Give a Stylish Touch to Your Dream Home with Our Experts
When it comes to designing and building our homes, we are at the stage where we are faced with making decisions. Our first big mechanism is the overall cost which has a big impact on the designs of your homes.
One of our objectives is to create a design that is sustainable, and for an exterior wall, that usually connects to energy efficiency.
Our work is dedicated to the core values of reliability and quality of work. Foam pouring concrete is one of the excellent method to achieve this goal.
Why would we set our building on a layer of foam insulation?
With today’s designed oriented goals of sustainability and energy efficiency, the right usage of insulation is considered more important than ever.
As home demands with building codes having greater envelopes and continuous insulation, home builders and consumers are looking for building strategies that delivers the performance without paying a premium.
Building your house on foam can raise a few potential aids because of its durable and versatile feature:
- To limit the thermal bridging.
- To make a high performance building.
- Solid foundation & Moisture Management.
Thermal bridging in building can contribute to a multiple problems including significant amount of heat loss through the massive structure at the base of the building.
Building performance is improved by thermally isolating the building foundation from the ground, not only from an energy performance standpoint but also in terms of comfort and moisture management.
All about Rigid Foam Insulation and Its Applications
For foundation and under slab applications, up to one-quarter of a building’s energy loss is due to lack of insulation in below-grade areas, including the foundations and under slabs.
Now the envelopes of high-performance buildings are common above ground, the relative amount of total heat lost beneath grade will raise if these spaces are not addressed.
CONSEQUENCE: Superintendents will progressively meet with below grade and under slab insulations on all building types.
This blog will make you understand of how two common rigid-foam insulations perform in these settings.
It also discusses moisture absorption, thermal performance and installation procedures for below-grade and under slab insulation.
Two different types of rigid foam insulation, which you’ll catch in a minute.
All rigid foam insulations has a certain pros and cons. Fiberglass and cellulose insulations cannot break air movement, but rigid foam can.
Two common rigid foam insulations having different properties are listed for below-grade applications are expanded polystyrene (EPS) are extruded and polystyrene (XPS).
An easy way to recognize EPS is that it is commonly white. This insulations is composed of expanded polystyrene beads fused into sheet stock and blocks of various densities, compressive strengths and sizes.
EPS is least-expensive type of rigid foam used by professionals. Insulation industry advances with EPS developments.
EPS has gained wide-ranging acceptance in wall, beneath-grade and under-slab applications due to its low moisture absorption, strength and has established long-term performance.
EPS insulation blocks can be custom-cut into variety of shapes and sizes to fit the requirements of wide ranging job specifications.
Building professionals have used EPS successfully in below-grade applications for decades.
XPS rigid foam is usually blue or pink in color having smooth plastic exterior. Typically, XPS panel aren’t tackled with other material. This type of rigid foam won’t absorb water and is stronger and more durable than expanded polystyrene.
So it’s undoubtedly the most versatile form of rigid foam.
For creating XPS, manufacturers combines and melt polystyrene with blowing agents and additives, then force the liquid mixture by a extrusion die in a uninterrupted feed, where it is shaped, cooled and clipped to size.
Most commonly, this product is available as board stock of fixed size and thickness.
Manufacturers often tinge XPS a prime color for brand recognition.
EPS vs. XPS: which one is a better differentiator?
There is much confusion in the marketplace regarding weather EPS and XPS insulations resists moisture better.
The two types of manufacturing processes produce finished products with very different performance properties, although both types of insulations are comprised of polystyrene.
Manufacturers of both EPS and XPS frequently hype the fact that their products can be recycled, but a comprehensive Life Cycle Analysis shows that EPS has a better overall environmental influence when compared to XPS.
XPS is manufactured in a continuous extrusion process that produces a homogeneous closed cell crossed section, whereas EPS is manufactured by expanding spherical beads in a mold, using heat and pressure to fuse beads together.
What you need to do is –just look at the science to see the truth (because SCIENCE doesn’t lie)
- Science has proved that XPS foam is more moisture resistant than EPS foam
- Science has proved that XPS foam holds R-value better than EPS foam at lower mean temperature when water is present (The “R” stands for resistance to heat flow. A high R-value means greater resistance to heat flow and thus, greater insulating value).
How to Install Rigid Foam Insulation below Grade?
The insulation (weather EPS or XPS) is installed over the damp/waterproofing, after that layer has sufficiently cured on building foundations.
Troops can use mechanical fasteners or polystyrene-compatible adhesives to attach the insulations.
Putting a bead of polystyrene-compatible seal and pitch on the top of the insulation board minimizes water infiltration behind it.
The rigid form insulations typically should be installed with a poly vapor diffusion retarder between the gravel and insulation for under slab applications.
Moreover, insulation is applied beside the edges of the slab as it is a primary surface for heat loss. To avoid damage to the insulations, it is essential to ensure removal of any rough surface or irregularities in the substrate before installing the rigid foam panels.
Key factor: It is essential to confirm all details with the insulation manufacturers and local building department, and to guarantee appropriate construction techniques to drain water away from the building.
