Stay Warm in Winter, Cool in Summer: Insulating Your Summerhouse for Maximum Comfort

How To Insulate a Summerhouse Floor, Walls and Roof

  • 1/ Measure the size of your summer building. Check the height of the walls, measure the roof area, and take the dimensions of the floor if you want to insulate it
  • 2/ There are several methods of insulating the building – i.e. fibreglass type, insulating it with polystyrene, or foam insulation sheets – so decide which one will be best for you.
  • 3/ Contact your local builder’s merchants or maybe B&Q and order the required insulation
  • 4/ To insulate the garden building walls you will need to cut the insulation to size. And this will fit in between the walls, and you then need to tack it into place.
  • 5/ Using plywood, hardboard or T&G timber boards, you would then need to cover the walls.
  • 6/ It’s similar when insulating the summer building’s roof – i.e. cut the selected insulation to size for the roof, polystyrene is my recommendation, as this can be cut slightly oversize so it can be wedged into place
  • 7/ Line the roof with hardboard or plywood. Screwing these roof sheets into place is recommended so they can be removed if need be.
  • 8/ The final thing to do with the roof is to cover the joints in the roof and wall panels with covering fascia strips. This ensures you are insulating of your summerhouse or hut has a tidy cosmetic finish
  • 9/ How to insulate the summerhouse floor – You will need to fit insulation in between the floor joist and tack it into place before assembling it.
  • 10 Alternately, buy a summerhouse designed with insulation already fitted in place. This will be a bit more costly but the easiest option. See our full range of insulated summer buildings on this page.

Insulated Summer House UK. How To Make The Right Choice.

The outdoor summer house for your garden is traditionally enjoyed through the warmer months, possibly being used as a storage place through the winter. How about being able to use it all year round? By investing a little more and having your luxury summer house insulated, you can use this wonderful building all year round. Your children can be out from under your feet and can use it as their own, with their computer games, music or chilling with their friends. Mum or Dad could use it as a ‘man cave’ or ‘she den’ for their hobbies or pastimes. An insulated summerhouse could be used as a home office for your business, and if so, the cost would be tax-deductible. A win-win situation for you!

Can I Insulate My Summer Building After Delivery?

It’s reasonably easy to insulate a summerhouse in the UK if you have semi-reasonable DIY skills. You need to buy polystyrene or fibreglass insulation and then cut this and fit it in between the internal framework. The fibreglass insulation will need tacking into place to stop it from moving before you fix the inner skin. This can be plywood, hardboard (which you can get with an attractive veneer on it) or even T&G boarding. This is OK for the walls, but the roof can be a little tricky. You need to get the insulation in place, often with gravity working against you. This makes fitting the inner skin fiddly. You would need 2 or 3 people to do the roof. After you have completed that, it would also be a good idea to use cover strips over the joins to finish it off.

What Other Options Do I Have?

We can supply insulation on all of our Platinum summer houses for sale to suit your requirements. The walls and roofs can be lined and insulated, enabling you to benefit from all-year-round use. We normally use Kingspan insulation which is a solid composition with foil backing. There is a range of different internal linings. Before finishing the building, it will have internal trims fitted to ensure a smooth finish. With a choice of internal cladding, you can choose one to suit you.

How Much Will Insulation Cost For My Summer House

All of our Platinum pages have links to the prices of the basic buildings. On the order form, you will see the cost for that particular model.On some; there is even an option to insulate the floor for even better protection from the elements. One of the most common questions is whether you can afford it. Well, if you would like to use your new garden building all year round, then it’s worth working out what this extra use is worth to you. To have full use of your office or hobby room is a great asset and a little piece of calm away from our mad world.

Will My Summerhouse Be Warm In The Winter?

If your building is insulated, then it will be nearly as warm as inside your house. Just like any building, during the colder spells, you will have to have some form of heating. The ideal solution is an electric heater. You can’t use a gas heater like Calor gas. Apart from the apparent flammability risk, it creates a lot of moisture which will tend to warp the timbers and cause dampness. Besides keeping your new wooden summerhouse warm in the winter, insulation will help to keep it cooler in the summer. This is something which not many people think about. I never used to think about it, but on our show site, we had a typical summer building next to a designed insulated one, and I was checking them over.

When I went from the normal one into the insulated one, I could not believe the temperature difference! I had to go back into the un-insulated one to check, so it’s well worth doing.
