Scientifically Tested GUTEX Thermoroom Interior Insulation System GUTEX Thermoroom possesses all the qualities necessary for optimum interior insulation: Introduction Interior insulation is a consideration particularly for buildings for which exterior insulation is not possible or ill advised due to the historical significance or listing of the building. ✓ Insulation against the cold in winter Thanks to its minimum thermal conductivity (λ=0.038 W/mK), it creates warmer wall and ceiling surfaces for improved indoor comfort. The advantages offered by interior insulation include the absence of scaffolding,...

To ensure the building is not damaged by the retrofitting of outer walls with interior insulation, the existing situation and status of the building must be evaluated prior to beginning with the planning. Key factors are diffusion permeability, capillary action and the insulation performance of the wall elements (U-value). Suitable action to prevent the outer wall from becoming damp due to driving rain and rising damp must be taken prior to beginning with refurbishment work. Diffusion permeability GUTEX Thermorooms' diffusion capacity makes it an ideal insulation for interior use. It absorbs...

NEW: GUTEX Flankendämmkeil An example The following simulated thermal images show building sections both with and without the corner insulation wedges. By adhering to several important principles, mould and mildew, which occur with the presence of high humidity or low temperatures, can be easily avoided. Corner junctions of exterior walls with ceilings and interior walls In Germany, the DIN 4108-2 standard for the insulation of buildings specifies interior surface temperatures of greater than 12.6° C to avoid condensation and thereby prevent mould and mildew. To maintain 12.6° C across all the...

Planning the Insulation of Corner Junctions When is it necessary to insulate corner Detail Innendämmung Anschluss AW-IW junctions? Situation 2: Junction between masonry interior walls and masonry exterior walls, with timber stud The following tables will help you determine if it is necessary to insulate corner junctions. Based on the building substance of the structures and their respective thermal conductivity properties, the approximate U-values of walls can be determined using the tables below. Use the U-values for the exterior and interior walls in the tables at the bottom of the page to...

Details about the concrete ceiling used in the table below: • Thermal conductivity (λ-value) of concrete is 2.5 W/mK • Reinforced with 2 % steel; 16 cm thick • 10-mm edge insulation strips, thermal conductivity (λ) is 0.040 W/mK • 15-mm floor insulation; thermal conductivity (λ) is 0.040 W/mK Original exterior wall: 24-cm masonry...

Installing the Insulation Boards 4.  Installing the boards Install the GUTEX Thermoroom so the full area of its rear side adheres to the suitably prepared substrate. Make sure the joints and boards are vertically and horizontally plumb. The offset of the boards must be min. 20 cm. Use of additional mechanical fasteners is unnecessary when using GUTEX Thermoroom. Guidelines for installing the insulation boards 1. Proper preparation of the substrate Check the existing substrate for soundness, removing loose wall covering and repairing crumbling plaster, etc. Apply a primer to sandy surfaces to...

Existing exterior wall with any U-value, sd-value of maximum 30 m, high to extremely high capillary action in the outer 2 - 4 cm of the walls’ interior. Existing exterior wall with any U-value, sd-value of maximum 30 m, low to moderate capillary action in the outer 2 - 4 cm of the wall’s interior. Option 1: Mineral plaster Base coat Base coat Apply GUTEX Klebe- und Spachtelputz mortar to the newly clad walls to create a coat of at least 4 mm. Embed the reinforcement mesh in the outer third of the coat. Apply GUTEX Klebe- und Spachtelputz mortar to create a coat of at least 4 mm. Embed the reinforcement...

Installing over Wood Structures When installing the wood fibreboards over wood structural elements, the element’s substrates must be at least 12-mm thick and consist of composite wood sheathing or solid wood. Suitable common wood screws or staples, the latter with a back width of 10 mm, may be used. The offset of the boards must be min. 20 cm. The penetration depth of the fixings must 50-100at least 12 mm. be mm The following figures provide information about the quantity of 50-100 mm fasteners required. GUTEX Thermoroom 40 – 100 mm 6 screws with 60-mm ∅ plastic discs per fibreboard Fixing methods...
