Measuring instructions for Gumax® glass sliding doors
With Gumax® glass sliding doors, you can enjoy even more comfort under your veranda or garden room. Accurate measurement is essential when ordering the correct size sliding doors. You can order Gumax® glass sliding doors in several situations: when ordering them together with a Gumax® veranda, when you already have a Gumax® veranda, or when you have a different type of veranda or garden room. Choose the situation that applies to you and follow the corresponding step-by-step measuring instructions. This ensures that the sliding doors fit perfectly.
To be installed Gumax® veranda
Are you planning to order a Gumax® veranda with glass sliding doors? Then fill in the measuring tool or follow the instructions below to determine which rail system you need for your glass sliding doors.
Determining the width
- Determine the dimensions of your veranda and where you would like to place glass sliding doors. This is the width from support structure to support structure (front) or from wall to support structure (side).
- Refer to Table 1 to see which rail system you need.

Determining the height
Wall profile height
When ordering glass sliding doors, first choose your desired clearance height, for example 2100 mm. Each clearance height corresponds to a specific wall profile height – the height at which the veranda is mounted to the facade. Use the measuring tool to calculate the correct wall profile height so your sliding door fits perfectly.
Clearance height
Do you have limited space on your facade and are therefore restricted to a specific wall profile height? Then use the measuring tool to calculate the corresponding clearance height. This ensures that your Gumax® veranda and your glass sliding doors connect seamlessly.
Do you have any questions about calculating the correct size for your glass sliding doors? Or are you unsure at what height to mount the wall profile? Please contact our customer service advisors via email, phone or WhatsApp.
Installed Gumax® veranda
Has your Gumax® veranda already been installed? and would you like to expand it with glass sliding doors? Then follow the instructions below and use the measuring tool to determine which rail system you need for your glass sliding doors.
Measuring the Width
- Measure the width of the opening where you would like to install the sliding door.
- At the front of the veranda, measure from the inside of one support structure to the inside of the other (see fig. 1).
- On the side of the veranda, measure from the wall to the inside of the support structure (see fig. 2).
- Choose a rail system from Table 2 that is wider than your measured width. You can easily shorten this system yourself.

Measuring the Height
Would you like to install a sliding door on the side (A) or at the front (B) of your Gumax® veranda? Follow the step-by-step instructions below that match your situation.
A – Installing the sliding doors at the side of the veranda:
- Measure the clearance height at the front of the veranda, on the side where you want to place the sliding door. Measure from the top of the foundation or paving to the flat underside of the gutter (see fig. 3 and 4).
- Note: to install glass sliding doors on the side of your veranda, you will need an 8° glass wedge.
- Check Table 3 to see between which values your measured clearance height falls. Select those values when configuring your glass sliding doors on the website.
- Do you want the bottom rail to be recessed into the terrace? Add 18 mm to the clearance height – that’s the height of the bottom rail.
Do you have a sloped terrace? Make sure the surface on which the rail system is installed is completely level. This surface must have a load-bearing capacity of at least 390 kg per linear metre. This can be a foundation tube or another solid base.

B: Sliding door at the front of your veranda
- Measure the clearance height at the front of the veranda. Take measurements at three points (left–centre–right), from the top of the foundation or paving to the flat underside of the gutter (see fig. 5 and 6).
- Take the lowest measured clearance height and check in Table 3 which range it falls into. Select these values when configuring your glass sliding doors on the website.
- Would you like the bottom rail to be recessed into the terrace? Then add 18 mm to the clearance height – this is the height of the bottom rail.
Do you have a terrace with a slope? Ensure that the foundation is level and can support at least 390 kg per linear metre. If you plan to raise or lower your terrace to correct this, make sure to take the clearance height into account when placing your order, so that the sliding door will not be too large or too small during installation.

Example of measuring on the side
- Max measures the clearance height at the front of the veranda at three points: 2100 mm on the left, 2150 mm in the middle, and 2150 mm on the right.
- The lowest measured height (2100 mm) falls within the range of 2080 mm-2120 mm according to Table 3. When ordering the glass sliding doors, he selects this range.
- (Optional) Max wants a recessed bottom rail. His clearance height then becomes 2100 mm + 18 mm = 2118 mm. When ordering the glass sliding doors, he selects the range 2080 mm-2120 mm.
| Passage height | ||
| 1980 mm–2020 mm | 2030 mm–2070 mm | 2080 mm–2120 mm |
| 2130 mm–2170 mm | 2180 mm–2220 mm | 2230 mm–2270 mm |
| 2280 mm–2320 mm | 2330 mm–2370 mm | 2380 mm–2420 mm |
| 2480 mm–2520 mm | 2580 mm–2620 mm | 2680 mm–2720 mm |
External veranda
Do you have a veranda or garden house other than a Gumax® veranda? You can still install glass sliding doors. Measure as follows:
Measuring the width
- Measure the width of the opening where the sliding door will be installed.
- Choose in tabel 4 a rail system that is wider than your measured size. You can shorten this rail system yourself.

Determining the height
- Measure the height of the opening of your veranda where you want to install the sliding doors. Take measurements at three points (left, centre, and right).
- Take the lowest measured height and check between which values it falls in Table 5. Select these values under"clearance height" on the website.
- (Optional) Would you like the bottom rail to be recessed into the patio? If so, add 18 mm (the height of the bottom rail) to your measured height.

| 2480 mm–2520 mm | 2580 mm–2620 mm | 2680 mm–2720 mm |
Do you have a veranda with a slope?
If so, ensure you have a foundation that is level and can support at least 390 kg per linear metre. If you plan to raise or lower your veranda to correct this, make sure to take into account the clearance height you order, so that the glass sliding doors are neither too large nor too small during installation.
Do you have any questions about measuring your glass sliding doors? Please contact our customer service advisors via email, phone or WhatsApp.
Example measurement
- Max measures the height at three points along the front of the veranda: 2100 mm on the left, 2150 mm in the centre, and 2150 mm on the right.
- The lowest measured height (2100 mm) falls within the range 2080 mm-2120 mm according to Table 5. When ordering the glass sliding doors, he selects this range.
- (Optional) Max wants a recessed bottom rail. His clearance height is then 2100 mm + 18 mm = 2118 mm. When ordering the glass sliding doors, he selects the range 2080 mm-2120 mm.

Overlap calculation
Easily calculate the overlap of your Gumax® glass sliding doors:
- Determine how much the rail system needs to be shortened to fit your opening.
- Divide this length by the number of sliding doors minus one.
Example: For a width of 4840 mm, you need a 5-rail system (see table 1). The system length is 4900 mm, so you shorten it by 60 mm. A 5-rail system includes 5 sliding doors, so the overlap is calculated as 60 ÷ (5 − 1) = 15 mm overlap per door.
Want minimal overlap? If your veranda is 3 m deep, choose a 3-rail system with an additional post mounted against the wall. If your veranda is 4 m deep, choose a 4-rail system, also with an additional post.
Foundation
The sliding doors must be installed on a level foundation with a minimum load-bearing capacity of 390 kg per linear metre. This can be a foundation tube or another type of solid base, such as a concrete surface.
