What is the thermal conductivity of plasterboard?
Our Gyproc ThermaLine laminates comprise of Gyproc WallBoard (thermal conductivity 0.19 W/mK) and rigid foam insulation (thermal conductivity ranges from 0.02 to 0.04 W/mK depending on type).
What is the thermal conductivity of drywall?
| Thermal Conductivity – k – W/(m K) | |
|---|---|
| Material/Substance | Temperature |
| Gypsum board | 0.17 |
| Hairfelt | 0.05 |
| Hardboard high density | 0.15 |
Is gypsum board moisture resistant?
Gyproc® Moisture Resistant consists of an aerated gypsum core with water repellent additives encased in, and firmly bonded to, strong moisture resistant paperliners that are green in color. Gyproc® MR is a plasterboard that is suitable for drylining internal surfaces.
What are the properties of plasterboard?
Plasterboards are composed of a plaster core encased in, and firmly bonded to, paper liners to form flat rectangular boards (CEN 2004a). The properties of these materials, particularly the gypsum, can be modified to meet specific requirements, such as fire resistance, humidity resistance, impact resistance, etc.
What is Gyproc plasterboard made of?
Standard board product. Gyproc WallBoard consists of an aerated gypsum core encased in, and firmly bonded to, strong paper liners. Gyproc WallBoard is a plasterboard that is suitable for drylining internal surfaces.
How heavy is a 12.5 mm plasterboard?
To calculate the density of the plasterboard, establish the weight per square metre and divide it by its thickness (metres), e.g. 12.5mm Gyproc WallBoard weighs 8kg/m2, divide by 0.0125m = 640kg/m3.
What is the thermal conductivity of water?
0.598 W/m·K
Introduction. According to literature1 the thermal conductivity of water is 0.598 W/m·K at 20 °C.
What is considered low thermal conductivity?
As well, insulating materials such as aerogel and insulation used in homes has a low thermal conductivity, indicating that they do not let heat pass through them easily. Thus a low thermal conductivity indicates a good insulating material….Values for Common Materials.
| Material | Conductivity at 25oC |
|---|---|
| Vacuum | 0 |
| Water | 0.58 |
Is gypsum wet?
Traditional gypsum board products do not like water. Some of the new panels and boards are designed to function better in a moist or wet environment; however, the regular wallboard that is the most familiar to applicators must be kept dry.
Can gypsum get wet?
While drywall is made of some pretty sturdy stuff, it can sustain damage when exposed to water for too long. If moisture damage isn’t addressed swiftly, the structural integrity of the drywall becomes compromised, causing it to become soft, weak and susceptible to mold growth.
Is plasterboard a good heat insulator?
Regular plasterboard is commonly used for building work throughout the home, but only plasterboard specifically meant for thermal wall insulation will most effectively stop heat leaving through each wall in your home. Standard plasterboard does offer some level of wall insulation – it’s low price to purchase, too.
What is the compressive strength of plasterboard?
Petrone, Magliulo and Manfredi has investigated compressive properties of various commercial gypsum plasterboard and obtained a compressive strength rage of 3.02 MPa to 8.13 MPa [25] . Adhikary et. … The specific compressive strength range for the commercial gypsum plasterboards is 4.19-8.84 MPa/(g/cm 3 ) [25] .
What is the thermal conductivity of Gyproc wallboard?
Our Gyproc ThermaLine laminates comprise of plasterboard (thermal conductivity 0.19 W/mK) and rigid foam insulation (thermal conductivity of the foam ranges from 0.02 to 0.04 W/mK depending on type). What is the density of Gyproc plasterboards?
What is the thermal conductivity of gypsum foam?
Our Gyproc ThermaLine laminates comprise of plasterboard (thermal conductivity 0.19 W/mK) and rigid foam insulation (thermal conductivity of the foam ranges from 0.02 to 0.04 W/mK depending on type).
How to calculate the density of Gyproc wallboard?
To calculate the density of the plasterboard, establish the weight per square metre and divide it by its thickness (metres), e.g. 12.5mm Gyproc WallBoard weighs 8kg/m2, divide by 0.0125m = 640kg/m3. What is the fire resistance performance of Gyproc plasterboard?
Is it OK to use gypsum PIR on plasterboard?
Gyproc ThermaLine pir is one of the products within our plasterboard range that is certified to BES 6001 achieving a rating of ‘Excellent’. Gyproc ThermaLine pir is unsuitable for use in areas subject to continuously damp or humid conditions, i.e. above 70% RH, and must not be used to isolate dampness.
