The fire behaviour of naked EPS insulation material is not very relevant. The material is generally covered by other material which determines the fire behaviour. The insulation material is only affected by fire after the covering material fails and by this time the building or the compartment cannot be saved from total loss. Nevertheless, many negative misconception exist about the role of insulation material in the case of fire, the fire behaviour of EPS,the production of smoke and its toxicity. Facts show quite a different picture!

Mineral renders - dry powdered, cement-based with added lime and 'dry' polymers to modify the natural properties of the mortar. Unlike traditional renders, it is very thin and can not function properly without organic additives, which are responsible for its working properties and hydrophobicity.

Installation of external window sills is an extremely important stage in the process of insulating a building.

Learn how to properly prepare for it: what exactly you should pay attention to during the assembly work. Here are some great tips you should read before mounting exterior window sills.

Particular attention should be paid to application of mineral wool boards - why? Because the contact of the adhesive with the surface of the boards, as a fibrous material (often hydrophobized), has to be strengthened by tipping a thin layer of adhesive into the place where the base layer of the mortar will be applied.

The starter track (or base track / plinth track) is a first step in the process of mounting the insulation. This function is provided by specially profiled aluminium or plastic tracks. They are often universal regardless of the insulation thickness, but you can see the variety of sizes on our website.

It turns out that the method of bonding is extremely important and may affect the durability of plates or have an impact on safety during a fire. Check why insulation boards should be mount with the method of apply 3 equally spaced adhesive mortar dabs through the centre line of the insulation board and a strip around the edge.

Reinforced layer - an adhesive layer (mesh coat layer), in which at least one layer of fibreglass mesh (reinforcing mesh) is embeded in. 

Reinforced layer is a crucial element when mounting thermal insulation. It is responsible for receiving and transmitting thermal pressure, protecting against the damage and providing a stable base for thin coat textured renders and paints.

External wall insulation application should start with the preparation and verification of the substrate to which we attach EPS or wool. Regardless of whether we are dealing with the substrate in a new building or an existing building (sometimes with the original layer of insulation, which is to be modernised), we need to ensure that the surface is stable, dry, even and clean. A properly prepared substrate should have sufficient strength, enabling the mounting of insulation.
