Self adhesive insulation board is a type of insulation material with built-in bonding function. By coating adhesive on the back of the insulation board, it can be easily attached to various surfaces without the need for additional glue or other fixing measures.
application field
In the field of architecture, it can be used for thermal insulation of walls, roofs, floors and other parts, as well as for insulation of air conditioning systems, chilled water pipes, air ducts and other pipelines.
Electronics industry: Due to its excellent insulation and sealing properties, it is often used as a sealing and shock-absorbing material for internal components of electronic products, such as mobile phones, tablets, etc.
Automotive industry: Seals used in automobile manufacturing, such as door seals, window seals, etc., can effectively prevent the penetration of water, gas, and noise, improve the sealing performance and ride comfort of vehicles.
When selecting self-adhesive insulation boards, multiple factors such as usage scenarios, performance requirements, and quality standards should be considered comprehensively to avoid affecting the insulation effect and safety due to product unsuitability or quality issues. The following are detailed purchasing precautions:
1、 Clearly define usage scenarios and requirements
The performance of self-adhesive insulation board needs to be matched with the application scenario, avoiding a "one size fits all" selection:
Application location:
Building exterior wall/roof: it is necessary to focus on the compressive strength, aging resistance, fire rating (for example, Class A incombustible materials are more suitable for high-rise exterior walls), and consider the bonding durability with the base course (for example, whether to withstand wind and rain, temperature changes).
Pipeline/equipment insulation (such as air conditioning pipes, water heaters): Priority should be given to selecting flexible, waterproof and moisture-proof types (such as rubber self-adhesive boards), which should fit the curvature of the pipeline and cover the temperature range of the medium (such as high-temperature pipelines that need to withstand above 100 ℃ and low-temperature pipelines that need to withstand below -30 ℃).
Indoor decoration (such as walls and ceilings): Pay attention to environmental protection (formaldehyde emissions), flatness, and some scenes need to take into account sound insulation effects (such as better sound insulation with closed foam structure panels).
Environmental conditions:
In humid environments such as bathrooms and basements, it is necessary to choose boards with high waterproof rating (such as IPX7) and anti mold properties; High temperature environments (such as kitchens and equipment rooms) require confirmation of the upper temperature resistance limit of the board (to avoid thermal deformation); In cold regions, emphasis should be placed on thermal conductivity (≤ 0.03W/(m · K) is preferred) to ensure insulation efficiency.
2、 Core performance parameter verification
Thermal conductivity: The lower the value, the better the insulation effect. For building insulation boards, it is recommended to choose products with a power consumption of ≤ 0.04W/(m · K), while pipeline insulation can require a power consumption of ≤ 0.035W/(m · K).
Adhesive strength: The viscosity of self-adhesive is crucial, and the parameters (such as ≥ 0.3MPa) need to be checked. Attention should also be paid to the weather resistance of the adhesive layer, which should not flow at high temperatures or become brittle at low temperatures (please inquire with the manufacturer about the applicable temperature range of the adhesive layer).
Density and compressive strength:
Density affects the durability of the board. For example, it is recommended to use rubber insulation boards with a density of ≥ 40kg/m ³ to avoid structural looseness caused by being too light;
The compressive strength (such as ≥ 100kPa) ensures that the board does not deform after stacking or trampling, especially suitable for laying on the ground or roof.
Fire rating: According to GB 8624 classification, it is recommended to choose Class A (non combustible) or Class B1 (flame retardant) for building exterior walls, and Class B2 for indoor non load bearing parts, but it is necessary to avoid open flame environments. Attention: Some products claim to be "fireproof" and require a fire detection report.
Thickness and specifications: Calculated based on insulation requirements (e.g. recommended 50-100mm for northern walls and 30-50mm for southern walls), while considering construction convenience (e.g. standard specifications of 1m width and 2m length are easier to cut).
3、 Material and process identification
Substrate quality:
Rubber sheet: observe whether it is a closed bubble structure (no obvious depression when pinched and pressed, quick rebound), without bubbles or holes;
Rock wool composite board: Check whether the rock wool layer is uniform, without slag or clumping, and whether the polyurethane layer is tightly bonded to the rock wool (without delamination during peeling);
Aluminum foil composite board: The aluminum foil should be flat, undamaged, and firmly adhered to the substrate (not falling off when rubbed by hand). The higher the reflectivity, the better (≥ 85%).
Self adhesive layer: The high-quality adhesive layer should be evenly covered without any leakage or wrinkling, and there should be no residue on the adhesive surface when peeling off the release paper; A simple test can be done: stick it on a smooth wall surface (such as tiles), pull it after 24 hours. If the board falls off instead of the adhesive layer peeling off, it indicates insufficient adhesion.
Environmental friendliness: When using indoors, attention should be paid to the release of formaldehyde and VOC, and it is required to comply with GB 18583-2008 "Limits of Hazardous Substances in Adhesives for Interior Decoration Materials". Priority should be given to products with "Ten Ring Certification" or third-party environmental testing reports.
4、 Qualification and Brand Selection
Certification and Reporting:
Essential: Product certificate of conformity, factory inspection report (including key parameters such as thermal conductivity and fire rating);
Bonus points: ISO9001 quality system certification, fire protection product certification (for high fire rating products), environmental protection certification, etc.
Brand and reputation: Priority should be given to brands that are deeply involved in the field of insulation materials, such as Ales and Kemenfules for rubber and plastic products, and Sisil and Longpai for rock wool products. These brands have more mature production processes and complete after-sales support, such as providing construction guidance and warranty commitments. Avoid choosing "three no products" without branding or labeling, as these products often suffer from issues such as adhesive failure and poor insulation performance.
5、 Practical details and cost-effectiveness
Weather resistance test: Inquire with the manufacturer if they have aging resistance test data (such as a decrease in bonding strength of ≤ 20% after 500 hours of ultraviolet irradiation), especially for outdoor use, which should be given special attention.
Cutting and construction adaptability: Self adhesive insulation boards need to be attached to the base layer. If the base layer is uneven, a slightly elastic material (such as rubber) can be selected; At the same time, confirm whether the board is easy to cut (without breakage or slag), which facilitates the handling of corners and irregular parts.
Cost effectiveness comparison: Don't just look at the unit price, it needs to be calculated comprehensively based on thickness, density, and service life (such as high-quality boards with a service life of more than 10 years, inferior boards that need to be replaced after 3-5 years, and higher long-term costs).
6、 Avoiding pitfalls tips
Be wary of "false labeling parameters": If the thermal conductivity coefficient is claimed to be 0.02W/(m · K) but there is no testing report, or the fire rating does not match the actual one, the merchant can be required to provide a report from a third-party testing agency (attention should be paid to the timeliness and pertinence of the report).
Pay attention to the shelf life of the adhesive layer: Self adhesive has a certain storage period (usually 12-24 months), avoid purchasing expired products, otherwise there may be a decrease in viscosity.
Do not blindly pursue "multifunctionality": if you simultaneously claim "ultra-high insulation+super strong fire resistance+ultimate low price", you need to verify carefully to avoid performance fraud.
Based on the above points, self-adhesive insulation boards that are suitable for various scenarios and have reliable performance can be selected to ensure long-lasting insulation effect and safety without hidden dangers. It is recommended to request samples for testing key properties such as adhesion and flexibility before purchasing in bulk.
