On at least one in four sites we find that since the garages were built 50-70 years ago, resurfacing of the common access area has been carried out, one or more times causing the garage floor level to become lower that the access area. Naturally water flows into the garage.
When we refurbish garages our work is in regard to the replacing of the old components, not in building up the floor level. Another trade is involved which we can organise but it may be cheaper to obtain quotes locally.
Anti-condensation sheeting is a cost effective way to overcome the problem of condensation forming on a single skin steel sheet. A self-adhesive fleece is applied to the underside of the steel during the profiling process and this allows the sheet to absorb up to 1kg of water per square metre, stopping any water dripping. The fleece can be applied to a variety of profiles both traditional corrugated and box profile.
Why condensation forms:
Condensation forms on un-insulated metal sheets when the temperature and humidity conditions reach the dew point, moisture condenses on the underside of the sheet. If there is a lot of condensation, drops of water form and start to fall. The traditional method for dealing with condensation is to try to insulate the roof so that the sheets temperature never reaches the dew point. An insulated roof is more expensive and that a single skin roof and is not always the most suitable choice.
How product works:
Anti-condensation sheets stops dripping by absorbing water and retaining it within the fleece. When temperatures rise the water that has been absorbed by the fleece will start to evaporate back into the air and the fleece will dry out. It is vitally important to ventilate the building when using this type of sheeting for this reason.
As mentioned above the fleece can only hold so much moisture and if a wet vehicle with a hot engine is parked in a garage during cold weather the temperature of the air in the garage increases and can absorb more water which will be all over and under the vehicle. As the temperature falls during the night the moisture will be deposited on the coldest surfaces which can be so intense that droplets form and fall resembling a leaking roof which is not, in fact, leaking.
