How to make an extension from foam blocks to a house?

Adding on to your house can be a fun and fulfilling project. Foam blocks are among the most widely used materials for this kind of extension. These lightweight, manageable blocks are a terrific option for both professional and do-it-yourself builders because they have good insulating qualities and are relatively easy to work with.

We’ll walk you through all the necessary steps to construct an extension with foam blocks in this guide. We will cover every aspect of project management, from planning and preparation to finishing touches, to guarantee project success. Whether you’re building a garage, an additional room, or just more storage, following these pointers and methods will help you build something sturdy and long-lasting.

After going over the equipment and supplies you’ll need, we’ll go over specific instructions for building the walls, laying the foundation, and finishing the outside and inside. With the appropriate strategy and a little perseverance, you’ll soon have a lovely, useful addition that mixes in perfectly with your current house.

An extension from foam blocks to a house made of foam blocks – the advantages of the material

Cellularly structured building materials are preferred when choosing what to use to build an addition to a private home because they are lightweight and provide the required safety margin. It is frequently employed in the creation of foam concrete, which offers a host of significant benefits over other kinds of building materials.

Foamed concrete blocks offer both professional builders and individual developers the following benefits:

• Accelerated blocking pace of blocks. From block elements with enlarged dimensions, walls of the structure are rapidly erected;
• possibility of independent work. For the construction of foamed walls, special preparation is not required;
• Fire safety. Blocks made of foamed concrete belong to non -combustible materials and do not emit harmful substances when heated;
• Environmental purity. For the manufacture of foam blocks, environmentally friendly raw materials are used, harmless to the environment and human health;
• Minimum shrinkage. Foam block masonry retains its size, preventing the cracking of the finishing layer of plaster;
• reduced thermal conductivity. It is provided by the cellular structure of the material, which reduces heat loss;
• long service life. The durability of buildings erected from foam blocks exceeds five decades;
• ease of mechanical processing. It is easy to give the foam block the required shape using a standard wood saw;
• the required margin of safety. Foam concrete blocks are capable of withstanding significant loads, while maintaining the integrity of the array;
• vapor permeability. Air vapors freely escape from the room through the foam block array;
• affordable price. Using foam blocks for the construction of extension walls allows you to reduce the estimated cost of expenses;
• reduced weight of blocks. Due to the light weight of foam block walls, the load transferred by the foundation to the ground surface is reduced.

Block building materials are becoming more and more popular due to the improved performance characteristics of foam concrete products, which also enable construction work to be done on a variety of soil types, including problematic soils.

Disadvantages of a building made of foam blocks compared to other materials

Foam blocks have numerous benefits, but they also have a few drawbacks. When preparing to construct a foam block addition to a home, these should be considered.

The primary drawbacks of foam blocks are:

• increased hygroscopicity of foamed concrete, associated with the cellular structure of the material. The porous material loses its thermal insulation properties as a result of saturation with moisture. To protect foam blocks from over-moistening as a result of exposure to natural factors, reliable protection is required;
• unaesthetic appearance of block products, which have a grayish color and increased surface roughness. The attractiveness of the foam concrete walls of the extension is achieved by applying protective and decorative plaster on the facade and interior sides of the building.

The drawbacks of foam concrete blocks can be readily overcome with the use of contemporary plaster mixtures and finishing supplies.

Requirements for a building for the construction of a foam block extension

The following characteristics of the building to which an extension is intended must exist:

• stability;
• strength;
• durability.

When considering the expansion of a foam block house, several considerations need to be made:

• safety margin and age of the main building. Strength characteristics gradually decrease during operation. It is necessary to make sure that the age of the building and its stability allow for the extension;
• properties of the soil on the site of the proposed construction. It is necessary to carry out geodetic exploration and determine the depth of the aquifers and the nature of the soil;
• the need to obtain permission to carry out the redevelopment of a residential building. You should first think over the dimensions and design of the extension, develop a project and issue permits.

In addition to the features of the building materials intended for the construction of the extension, consideration must also be given to the weight and properties of the material used to construct the main building. The chance of instability and localized shrinkage of the main building’s walls increases with the weight of the added room.

Increasing your living space with foam blocks is a cost-effective and practical way to add an extension to your home. Foam blocks are a great option for this kind of project because they are lightweight, manageable, and offer good thermal insulation. You can make sure that the construction process goes smoothly and successfully by adhering to the suggested steps.

Make sure you have a strong foundation before adding the new structure. Stability and aesthetics need careful planning and alignment with the existing house. Because of their manageable size and weight, building with foam blocks is actually fairly simple once the foundation is ready.

Recall to focus on the little things, like appropriate insulation and sealing. By doing this, you can keep your house energy-efficient and avoid moisture and draft problems. Furthermore, ensuring the longevity and durability of the extension will require using the proper mortar type and adhering to the suggested techniques.

Through meticulous planning and execution of every step, you can use foam blocks to create a cozy and useful addition to your house. This approach provides an affordable way to increase your living space while also saving time and effort.

Adding an extension to your house using foam blocks is a practical and cost-effective solution. Foam blocks are lightweight, easy to work with, and provide excellent insulation. This guide will walk you through the essential steps, from planning and laying the foundation to assembling the blocks and finishing the extension. With some basic tools and a bit of DIY know-how, you can enhance your living space efficiently and effectively.
