In addition to energy-saving measures such as altering building orientations, reducing the window-to-wall ratio, and increasing the number of window layers, selecting energy-efficient new insulation materials in walls, roofs, and floors is an extremely effective approach. Let me tell you that extruded polystyrene (hereinafter referred to as EPS) is one of the best materials for exterior wall, roof, and floor insulation in recent years.

Expanded Polystyrene (EPS) External Wall Insulation Technology Advantages. Essentially eliminates the impact of thermal bridges, offering excellent energy-saving effects. By enveloping the entire building with EPS boards, which have an extremely low thermal conductivity, it stabilizes the indoor cold and hot environment. This not only prevents condensation at thermal bridge locations but also eliminates heat loss caused by thermal bridges.

Install extruded foam boards:

(1) Standard panel dimensions are 1200 mm x 600 mm, extruded boards are cut with a tool knife.

(2) Bonding methods include strip bonding and dot bonding.

3) Strip Application: Evenly spread the prepared adhesive mortar on the back of the extruded board and scrape it into strips with a notched trowel.

Dot adhesive method: Apply a 50mm wide layer of adhesive mastic around each extruded polystyrene board. Gradually increase the thickness from the edges towards the center, with the thickest part reaching 10mm. Then, on the extruded polystyrene board, spread 3 circular adhesive mastic dots with a diameter of 100mm and a thickness of 10mm, and 6 dots with a diameter of 80mm, for exterior wall thermal insulation boards, also with a thickness of 10mm.

Mixing adhesive mortar:

Pour one part of clean water into a clean plastic bucket, add 5 parts (by weight) of dry mixed mortar, and stir continuously while adding the mortar. Then, use a handheld electric mixer to blend for 5 minutes until well mixed, the insulation board is what, and the consistency is moderate.

(2) Allow the configured adhesive to sit for 5 minutes, then mix for 2 minutes before use. The mixed adhesive mortar should be used within 1 hour.

(3) The bonding mortar is simply prepared by adding clean water; no other additives (agents) are permitted.
