Do you feel cold seeping through walls in harsh winters, or watch your air conditioning bills soar in scorching summers? A high-performance thermal insulation mortar holds the solution, and its core strength comes from professional building additives produced by Longou. Founded in Shanghai in 2007, Longou has been deeply engaged in the building additives industry for over a decade, serving many countries worldwide. With quality products such as Redispersible Polymer Powder (RDP), Hydroxypropyl Methylcellulose (HPMC), Hydroxyethyl Methylcellulose (HEMC), and cellulose fibers, it injects stable performance into thermal insulation mortar, making indoor temperatures more comfortable and energy efficiency higher.
What is Thermal Insulation Mortar?
Thermal insulation mortar is an ideal building material for winter heating and summer heat insulation. Composed of cement, lightweight thermal insulation aggregates, and special additives, it combines excellent thermal insulation properties with energy-saving and environmental protection advantages. It is widely used in thermal insulation of new building walls, energy-saving renovation of old buildings, and various special areas requiring additional thermal insulation. It should be noted that thermal insulation mortar needs to be used in conjunction with other wall insulation systems, especially for uneven walls or walls made of special materials (such as aerated concrete blocks). In these cases, thermal insulation mortar helps level the wall and form a protective insulation layer.
The "Performance Code" of Thermal Insulation Mortar: Longou's Core Additives
The performance of high-quality thermal insulation mortar relies on precisely proportioned additives. Longou's product range is designed to optimize thermal insulation mortar:
- Redispersible Polymer Powder (RDP): Longou RDP models such as VE3311 and VE3211 can form a tough elastic network, effectively buffering the stress caused by temperature changes and keeping the insulation layer intact through seasonal alternations;
- Hydroxypropyl Methylcellulose (HPMC) & Hydroxyethyl Methylcellulose (HEMC): Longou products like HPMC LK20M and LK40M boast excellent water retention, slowing down the mortar's drying speed, preventing cracks caused by uneven moisture evaporation, and making the insulation structure more stable and durable;
3. Cellulose Fibers: Cellulose fibers slow down moisture loss in the mortar, especially at high temperatures, helping balance moisture evaporation between the surface and inner layers, making shrinkage more uniform and thus preventing crack formation. Even when applied thickly in high-temperature environments, the mortar layer remains intact, building a "crack-resistant barrier" for the insulation structure.
