High performance, tough, dependable and exclusively designed for your walls, floors and roofs, Kingspan Styrozone is a market-tested and user-trusted range of polystyrene insulation. This XPS (Rigid Polystyrene insulation) is very rare to find due to its special nature. It can be used anywhere as it is flexible in thickness ranging from 30mm to 140 mm. Kingspan insulation has evolved with the making of this brilliant material. It is tough when it comes to insulation and very mild when it comes to nature as the blowing agent used to manufacture it has ODP (Ozone Depletion Potential) at absolute 0. Its non-fibrous material makes it very safe and extremely easy to install. It is isotropic in nature. Its material is sturdy and withstands dilute acids and also alkalis. The goal of having a passive house can only be achieved if we make efforts and fit the required infrastructure beforehand. Insulation refers to the techniques of protecting something by introducing a special material to stop the loss of heat or sound, and it is a must if you are planning to build a perfect house. Here are some places in your building which desperately require Styrozone Insulation:

Styrozone Basements

Basements are areas of our home which require special insulation. They are easily attacked by moisture and this can result in dampness of walls which can also lead to diseases. Styrozone basements are specially designed to resist this ground moisture. A recent study showed that air-borne moisture in building there is a risk of surface condensation which may cause breathing problems.
You can either go for H350 R model which has a thickness of about 100mm, thermal conductivity from 0.029-0.031 W/m.K and can serve well till 75 degree Celsius. It has a very high comprehensive strength of 300kPa. It is easy to install.It will require board of size 1.25 by 0.6m. This is not affected by air infiltration. Or you can choose N300Rwith thermal conductivity of about 0.035-0.040W/m.K .It is specially made with blowing agents with a very low GWP (Global Warming Potential). It will make sure that moisture stays far away from your basement with its highly resistant strength.

StyrozoneFloors and Walls

Different buildings have different floor and wall requirements. Some may require a heavy-duty flooring while others may require cold-store flooring. Floor insulation is therefore very important. On the other hand, we need to make sure we do not lose any sort of energy from our walls which bring to the concept of wall insulation. There is a special Thermawall with model number TW53. Based on these needs there are four varieties of styrozone floors and walls you can choose from: H350R, N300R, N500R, and N700R.It will also require a board of size 1.25 by 0.6m

Styrozone Inverted Roofs

Similar to flooring, different buildings design different roofs. Some of us like to keep it flat while some intend to keep it vegetated. Both these kinds can be perfectly insulated using either H350R or N300R models. It will require board of size 1.25 by 0.6m. Since H350R has a high compressive strength, it is common to all types of house insulations.


The H350R board is easy to cut and easier to install. You firstly need to install a solid waterproofing system on the roof as roofs are in direct contact with moisture. The first thing you need to do is cover the boards nicely with a non-woven polyethylene. This needs to be sealed properly under the flashing.

Now, we see how to install a single layer of insulation. The trick is simple, either install the board diagonally or install them with longer edges (length) positioned at right angle (90 degrees) to each other. And if you plan to install two or more layers, the process will be the same but you just need to check that the joint of the board do not coincide with other layers.

You ballast layer should be at least 50mm deep with a diameter of about 20-40mm and its installation should be done as fast as possible if you wish to go for paving slab ballast. You must have adequate knowledge about all types of insulation methods so as to decide wisely which method will suit you and your building the best.


Before finalising the thickness of the board you can make calculations there is a ‘U-value calculator’ with which you can finalize according to your satisfaction. There is no compulsory measurements you have to use for you house insulation. The number of layers, thickness of each layers, all depends on how much insulation you wish to have in your building.
