How to Correctly Calculate Gypsum Board

This article presents in table format:

• types of gypsum board for ceiling and wall works;
• calculations of GKL and accessories consumption for various gypsum board structures.

Ceiling Works

Among ceiling works from gypsum board, the most popular include:

• organizing a gypsum board ceiling on a single-level metal frame;
• organizing a gypsum board ceiling on a two-level metal frame;
• organizing a KNAUF-AMF or ARMSTRONG suspended ceiling.

Let's look at the list of required materials and an approximate material consumption for conducting repair works.

Table 2 — Calculation of a gypsum board ceiling on a two-level metal frame

Table 3 — Calculation of a KNAUF-AMF or ARMSTRONG suspended ceiling

Table 4 — Material consumption for organizing gypsum board ceilings

When calculating the cost of materials for simple gypsum board ceiling installation, an average price of $10 per square meter is typically obtained.

Wall Edge Structures

For wall edge structures from gypsum board, the most popular systems include:

• organizing a gypsum board cladding using PERLFIX;
• organizing a gypsum board cladding on a ceiling profile CD 60 frame;
• organizing a gypsum board cladding on a CW and UW profile frame (single-layer).

Let's look at the list of required materials and an approximate material consumption for performing this type of work:

Table 7 — Calculation of gypsum board cladding on a CW and UW single-layer frame

For organizing gypsum board wall edge structures in a typical room with a 4 m by 2.85 m wall, the estimated costs will total $54, i.e., approximately $4.9/m².

Partitions

Before starting the works, determine the desired thickness of the partition: this affects the choice of profile for the job:

• for organizing a single-layer 75 mm / double-layer 100 mm cladding, use UW 50, CW 50 profile;
• for organizing a single-layer 100 mm / double-layer 175 mm cladding, use UW 75, CW 75 profile;
• for organizing a single-layer 150 mm / double-layer 200 mm cladding, use UW 100, CW 100 profile.

Let's look at the list of required materials and an approximate material consumption for performing gypsum board partition works:

How to Calculate Gypsum Board and Other Materials

Material calculations can be done manually or by using a free online service called the "gypsum board calculator".

The gypsum board calculation program already includes a list of all materials needed for the works and their consumption parameters, so the user only needs to select the type of construction they are doing and enter data about the working surface area (ceiling length and width, wall length and height, etc.).

In some programs, you can not only calculate the amount of gypsum board but also get an approximate cost estimate for purchasing all components (both in total and individually).

Cost of Gypsum Board Works

• in Moscow − from 200–250 rubles/m² (depending on type of work / complexity of structure);
• in Kyiv − from 45–60 UAH/m² (depending on type of work / complexity of structure).
