Insulating a shed may seem like a pretty abstract idea. You may be asking yourself, "Why would anyone want or need to insulate their shed?"
First of all, lets briefly describe what spray foam insulation is. Spray foam insulation is two liquids, which when combined at the tip of a spray gun, form a spray which doubles in size once it hits some sort of material (a wall, floor or ceiling). This foam gets into every nook and gap offering superb insulating, moisture infiltration and draft proofing qualities.
Spray foam insulation is by far the best material for insulating sheds it is the prefered insulation material for any metal structure in the US and in the the EU.
Sheds, be they of wooden construction or metal, can be extremely cold and damp during the winter months, or swelteringly hot and humid in the summer.
Condensation can build up on the ceilings and drip down onto the contents of the shed.
This would be a concern if delicate materials such as photos, clothes, curtains or paperwork are stored there. The damp would not only fade and stain the items, but it would also encourage the growth of mold and mildews effectively ruining the items. The damp articles will also attract insect which could wreak havoc on your valuables.
Another concern is that the moist damp air will quickly rust any metal tools, saws, bicycle parts and chains. The damp in an un-insulated shed can also cause wooden furniture to warp, buckle and split.
Closed cell spray foam is applied directly to the walls, ceiling or underfloor. It forms an airtight, insulating barrier from the external environment.
It completely halts the ingress of damp and the formation of condensation. During the summer, it will keep the interior of the shed at a pretty stable ambient temperature.
