Are your Windows Costing you Money? How Upgrading your Windows Could Cut your Bills
Save Money with Affordable Quality Windows in Cumbria
If your home feels draughty in winter, too hot in summer, and noisy all year round, your windows could be to blame. Many older homes across Cumbria still have inefficient windows that leak heat, increase energy bills, and offer little protection from noise and weather.
The good news? Upgrading to Rehau uPVC trade windows is one of the smartest investments you can make. Not only do they improve comfort and security, but they can significantly lower your energy costs, and right now, they’re available at a budget-friendly trade price from Keswick Superglaze.
How Old Windows Could be Costing you More Than you Think
Many homeowners don’t realise just how much their old, inefficient windows are costing them. If you have single glazing or worn-out double glazing, you could be losing up to 30% of your home’s heat through your windows.
Common signs that your windows are costing you money:
- Cold draughts even when the windows are shut.
- Condensation or mould forming on the inside of the glass.
- Rattling in the wind, indicating poor sealing.
- High energy bills that seem to keep rising.
- Outside noise is easily heard inside, showing poor sound insulation.
If any of these sound familiar, it’s time to consider an upgrade—before another winter drives up your heating costs even more.
Why Rehau Trade Windows are a Smart Investment
Not all windows are created equal. That’s why at Keswick Superglaze, we’ve chosen to supply Rehau trade windows, a high-quality, budget-friendly option that delivers long-term savings and comfort.
Here’s what makes them stand out:
Exceptional energy efficiency
Rehau windows have an A WER rating, meaning they keep warmth inside your home while reducing heat loss. This lowers your energy bills and makes your home more comfortable all year round.
Superior weather protection
Made from durable uPVC, these windows won’t rot, warp, or decay like timber, making them ideal for Cumbria’s unpredictable weather. They’re independently tested to achieve high BSI ratings for wind, water, and air resistance.
Low maintenance, long lifespan
Unlike timber windows that need regular painting and sealing, Rehau uPVC windows are practically maintenance-free. They’ll look great and perform well year after year, saving you time and money on upkeep.
Noise reduction
Live on a busy road or near a noisy area? Rehau windows can reduce noise by up to 50%, helping you enjoy a quieter, more peaceful home.
High security standards
Every window is tested for supreme security, giving you peace of mind that your home is well protected.
Great value for money
Rehau windows offer technical quality at a reasonable price, making them a cost-effective upgrade for any homeowner.
