end result and with a small oil filled radiator nice and warm on cold days the kids love it with a wifi extender plugged in they are happy to play for hours the only thing extra we added was more plug sockets as it only comes with 2 as standard we added another 6 to make 2 on each wall as its a big space.
