Insulation for laminate - we master laying on a concrete screed or joists

How to insulate the laminate using a typical substrate?

In some cases, there is no need to lay any additional insulating material.And is used simply substrate .But it is important to choose it correctly.Sometimes substrate izolona, ​​polystyrene, cork and some other .The most environmentally friendly is, of course, cork.Durability is considered polystyrene.Next, you need to take care of a smooth surface.Minor defects will be equalized, but large cracks have repaired at the expense of the substrate.

thickness of the substrate itself can be 2, 3, 5, 10 mm.Select it depending on the desired effect on alignment and thermal insulation.Plus, it performs a sound-absorbing function.If this tube, then it must be laid on the polyethylene to prevent excessive moisture.And only then installed laminate flooring.

Insulation under the laminate onto the concrete screed or joists

In that case, if the base is made of concrete or wooden log, then put a heater for under laminate floor on a specific technology.Implemented flooring in several variants.

• on a concrete base. If it has any curvature, then use the self-leveling compound, for example, Ceresit. Then lay the film and put insulation for laminate.This can be a foam or polystyrene foam thickness of 20 mm are fixed between them by a tenon and groove system.On top of this insulation substrate lay.And then put the laminate flooring itself.
• on wooden joists .Board mounted with a distance from each other no more than 50 centimeters.The height of each board is defined by the width of the insulating material.For example, it can be placed concrete block, foam plates or of granulated mineral wool roll, sawdust, cellulose insulation, and many others.Top fixed plywood or OSB.Then only plank substrate (maybe cork) and the laminate itself.Fits all this with the help of screws.

floor heating under laminate

happens and another option - laminate heated .At the same time as a heating system can serve as a foil or an infrared heater.This method is not always recommended to use, since rapid heating cables there is a sharp temperature drop, and this in turn has a bad effect on the entire laminate coating and leads to its deterioration.

Therefore, it is practiced, but under certain rules, including the gradual and cautious heating cable.No matter which you choose a laminate floor heating (infrared or foil), their installation will still be engaged in the manufacturer, so the question of how to insulate the floor under the laminate should not occur.

As has been said, it is more important to observe some recommendations.Firstly, it is necessary to provide temperature control system.That it will prevent sudden changes in temperature and humidity.Secondly, before mounting the laminate should include a system for 1-2 days (so it just worked).Each day is added approximately 5 ° C and until all the coating will have a temperature of about 15 ° C.

Well, in general, the further installation of the coating is important to comply with the necessary conditions.Humidity - about 50-65%, room temperature - 18-22 ° C.
