Renovation of the roof structure at the Lakitelek Sports Centre

Our company, GRANDBAU-KER Kft., began renovating the roof structure of the Lakitelek Gymnastics Club in March 2017.

During the works, the existing roof structure was dismantled and a new roof structure was built using new rafters and purlins. A 3-metre covered terrace was constructed on the side of the building facing the main entrance.

As part of the project, our company also carried out paving work, the construction of a covered seating area and drainage works.

Frequently Asked Questions

This is a common misconception. Far from having a shorter lifespan, modern, properly maintained wooden doors and windows often last longer than their plastic counterparts. The combination of high-quality timber, modern surface treatment technologies and precision manufacturing ensures that wooden windows and doors retain their structural stability and aesthetic value for many decades.
👉 It is no coincidence that many historic buildings still feature their original wooden windows today – even after 60–80 years.

A professionally manufactured and fitted wooden door or window has an average lifespan of 40–60 years, but with proper maintenance, this can be even longer. The lifespan is primarily influenced by the following factors:
- the quality of the timber used
- the surface treatment
- the quality of the installation
- regular, yet simple, maintenance
This offers a solution that retains its value better in the long term than most plastic alternatives.

Modern wooden doors and windows do not require complicated or frequent maintenance. Generally speaking:
- occasional cleaning
- surface inspection every few years
- surface refreshment where necessary
This does not involve annual painting or major work, just a little careful attention – in return, the natural beauty and durability of the wood are preserved.

Wood is a natural thermal insulator, making it ideal for the manufacture of energy-efficient windows and doors.
Modern wooden windows and doors:
- offer excellent thermal insulation performance
- provide effective sound insulation
- reduce heating and cooling costs
With the right glazing and precise installation, they create a comfortable, quiet interior space.

The initial investment cost of wooden windows and doors is generally higher than that of plastic ones, but this is offset in the long term by:
- a longer service life
- greater ease of repair
- higher aesthetic and property value
- a natural, timeless appearance
Wooden windows and doors are not mass-produced items, but a durable solution that adds value.
