When it comes to overhead garage door replacement, there are many important decisions which you have to make. One of them is to decide on the level of insulation which you want for your garage. Find out what level of insulation you require and how to make the best choice.
The different garage doors available from brands like Clopay and Martin have different levels of insulation depending on their design. The level of insulation is measured by the R-value. This is the ability of an object or material to block the warm air inside a closed space. The higher the R-value is, the better the insulating capabilities of a door are.
It is natural to ask yourself why insulation matters so much. Its main job is to prevent heat from escaping from the house. In this way, you will enjoy higher energy efficiency and lower energy bills. When the garage is better insulated, the vehicles parked inside and the objects stored inside have better protection from the elements. This can save you quite a lot of money that you would otherwise spend on car and garage door opener repairs.
There are three main garage door design options for you to pick from. The most basic models are the single-layer ones. They consist of a single sheet of steel. This sheet metal structure has a fairly low R-value. The two-layer models have a layer of insulation material added to the steel sheet. This material is typically polyurethane or polystyrene. The three-layer models have the highest R-value due to their structure which consists of insulating layer surrounded by two sheets of galvanized steel. It is worth pointing out that the glass garage doors traditionally have very low R-value and in many cases it is not measured at all.
Overall, it is always best to invest in a door with the highest possible R-value for maximum protection and energy efficiency.
