FAQ
What is the best material for a window frame?
The best material for a window frame largely depends on personal requirements, including climate, budget and style. Wood offers timeless appeal and natural insulation but may require more upkeep. Aluminium is strong and sleek and ideal for a modern look, but less insulating. uPVC is a popular choice for its affordability, low maintenance and good thermal performance. Fibreglass excels in durability and energy efficiency, while composite materials provide a mix of the beauty of wood with the resilience of synthetics. Each material comes with its own set of benefits, allowing for a choice that best aligns with your needs.
Can you DIY fitting window frames?
It’s possible to fit window frames yourself, and it can be a cost-saving option for those with the necessary skills and tools. It requires precise measurements, a clear understanding of the window type and meticulous installation to ensure proper sealing and operation.
While fitting window frames is feasible for experienced DIYers, it's crucial to be aware of local building codes and regulations. Poorly installed windows can lead to energy loss, water damage and decreased home security. For those less experienced, it's recommended to consult with or hire a professional to guarantee the job is conducted correctly and safely.
Do you need Building Regulations for new windows?
Yes, in the UK, new window installations must comply with Building Regulations to ensure they meet safety, thermal efficiency and ventilation standards. These regulations cover aspects such as structural integrity, fire safety (particularly for upper-floor windows) and glazing durability. It's mandatory to use a FENSA or CERTASS certified installer or have the work inspected by Local Authority Building Control. Compliance ensures the windows are installed correctly and that they contribute to the energy conservation of the building, which is increasingly important for environmental and cost reasons. Non-compliance can lead to fines and additional costs to rectify the work.

-
