    Osmo UV Protection Oil Extra 2.5l

    One of the most regular questions that we get asked is how to care for your new summerhouse - in particular what to treat it with.

    In many ways, this can be a matter of personal opinion: Some people prefer to let the cedar fade down to its natural silvery-grey colour. A new building will begin this mellowing process as soon as it is assembled and will be noticeable after just a few weeks and will be quite silver after a year. If you like this mellow look then you can re-apply the same treatment that we use in the factory - a clear Barrattine wood protector formula every couple of years. This helps to prolong the life of the wood and reduces staining but does not alter the mellowing process. This treatment is easy to just use when needed

    If you would really prefer to try and keep the original cedar colour in the wood then we can recommend using this Osmo oil product on new Summerhouses and Greenhouses as it prolongs the colour of new cedar by protecting it from Uv light. It is quite a viscous product so needs to be applied with a brush and will need 2-3 coats for best results.

    This high-quality product is in effect a sun block for your wooden building. A 2.5l tin will be enough to coat a 6’x8’ summerhouse building approximately four times. Due to the effectiveness of this product, your building may only need treating every couple of years. Only the exterior of your building will require treating.

    IMPORTANT: In the case of a summerhouse; we recommend using this product a couple of weeks after construction. This will ensure that the cedar has had time to air-dry but has not yet started to fade. In the case of a greenhouse, it is better to coat the individual parts whilst the greenhouse is flat packed before assembly. Bear in mind that you will need multiple coats and there is a long drying time.

    Osmo uv-protection-oil extra is a satin, Clear finish for exterior. It is based on natural oils, is microporous, and does not crack, flake, peel or blister. Osmo uv-protection-oil extra prolongs the renovation time significantly. As a stand alone finish, with two coats, It prolongs the greying process on vertical surfaces by up-protection factor 12 compared to untreated wood. The finish contains active ingredients which protect it from mould, algae and fungal attack. Easy to renew, no sanding or primer necessary. Easy to apply, will not dry during application.

N.b. This greenhouse comes with Cedar bar cover capping as Standard. Aluminium cover capping in the moss colour is an optional upgrade. Gutters, base, and other aluminium components come in moss powder coated aluminium  as standard.

The clever design of these new Alton Evolution models has created a cedar greenhouse that is ideal for modern needs, and by using innovative and strong jointing technology, the Evolution models are delivered flat packed in a self-assembly format. This removes a large amount of cost from the double handling and storage of large unwieldy glazed panels used on other models, and put simply this allows us to put more wood into the greenhouse. 

The result is an extremely strong, high quality cedar greenhouse, designed to be maintenance free- even with the standard cedar bar capping. If you upgrade to the moss coloured aluminium bar capping system you will combine all the benefits of cedar and all the advantages of Aluminium in one hybrid greenhouse. 

The best type of wood - and more of it!

The frame is made from Canadian Western Red Cedar, which is extremely high in natural preservative oils which, even without further artificial treatment, make it virtually immune from decay. Cedar also has a unique subtle aroma which can deter pests. The frame is based on mostly planed 2x2 (44x44mm) and 3x2 (69x44mm)

We factory treat your Alton Evolution greenhouse in a clear treatment - thus not masking the natural colour variation of the cedar wood. In time, your greenhouse will mellow into a silvery colour which is so distinctive to cedar. The Moss colour of the metal components is designed to blend in perfectly with this mature silvery colour.

- A metal base keeps the wood well away from the damp area on the floor

- Louvres and Automatic roof vents are standard.

-  High Eaves - often overlooked by greenhouse buyers, but it is important to consider. High eaves means the greenhouse feels a lot bigger, and it is far more comfortable for you to work in.

- The guttering and downpipes are included as standard.

- Glass overlaps at eaves, protecting a vulnerable area of your greenhouse from rot.
